This page lists the current doctoral students under my supervision as well as some doctoral students and postdocs with who I have/had strong interactions during their research activities.
News: Doctoral research funds & a postdoctoral position in Discrete Optimization are currently available at CORE. If you are interested, contact me.
Current Doctoral Students
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. A deep reinforcement learning approach for the stochastic inventory problem. Submitted to Operations Research, 2021.
Roberto is carrying out his 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 are currently focusing on scheduling problems. I have collaborated with Roberto in the context of the following article:
- D. Catanzaro, R. Pesenti, R. Ronco. A new fast and accurate solution approach for the automatic scene detection problem. To appear in Computers and Operations Research, 2021.
- D. Catanzaro, R. Pesenti, R. Ronco. On Energy-efficient Scheduling with Time-of-Use Costs. Working paper, 2021.
Roberto will be visiting CORE between September and October 2021, and will defend his doctoral thesis in February 2022.
Former Doctoral Students
Martin graduated in economathematics at the University of Cologne (2017). At present, I am supervising his doctoral studies, which focus on specific combinatorial and optimization aspects of computational phylogenetics. So far, Martin authored the following manuscripts:
- D. Catanzaro, M. Frohn, O. Gascuel, and R. Pesenti. A Tutorial on the Balanced Minimum Evolution. To appear in the European Journal of Operational Research, invited article, 2021.
- M. Frohn. On the approximability of the Fixed-Tree Balanced Minimum Evolution Problem. To appear in Optimization Letters, 2021.
- D. Catanzaro, M. Frohn, and R. Pesenti. An information theory perspective on the Balanced Minimum Evolution Problem. Operations Research Letters, 48(3): 362-367, 2020.
Martin defended his doctoral thesis on October 27 2021.
Collaborations with Former Doctoral Students
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:
- D. Catanzaro and C. Engelbeen. An integer linear programming formulation for the minimum cardinality segmentation problem. Algorithms, 8(4), 999-1020, 2015.
Celine is currently tenured lecturer at ICHEC.
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:
- L. Porretta, D. Catanzaro, B. V. Halldórsson, and B. Fortz. A Branch&Price Algorithm for the Minimum Cost Clique Cover Problem in Max-Point Tolerance Graphs. 4OR, 17(1), 75-96, 2019.
- D. Catanzaro, M. Labbé, and L. Porretta. A class representative model for pure parsimony haplotyping under uncertain data. PLoS One 6(3): e17937, 2011.
Luciano is currently research scientist at OM Partners.
