I am currently a Research Engineer (on contract) at Google Research India, working with Dr. Partha Talukdar in the NLU Group. Here, I am working on entity-aware translation of educational videos to create subtitles for a host of Indian languages.

Before this, I spent an amazing year at Microsoft Research India, and worked with Dr. Monojit Choudhury and Dr. Kalika Bali on various problems in low-resource language systems and probing NLI models.

I did my undergraduate thesis at Microsoft Research under Navin Goyal and Monojit Choudhury, on semantic parsing applied to the conversion of natural language to regular expressions and SQL. I graduated with a B.E. (Hons.) in Computer Science from BITS Pilani, Goa, India, in 2019.

Research Engineer | Manager: Dr. Partha Talukdar

-- Creating a scalable entity-aware translation+transliteration pipeline to generate subtitles for English-medium college lecture videos (from NPTEL) for various Indian languages.

Microsoft Research India
Aug 2019 - Aug 2020

Research Intern | Managers: Dr. Kalika Bali, Dr. Monojit Choudhury

-- Probed large pretrained lanuage models for NLI reasoning, by designing a taxonomy of reasoning capabilities, annotating an existing NLI dataset based on the capabilities, then evaluating the model performance on this new dataset.
-- Worked on a range of multilingual problems, such as quantitative analysis of language diversity in ACL, efficacy of code-mixing chatbots, measuring quality of crowdsourced speech data, among others.
-- Works published at ACL, CoNLL, CSCW, LREC, EMNLP Workshop, and ICON (see publications below).

Microsoft Research India
Jul 2018 - Dec 2018

Research Intern | Managers: Dr. Navin Goyal, Dr. Monojit Choudhury

-- Worked on semantic parsing and its applications to natural language to code. Particularly focused on natural language to regular expressions (NL2Regex), and to SQL queries. Implemented and experimented with different neural architectures for NL2Regex, and conducted an error analysis. Subsequently, I also analyzed quality of various semantic parsing datasets using a range of metrics and indicators.
-- Research carried out also contributed to my undergraduate thesis.

White Data Systems India (i-Loads), Chennai, India
May 2017 - Jul 2017

Software Engineering Intern | Manager: Mr. Gokulan Jayaram

-- Created voice interface application for truck drivers. Used pocketsphinx-android from CMUSphinx to power voice recognition. Customized to recognize key commands in English, Hindi, and Indian-English.
-- Created capabilities like an in-built support system, location and route support, and verbal data entry.
-- Presented prototype to I-Loads administration (CEO,CFO,CTO) and tech team.
