[PHOTO] Computer Skills

I began my computer programming career in 1979 while I was working on my Ph.D. dissertation in Chemistry, and I needed to fit some non-linear regression models to my data. The TI-59 calculator I started out programming was too limited, so I taught myself FORTRAN and began taking upper-level classes in Computer Science. Two decades later, I have a broad base of computer skills, as summarized below:
