What were you doing before you came to the NSF?

I am currently a Staff Scientist at Los Alamos National Laboratory  (LANL) in Los Alamos in NM, and also an Adjunct Professor at Department of Chemical Engineering at UC Davis. In general, my area of scientific expertise covers using neutron and x-ray scattering to investigate nano- and meso-structures, including bio-interfaces (lipid membranes, interaction of membranes with bio-toxins, Langmuir-Blodgett monolayer films films and living cells) and soft-matter systems (polymers, etc.) in different environments. At LANL I was also involved in many aspects of solid-state physics and science connected with national security and actinides properties. I am currently an American Physical Society (APS) and Neutron Scattering Society of America (NSSA) Fellow.

What attracted you to work for the NSF?

I was interested to explore new career avenues as well as to use my experience to influence science outside the lab.

What was your first impression of the NSF? Has this impression changed since you began serving as a rotator?

My first impression was that NSF is a well-functioning institution with a friendly working environment and well-deserving of its impressive reputation. The organization has a clearly established mission, well-trained personnel, and extremely nice people all around. My first impression has only changed in that these observations have become even more evident over time!

What personal goals would you like to accomplish while at the NSF?

I would like to use my time at NSF to learn how science is supported from the view of a funding agency. I am interested to see the ways NSF uses to get to know the community we support  and to understand their scientific needs. I hope to obtain a more global picture of how federal agencies like NSF work and use this information to develop connections and knowledge. I also hope to visit the scientific places NSF supports and to better understand the scientific outcomes of the funded research..

What has surprised you most about working at the NSF?

That such tremendous work is done is such short time and with such efficiency. I have been continually impressed by the tight connection between the science communities and NSF Program Directors who support them. I have also been impressed at the huge spectrum of expertise, experiences, and ideas of the NSF staff.

What are some of the challenges of serving as a rotator?

I have to admit that the beginning was rather overwhelming: to learn so many new things in a short time (the panel season was approaching when I started) and to deal with/memorize/try to understand the science described in the proposals while knowing that any decision might be consequential for science. I was fortunate to have the support of my fellow Program Directors through this time and have learned so much.

What would you tell someone who is thinking about serving as a Program Director at the NSF?

It is a tremendously rewarding job but a lot different from regular activities of a scientist. It is a job well-suited for people who have a lot of experience in the scientific community and know their science well – I still find myself needing to learn many things at NSF despite my 20+ years’ experience as a scientist.

When friends or colleagues find out that you work at the NSF, what do they say or ask?

My friends and family, even those not as familiar with the extent of NSF’s work, are very impressed and think that working at NSF is very noble.

MCB recently gave a congratulatory sendoff to Dr. Gregory Warr, who has retired from NSF after 10 years of dedicated service. Dr. Warr started at NSF in 2007, serving for a short period as a Program Director in the division of Integrative Organismal Systems (IOS) before transferring to MCB, where he served as a Program Director and cluster leader for Cellular Dynamics and Function (CDF). During his tenure in MCB, Dr. Warr also temporarily served as acting Division Director, bringing his dedication for quantitative methods into his work as an MCB leader.

Dr. Warr was a strong advocate of MCB’s emphasis on quantitative, predictive and theory-driven science and this was well reflected in the portfolio developed in the CDF cluster, where projects emphasized quantitative approaches and modeling. Dr. Warr’s advocacy has also had effects across MCB. According to Dr. Karen Cone, Acting Deputy Division Director, one of his most important contributions to MCB was “his recognition, early on, that the Division was supporting many projects using network analysis to understand regulatory processes, but these projects were dispersed across the existing three clusters.  His insights helped spur creation of a new cluster, Networks and Regulation, which eventually was re-named the Systems and Synthetic Biology Cluster and supports a portfolio of vibrant projects well-grounded in quantitative and predictive science.”

Dr. Warr’s droll sense of humor will be sorely missed, but his influence on how the Division operates will continue. Dr. Theresa Good, Acting Division Director, says, “I appreciate both his ability to see strategically what was happening in the Directorate and Foundation and [to] act in ways that strengthened the Division, and his skill in enabling people who work with him to grow. Greg sought out the best people to have working with him, so that the Division could benefit from their expertise. He was a true intellectual and scholar with a wide range of interests far beyond just the science we fund.”

