Department of Pure Mathematics and Mathematical Statistics

I am a postdoctoral research associate in Statistics, supervised by Professor Richard J. Samworth.

My research interests include shape-constrained density estimation and regression, as well as the statistical analysis of approximate message passing (AMP) algorithms.

Education

2017–2021: PhD in Statistics, University of Cambridge, supervised by Prof Richard J. Samworth. Thesis: Topics in shape-constrained inference.

2013–2017: BA and MMath, Trinity College, University of Cambridge.

Publications and preprints

Feng, O. Y., Guntuboyina, A., Kim, A. K. H. and Samworth, R. J. (2021). Adaptation in multivariate log-concave density estimation. Ann. Statist., 49, 129–153.

Teaching and other activities

I have supervised the following courses: Part IB Linear Algebra, Statistics and Optimisation; Part II Mathematics of Machine Learning, Principles of Statistics, and Probability and Measure. I also gave the examples classes for Part III Topics in Statistical Theory (2020-21).

I am a member of the Statistics Clinic team.
