About Me

I am an M.Sc. student in Data Science and Artificial Intelligence (DSAI) at Saarland University, Germany. I am currently a Student Research Assistant in the Trustworthy ML group at CISPA Helmholtz Center for Information Security, in the group of Prof. Dr. Mario Fritz. I was a Research Fellow at the AI Safety Saarland Incubator and a Student Research Assistant at DFKI in the Interactive Machine Learning group.

My work lies at the intersection of A(G)I Safety and Human-AI Interaction — with a particular focus on evaluating model safety for user welfare, identifying hidden biases, and understanding how language models can be adapted through multi-turn interactions and memory.

Research Interests

• A(G)I Safety: evaluating LLM safety for user welfare, identifying failure modes of deployed AI systems
• Personalization via Multi-Turn Interactions: adapting language model behaviour through conversational context
• Personalization from Memory: enabling models to learn and retain user-specific knowledge across interactions

Beyond Research

I am an avid traveller — having explored 15+ countries across the world. Outside of academia, I enjoy staying updated on the latest in tech and culture through X, and I am a big movie buff.

I am also a proud President Scout Awardee, having received the highest scouting honour in India from the Former President of India in December 2016.
