Sriram Somasundaram

I am a M.S. candidate in the Computer Science department at Stanford University. I'm working at the Stanford Vision Lab in the People, AI, and Robots group and am advised by Prof. Fei-Fei Li. Previously, I was an undergraduate researcher at USC's Cognitive Learning for Vision and Robotics Lab and was advised by Prof. Joseph J. Lim. My research interests are reinforcement learning, robotics, and machine learning.

In 2015, I was a research intern at the Mellins Lab at Stanford University under Prof. Elizabeth Mellins. I've also interned at Riot Games, Raytheon, and Quid.

I'm interested in investigating how learning algorithms can enable machines to acquire complex skills in real-world settings. My research experiences thus far delve into learning and interpreting deep representations for complex skills and enabling machines to smoothly compose and execute skills for hierarchical tasks.

We investigate the autoimmune contribution to narcolepsy development and analyze the in vivo expansion of HCRT-reactive TRAJ24+ cells.

pH-susceptibility of HLA-DO tunes DO/DM ratios to regulate HLA-DM catalytic activity
Wei Jiang, Michael J. Strohman, Sriram Somasundaram, Sashi Ayyangar, Tieying Hou, Nan Wang, Elizabeth D. Mellins,
Scientific Reports vol. 5, p. 17333, Nov. 2015

We investigated the pH-dependence of DM-DO-mediated class II peptide exchange and identified an MHC-II allele-independent relationship between pH, DO/DM ratio, and efficient peptide exchange.

Voice Conversion between Male and Female Speech
Sriram Somasundaram, Andrew Szot, Md Nasir, Arshdeep Singh, 2017
blog post

Investigated voice conversion between male and female audio using multiple approaches including a CycleGAN on audio spectrograms and speaker conditioned generators with and without latent space supervision.
