Postdoctoral researcher, KU Leuven

[CV]

I am currently a post-doctoral research associate at KU Leuven. I have completed my Ph.D. under the supervision of Prof. dr. Tias Guns. My research falls at the confluence of machine learning (ML) and combinatorial optimization problem (COP).

In my PhD, I have studied Decision-focused learning. In decision-focused learning, ML prediction is followed by COP for decision-making. The goal is to train the ML model, very often a neural network model, directly considering the error after the COP. The primary challenge in the implementation decision-focused learning is how to embed the COP into the ML training loop. To address this challenge, I have developed a differentiable optimizer, which enables passing the gradient through the COP for training the ML model. I am also interested in scalable decision-focused learning, so that it can be applied in real-life COPs, which are often NP-hard and time-consuming to solve.
