Welcome

I am an Assistant Professor in the Department of Physics at Miami University Oxford, OH. I received my Ph.D. from Southern Illinois University, Carbondale, IL. My BSc and MS were from the same university.

Research Interest

My research is centered on novel magnetic materials (broadly defined) that exhibit multifunctional properties. I am interested in the synthesis of these materials mainly by arc melting and high temperature annealing and sintering techniques. The properties of the materials are explored by several characterization techniques including x-ray diffraction, magnetization, magneto-transport and several other techniques. The properties that I am particularly interested in include, but not limited to, the following:

Coupled and decoupled Magnetic and structural transitions
Magnetocaloric effects
Magnetoresistance
Exchange bias effects
Permanent magnetic materials

Opportunities for Students

Students at both Undergraduate and Masters level are always welcome to participate in the research in my lab. In my research group the students will be provided with an opportunity of gaining extensinve experimental research experience in magnetism. From sample preperation to characterization, students will learn different experimental techniques. If you are interested, send me an email or stop by my office sometime to discuss possible research oppportunites.
