Control, Optimization, and Scientific Computation:
Control, Optimization, and Scientific Computation:
My research revolves around scientific computation methods for optimization and control, nonlinear PDEs, high-dimensional approximation and agent-based models across scales. Some relevant keywords below.
Foundations: Dynamic optimization with ODE/PDE constraints; large-scale and sparse optimization; mathematical control theory; high-dimensional approximation; numerical methods for Hamilton-Jacobi PDEs and dynamic programming; optimal transport, mean-field control/games.
Applications. Scientific Machine Learning: data-driven control design in trajectory optimization, epidemiology, and large-scale dynamics. Agent-based models: nonlocal PDES, collective behaviour, consensus control. Nonlinear control design: power electronics, swarm robotics, reinforcement learning. Control of PDEs: fluid flow and vibration control, optimal actuator design.
Please have a look at Research , Publications and CV for more details. I'm always happy to discuss about any of these topics for projects and supervision, so please feel free to get in touch!
Prospective PhD/postdoc applicants, please read before contacting me. I'm always interested in hearing about candidates with a keen and demonstrable interest on applied and computational mathematics, understood in a wide sense. Being that said, please be aware of the following:
I don't supervise projects on control theory/engineering, reinforcement learning, or multi-agent systems which do not have a primary computational component.
In practice, all my students have a maths BSc/MSc, this is essential for our day-to-day communication and PhD research. This is not about gatekeeping, it's about whether I'm the right person to supervise you. Exceptional candidates with engineering degrees can be considered in the frame of a multidisciplinary project, but I advertise these separately.
PhD studentships for international students are extremely competitive at Imperial. I don't want to waste your time unless I'm certain there's a reasonable chance that you will be funded.
Please do not contact me with last minute requests for sponsorship. And please, do not send me a LLM wall of text, it's noticeable.
Being able to read and follow the instructions above is a skill that I value very highly :)
Short Bio
Short Bio
I'm Reader in Computational Optimisation and Control at Department of Mathematics, Imperial College London. Prior joining Imperial in 2021, my criminal record includes: Assistant Professor in Applied Mathematics, University of Nottingham (2019-2021), Imperial College Research Fellow (Maths, 2017-2019), Research Scientist (Optimization and Control Group, 2013-2017), RICAM Linz, Austrian Academy of Sciences, and Postdoctoral Researcher (Maths, EU ITN-SADCO, 2011-2013), Sapienza University of Rome.
I'm originally from Chile and grew up in front of the Pacific, in Viña del Mar. I received a B.Sc. in Mathematical Engineering and a M.Sc. in Electronic Engineering from the Federico Santa María Technical University in Valparaíso. In 2008 I moved to Norway, where I got a Ph.D. in Mathematics in 2012 from the University of Bergen (with some periods away from the rain in Oslo and Trento).

We are organizing a 1 day workshop (Feb. 6) on New Technologies for Conservation Science as part of our Turner Kirk Trust project on Understanding collective animal behaviour under extreme climatic events.
Starting from 2025, we are starting a new EPSRC Centre for Doctoral Training in Collaborative Computational Modelling at the Interface (CCMI) (I'm Co-Director for Training :))! There will be openings for PhDs and applications will start in fall 2024. If you are interested with me, please send me a non-generic (LLM-generated) email as soon as possible.
I've led the design of a new stream on Scientific Computing & Machine Learning for our Applied Maths MSc. You can read the press release here!
We've restarted the series on Learning, Computation, and Control (LC2) at Imperial. Past talks are hosted here.
