EXPERTISE AND RESEARCH INTERESTS

 

            My background is in the Electronic Structure Theory and Computational Materials Science. I am mostly interested in solving complex cross-disciplinary problems by developing and using the electronic structure theory methods.  I am interested in novel materials, complex framework oxides such as zeolites, high dielectrics constant materials i.e. transitional metal oxides including perovskites. I have investigated the physics and chemistry of the  semiconductor-insulator interface, and semiconductor surfaces including chemical reactions at the surface. Most recently I have started working on the physics of nano-scale devices and conduction mechanisms in molecular systems.

SUPERVISION OF STUDENTS AND POSTDOCS

 

I served on the Doctoral Committee of Mr. E. Chagarov in the Science and Engineering of Materials Program at Arizona State University (Ph.D., November, 2003). I served as a co-chair (with Professor Ch. Ringhofer) on the Doctoral committee of Mrs. H. Loechelt in the Department of Mathematics at Arizona State University (Graduated with Masters in 2001 due to family circumstances). I often worked with summer interns at Motorola, and interacted with several students through SRC. One of my former summer interns Xiaodong Zhang of Ohio University joined my group at Motorola as a postdoc, and has later been promoted to a staff member, he is now at  the University of Texas M.D. Anderesen Cancer Research Center in Houston, TX.
