Hi! I'm a member of the technical staff at Anthropic. Previously, I was a Senior Research Scientist at Toyota Research Institute, building generative models for text and videos, with a focus on improving training efficiency and dataset quality.
Prior to this, I was an Applied Scientist at Amazon, and a Ph.D. student at Carnegie Mellon University advised by Prof. Deva Ramanan, working on open-world object detection and tracking.
Email: achal@anthropic.com, achalddave@gmail.com
Most of my projects can be found on my Github.
