Dan Pinkel received his Β A degree in physics from the University of Michi gan, and MS and PhD degrees in solid-state physics from the Universi ty of California at San Diego. After a postdoc at UCLA in medical physics, where he first came into contact with flow cytometry, he went to his present position in the Cytophysics Section of the Biomedical Sciences Division at Lawrence Livermore Na tional Laboratory. Current research interests include instrumentation de velopment and high-precision mea surements on mammalian sperm.
