About Me

I am currently an Assistant Professor in the NLP group at IT University, Copenhagen. My research interests include improving large language models (LLMs), particularly multilingual ones, and integrating LLMs with symbolic systems.

Previously, I was a Research Scientist at A*STAR, Singapore. Before joining A*STAR, I worked as a PostDoc with Prof. Mark Steedman and completed my PhD under the supervision of Prof. Mirella Lapata at the Informatics Institute of the University of Edinburgh.

My PhD research focused on Natural Language Generation, specifically data-to-text generation. I developed techniques for generating long documents (over 200 tokens) from statistical tables as input. My thesis, titled “Data-to-text Generation with Neural Planning”, explored novel strategies for neural content planning in long-document generation. My thesis received the Best Dissertation in Scotland award from SICSA Scotland. During my PhD, I also interned with the Summarization team at Google Research, London.

Before my PhD, I held several research positions, including:

• Research Assistant with Prof. Yue Zhang at the NLP lab of SUTD, Singapore.
• Research Engineer at the NLP lab of IIT Bombay, working with Prof. Pushpak Bhattacharyya.
• Technical Architect in the research division of a software product firm.

I completed my MS in Computer Science by Research at IIIT Hyderabad under the guidance of Prof. Manish Shrivastava in February 2017. My thesis focused on “Transition-based Techniques for Syntactic Linearization and Deep Input Linearization.”
