About Me

Welcome to my corner of the internet

Hello! I am a researcher passionate about pushing the boundaries of knowledge. I am a Postdoctoral Research Associate at Oak Ridge National Laboratory working at the intersection of AI for Science & Operations, AI system reliability, and hardware-aware machine learning. My research focuses on building robust, trustworthy, and safety-aware AI systems that can be reliably deployed in mission-critical environments.

I believe in open science, collaborative research, and using technology to make the world a better place. When I am not in the lab, you will find me exploring creative outlets and contributing to the community.
