I am a final year Undergraduate student of Computer Science and Engineering at Indian Institute of Technology, Delhi. Life here is really exciting- working on new things, exploring new topics, and hearing new ideas every day.

On the whole, I love to code and am an enthusiastic coder. In general, I am highly enthusiastic about learning new things and trying out new ideas. My hobbies include robotics, competitive coding and chess. I am also an avid reader. I actively participate in sports, and run and swim to keep fit. I love to listen to western classical music . I also enjoy watching movies and TV series. I absolutely adore good food (which is sadly not very abundant here at IITD).

I am interested in artificial intelligence and machine learning in general, and deep learning in particular. I am currently working with Prof. Mausam as part of the Data Analytics and Research Group (DAIR), IIT Delhi, on developing deep algorithms for planning. As of now, I am excited about deep reinforcement learning, meta learning, few shot learning, concept learning and lifelong learning. I am also greatly interested on the application side of AI, specifically in robotics and automation. The projects I have undertaken and the activities I have participated in reflect my varied interests.
