Distinguished Service Award, Research & Development Engineering Center, US Army 1993
1999 Billy and Claude Hocott Distinguished Centennial engineering Research Award.

Focus:
For a number of years, research has neen done on atmospheric aerosols as air pollutants, and also on aerosols with a view toward their technical applications, including creation of aerosol jets for etching semiconductor devices, and for surface cleaning of semicon devices. Work is currently underway on synthesis of nanoparticles.


In the study of high volume production of nanometer particles, particle ablation is examined

Research:
Current research is focused on synthesis and applications of nanoparticles (particles with diameters of the order of 5 nm or less); this work is sponsored by NSF under their GOALI program, that involves collaboration with the Electronics Division of duPont Corporation. Work has also been carried out on use of finite element techniques for solving Maxwell's equations for scattering and absorption of light by small particles for systems that are analytically intractable. We have demonstrated feasibility of obtaining the morphology-dependent resonances (MDRs) of spherical particles where analytical solutions are not possible.
