Karthik Narayan

I am a third year Ph.D. student working with Pieter Abbeel and Jitendra Malik at UC Berkeley. I was funded by the NSF Graduate Fellowship, and am now funded by the NDSEG Fellowship.

I've spent time at Google, Cornell CLASSE, and Amrita University. I received my undergraduate degrees in Computer Science and Discrete Mathematics from Georgia Tech.

This fall, I will be an intern at Citadel LLC's Quantitative Strategies Group.

My research focuses on developing low-cost high-fidelity portable 3D scanners. I have also developed nonlinear dimensionality reduction algorithms to visualize large datasets.

Instructor: Pat Virtue

@Georgia Tech
When I was at Georgia Tech, I was a TA for CS 1332 (Data Structures and Algorithms), CS 2340 (Objects and Design), CS 3510 (Design and Analysis of Algorithms), and CS 4641/7641 (Machine Learning).

@Amrita University
I was also a co-instructor for a masters senior design course focusing on applying 3D RIA development to e-Learning.
