Diego Martinez Taboada

About Me

I am a fourth-year PhD student in the Department of Statistics and Data Science at Carnegie Mellon University, where I am advised by Prof. Aaditya Ramdas. Previously, I completed an MSc in Statistical Science at the University of Oxford and a bachelor's degree in mathematics at the University of Santiago de Compostela.

Research

I am broadly interested in the theory and application of methodologies built on high-dimensional (and even infinite-dimensional!) spaces. In particular, I have recently been focusing on (the intersection of) vector and operator-valued concentration inequalities, sequential statistics, causal inference, and RKHS theory (kernel methods), among others.
