About Me

I currently work as a Senior Applied Scientist in the AWS Bedrock team in Amazon. I work towards bringing state-of-the-art NLP research into life by building models that uncover valuable insights and connections in text.

I previously worked as an Applied Scientist in the NLP Research team at Zalando SE. I designed and built NLP solutions to understand textual feedbacks from millions of Zalando customers.

Earlier, I graduated with a Ph.D. in Computer Science under the guidance of A/P. Min-Yen Kan. My research interests are in the intersection of Natural Language Processing and Information Retrieval. My thesis is formally titled “Automatically Facilitating Discussion in Online Forums”. Towards this, I have worked on many prevailing challenges that hamper the user participation in these forums such as Reddit, HealthBoards, MOOC discussion forums to name a few. I have focused on some key issues such as recommending the suitable discussion threads for interested users through textual content modeling. I have used traditional models such as probabilistic graphical models, as well as recent advancements in NLP through deep learning such as Gated Recurrent Units (GRU), attention mechanism. I have worked on a few important aspects of recommendation systems such as explainability of such systems, and cold-start problem. You can find my CV here.

I have been a part of ALSET NUS, and built an AI based career guidance system. The system recommends online courses for Singaporeans based on their profile. Check out the project details here.

Earlier, I graduated from IIT Bombay in Computer Science and Engineering. As part of my master's thesis, I worked in the area of Cloud Computing and Virtualization under the co-supervision of Prof Umesh Bellur, and A/P. Purushottam Kulkarni.
