PhD Student
My research interests are focused on the control-theoretical aspects of free boundary problems arising in fluid mechanics, and more recently, deep learning from a mathematical control perspective.

Borjan Geshkovski is a PhD Student at Universidad Autónoma de Madrid (UAM). He earned a MSc in Mathematics at the University of Bordeaux, during which he did an internship on the topic “Obstacle problems: theory and Applications” within the DyCon team.

Currently, he is studying for a PhD in Control Theory under the supervision of Prof. Enrique Zuazua (FAUUniversity of Deusto and Universidad Autónoma de Madrid).

Master’s Thesis. Obstacle Problems: Theory and Applications

Advisor: Prof. Enrique Zuazua
Abstract: In this master thesis, we present a study of the analytical and optimal control properties for the elliptic and parabolic obstacle problems. The obstacle problem is one of the simplest and most physically relevant free boundary problems. From a mathematical perspective, similar questions as for classical partial differential equations (well-posedness, regularity, optimal control) are addressed, as well as the conception of appropriate numerical schemes and computer simulations of the these problems. This work was supported by the Advanced Grant DyCon (Dynamic Control) of the European Research Council Executive Agency (ERC).
