Biophysicist in Profile MEGAN VALENTINE


Officers President Lukas Tamm President-Elect Angela Gronenborn Past-President Suzanne Scarlata Secretary Frances Separovic Treasurer Kalina Hristova Council

Megan Valentine grew up in the small town of Tamaqua, in the coal regions of northeastern Pennsylvania. Her father worked in a factory that made office furniture, and her mother was a medical transcriptionist. Val- entine was a curious child, interested in how and why the world worked the way it did. “I was naturally drawn to science classes and trivia games when I was growing up,” she says. “I also loved reading about the lives of famous scientists, and particularly physicists who unlocked the secrets of atomic energy and astrophysics.” When she started her undergraduate studies at Lehigh University, she thought she might end up teaching high school science or working in an engineering firm, but after a taste of scientific research, she was hooked. “I decided to major in physics in college, and became involved in polymer physics research, which I found had a great balance of fundamental dis- covery and practical applications to improve technologies and products,” she explains. “Biological materials offer some of the most interesting polymer systems so my interest in biophysics grew from that. Later, I be- came fascinated with how biological systems can move, sense, and actively respond, and how their physical properties enable this.” Valentine was the first in her family to graduate with a bachelor’s degree, receiving her bachelor of science in physics in 1997. She then earned a master’s degree in physics from the University of Pennsylvania in 1999, followed by her PhD in physics from Harvard University in 2003. She went on to work as a postdoctoral fellow in biological sciences at Stanford University, where she studied motor proteins using optical traps.

In 2007, she accepted a faculty position as assistant professor of mechanical engineering at the University of California, Santa Barbara (UCSB), but deferred her start date to 2008 so that she could build sophis- ticated microscopy rooms that provided temperature control in a low noise (acoustic, electromagnetic, vibration) environment. “There were a number of problems with the renovation, and my labs were not completed until 2011. Since I could not pursue the experiments I had proposed in my job application and my tenure clock was running, I started a number of new collaborations and moved my research into entirely new directions. In hindsight, this was seren-

Since 2014, Valentine has been a tenured associate professor of mechanical engineering. Her lab has two main research thrusts. “In the first, we explore the mechanics of living materials, including vascu- lar and neural tissues and marine adhesives derived from mussels, and the regulation of force-generat- ing molecules, like motor proteins,” she explains. “In the second, we aim to make materials that cap- ture the amazing properties of living materials in synthetic materials. Much of this work is currently focused on development of bio-inspired coatings, tough gels, and adhesives. These have applications in dentistry, healthcare, and soft robotics.” Working on such interdisciplinary projects has been a rewarding — yet challenging — proposi- tion. "Since I am collaborating on a broad set of projects, ranging from vascular biology to ma- terials science, I must work hard to maintain a current knowledge of the literature and to develop my professional network in each field,” she says. Another rewarding aspect of her career has been working with students, Valentine says, “Particu- larly students who are first generation to college, for whom obtaining a college or advanced degree will provide enormous opportunities — including opportunities to give back to the community.”

Especially as a young female un- dergraduate physics student, this was a skill I really had to learn. She once pointed out the inflec- tion in my voice when responding to quantitative questions, and I still think of it regularly.” Giving back to her community is important to Valentine. “I make efforts to volunteer and contribute to my community. One organiza- tion I am particularly proud to support is the UCSB Guardian Scholars program, which develops the academic and personal success of students who have been part of the foster care system,” she says. “These

students have faced tremendous challenges and I am honored to be able to provide what I can — whether through financial support, advisement and mentorship, or by simply celebrating their successes.”

As she moves forward in her career, she plans to continue building a strong portfolio of interdisciplin- ary, collaborative research. “I plan to continue my efforts to train a diverse cohort of scientists and engineers to tackle these important problems,” she

“ I must work hard to main- tain a current knowledge of the literature and to develop my professional network in each field. ”

She recently complet- ed a three-year term on the Society’s Early Careers Committee as well. “The Early Careers Committee focuses on providing career and profes-

sional development advice and opportunities for junior members of the Society, including many activities offered during the Annual Meeting,” she explains. “As a postdoc, I was very fortunate to receive a Burroughs Wellcome Career Award at the Scientific Interface, which provided me with great networking and professional development opportunities. I see my work on the committee as a great way to pay that investment forward.”

shares, “and develop the professional skills they need to become the next generation of leaders in industry, academy, and policy.” Veronica Pessino , University of California, San Francisco, worked in Valentine’s lab as an un- dergraduate student.

Public Affairs

Washington, DC. The Biophysical Society is a sponsor of the Award, which honors obscure or odd-sounding federally funded research that led to significant breakthroughs or outcomes, in order to convey the value of basic research and of allowing scientists to pursue independent research interests. Three teams of researchers were recognized for: 1. Research on how mussels stick to surfaces, funded by the US Department of Agriculture, that resulted in a new soy-based glue for ply- wood, replacing a cancer-causing agent. 2. Research on chytrid fungi, which led to unlocking the mystery of mass die-offs of amphibians around the globe. 3. Research into fuzzy logic and fuzzy sets, by a computer scientist funded by the Air Force Office of Scientific Research and the National Science Foundation, that proposed concepts for mathematicians to use to deal with impre- cise knowledge. The findings have been ap- plied to efficiency improvements for HVAC systems and healthcare devices. “The Golden Goose Award reminds us why politicians must leave scientific research to the scientists,” said Jim Cooper (D-TN). “This year’s winners prove how obscure and even unbeliev- able studies can change the world as we know it. We must continue to support our scientists whose brilliance and ingenuity keep America the greatest nation on earth.” BPS Congressional Fellow BPS 2017–18 Congressional Fellow Yasmeen Hussain will be working in the office of Represen- tative Bill Foster (D-IL), handling a broad science portfolio, which could include topics ranging from science education to space to genetics, as well as legislation in front of the House science com- mittee during the coming year. She started her po- sition at the end of September, after a few weeks of orientation and training through the AAAS Science and Technology Fellowship program.

Rally for Medical Research Five Biophysical Society members joined more

than 400 other biomedical researchers, patients, and family members gathered in Washington, DC, September 13–14, to call on Congress to support medical research by providing sustainable, pre- dictable, and robust funding for the National Institutes of Health (NIH). Participants from the Biophysical Society

were Catherine Royer , Rensselaer Polytechnic In- stitute; Kim Ha , St. Catherine University; Vidhya Sivakumaran , Intelligent Medical Objects; Allen Price , Emmanuel College; and Catherine Volle , Cottey College. They were each placed on a team with others from their state to visit congressional offices and make the case for the federal invest- ment in NIH. The Society is a sponsor of the Rally, and the BPS logo was included on the Rally website and at the event. The Society was also listed as a sponsor in a full-page ad that appeared in the Capitol Hill publication, Roll Call , on September 14. In addition, BPS members in the United States were encouraged to participate in a national day of action by sending letters, making phone calls, and posting on social media. Through a call to action sent on September 13, the Society generated 185 messages to Capitol Hill from 54 individuals.

Of Science and Stability Empowering Girls and the Disenfranchised to Build a Lasting Peace

In a society ready to rebuild, BPS member Yuly Sanchez has found a way to use science to engage with those hit hardest by decades of strife. Work- ing with the National University of Colombia’s Social Innovation for Peace project, which seeks to develop strategies for inclusion and promote the social appropriation of knowledge, Sanchez has been leading a project to build up trust, empower- ment, and knowledge for the people of Tumaco. During the 2016 Biophysical Society Annual Meeting, Sanchez connected with BPS Education Committee members and learn about a newly launched Society initiative known as BASICS: Biophysics - A Step-by-Step Introduction to Concepts for Students , which provides lesson plans for K-12 students on elementary biophysical concepts. Dur- ing this meeting, BPS was also able to procure a number of wooden microscopes kits from Chro- ma/Echo Labs, and provide Sanchez with two dozen kits and a lesson plan on light microscopy to take with her. Once back in Colombia, Sanchez put both of these to good use in the Social Innova- tion for Peace program after proposing their use in an activity. Sanchez launched her project on February 11, 2016, on the first annual International Day of Women and Girls in Science. The United Nations General Assembly created the day, which recog- nizes that full and equal access to and participation in science, technology, and innovation for women and girls of all ages is imperative for achieving gender equality and the empowerment of women and girls. According to a recent study conducted at the National University of Colombia, women have low participation rates in the university’s courses related to the quantitative sciences, and are conferred just a small percentage of STEM degrees granted in the country. Since launching her project, Sanchez has worked with more than 200 minority students and has witnessed success in using the hands-on exercise of

Situated in a tropical climate off the Pacific Ocean, Tumaco is a port city and municipality in Colombia’s Nariño Department, located on the southwestern corner of the country. Pre- dominately populated by Afro-Colombians and indigenous peoples, it is an area that has been hit hard by years of conflict between the government, paramilitary groups, narco-traffickers, and left- wing guerrilla forces. As recently as 2015, a series of explosions and attacks left the city virtually disconnected from the rest of the country for days. It is an area that has experienced more than three times the national rate of murders from 2011 to 2013 as a result of guerrilla atrocities and, accord- ing to Human Rights Watch, Tumaco’s rates of poverty, illiteracy, and infant mortality are more than double the national average. Given its history, Tumaco’s residents have been among the most vulnerable people in Colombia. However, in recent years, with a peace process underway, and through government and nongovernmental organization-backed interventions, life is finally beginning to improve in Tumaco.





building wooden microscopes as a way to engage these disenfranchised populations. This past summer, Sanchez was able to continue her efforts in Colombia with the project Scientific Women and Girls Building Peace. Although just one small part of the process, Sanchez’s work to narrow the achievement gap through sparking an early interest in science may ultimately be an essential component of building a lasting peace by offer- ing an entry point for women’s engagement and addressing some of the social inequities that lay at

the root of the conflict. The Biophysical Society has since provided Sanchez with additional microscopes and looks forward to continuing its support of her work and engaging with others like her.

Conformational Ensembles from Experimental Data and Computer Simulations Thematic Meeting

Participants at the Berlin Thematic Meeting had the opportunity to network through multiple poster sessions and social functions.

In August, approximately 170 biophysicists, computational chemists, physicists, biochemists, and structural biology researchers gathered in the Harnack House in Berlin, Germany, for this Bio- physical Society Thematic Meeting. The meeting brought together several different scientific disciplines and communities to discuss and present research concerning conformational ensembles of macromolecules. A particular focus of the meeting was how one can use computational methods together with a highly diverse set of in- tegrative structural biology approaches to produce novel insights into complex biological systems. The meeting had sessions that described state-of- the-art methods for experimental characterization of complex and dynamic biomolecular systems, as well as computational methods to study these systems. Several talks presented recently developed Bayesian and maximum entropy-based meth- ods for integrating increasingly accurate physical models of molecules with experimental data, and pros and cons of the different approaches were discussed in an engaging and constructive man- ner. Other sessions highlighted how integrative structural biology methods, in which numerous

sources of experimental data are combined, can be used to study systems where traditional structural biology approaches have difficulties. The meeting also presented state-of-the-art applications of a wide range of methods, often combined, including Bragg and diffuse X-ray diffraction, SAXS/WAXS, NMR, cryo-EM, single-molecule FRET, chemical cross-linking, and others. Finally, a series of talks described how these methods, when combined with computational analyses and simulations, can produce novel insights into dynamic and confor- mationally heterogeneous systems. Excellent poster sessions culminated in the Bio- physical Journal Poster Awards, being presented to two students and two postdocs for their outstand- ing contributions (see October 2017 Newsletter). The meeting organizers Kresten Lindorff-Larsen , University of Copenhagen; Helen Berman , Rutgers University; Andrea Cavalli , Institute for Research in Biomedicine; and Gerhard Hummer , Max Planck Institute for Biophysics, coordinated 25 invited speakers,12 talks selected from submit- ted abstracts, 120 contributed posters, and hosted participants from five continents.





The 2017 Nobel Prize in Chemistry Goes to… Three Biophysicists! While it might be called the Nobel Prize in Chemistry, three biophysicists have been selected to receive the 2017 award “ for developing cryo-electron microscopy for the high-resolution structure determination of biomolecules in solution. ” The re- cipients, Jacques Dubochet , Joachim Frank , and Richard Hen- derson , have all been members of the Biophysical Society. BPS member Sriram Subramaniam, NIH, noted the timeliness of this award since “we are witnessing an explosion of interest in the application of cryo-EM methods to analyze structures of biological macromolecules.” “It is absolutely terrific that biophysicists Richard Henderson, Jacques Dubochet, and Joachim Frank have been honored with the Nobel Prize in Chemistry this year,” noted BPS President Lukas Tamm in a press release issued by BPS. “By developing cryo-EM into a technique that can now visualize macromolecules and large molecular complexes at near-atom- ic resolution, they have revolutionized structural biology. The resolution revolution that they have unleashed is still unfold- ing before our eyes. Based on their fundamental discoveries and technical developments, we can expect to learn a tre- mendous amount of exciting new biology for many years to come.” With the prize so squarely rooted in biophysics, it’s no sur- prise that many BPS members’ research and careers are based on these earlier findings. David Stokes , a co-chair of the new BPS Cryo-EM Subgroup, reflects on Henderson’s influence on his own career: “I first met Richard at the very first Gordon Conference for 3DEM in 1985. I was finishing my PhD and was interested in working in his lab as a postdoc. He was very approach- able, even for a young grad student. We discussed a potential project and laid out a plan for a fellowship application, which of course involved 2D crystallography of bacteriorhodop- sin. Although that particular application was unsuccessful, Richard helped me find another position in London and encouraged me to use the LMB in Cambridge as a second base, where state-of-the-art EM and computing facilities were available and advice on image reconstruction was generously provided by many renowned scientists. If you wanted to talk to Richard, the best option was to catch him after 8 pm in

the computer room where you could get his full attention for hours on end. His advice was bountiful and the message was always optimistic and full of encouragement. It seemed like everything was doable.” In regards to Frank’s work, Subramaniam commented that “The computational tools that most people use for recon- structing 3D structures from images of individual protein complexes are still based on methods that Joachim Frank pioneered in the 1970’s and 1980’s along with many others such as Marin van Heel and Steve Ludtke , providing a base for further algorithmic developments essential for high resolution structure determination by cryo-EM.” Dubochet, who recently reflected on his early work in electron cryomicroscopy in a Biophysical Journal perspective piece, also has directly affected the work and careers of several BPS members. Subramaniam pointed out that “the experi- mental methods that most people in the field use for prepar- ing specimens for analysis by cryo-EM are still very similar to those pioneered by Jacques Dubochet and co-workers in the 1980’s.” Stokes attributes some of his research success to Dubochet, “I was really lucky to get some early images of vitrified actin filaments from Paula Flicker and Ron Milligan . I was too young and naive to know Jacques Dubochet at that time, but his vitrification technique nevertheless played a very important role in my PhD thesis research and, in fact, in virtually all of my subsequent publications.” Dubochet, an honorary professor of biophysics at the Uni- versity of Lausanne, has been a member of the Biophysical Society since 1996, and has published several articles in Bio- physical Journal . Frank, a HHMI investigator and professor in the Department of Biochemistry and Molecular Biophysics at Columbia University, has been a member of the Biophysical Society since 1992 and a frequent contributor to Biophysical Journal . He has presented his research at the Society’s annual meeting regularly and was named the Biophysical Society’s National Lecturer in 2005. Henderson, Program Leader at the Medical Research Council’s Laboratory of Molecular Biology, United Kingdom, joined the Society in 1994.

Career Transitions The World Outside the Lab:

Professional Development Teaching Science Like We Do Science Sunday, February 18, 2:00 pm –3:30 pm This interactive, hands-on workshop will provide participants with practical tools and evidence- based recommendations for bringing biophysics education to life in the lab, the classroom, and the community. Experienced educators will share their first-hand experiences in brief presentations. The session focus will be on collaborative group discussions, during which participants will design an individualized action plan for implementing active learning techniques and effective assessment strategies in their teaching practice. Moderators will offer guidance and advice on adequate projects for any educational level. How to Project Your Best Self: Confidence Matters Just as Much as Competence Monday, February 19, 2:30 pm –4:00 pm Bringing your best self to interviews, conferences, talks — all aspects of your career — means project- ing confidence. While competence matters, studies show that representing yourself with confidence has a huge impact on success. Women are often less self-assured than men: they underestimate their abilities, they predict that they will do worse on tests than they do, and they are not sure that they are qualified to take that next step. This session will discuss the studies that show this confidence gap, how this gap affects career decisions made by women at multiple stages, and will conclude with strategies to overcome this barrier. Understand- ing the confidence gap concerns not only women, but also anyone who recruits, trains, mentors, or advocates for women.

Many Ways to Use Your PhD Skills Sunday, February 18, 1:00 pm –2:30 pm Have you ever wondered how you can apply the skills learned while working on your PhD in a ca- reer away from the bench? This panel will explore multiple career options that exist in government, industry, and academia. Panelists with science backgrounds, now involved in a wide variety of careers, will share their personal experiences. Industry Panel Monday, February 19, 1:00 pm –2:30 pm Are you interested in pursuing a career in industry? Stop by to hear from a panel of experts who work in bio-related industries. Panelists will discuss how to find, select, and apply for industry internships, providing attendees with useful tools and resources. Postdoc to Faculty Q&A: Transitions Forum and Luncheon Tuesday, February 20, 12:00 pm –2:00 pm This question-and-answer luncheon is designed for postdocs actively applying for academic faculty positions. Discussion will be led by a panel of new faculty in basic science and/or medical school de- partments and experienced faculty who have served as department chairs and/or part of faculty search committees. Topics for discussion include how to prepare the curriculum vitae, the interview process, networking, how to negotiate the job offer, and advice for new faculty as they balance research with their department obligations. To reserve a box lunch, you must pre-register. Attendance is limited to the first 60 participants. Registration is available on the Annual Meeting website.





Fueling Discovery through Biophysics

Funding Opportunities at Primarily Undergraduate Institutions Tuesday, February 20, 12:00 pm –1:30 pm

Call for New and Notable Symposium Speakers

This session is aimed at helping PUI faculty find funding for establishing or maintaining an active and productive under- graduate research laboratory. We Don’t Think the Way We Think We Think: Seeing and Addressing Unconscious Bias and Stereotype Threat Tuesday, February 20, 1:15 pm –2:45 pm This workshop will help participants gain insight into the complex interplay of unconscious bias and stereotype threats, that have a significant impact on the way we perceive, evalu- ate, and behave towards others and ourselves. Participants in the workshop will engage in interactive and reflective strate- gies in a respectful and supportive atmosphere and will gain an awareness of individual strategies to protect themselves from being influenced by unconscious or unintended biases. Leveling the Playing Field is a new series of annual work- shops designed to increase your skill in addressing the barriers faced by women in science. Are you all in favor of increasing professional opportunities of women but don’t know how to contribute? These ’hands-on’ sessions can help you to become more effective in improving the climate for women in bio- physics at all stages of their careers. The 2018 workshop aims to increase your effectiveness in raising awareness of the scientific contributions of women in biophysics, using social media and other means. “ Undergraduate workshops and Q&A sessions helped me think through upcom- ing decisions and allowed me to interact with accomplished biophysicists.” ” Leveling the Playing Field Tuesday, February 20, 2:30 pm –4:00 pm

The Biophysical Society is seeking suggestions from Society members for speakers to be featured in the annual New and Notable Symposium in San Francisco. This symposium is unique in that, through a series of brief talks, attendees hear about late-breaking and exciting science. Unlike other symposia, which are planned at least nine months before the meeting, the New and Notable Sympo- sium program is not finalized until December. If you have a colleague who should be considered, visit and complete the required information fields by December 4, 2017.

Molly Cule

Remember, you are in charge of your future. You must be transparent, honest, and direct in your communication with your advisors and mentors about your position and how they can help you succeed. You are ultimately responsible for your own development, so make sure you surround yourself with trusted mentors who will provide the support and guidance you need for success. There are a number of resources for scientific mentors and mentees that cover every stage of a career and are freely available from the Howard Hughes Medical Institute, Burroughs Wellcome Fund, AAAS, the National Academy of Sciences, Nature , and Science . Take advantage of the re- sources available to you to help create a productive relationship. — Molly Cule

Creating a Productive Mentor-Mentee Relationship Scientific and emotional mentorship is a criti- cal part of career development and professional success. Therefore, creating a productive mentor- mentee relationship is an important part of your career development plan that deserves discussion. In the best of cases, mentor-mentee relationships organically develop in a positive direction as you grow your career in a successful training environ- ment. However, there is the alternative situation when mentor-mentee relationships are less than organic, or sour as time goes on for various rea- sons. These difficulties can complicate interactions with your mentor and put you in the position to look elsewhere for guidance and mentorship — a process that will require your vision and explora- tion. There are many cases where mentees need to mix and match internal mentorship (sound and trusted advisors within your department, university, or place of employment) with external mentorship (sound and trusted advisors outside your place of work). If you end up with a mix of mentors, don’t feel like a disappointment to your- self, your training program, or your employment team — rather, just embrace the opportunity to communicate with multiple people who can help you succeed. Sometimes, these additional mentors can help you resolve communication issues with your advisor or mentor, and can offer you extra support to help you accomplish your goals.
