About me
I am a PhD student in Statistics at the School of Mathematics, University of Edinburgh, supervised by Víctor Elvira. Previously I studied physics at the University of Crete and mathematics at Washington State University
My research interests are in developping robust and efficient Bayesian inference algorithms for complex dynamical systems and signal processing. My PhD work is focused on Bayesian filtering and smoothing of state-space models.
