My first home computer was a Macintosh 128k. My most recent computer is a Mac Pro7.1, and currently (September, 2021) I also use a 16" MacBookPro11.3, Late 2014 Mac mini and iPhone. Earlier I had learned to program in FORTRAN IV using punchcards on a CDC6400. By formal training I am mostly a biologist, with expertise in biological, physical, analytical chemistry.

Retired since 1998.
