**Tuhin Chakrabarty**
Ph.D. Student in CS @ Columbia

Hey there!

I am a PhD candidate in Computer Science at Columbia University. Within the department I am a part of the Natural Language Processing group , where I am advised by Smaranda Muresan.My research is supported by the Columbia Center of Artifical Intelligence & Technology (CAIT) & Amazon Science Ph.D. Fellowship. I also work with Violet Peng at UCLA PLUS Lab and He He at NYU ML² .My research interests are broadly in Natural Language Processing and Machine Learning, with special focus in Computational Creativity.My overarching research question centers around how we can use large language models for creativity.I specifically focus on the following questions

1) Can LLMs understand and explain/interpret creative language? (EMNLP 2022, TACL 2022)
2) Can LLMs generate creative text such as Sarcasm, Simile, Metaphor, Stories? (ACL 2020, EMNLP 2020, NAACL 2021)
3) Can LLMs maintain semantic faithfulness when translating creative text? (EMNLP 2021).
4) Can LLMs keep learning tasks requiring creativity without forgetting knowledge about the general NLP tasks (EMNLP 2022)
5) Can humans effectively collaborate with LLMs to produce creative content. (EMNLP 2022)
6) Can LLM's be helpful in aiding Vision and Language Models for creative tasks at hand (Under Submission)

Prior to joining Grad school I was an engineer at UBER.For more information about me, see my CV or contact me.

My introduction to NLP was through my friend Chris Hidey who mentored me and helped me write several papers. As an act of giving back to the community, I am happy to advise undergrads and master students about grad school applications and/or how to get involved in NLP research. If you are at Columbia and have experience with Reinforcement Learning or Vision and Language and want to work with me , please send me an email. Before you email me please make sure we have overlapping research interests I mentored the following students:
