B. S. in Chemistry (1987).

Professional Career

1997-present
Assistant professor of Chemistry, National and Capodistrian University of Athens
1996-1997 Postdoctoral Research
Advisor: Dr. J. P. Cowin, Pacific Northwest National Laboratory.
Project: Ion-surface reaction dynamics of thin films.
Ion mobility in thin films of hexane and water grown on Pt and the dielectric properties of these substrates are studied as a function of sample history and temperature by monitoring surface voltages with an oscillating electrode (Kelvin probe).

1992-1996 Postdoctoral Research
Advisor: Prof. S. T. Ceyer, Massachusetts Institute of Technology.
Project: Gas-surface reaction dynamics of fluorine and xenon difluoride on a silicon crystal.
The etching reactions of Si by F2 were studied using an ultra-high vacuum scattering machine equipped with a rotatable mass spectrometer. A new reaction mechanism was observed and Si etching with fast F2 beams was demonstrated. Similar studies of Si etching with XeF2 revealed the ejection of fast XeF and very fast F fragments during the early stages of the reaction.

1987-1992 Doctoral Research
Advisor: Prof. R. N. Zare, Stanford University
Project: Reaction dynamics of the reaction Ba + HI -> BaI + H.
Product rotational distributions were determined by laser induced fluorescence and combined with reagent relative velocity data to provide information on the impact parameter of the reagents that yielded product molecules in specific vibrational states. Studies were done under crossed beam and beam - gas conditions.

1983-1986 Undergraduate Research
Advisor: Prof. C. E. Efstathiou, National University of Athens
Project: Developed hardware and software to interface titration and stripping voltammetry equipment to microcomputer.

Advisor: Prof. P. Macheras, National University of Athens
Project: Worked on an educational computer program presenting the concept of bioavailability of drugs.
