Dr. Catherine D. Lewis

Catherine D. Lewis, director of the NIGMS Division of Cell Biology and Biophysics (CBB), retired in January after more than 30 years of service at the NIH. Throughout her career, Cathy was widely recognized for her scientific foresight and leadership, including the early recognition of important emerging research opportunities in molecular biology, biophysics and microscopy. Her tireless work behind the scenes ensured that these transformational new research approaches were seamlessly integrated into the NIH portfolio and able to grow rapidly.

Cathy earned an M.S. and Ph.D. in biochemistry from Princeton University and joined NIH in 1983 as a staff fellow at NIDDK in the lab of Gary Felsenfeld, where she studied chromatin structure and the regulation of beta-globin gene expression during development.

Her career at NIGMS started in 1989, when Cathy moved to the Institute as a program director in the Genetics Division—led at the time by Judith Greenberg. She managed grants on cell nuclear structure and function and was instrumental in the development of programs focused on epigenetic regulation. Eight years later, Cathy became CBB’s Biophysics Branch chief. In that role, she at one point managed nearly 400 grants, some of which led to breakthroughs such as the structure of the ribosome. She also initiated NIGMS programs focused on new single-molecule methods and nanotechnology. In 2006, Cathy took over as director of CBB. During this period, she oversaw changes in the direction of the NIGMS Protein Structure Initiative, promoted advances in high-resolution optical microscopy and cellular imaging, and led efforts to support atomic resolution cryo-electron microscopy, including a new Common Fund initiative.

During her tenure at NIH, Cathy received two NIH Director’s Awards, for her work on trans-NIH initiatives and her leadership on science education in elementary schools.

Cathy’s door was always open to all, and her advice was constantly sought by colleagues, not only in her own division, but widely across NIGMS and NIH.

Most importantly, Cathy maintained warm professional and personal relationships with those around her, while getting things done and influencing others. “Leading a division that worked well and where people respected each other and got along is something that I’m happy to have been involved in,” she says.

Working in the CBB division was fun, because she helped make it so. She will be missed.

Emergence of Quantitative and Systems Pharmacology: A White Paper

Our interest in quantitative and systems pharmacology (QSP) began in 2007 as a question about why we were seeing so little integration between two fields we fund: systems biology and pharmacology. We recognized that connecting them could improve our understanding of drug action and speed drug discovery and development while also increasing our scientific understanding of biology.

To examine the potential of quantitative, systems approaches to pharmacology research, we sponsored two workshops in this area, one in 2008 and the other in 2010. After the second meeting, a committee of external scientists who were also workshop participants began drafting a white paper to assess the state of the science and enumerate the opportunities, needs and challenges for QSP as an emerging discipline.

The committee recently issued the white paper.

The paper makes the case that this post-genomic era is the right time to develop and employ quantitative, systems approaches to understand drug action more predictively, and that the need and excitement for doing so is building. Already we are starting to see evidence of this field emerging—the University of California, San Francisco, has started a Center for Quantitative Pharmacology Link to external web site, and Harvard Medical School just announced an Initiative in Systems Pharmacology. Also, the American Association of Pharmaceutical Sciences annual meeting Link to external web site this month will include a session called, “Achieving the Quantitative and Systems Pharmacology Vision.”

The overall recommendation of the workshop committee is for pharmacology to move beyond characterizing drug/target interactions to a holistic quantitative understanding of drug action across many levels—from drug-receptor interactions to drug response in humans. As stated in the paper, this will require the participation of scientists from academia and industry who work in diverse areas, including traditional pharmacology, clinical pharmacology, pharmacodynamics/pharmacokinetic modeling, systems biology, chemistry, bioinformatics, multiscale modeling and computer science. Training new and established investigators also will be a critical element.

We encourage you to read the paper and let us know what you think about its recommendations for research and training in QSP.
