I am a new postdoctoral fellow in Prof. Sakhrat Khizroev's group. My main focus of interest is

research, development and diagnostics of new types of hardware for future computers, mainly concerning non-volatile memory and possibly logic elements.

The main area of my past seven years of research was magnetic memory elements, ultra-fast magneto-optic techniques and microfabrication. This includes Time Resolved Scanning Kerr Microscopy (TR-SKM), Photoelastic Modulator (PEM)-based  magnetization diagnostics, fabrication of a novel prototype Hall Effect based MRAM element and experiments on trapping and detection of live magnetotactic bacteria using a micromagnetic trap.

Here in the UCR I continue the study of magnetorecording in collaboration with Nissim Amos, Rabee Ikkawi and Andrei Lavrenov. The goal of our current research is to achieve fast and reliable multilayer information recording to and reading from patterned magnetic medium. I joined the group assembling a powerful PEM-based diagnostic system for high coercivity perpendicular-anisotropy samples
