Ameya Daigavane

I'm a Pre-Doctoral Researcher at Google Research India, working with Prateek Jain and Gaurav Aggarwal towards privacy-preserving graph neural networks. I'm broadly interested in developing machine learning models for scientific applications.

I was a Caltech SURF Award recipient in 2019 and won the ACM SIGBED Scholars Award in 2020.

Previously, I was an intern with the MLIA group at NASA Jet Propulsion Laboratory, where I worked with Kiri Wagstaff and Gary Doran on time-series algorithms to improve the responsiveness of the Plasma Instrument for Magnetic Sounding on the upcoming Europa Clipper mission.

I graduated with a B.Tech in Computer Science and Engineering (with a minor in Mathematics!) from the Indian Institute of Technology, Guwahati in 2020.

Much of my code is open-source: I've especially contributed to TensorFlow Datasets and Flax.

I've also spent time as a volunteer at Youth4Jobs Shine where I mentored differently-abled youth on career planning and employment tips, and at English On Call where I taught English to non-native speakers.
