I am a second year MLT (Master's in Language Technologies) student in the Language Technologies Institute, School of Computer Science at Carnegie Mellon University, co-advised by Alan W Black, Yulia Tsvetkov and Alex Rudnicky. I'm also a member of Tsvetshop.

My research focuses on developing algorithms for machine learning and applying my methods in order to study how machines can mimic humans in congitive tasks, especially those related to Language. My research with Alan and Yulia focused on negotiation and persuasion in dialogue systems where we are trying to understand the qualities of good/bad sellers/persuaders and including explicit strategy sequence information to build a system that can negotiate better. With Alex, I worked with CMU's team, Tartan, on the Amazon Alexa Challenge, 2020 and we managed to reach the semi-finals. I also studyed coherence in dialogue and the right questions to ask for better engagement, by using external knowledge to augment the models.

Right now, my focus is on low resource NLP and exploring knowledge proliferation. We are exploring adapter based approaches for multilingual summarization. I'm also working on understanding and profiling important concepts in academic publications, which can later be used to study evolution of science.

Before I joined CMU, I worked in Samsung Research Institute, Bangalore, India where I was working in the Voice Intelligence Team on dialogue systems and chat-bots. Before that, I spent a wonderful semester working with Partha Talukdar at Machine and Language Learning (MALL) Lab in the Indian Institute of Science, Bangalore. I graduated with a B.Eng. in Computer Science from Birla Institute of Technology and Science, Pilani, India. In my Bachelor's thesis, I worked on incorporating external knowledge in distantly supervised neural relation extraction methods as part of iNELL (which is based on NELL).
