Supervision Activities

This page provides an overview of the activities that I have carried out so far in the context of postgraduate studies. The page lists the current and the former doctoral students and postdoctoral fellows for which I acted as an advisor, as well as the doctoral students and postdocs with who I had (and in most cases I still continue to have) strong scientific collaborations. A part from the postgraduates involved in doctoral studies in fieri, only the fellows that succeeded to complete their appointments and that published with me are listed below. The scientific production reported in this page may not be updated very frequently, so some information could be outdated.

News: a postdoctoral position in Discrete Optimization are currently available at CORE. If you are interested, contact me.

Current Doctoral Students and Postdocs

Henri Dehaybe

Henri graduated in Management Engineering at the Université Catholique de Louvain (2017). Henri’s doctoral studies are currently co-supervised by my colleague, Philippe Chevalier and myself. So far, we coauthored the following articles:

  • H. Dehaybe, D. Catanzaro, and P. Chevalier. Continuous deep reinforcement learning for non-stationary stochastic inventory optimization. European Journal of Operational Research, accepted, 2023.
Emma Legrand

Emma graduated in Computer Science Engineering at the Université Catholique de Louvain (2023) and started in September 2023 her doctoral studies in co-supervision with my colleague Pierre Schaus.

Brieuc Pierre

Brieuc graduated in Computer Science Engineering at the Université Catholique de Louvain (2023) and started in September 2023 his doctoral studies in co-supervision with my colleague Mathieu Vanvyve.

Former Postdocs

Dr. Allan Sapucaia

Doctor in Combinatorial Optimization from the University of Campinas (2017-2022) under the supervision of both Pedro J. de Rezende and Cid C. de Souza. His doctoral studies focused on computational geometry and integer linear programming, with special attention to the development of decomposition techniques for partitioning, packing and covering problems. Allan got both the von Neumann Award (Highest GPA among C.E graduates – Institute of Computing, UNICAMP 2017) and the Babbage Award (Highest GPA among C.E students – Institute of Computing, UNICAMP 2015) and during the academic years 2022 and 2023 he worked, under my supervision, on optimization problems defined over specific classes of acyclic connected graphs.

  • D. Catanzaro, R. Pesenti, A. Sapucaia, and L. Wolsey. Optimizing over path-length matrices of unrooted binary trees. Submitted to Mathematical Programming, 2023.
  • D. Catanzaro, R. Pesenti, and A. Sapucaia. Characterizing path-length matrices of unrooted binary trees. In preparation, 2023.
  • D. Catanzaro and A. Sapucaia. A matheuristic for the Balanced Minimum Evolution Problem, In preparation, 2023.

As of January 2024, Allan moved to the department of network optimization of Amazon EU.

Former Doctoral Students

Martin Frohn

Martin graduated in economathematics at the University of Cologne (2017). At present, I supervised his doctoral studies, which focused on specific combinatorial and optimization aspects of computational phylogenetics. Martin co-authored the following manuscripts:

Martin defended his doctoral thesis on October 27 2021 and currently is postdoc at the Technical University of Eindhoven.

Collaborations with Former Doctoral Students and Postdocs

Andrea Gasparin

Andrea graduated in Computer Science Engineering at the University of Trieste (2017) under the supervision of my colleague, Lorenzo Castelli. I co-supervised his doctoral studies, part of which carried out at CORE during the fall 2022.

Andrea was awarded his Phd on December 2023 and currently is postdoc at the Department of Computer Science Engineering at the University of Trieste.

Roberto Ronco

Roberto carried out his undergraduate and doctoral studies in Computer Science and Operations Research at the University of Genoa, Italy, under the supervision of Massimo Paolucci. Large part of his research efforts focuses on scheduling problems. I have collaborated with Roberto in the context of his doctoral studies, part of which carried out at CORE during the fall of 2021.

Roberto defend his doctoral thesis on February 2022 and currently is a researcher at the Italian National Research Council (CNR).

Céline Engelbeen

Céline completed her doctoral studies at Department of Mathematics of the Université Libre de Bruxelles in 2010, under the supervision of my colleague Samuel Fiorini. She worked on constrained decompositions of integer matrices in the context of intensity modulated radiation therapy. We collaborated during her postdoctoral studies on the following article:

Celine is currently tenured lecturer at ICHEC.

Luciano Porretta

Luciano graduated in Computer Science at the University of l’Aquila, Italy, under my co-supervision (2010). He carried out his doctoral studies at the Graphs and Mathematical Optimization Unit of the Computer Science Department of the Université Libre de Bruxelles, Belgium, under the supervision of my colleague Bernard Fortz. He was awarded the title of Doctor of Sciences in January 2018. I have intensely collaborated with Luciano on a large part of his doctoral studies, focused on models and methods in genome-wide association studies. Our collaboration gave rise to the following articles:

Luciano is currently research scientist at the belgian branch of OM Partners.
