Professor Miguel Anjos
Mathematical optimization provides guaranteed optimal or near-optimal solutions for various classes of large-scale optimization problems. Much of my research, in collaboration with industry partners, is about improving optimization models and algorithms used in real-world applications. In particular, optimization helps improve the overall performance of the electricity system that is of critical importance to our society. My research contributes to the development of smart grids which combine a traditional electrical power system with a two-way flow of information and energy between suppliers and consumers. This combination can deliver higher integration of wind and solar power, energy savings, and increased reliability and security.

My research interests are in using Monte Carlo and optimization methods for statistical problems motivated by applications. I have started my research career in applied probability, which was useful in analysing Markov Chain Monte Carlo and Sequential Monte Carlo methods, as well as the efficiency of optimization methods for stochastic functions. One area of application of such methods Is in the field of inverse problems, in particular chaotic dynamical systems that can be modelled by PDEs and ODEs. In recent years, there have been spectacular advances in optimization methods that scale to much larger problems than previously possible, by clever use of sparsity. I am keen to use them to attack challenging statistical problems.
