01 / ABOUT
I am an academician and researcher in Computer Science and Engineering, currently serving as an Assistant Professor (Senior Scale) at the School of Computer Science, UPES, Dehradun.
I completed my Ph.D. in Computer Science and Engineering at the National Institute of Technology Silchar. My academic work spans natural language processing, neural machine translation, multilingual & muiltimodal systems, deep learning, LLM and language-resource development.
I am interested in research that makes NLP technologies more effective for languages and communities that are underrepresented in digital resources.
