Nathan S. Lewis, George L. Argyros Professor at the California Institute of Technology, has made significant contributions to the fields of photoelectrochemistry and chemical vapor sensing. He earned his Bachelor of Science and Master of Science degrees from Caltech in 1977, followed by a Ph.D. from the Massachusetts Institute of Technology in 1981. Lewis has held various academic appointments at Caltech, progressing from Associate Professor to full Professor and ultimately to the Argyros Professorship. His research group focuses on semiconductor photoelectrochemistry and the development of electronic noses, which employ arrays of chemically sensitive conducting polymers for the detection of various analytes. His efforts aim to harness sunlight to create chemical fuels, particularly through the development of photoelectrochemical cells. Throughout his career, he has been involved in the education of students in chemistry, offering courses that blend theory and practical application on semiconductor technologies. His ongoing research interests include optical and electronic properties of semiconductors, water oxidation, and hydrogen evolution catalysis, among others.
Most Caltech graduate programs are PhD-only. GRE General and Subject tests vary by department; many have made them optional or no longer accept them.
