Assistant Professor of Chemistry
Current Research and Scholarly InterestsResearch in our group explores the boundaries of modern organic synthesis to enable the more rapid creation of the highest molecular complexity in a predictable and controllable fashion. We are particularly inspired by natural products not only because of their importance as synthetic targets but also due to their ability to serve as invaluable identifiers of unanswered scientific questions.
One major focus of our research is selective halogenation of organic molecules. Dihalogenation and halofunctionalization encompass some of the most fundamental transformations in our field, yet methods capable of accessing relevant halogenated motifs in a chemo-, regio-, and enantioselective fashion are lacking.
We are also interested in the practical total synthesis of natural products for which there is true impetus for their construction due to unanswered chemical, medicinal, biological, or biophysical questions. We are specifically engaged in the construction of unusual lipids with unanswered questions regarding their physical properties and for which synthesis offers a unique opportunity for study.
Associate Professor of Microbiology and Immunology
Current Research and Scholarly InterestsOur research focuses on the identification of host genes that play critical roles in the pathogenesis of infectious agents including viruses. We use haploid genetic screens in human cells as an efficient approach to perform loss-of-function studies. Besides obtaining fundamental insights on how viruses hijack cellular processes and on host defense mechanisms, it may also facilitate the development of new therapeutic strategies.

Current Research and Scholarly InterestsOur research program integrates chemistry, biology, and physics to investigate the assembly and function of macromolecular and whole-cell systems. The genomics and proteomics revolutions have been enormously successful in generating crucial "parts lists" for biological systems. Yet, for many fascinating systems, formidable challenges exist in building complete descriptions of how the parts function and assemble into macromolecular complexes and whole-cell factories. We are inspired by the need for new and unconventional approaches to solve these outstanding problems and to drive the discovery of new therapeutics for human disease.
Our approach is different from the more conventional protein-structure determinations of structural biology. We employ biophysical and biochemical tools, and are designing new strategies using solid-state NMR spectroscopy to examine assemblies such as amyloid fibers, bacterial cell walls, whole cells, and biofilms. We would like to understand at a molecular and atomic level how bacteria self-assemble extracellular structures, including functional amyloid fibers termed curli, and how bacteria use such building blocks to construct organized biofilm architectures. We also employ a chemical genetics approach to recruit small molecules as tools to interrupt and interrogate the temporal and spatial events during assembly processes and to develop new strategies to prevent and treat infectious diseases. Overall, our approach is multi-pronged and provides training opportunities for students interested in research at the chemistry-biology interface.
Howard Y. Chang, MD PhD
Virginia and D. K. Ludwig Professor of Cancer Genomics and of Genetics
Current Research and Scholarly InterestsOur research is focused on how the activities of hundreds or even thousands of genes (gene parties) are coordinated to achieve biological meaning. We have pioneered methods to predict, dissect, and control large-scale gene regulatory programs; these methods have provided insights into human development, cancer, and aging.
Assistant Professor of Mechanical Engineering
BioOur group's research is focused at the intersection of mechanics and biology. We are interested in elucidating the underlying molecular mechanisms that give rise to the complex mechanical properties of cells, extracellular matrices, and tissues . Conversely, we are investigating how complex mechanical cues influence important biological processes such as cell division, differentiation, or cancer progression. Our approaches involve using force measurement instrumentation, such as atomic force microscopy, to exert and measure forces on materials and cells at the nanoscale, and the development of material systems for 3D cell culture that allow precise and independent manipulation of mechanical properties.
James K. Chen
Professor of Chemical and Systems Biology and of Developmental Biology and, by courtesy, of Chemistry
Current Research and Scholarly InterestsOur laboratory combines synthetic chemistry and developmental biology to investigate the molecular events that regulate embryonic patterning, tissue regeneration, and tumorigenesis. We are currently using genetic and small-molecule approaches to study the molecular mechanisms of Hedgehog signaling, and we are developing chemical technologies to perturb and observe the genetic programs that underlie vertebrate development.
Professor of Photon Science, Bioengineering and of Microbiology and Immunology
Current Research and Scholarly InterestsMy research include methodology improvements in single particle cryo-EM for atomic resolution structure determination of molecules and molecular machines, as well as in cryo-ET of cells and organelles towards subnanometer resolutions. We have collaborations with many researchers around the country and outside USA on understanding biological processes such as protein folding, virus assembly and disassembly, pathogen-host interactions, signal transduction, transport across cytosol and membrane.
Professor of Medicine (Oncology) and of Biochemistry
Current Research and Scholarly InterestsOur laboratory seeks to understand how cells repair DNA damage. We currently focus on how non-homologous end joining proteins assemble on DNA ends to juxtapose them for repair of DNA double-strand breaks.
We are collaborating on a point-of-care device to measure ammonia from a drop of blood. The device will facilitate diagnosis and management of urea cycle defects, liver disease, and chemobrain due to elevated ammonia.
