Currently developing software for encryption, authentication and commerce over the Internet; especially dealing with credit card transactions, mortgage loan applications, and privacy enhanced mail.

Visiting Physics Scholar, Ohio State University
Installed and maintained several networked computers, on OS/2 Linux, Sun and Vax platforms. Data analysis for an atomic scattering experiment on IBM-PC, Mac, VAX, and Sun computers. Assisted in ongoing experiments on excitations in superfluid 4He at 40 mK. Assisted in installation of an Oxford dilution refrigerator.

Post-Doctoral Physics Research, Pennsylvania State University
Designed, built and performed experiments for varietal precision heat capacity measurements of 4He films on Vycor, aerogel, and graphite substrates at temperatures from 5 mK to 1 K. wetting studies of 4He on cesium surfaces near the lambda point. Assisted in torsional oscillator experiments of the superfluid fraction of 4He in porous glasses.

Graduate Research Associate, Ohio State University
