Teaching Interests

 Any method that increases student engagement in my classes and labs. I'm mesmerized by tutorials, clicker questions, the use of mini-lectures by students, and class-wide discussions to supplement chalk board lectures and enhance the learning going on in my class room.

Research Interests

 Magnetic, optical and electrical properties of materials, magneto-elastic properties, magneto-plastic properties, measurement techniques, adaptive optics, materials properties of transition metal oxides and properties of transition metal oxide - silicon heterojunction devices, magnetic anisotropy in permalloy thin films.
