I am a 4th year CDT student in the Department of Statistics under the supervision of Prof. Theo DamoulasLink opens in a new window and a member of the Warwick Machine Learning GroupLink opens in a new window. My research focuses on robust Bayesian inference, model misspecification and distributionally robust optimisation.

Prior to starting my PhD, I completed an MSc in Computational Statistics and Machine Learning at UCL and a BSc in Mathematics at Warwick.

My official name is Charita which is pronounced 'Harita' so I go by the latter.
