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 broadly interested in graphs and machine learning. Currently, I focus on non parametric, neighborhood algorithms for understanding data and deep learning models.

Prior to joing 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.
