About

I am a full-time Ph.D. scholar in the Department of Computer Science at IIIT-Delhi. I am fortunate to work under the supervision of Prof. Anubha Gupta. I am part of the SBILab at IIIT-Delhi. My work lies at the intersection of Speech processing, Natural Language Processing (NLP), and Human-Computer Interaction (HCI). My research focuses on developing robust, cost-efficient, and inclusive speech technologies, with a particular emphasis on low-resource languages. I was recently honored with the Outstanding Paper Award at ACL 2025 (Core A*) for my paper IndicSynth, which presents a large-scale synthetic speech dataset for low-resource Indian languages. Before joining the Ph.D. program in August 2019, I worked as a Teaching Fellow in the Department of Computer Science at IIITD between August 2018 and July 2019. With experience in both research and teaching, I am passionate about mentoring students and fostering collaborations. I am currently seeking faculty opportunities where I can contribute to cutting-edge research and impactful teaching in speech and language processing.

Research Interests:
  • Speech and Language Processing
  • Low-Resource Speech Processing
  • Cost-Efficient Speech Processing
  • Ethics, Bias, and Fairness in Speech Processing
  • Multilingual and Cross-Lingual Speech Processing
  • Generalizable and Inclusive Speech Processing
