About

I am an AI Research Engineer and NLP researcher working at the intersection of language models, efficient learning, and human-centred AI. As a member of the Lingo Research Group at IIT Gandhinagar, I conducted doctoral research examining how limited annotation effort, training tokens, and examples can be allocated more effectively. My broader interests include instruction tuning, multilingual learning, personalized recommendation systems, retrieval-augmented generation, evaluation, data quality, and human feedback.

Current work

I currently work as an AI Research Engineer at Logituit. My work includes on building production-ready personalization and recommendation systems for OTT platforms, spanning data validation, user profiling, feature stores, vector retrieval, ranking, and recommendation models. My work also explores LLM- and RAG-based personalization, evaluation, automated retraining, and end-to-end production deployment.

Research Interests

My research focuses on developing data-efficient, multilingual, and reliable language models. I am particularly interested in how limited data, computation, and human feedback can be used more effectively when training, adapting, and evaluating AI systems.

• Budget-aware training and data selection Efficient allocation of annotation and training budgets across tasks, examples, and annotators, including the selection of high-value data for language-model adaptation.

• Instruction tuning and multilingual transfer Efficient adaptation of language models through instruction tuning and parameter-efficient methods, with an emphasis on transfer between high- and low-resource languages.

• AI alignment and human feedback Developing reliable and inclusive methods for aligning language models with diverse human preferences while using human feedback efficiently.

• Evaluation, annotation, and data quality Studying how annotation strategies, evaluator diversity, instance difficulty, and dataset quality influence model behaviour and evaluation reliability.

• Retrieval-augmented generation and recommendation systems Combining language models with retrieval, structured knowledge, user behaviour, and content representations to build grounded conversational and recommendation systems.

More broadly, I am interested in building AI systems that are efficient, multilingual, trustworthy, and responsive to the people and contexts in which they are used.

Doctoral Research

My doctoral research at IIT Gandhinagar studied budget-aware decision making for NLP: how to use limited annotation effort, training tokens, and examples more effectively. The broader motivation is that better performance does not always come from simply collecting more data or training for longer; it also depends on deciding where the available resources should be spent.

Read the doctoral thesis.

1. Annotation: I studied the trade-off between collecting more labels for the same example and labeling a larger number of examples. Using a controlled multi-annotator simulation framework, I examined how annotation depth, disagreement, and instance difficulty affect model performance under a fixed annotation budget. The results show that collecting multiple labels is not always beneficial; its value depends on which examples receive additional annotations and how difficult or ambiguous those examples are. This work appeared in EMNLP 2023.

2. Training: I studied how a fixed token budget should be distributed across different task types during instruction tuning. Instead of relying on uniform or dataset-size-based sampling, I developed ADAPT, a validation-driven method that learns task proportions during training. ADAPT treats task allocation as a dynamic decision: it uses validation feedback to shift more of the available training budget toward tasks that are useful for downstream generalization.

3. Selection: I studied how to identify instruction-tuning examples that provide a meaningful instruction-following signal before fine-tuning. I developed Task-Specificity Score (TSS), which measures how strongly an output depends on the given instruction, conditioned on the input. Its extension, TSS++, combines instruction specificity with harder counterfactual instructions and data-quality signals. This allows models to train on smaller but more useful subsets of instruction data.

Together, these projects show that annotation, training, and data selection should be treated as allocation problems rather than simple scaling problems. My thesis develops methods for making these decisions more systematically under realistic resource constraints.

Honorable Mention: Understanding the Model-Hub Ecosystem

Alongside my thesis, I also worked on understanding how machine-learning models are shared, documented, and adopted in public model repositories. In Model Hubs and Beyond, we studied model popularity, performance, and documentation practices on Hugging Face. The work examined around 500 sentiment-analysis models and more than 80,000 human annotations, showing that model popularity is not determined by performance alone and that documentation quality, visibility, and platform-level factors shape which models receive attention and reuse. This project broadened my research from efficient model training to the wider infrastructure and social processes through which models are communicated and adopted.
