About

Hi, I’m Sarath, a Ph.D. candidate in Ming Hsieh Department of Electrical and Computer Engineering at University of Southern California. My research advisor is Prof. Antonio Ortega.

I’m interested in graphs and machine learning. Currently, I focus on non-parametric, neighborhood algorithms for understanding data and deep learning models. Read about one research direction I’m currently pursuing here.

I’m in the job market for a postodoctoral/research position. Please send me an email if you think I’ll be a good fit - I would be happy to discuss my research and aspirations.

Background

Prior to joining USC for my PhD, I worked as a software engineer for 2.5 years at KLA-Tencor’s Wafer Inspection Division on a defect classification software.

I obtained my Masters degree with specialization in computer vision and machine learning from USC. During my study, I had the opportunity to work as part of the computer vision research group at USC Institute for Robotics and Intelligent Systems where I was advised by Dr. Jongmoo Choi under the guidance of Prof. Gerard Medioni. I was also a part time software developer at Laboratory of Neurological Imaging where I worked on project Informatics Visualization in NeuroImaging (INVIZIAN) lead by Prof. John Van Horn.

I completed my Bachelors degree in Electronics and Communication from National Institute of Technology - Tiruchrappalli, where I worked under the advise of Profs. Deivalakshmi and Palanisamy.
