  • About Me

    Hello! I am a full-time research assistant at the Ubiquitous Knowledge Processing (UKP) Lab at the Technical University of Darmstadt. I have been fortunate to be supervised by Prof. Dr. Iryna Gurevych and mentored by Dr. Nils Reimers. My primary research interests lie in the area of Natural Language Processing and Information Retrieval. My long-term research ambition lies in improving low-resource and data-scarce NLP, a practical setting useful for both research and industry.

    Prior to UKP, I worked as a Data Scientist in the Industry for a year. I graduated with B.E. (Hons.) in Electronics and Instrumentation from Birla Institute of Technology and Science (BITS) Pilani, India. Personally, I love football and I'm a passionate Chelsea FC supporter. I love to cook and travel unknown beauties. I am impulsive and I like impromptu hikes, bike trips, or treks in nature.

    I am currently exploring Research Oppertunities (PhD) in Natural Language Processing (NLP) around USA, UK or Europe. If you find my profile relevant, feel free to contact me on any of my social handles mentioned below or leave me a message here. I speak English, Hindi and Bengali fluently. I am learning German (A2).