MCB thanks Dr. Warr for his hard work and dedication to the Division and MCB science. We will also miss his inspiring 6 AM gym schedule and ability to point out the silly absurdities in our everyday lives. Dr. Charles Cunningham, fellow Program Director and longtime friend, says that he will most miss two things: “Firstly, having been in MCB for 10 years or so, there was little he did not know when it came to process, so he was this great fund of information. Second, our chats about science, politics and home, especially over a curry and a glass of something refreshing at the Bombay Club in DC.”




I headshot style photo of Michael, he is smiling into the camera. He is wearing a blue shirt and glasses and is siting in a library with shelves, a computer, and students strudying in the background.

What were you doing before you came to the NSF?

I was an associate professor in the Laboratory of Genome Integrity and Tumorigenesis at the Van Andel Research Institute in Michigan for 16 years, having joined the Institute at its founding in 2000. After moving to Boston for my wife’s Palliative Care Fellowship at Harvard Medical School, I closed down my lab and joined Phil Sharp’s lab at MIT as a visiting scientist.

What attracted you to work for the NSF?

I was funded by the NSF some years ago and saw the immense impact that it had on my ability to complete meaningful research. In my work as panelist, I came to know more about NSF and to appreciate its vital role for supporting basic science and education in the US. All my interactions with the staff and scientists here were very positive, so that led me to have an even higher opinion and appreciation for the mission of the NSF.

What was your first impression of the NSF? Has this impression changed since you began serving as a rotator?

While serving as a panelist, I saw NSF as an efficient and effective organization, and my first impressions after joining as a rotator confirmed these views. Although the steep learning curve of joining MCB in the middle of the grant review cycle was a bit overwhelming, my overall thoughts on NSF have not changed.

What personal goals would you like to accomplish while at the NSF?

I would like to support NSF’s mission, “to promote the progress of science; to advance the national health, prosperity, and welfare; to secure the national defense…”¸ by making funding decisions that have a positive impact on science in the MCB community, and hopefully positive effects throughout the country. I also want to learn more about the history of the NSF and the breadth of its activities to promote science and the public good.

What has surprised you most about working at the NSF?

What surprised me is that I could walk down to the 3rd floor with my laptop and someone would help me fix the problem immediately! The IT staff is great.

What are some of the challenges of serving as a rotator?

While BIO/MCB may seem relatively small, NSF is a mid-level federal agency with over a 1,000 employees, which means there are a wide range of projects in many different areas of science. One challenge has been learning about and keeping track of all the directorates, divisions, and wide range of opportunities at NSF.

What would you tell someone who is thinking about serving as a Program Director at the NSF?

Please consider it seriously. Serving as a Program Director allows researchers to gain more insight into the breadth of scientific research (even within your own field) and also how to write a better grant proposal.

When friends or colleagues find out that you work at the NSF, what do they say or ask?

They think my new role poses both unique challenges and opportunities and that it will be a great experience.

What were you doing before you came to the NSF?

I am a Professor in the Department of Biology at Pomona College in southern California, and teach biochemistry, microbial ecology, and cell biology courses. My research team and I study the microbiology and biochemistry of sulfur-based respiration in natural environments, such as sediment from the deep sea and mud volcanoes from hot springs.

What attracted you to work for the NSF?

I enjoyed serving as a panelist on merit review panels. As a panelist, I saw so much new science and the intensity of going over proposals in detail in a relatively short period of time appealed to me. Also, it seemed like being a program officer would be a real challenge. It is so different from the experience that one has as a professor – where you can still feel very isolated even though you are interacting with your research group and a lot of students.

What was your first impression of the NSF? Has this impression changed since you began serving as a rotator?

My first impression after serving on merit review panels was positive; it hasn’t changed. Coming to NSF as a rotator was a pretty big move for me, so I researched the position. I asked questions when I visited the NSF and talked to former program officers that I know – everyone said that it’s a hard job, but that it’s worth doing due to the amount you learn and the ability to impact the direction that science takes.

