Research Interests
My research interests are in the field of condensed matter theory. In recent years I have focussed my work to electronic transport in quantum dot systems and nuclear spin dynamics in low dimensional systems. I have also been involved in projects related to superconductivity, diagrammatic solutions for Bose systems, quantum phase transitions, and collective excitations in spin polarized low dimensional systems. In general I am interested in analytical approximations, although my work involves also numerical calculations.
My recent work was supported by Research Corporation and several internal grants from CSUF.
I am always looking to involve undergraduate and graduate students in my research. If you would like to learn more about condensed matter physics , please contact me or stop by my office.
Teaching Interests
In recent years, I have enjoyed teaching a wide variety of lower- and upper-division physics courses, as well as graduate courses. Although I greatly enjoy teaching introductory physics, my main teaching interests are with advanced theory courses including quantum and statistical mechanics, and solid state.
