I am a Machine Learning Engineer at Apple.

I have a Masters degree from Language Technologies Institute, Carnegie Mellon University, where I worked with Professor Maarten Sap on LLM safety. I was also co-advised by Professor Tom Hartvigsen on my work at CMU.

During the summer of 2024, I interned at Scale AI with the GenAI and SEAL team, working on multilingual math reasoning and agent safety. Prior to joining CMU, I worked at Samsung Research as a Research Engineer in the OnDevice AI division building upon various ML models for smartwatch and smartphones. I graduated from IIT (ISM) Dhanbad in 2020 as the Silver Medalist of the Computer Science Department.
