Research Interests:

I am an experimentalist in condensed matter physics. My main research interest is to study highly correlated electronic systems such as high temperature superconductors, ferroelectrics, magnets etc. We receive samples from University of Connecticut and Taiwan National Institute and study them using a wide range of experimental probes. Starting from La2-xSrxCuO4 as-grown samples, we produce superconductors in our laboratories using wet chemical techniques. The process involves intercalation of excess oxygen into LSCO samples. Once the samples are oxidized, we do characterization studies at other facilities using different probes. Preliminary studies on superconductivity and magnetism are done at UConn facilities using X-ray and Superconducting Quantum Interference Device (SQUID). In order to study the intrinsic magnetic properties we use Muon Spin Rotation (SR) probe and the samples are sent to Paul Scherer Institute (PSI) in Switzerland. Neutron scattering to measure the long-range magnetic properties and these are conducted at different locations (Denmark, Switzerland and USA). 

My secondary research interest is studying thin films using Atomic Force Microscope (AFM). We obtain our film samples from the University of New Haven. Currently we are studying nano particles using the AFM. In the recent years AFM has emerged as a perfect probe to study nanoscale properties in a wide range of systems. Currently our research focuses on nano particles that can be used in drug delivery.  We hope to expand our research and collaborate with bio-medical and biology researchers in the university.


In addition to my scientific focus in research, I am also intersected in pedagogical research. When I was teaching introductory level physics courses I incorporated some of the pedagogical tools I developed in the recent years. Some of them are, Wikispaces (Wikis), Collaborative Group Problem Solving techniques (CGPS), the combination of Just in Time Teaching (JiTT) and Wikispaces (Wikis). In these methods, the students are encouraged to think outside of what is taught in the classroom, while developing their own critical thinking abilities.
