Rich's early work at Berkeley focused on the use of resonance Raman and time resolved optical spectroscopy to elucidate the structure and reaction dynamics of energy and information transducing photoactive proteins. Mathies' more recent work in the area of biotechnology and the Human Genome Project has led to the development of new high-speed, high-throughput DNA analysis technologies such as capillary array electrophoresis and energy transfer fluorescent dye labels for DNA sequencing and analysis. Prof. Mathies founded The Center for Analytical Biotechnology. He is author of over 370 publications and 25 patents on photochemistry, photobiology, bioanalytical chemistry and genome analysis technology. Prof. Mathies' office is in 307 Lewis Hall; he may be contacted by phone at (510) 642-3599 or by email.
