Welcome! I am a Professor and the Director of Statistics at the Department of Mathematics and Statistics, Boston University. I am affiliated with the Center for Information and Systems Engineering, Boston University
and with the Hariri Institute for Computing and Computational Sciences & Engineering
at Boston University.
Previously, I was a Prager assistant professor at
the Division of Applied Mathematics, Brown University
during 20092012. I completed my PhD at the
Department of Mathematics, University of Maryland at College Park in 2009 advised by Professor Mark Freidlin.
My undergraduate studies were in Applied Mathematics and Physics at the National Technical University of Athens in Greece.
(NTUA).
Research interests:
In recent years my work has focused on stochastic modeling and stochastic dynamical systems,
mathematical and computational methods in machine learning, uncertainty quantification in deep learning, scientific machine learning,
interacting particle systems,
statistical network modeling and statistical analysis, optimization and
applied mathematics, probability and stochastic processes.
I am interested in the development and analysis of rigorous methods to tackle problems arising
in various applications in statistics, science, engineering, and finance.
In particular, current research interests include the areas of:
 Mathematical and computational methods for machine learning algorithms
 Stochastic optimal control and optimization
 Stochastic online algorithms and deep learning for partial differential equations
 Monte Carlo methods and development of provablyefficient simulation methods
 Interacting particle systems, agent based modeling and related applications to biological systems, opinion and social dynamics
