About Me

I am working as Solution Architect & LLM Community Manager at Ai2.

I train LLMs to be less clueless, craft high-quality datasets with a Michelin-star chef precision, and push the boundaries of research. In short, I make LLMs work smarter so we don't have to.

With good programming skills and a knack for innovation, I build models that actually do their job efficiently and (mostly) without complaints.

I'm all about adventure whether it's exploring new places, experimenting in the kitchen, playing sports, writing, or getting lost in movies.

Research Interests

Pioneering the fusion of NLP and Generative AI, I strive to solve complex challenges. My research zeroes in on three crucial areas:
1. Multimodal Generation.
2. Dataset Quality, Bias and Fact-Checking.
3. Adversarial Vulnerabilities.