What personal goals would you like to accomplish while at the NSF?

In the past, I tended to focus on scientific areas directly related to my research, so I’m hoping to learn to think much more broadly about where the natural and physical sciences are going and how different disciplines collaborate and complement each other. I’d also like to think more about where science could be going in the future.

What has surprised you most about working at the NSF?

What surprised me is the amazing efficiency of NSF. From the staff handling the logistics of the proposals and review panels, to the person running the office, to the IT staff – anytime you have a question or problem it gets dealt with immediately and correctly. It makes it much easier for program directors to focus on science.

What are some of the challenges of serving as a rotator?

I think the biggest challenge so far is not having my research lab right next door where I can go and be a part of my students’ daily lives and work when I get tired of being in my office. For me, much of the fun of science is working in the lab, so I miss not having cultures to look at in the microscope, not being able to spend a few hours with my students constructing and troubleshooting an experiment, or even the excitement of viewing new results such as looking through sequencing data to see what kinds of new microbes we may have discovered.

What would you tell someone who is thinking about serving as a Program Director at the NSF?

I’d tell them that if they’ve had experience with the merit review process as a panelist or reviewer and enjoyed it, they would most likely be a good fit at NSF. Having experience writing proposals is also important – if a person does not enjoy writing proposals, they’re probably not going to enjoy looking at them all day long!

When friends or colleagues find out that you work at the NSF, what do they say or ask?

I was kind of surprised at their responses. Almost everyone asks, “So what is your average day like? What do you actually do all day?”

A Word from Dr. Theresa Good, Acting Division Director


As many of you may know, our Division Director, Dr. Linda Hyman, recently returned to her previous position as Associate Provost for the Division of Graduate Medical Sciences at Boston University. Linda led MCB through some difficult times: the death of a dear friend and colleague, Dr. Kamal Shukla; the retirement of a dedicated colleague and advocate for the synthetic biology community, Dr. Susanne Von Bodman; and the transition of a number of staff members into different roles within the Foundation and elsewhere in federal service. From all of us at MCB, thank you Linda, for the time you took away from your role at Boston University to lead us and for your year and a half of service to the Foundation. Good luck as you return back to Boston University.

As I now take on the role of Acting Division Director, I am thankful to have the support of talented program directors, staff, and colleagues, like Dr. Gregory Warr, who have previously served in this role.  All are dedicated to the NSF mission of transforming the frontiers of science and engineering, and stimulating innovation to address societal needs through research and education. While change is occasionally uncomfortable, it often brings about opportunities. We are excited to have a number of new program directors who you will meet over the coming months (Dr. E.J. Crane, Dr. Michael Weinreich, and Dr. Jarek Majewski), new staff members (Grace Malato), and the expert leadership of a new Operations Manager (Dr. Reyda Gonzalez-Nieves). Two of our dedicated program directors, first Dr. Michelle Elekonich, and then Dr. Karen Cone, will serve as the acting Deputy Division Director in two respective 120 day rotations. Michelle and Karen both have experience in division leadership and will work with me to ensure the efficient operations and attention to science vision for which MCB is known.

In addition, a new solicitation will be issued and some new workshops are being developed to catalyze conversations about the future directions of MCB science. Within MCB, we are poised to do our part to invest in science, engineering, and education for the nation’s future.

We look forward to engaging the scientific community during panels, meetings, and outreach visits about how to best serve science and the needs of the nation. We ask you to continue to work with us by: submitting your best ideas in proposals, continuing to participate in peer review, serving on panels, meeting with us at NSF workshops or at other scientific meetings, serving as rotating program directors, continuing to do outstanding research and broader impacts activities, and communicating the results of those efforts to the broader community.

As always, MCB welcomes your questions and input on how we can better serve the scientific community. You should always feel free to give us feedback or reach out to a program director with questions.


Best wishes,


Dr. Theresa Good

Acting Division Director

Hear from MCB biologist Grace Malato.

What is your educational background?

