I am a second-year PhD student in Computation, Cognition, and Language (NLP) at Language and Technology Lab, University of Cambridge. I am supervised by Dr Ivan Vulic and Prof Anna Korhonen. I am also a student researcher at Google Research.

Before starting my PhD, I was an undergraduate student reading Engineering Science at University of Oxford. I received my second Master degree in MSc Machine Learning, University College London. I graduated top of my class.

I am always interested in modular, efficient, and reward-driven responsible intelligence.
