David S. Goodsell is an Associate Professor of Molecular Biology at the Scripps Research Institute. He received his PhD from UCLA, where he used X-ray crystallography and computer graphics to study the structure of DNA. He now divides his time between biomolecular research and science education. In his research. He develops new computational tools to study the basic principles of biomolecular structure and function. He is currently employing these tools to search for new drugs to fight drug resistance in HIV therapy. He is author of the Molecule of the Month, a feature at the Protein Data Bank that presents a new molecule each month, describing its function and role in health and welfare. His illustrated books "The Machinery of Life" and "Our Molecular Nature" explore biological molecules and their diverse roles within living cells, and his book "Bionanotechnology: Lessons from Nature" presents the growing connections between biology and nanotechnology.
