I am a second-year PhD student in Computation, Cognition, and Language (NLP) at Language Technology Lab, University of Cambridge. I am supervised by Prof. Anna Korhonen and Dr. Ivan Vulić. I am also a Student Researcher at Google Cloud AI Research. Previously, I interned at Gemini (RADML) and CAIR Teams at Google DeepMind (formerly 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, UCL NLP Lab. I graduated top of my class.

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