I received my Bachelor of Science degree in Wildlife Biology with an emphasis in Aquatics from the University of Montana, Missoula. I then received my Master of Science degree in Biology from DePaul University in Chicago, Illinois.

What is your position? When did you start working in MCB?

I started as a Biologist for MCB in January 2017, just after the New Year. I am here as a Presidential Management STEM Fellow (PMF STEM), which is a program that we previously featured on the MCB blog.

What attracted you to work for NSF?

I have had the opportunity to work in a variety of research settings that combine molecular tools with ecological concern; I love the excitement that comes with discovery. After seeing how important but challenging interdisciplinary research can be, I was curious about the bigger picture. I am excited to work at NSF to contribute to the scientific community at large and to be a part of an organization providing critical funding for innovative research.

What have you learned so far from your position?

I have learned, in my short time at NSF, so much about the inner workings of the merit review process as well as how funding and research priorities are set. I have learned just how much work goes into reviewing proposals as well as how decisions on funding influence the future of science.

What were you doing before you came to the NSF?

I am a staff scientist at the Carnegie Institution for Science, Department of Plant Biology, which is a full-time research position, and I have a courtesy appointment as a Professor in the Department of Biology at Stanford University. I mentor both graduate and undergraduate students, collaborate with several faculty, and teach a range of courses.

What attracted you to work for the NSF?

Well, a number of things. I have been funded for most of my career by the NSF. NSF support allowed me to get back into research (after several years in India) and to develop several interdisciplinary projects. I felt this was a good time in my career to use my experience to help identify the most innovative science. Being a rotator allows me to explore the complex funding landscape, which may help me better develop future research projects. I also think strong interactions between scientists and funding agencies can bring in new ideas.

What was your first impression of the NSF? Has this impression changed since you began serving as a rotator?

I came in the day before the start of a panel, which was a bit overwhelming, but prepared me for what lies ahead. I was struck by the collegiality among the Program Directors and the professionalism of the staff. If anything, I am now even more impressed because I realize that everyone is trying to do their best, under sometimes challenging circumstances.

What personal goals would you like to accomplish while at the NSF?

I am deeply immersed in my own research, but I have become more curious about how all the pieces of the foundation fit together and how policies and directions are decided.  That’s hard to see from the “outside”, and I have already been able to get a better sense by attending seminars, retreats, and meeting people. I also felt this experience would allow me to decide whether or not I could make a difference and be happy in a longer term position at the NSF or one of the other funding agencies in the latter part of my career.

What has surprised you most about working at the NSF?

What surprised me most are the various opportunities that exist at the NSF if you can take time out of a busy schedule. I’ve been able to meet academics and Program Directors from different fields, talk to young scientists about their career goals, and attend several talks – all in the first few months! I have also been surprised at how much organizational flux there is with new people joining and others leaving; yet all the programs still run efficiently.

What are some of the challenges of serving as a rotator?

So far, the challenge has been learning the ropes (software, processes, etc.). In the future, I see the bigger challenge to make the best funding decisions. But in both cases, the fact that there are several experienced Program Directors who are always willing to answer questions and discuss issues is a huge help. This role is very different from being an established academic where one is familiar with the territory.

What would you tell someone who is thinking about serving as a Program Director at the NSF?

Serving as a Program Director is a unique opportunity to witness firsthand how much thought, complexity, and effort lies behind funding decisions. I would recommend early or mid-career scientists serve if they can afford to take the time. I’d especially encourage those who like challenges, are curious, and like to cross both social and scientific boundaries. To use an analogy – doing one’s own research is like focusing on a single star; at the NSF, you realize there are whole galaxies out there and enjoy the “big picture.”

When friends or colleagues find out that you work at the NSF, what do they say or ask?

For most of my scientist friends, working at the NSF represents the daunting challenge of using scarce resources to promote excellence in basic science and build diversity. There are some who say I must be a risk-taker who likes a challenge, but others who think I have a great opportunity to contribute to and strengthen the science community. Frankly, I think it’s a bit of both and I am eager to see how my perspectives change over the next few months.
