Bio and Interests: 
I received my PhD in physics from the University of California in 2009 studying the magnetization reversal mechanisms of a variety of different types of magnetic nanostructures. After-which I joined the group of Prof. Johan Åkerman at the University of Gothenburg in Sweden as a postdoctoral fellow in order to pursue studies in spin transfer torque, in particular spin torque oscillators._x000D_ _x000D_ My research interests include: Fabrication and experimental characterization of the structural, magnetic, and transport properties of a variety of nanoscale magnetic materials. More specifically, magnetization reversal and hysteresis, magnetoresistance, interlayer coupling, exchange bias, and spin-transfer torque. Expertise in sputter deposition, e-beam evaporation, electrodeposition, photo- and e-beam lithography, x-ray reflectivity and diffraction, SQUID, alternating gradient and vibrating sample magnetometry, magneto-optical Kerr effect, magnetic force microscopy, and high frequency measurements.
