LLM Research Engineer at Predii and MS by Research student at IIIT Bangalore. I work on multilingual and agentic language models — currently on vision-LLM extraction, retrieval systems, and the mechanistic evaluation of cultural understanding in LLMs.
Experience
Software Development Intern
Spikewell India Pvt. Ltd. · Bhubaneswar, IN
- Built healthcare data pipelines using Gemini 1.5 Pro for medical-grade conversational systems.
- Developed data-ingestion workflows for downstream analytics and ML tasks.

Research
Mechanistic Evaluation of LLMs in Cross-Cultural Scenarios
Ongoing · IIIT Bangalore
- Characterised cultural forgetting across 6 models, 30 cultures and 11 domains over 85K+ dialogues.
- Introduced the Cultural Stability Index (CSI) via linear probing; mean CSI = 0.31 with low-resource cultures showing markedly lower stability.
Cross-Cultural Alignment Evaluation Framework
Ongoing · IIIT Bangalore
- Curating a multilingual, cross-cultural dataset to study linguistic and contextual variation for LLM evaluation.
Principle Alignment in Large Language Models
Ongoing · IIIT Bangalore
- Investigating principle-alignment behaviours and consistency drift in LLMs under varied prompt settings.
