Department of Computer Science and Technology

  • PhD Student

I am a PhD student in the computer Laboratory supervised by Neil Lawrence and Nikolas Nüsken, focusing on topics at the interface of stochastic control and inference.

Biography

- MPhil in Advanced Computer Science (CS Theory + ML Focus) , University of Cambridge, UK.

- BSc Computer Science (Minor in Physics), The University of Edinburgh, UK.

 

Research

Overall the nature of my research is predominantly applied and experimental with a particular interest in data assimilation across the natural sciences. Here are some of the main themes I have recently been interested in learning about / exploring:

- Gaussian Processes

- Filtering in SDEs (Kalman-Bucy Filter)

- Dynamic / Entropic Optimal Transport (Schrodinger Bridges)

- Stochastic Control (HJB Equation)

- Computational Bayesian Inference

- Grey Box models (Semi mechanistic modelling / Data assimilation)

- Signal Processing / Kernel Methods 

- ML approaches to formal langauge generation and verification
