The Convergence of Chemistry & Human Biology

Chaitan Khosla

Over the past two decades, “chemical biology” has emerged as the term of choice to describe the interface between chemistry and biology. As its name suggests, the field draws upon chemical insights and tools to understand or engineer living things. This essay focuses on the scientific, societal, and pedagogical potential of an emerging frontier for chemical biologists: namely, the study of Homo sapiens. My goal is to highlight the opportunities and challenges presented to chemistry by human biology at a time when it costs less to sequence an individual's genome than it does to buy a car. But how does chemical biology differ from other similar-sounding fields? By first reaching a clear understanding of the scope of chemical biology, we may address more pertinent questions such as: What is the promise of the emerging interface between chemistry and human biology? Why is it important to nurture the relationship between these fields? And what are the attributes of individuals and environments that are well poised to contribute significantly to this interface?

CHAITAN KHOSLA, a Fellow of the American Academy since 2007, is Professor of Chemistry, Chemical Engineering, and (by courtesy) Biochemistry at Stanford University. He also directs Stanford ChEM-H, an institute that brings together chemists, engineers, biologists, and clinicians to understand life at a chemical level and apply that knowledge to improving human health. His work on antibiotic biosynthesis and the molecular basis for celiac disease has been published in Science, Journal of the American Chemical Society, and Proceedings of the National Academy of Sciences, among many others.
