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

Hey there!

I am a PhD student 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 overaching research question centers around how we can control large language models to generate creative output. I specifically focus on the following questions 1) Can LLMs understand/interpret creative language? 2) Can computers generate creative text such as Sarcasm, Simile, Metaphor. 3) Can computers maintain the figurative aspects of language when translating it between language pairs.
Recently I am also interested in Instrution tuning, Continual Learning and Human-AI Collaborative Writing.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 want to work with me , please send me an email. I mentored the following students:

Arkadiy Saakyan (Columbia Undergad)

Aadit Trivedi (Georgia Tech Undergad)

If you are enrolled for Semantic Representations for NLP, here are my office hours:

Fun fact about me :

My first NLP paper has a Syntactic Ambiguity in it
I am a big believer in Computational Creativity and towards this I have worked on publishing papers which makes a computer generate Metaphors Similes, Sarcasm and Stories
