About me

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 Professor Smaranda Muresan . I also work with Professor Violet Peng and Professor Kathleen McKeown. My research interests are broadly in Natural Language Processing and Machine Learning, with special focus in Creative language generation (both at sentence level and Long Form), Role Of Structured Common sense in Downstream Tasks & Discourse and Argumentation. Prior to joining Grad school I was an engineer at UBER and Amazon.

Research Focus

While I enjoy working on most topics in Natural Language Processing, few of my research interests and directions are:

• Controllable/Creative Language Generation : ACL 2020 , EMNLP 2020( Under Submission)
• Argument Mining & Stylistics in Pretrained Language Model : NAACL 2019 , EMNLP 2019 , EMNLP 2020( Under Submission)
• Fact Extraction and Verification: ACL 2020 , FEVER@EMNLP 2018 , SEMEVAL@2019 ,
• Computational Social Science : ALW@ACL2019

UPDATES

3 Long Papers under submission at EMNLP

I helped building a demo for interactive story generation [Link Here] where given a title a model generates a five sentence short story :) Play with it.

Joining IBM AI Research as a summer 2020 intern where I will be supervised by Avirup Sil working on Question Answering

NON NLP LIFE

When not doing NLP, I love reading.I love Morissey and The Smiths and feel they are the best band in the world :). I also love taking pictures. See my photography trail on my instagram handle (@bonginnyc). I also sometimes write on love and longing Tuhins blog
