Carla Williams, Ph.D.

Associate Professor of Medicine & Public Health, Howard University

Interim Director, Howard University Cancer Center, Graduate School 

Carla Williams received her Ph.D. in clinical psychology from Howard University. She is currently Associate Professor of Medicine and Public Health and Interim Director of the Howard University Cancer Center. Her work centers around understanding and reducing cancer-related health disparities. Her research activities emphasize engaging communities that have not been adequately represented in research.  Dr. Williams works with community health leaders to promote individual adoption of healthy lifestyle behaviors as well as population-level change in the environment, health policies, and health systems.

Since 2010, Williams’ collaborative research efforts have resulted in the expansion of her role to function as an Executive Scientist. In this capacity, she helps to build research teams within and across institutions to promote collaborative research. She has led the development of a regional symposia to equip scientists and community health advocates with the skills to maximize the impact of collaborative research. 

In her teaching roles, Williams has developed new training paradigms to enhance students understanding and utilization of evidence-based practice. She has also incorporated the use of reflective exercises to promote learning synthesis and integration.  Most recently, she has worked to develop a combined didactic and practice-based course that builds skills for community engagement as a key discipline in public health, health care research, and health policy.

Mary Kearney

 Senior Scientist and Head, Translational Research Section  

Deputy Program Director, HIV Dynamics & Replication Program, National Cancer Institute

Mary Kearney received her B.A. in Biochemistry from Hood College in 1996 and her M.S. in Biomedical Science from Hood College in 2001. In 2008, she received a Ph.D. in Biology from Catholic University and was awarded the Benedict T. DeCicco Award for Excellence in Graduate Research. Dr. Kearney has been an integral part of the HIV Dynamics and Replication Program since 2001.

In 2008, Dr. Kearney was promoted to Head of the Translational Research Section where she oversees a team that investigates viral genetics and expression in vivo, the sources of persistent HIV during antiretroviral therapy (ART), the sources of rebound viremia after stopping ART, the mechanisms for maintaining the HIV reservoir, and the mechanisms for the emergence of drug-resistance mutations in HIV and other RNA viruses. Key discoveries include demonstrating that ART is fully effective at blocking HIV replication in vivo, that HIV persists through cellular proliferation of cells that were infected prior to ART initiation, and that HIV has differential expression among cells within infected cell clones.  

Dr. Kearney is the recipient of four Bench-to-Bedside Awards, three NIH Intramural AIDS Targeted Antiviral Program Awards, a U.S.–South Africa Initiative U01 Grant, an Office of AIDS Research Congressional Award, and an NCI Flex Technology Award. In 2019, she was promoted to Senior Scientist and in 2021 to Deputy Program Director of the HIV Dynamics & Replication Program.   

Woman in science role model

“A famous woman in science who I view as a role model is Dr. Beatrice Hahn at the University of Pennsylvania. Dr. Hahn discovered the origin of HIV and traced its spread and evolution in humans using unique strategies, among many other important discoveries. She made these discoveries when women still had very little support in science and while raising four children. She is very supportive of other women in science.”

Woman in science role model

"My role model is Rosalind Franklin. Learning of the contributions she made towards understanding the structure of DNA, without the accolades and acknowledgment she deserved, really shaped my approach to science as a woman and as a person. Science is a collective effort and innovation involves everyone who contributes, not just those in the spotlight."

Ruth Nussinov, Ph.D.

Senior Prinicipal Scientist and Head, Computational Structural Biology Section

Born in Rehovot, Israel, Ruth Nussinov pioneered the “conformational selection and population shift” (1999) as an alternative to the “induced fit” text-book model to explain molecular mechanism of recognition and posited that population shift underlies allosteric regulation. She extended this pre-existing ensemble model to catalysis (2000), and oncogenic activation, contributing to extraordinary advancements in understanding structure and function.  

Dr. Nussinov received her Ph.D. in 1977 from Rutgers University and did post-doctoral work in the Structural Chemistry Department of the Weizmann Institute. Subsequently she was at the Chemistry Department at Berkeley, the Biochemistry Department at Harvard, and a visiting scientist at the NIH.  

In 1984 she joined the Department of Human Genetics, at the Medical School at Tel Aviv University. In 1985, she accepted a concurrent position at the National Cancer Institute of the NIH, Leidos Biomedical Research, where she is a Senior Principal Scientist and Principle Investigator heading the Computational Structural Biology Section.  

She has authored over 700 scientific papers. She is the Editor-in-Chief of Current Opinion in Structural Biology, was the Editor-in-Chief of PLoS Computational Biology, is currently the Editor-in-Chief of Current Opinion in Structural Biology and Associate Editor and on the Editorial Boards of a number of journals.  

She is a frequent speaker in Domestic and International meetings, symposia and academic institutions, won multiple awards and elected fellow of several societies, and has been twice a highly cited researcher. Her National Cancer Institute website gives further details.

Woman in science role model

"More of an admiration rather than a role model – Marie Skłodowska Curie. A true, unapologetic pioneer! Pioneered the field of radiochemistry, discovered polonium and radium, first person to win the Nobel Prize in two scientific fields, first woman to win a Nobel Prize, driven to apply her discoveries for care (developing mobile units to provide X-rays during WWI), fueled a family legacy, and she’s Polish like me.

P.S. How cool to have an element named after Poland, when it wasn’t an independent country at the time? She used her platform to make a statement."
