Position: Research Professor, Physics

Educational Background: B.S. 1962, Kabul University, Kabul, Afghanistan, M.S. 1968 Ph.D 1973, Moscow State University, Moscow, Old Soviet Union

Research Interests:   Experimental Optical Physics, Linear and Nonlinear Laser Spectroscopy including Laser Raman Spectroscopy.

I am an experimental optical physicist with over 10 years experience in solar-pumped gas laser at NASA-Langley Research Center (NASA-LaRC), which is about 10 miles from Hampton University. My area of research includes atomic and molecular spectroscopy, and laser optics. I developed several optical diagnostic techniques such as electron beam fluorescence (EBF), and laser-induced fluorescence (LIF) at Hampton University and applied these techniques in Hyper Flow Generator (HFG) at NASA Langley Research Center.

Currently I am involving in linear and nonlinear ultrafast laser spectroscopy of nanomaterials under the CREST Center for Laser Science and Spectroscopy (CLaSS) at Hampton University.

Our research activities in the applied nanoscience and nanotechnology include optical dynamics of surface Plasmon resonance, surface-enhanced Raman scattering (SERS), and ultrafast nonlinear optical spectroscopy of nanoscale materials for photonic and medical applications.

A rapid, sensitive, selective, and quantitative spectroscopic assay for cancer screening and drug level analysis is one of the most encouraging, challenging, and innovative forms of immunoassay and treatment for enhancing human health. More recently, we employed the SERS technique to identify the selectivity, quantification, and limitation of detection of gold-nanoparticle-assisted immunoassay and therapeutic spectroscopy on cancer markers and as well as drug identification for cardiovascular problems.

I have teaching experiences over 35 years. I have been taught different graduate and undergraduate core courses and elective courses. The students, both graduate and undergraduate, in our research group publish articles in refereed journals and present papers at the regional, national, and international conferences.
