Meng Fang

I am an Assistant Professor in AI at University of Liverpool. I'm also a visiting (assistant) professor at Eindhoven University of Technology (TU/e). I received my Ph.D. from University of Technology Sydney, advised by Prof. Dacheng Tao, and then worked as a postdoc with Prof. Trevor Cohn at the University of Melbourne NLP group. I had been a research scientist / intern at Tencent Robotics X / AI, CSIRO and Microsoft Research Asia before.

My research focuses on auto agents or systems capable of human-like language understanding, reasoning, and decision-making. My main areas include NLP and RL.

Research

Projects
	Text-based games TL;DR: We consider language understanding and reasoning for agents in text-based games. Keywords: responsible AI, knowledge graphs, attention, RL, hierarchical RL. [project page]
	Conversational AI TL;DR: We consider chatbots for dialogue generation and reasoning. Keywords: Language generation, persona. [project page]
	Question & Answering TL;DR: We consider the reasoning process for question and answering problems. Keywords: Retrieval-augmented generation, open domain, knowledge graphs, graph neural networks [project page]
	Reinforcement learning TL;DR: We propose new agents and environments for robotics and Game AI. Keywords: sparse/delayed rewards, sample efficient, multi-goal RL, continual learning. [project page]
