Paul Selvin earned a Ph.D. from the University of California, Berkeley, in 1990. Formally it was in physics, but in reality, it was in biophysics. The last experiment for his thesis, for example, was measuring the torsional rigidity of DNA by looking at a fluorophore intercalated in DNA, twisting around. A paper based on this experiment was published in Science (Selvin, 1992, Science) and later confirmed in a single molecule experiment (Bryant, Nature, 2003).
Professor Selvin did two sets of experiments during his postdoctoral training. One was developing a new type of fluorescence resonance energy transfer (FRET) based on lanthanides, called luminescence resonance energy transfer (LRET). He later used this technique to discover how a potassium ion channel, in part responsible for nerve conduction, responds to voltage (Cha, 1999, Nature; Posson, 2005, Nature). The second involved single molecule fluorescence—the first measurement of FRET between a single donor and single acceptor (Ha, 1996, PNAS).
