How can we make machines learn from as little data as possible?
How can we make machines that effectively deploy their knowledge in novel situations?

I try to answer these questions by investigating how can we use programming languages to represent what artificially intelligence agents know and how they act. In pursuing this goal, I work on program synthesis, which focuses on learning programs from examples, and probabilistic programming, which focuses on representing and reasoning with probabilistic models represented as computer programs. In both fields, representing knowledge as a program is the key feature that allows us to capture knowledge of arbitrary complexity, use it flexibly, and acquire it from little experience.

I am also interested in application of program synthesis and probabilistic programming in scientific discovery (especially geophysics), transportation, robotics and planning.

Before joining TU Delft, I was an FWO-funded postdoctoral fellow in the DTAI lab at KU Leuven working with Hendrik Blockeel and Luc De Raedt, where I also obtained my PhD. I was a visiting researcher at MIT, University of Oxford, and NEC Laboratories Europe.
