various theoretical methods to address a wide range of issues, from the
origin of disease in the human body to the electronic wavefunction in
crystals. In collaboration with biochemistry, we use electronic cluster
calculations to study the cis and trans conformations of peroxynitrite
and protonated peroxynitrate because the decomposition of the latter
to the type of tissue damage associated with nerve disorders such as
Gehrig's disease. Also, we are performing numerical simulations
finite elements to test the effect of RF heating in magnetic resonance
imaging at 4.1
T.In another area, we are implementing a density-functional theory
of positron bound states in electronic systems to study lifetime shifts
related to crystal-field effects in systems involving point defects in
with Dr. Yogesh Vohra, we simulate the complex hydrocarbon chemistry
kinetics in low-pressure diamond CVD. In particular we see the role of
small amounts of O2 in increasing the CH3/C2H2 ratio, an indicator of
rather than graphitic growth.

Dr. S. C. Ke, we simulated protein crystal growth using
a stochastic model. The simulation showed that the use of larger
units in the growth yielded results in closer agreement with
