Dwijen Chawra

I'm a Computer Science graduate from Purdue University. My interests lie in robotics, ML, and high performance computing.

What I'm up to

Currently working as a Robot Software Engineer at Rhoda AI in Mountain View.

Previously, I worked on Helix at Figure and helped architect a robotics lab at Labelbox collecting data for foundation models.

At Purdue, I worked on scaling LLM training on supercomputers with eLab and represented the MARS Lab at the WBCD competition at ICRA 2025, where our team placed third.

I've also interned at Amazon Web Services on the Amazon Quick Suite core engineering team and at Arta Finance, and worked as an undergraduate researcher at Stanford's Zeitzer Circadian Research Lab.

Gesture interactions with a computer through user-trained hand gestures with only a webcam. Sub-second latency for action recognition, and scales to infinite gestures.

Drug Identification with NER Models

Project Page | GitHub | Aug 2022 - May 2023

Worked with Battelle Inc. to develop a NER model to identify drug name and usage from medical records, utilizing a BioBERT bi-directional LSTM model to achieve 94% accuracy on the test set.

Soundscape
