About me

I am a Senior Staff Research Scientist at DeepMind. I currently work on training LLMs as part of Gemini.

Before joining DeepMind as a Research Engineer in 2016, I was a Software Engineer at Google Zurich working on NLP using neural networks.

Education

I obtained my PhD at UCL, supervised by Prof. Marc Deisenroth. I passed my viva without corrections in May 2023. My examination committee was formed by Dr. Ferenc Huszár and Dr. Patrick Rebeschini. You can find my PhD thesis here.

I finished my 4 year Computing MEng degree from Imperial College London in 2014, with first honours and a prize of excellence for an outstanding overall performance.

Professional Interests

Generative models, reinforcement learning, natural language processing, scalable and safe machine learning.

I am currently focused on understanding optimisation in deep learning.
