Other titles and affiliations
Since September 2016, Marilène Cherkesly has been an assistant professor of operational management with the Department of Management and Technology at the Université du Québec à Montréal (UQAM). She first received a B.A. in business administration, with a concentration in operational management and logistics, from HEC Montréal in 2011. She then obtained her PhD in applied mathematics from Polytechnique Montréal in 2015, under the supervision of Professors Guy Desaulniers and Gilbert Laporte. During her university career, she received the Alexander Graham Bell Canada Graduate Scholarship from the Natural Sciences and Engineering Research Council of Canada (NSERC) and the Quebec Lieutenant Governor’s Youth Medal in 2015. After her PhD, she was a postdoctoral trainee affiliated with UQAM’s School of Management Science, with the McCormick School of Engineering at Northwestern University and with the Interuniversity Research Centre on Enterprise Networks, Logistics and Transportation (CIRRELT). During that time, she received an NSERC Postgraduate Scholarship.
Her research interests are focused on developing methods based on operational research to optimize real, complex transportation and logistics systems. For her PhD, she worked on the development of branch-price-and-cut and metaheuristic algorithms for parcel handling problems in road transport, to improve worker safety. During her postdoctorate, she worked on the mathematical modelling and resolution of a logistics network design problem in Liberia, in partnership with a local organization there. More recently, she has developed expertise in integrating localization and transport problems, both in general contexts and in the area of humanitarian logistics. Her ongoing projects touch on the following: designing healthcare networks in hard-to-access areas, designing routes for mobile clinics in war zones, and integrating real, complex constraints (e.g. handling, coverage, localization) into vehicle routing problems. There are two aspects of research that inspire her: the real problems arising from humanitarian logistics and the development of efficient intelligent algorithms for logistics and transportation problems. She wants to continue collaborating on humanitarian logistics and merchandise transport problems in conjunction with real-world applications and with academia.

We are proud to announce that the 2020-2021 OR/MS Scientific Writing Activity was a complete success, even in the face of a global pandemic. This year, we received ten final extended abstracts: four in logistics, two in stochastic optimization, two in machine learning, one in electricity, and one in scheduling.
Congratulations to the teams selected to lead new fundamental research projects!
The third edition of the scientific writing activity just ended. The goal of this activity is to experiment the publication process of a scientific paper by mimicking the submission of a paper and peer reviewing. This year again, several students took part in the activity to develop their writing skills. The final submissions have been evaluated by a jury of professors that have highlighted the high quality of the works submitted. We wish to congratulate the winners of this year’s activity:
- 1st place, tie: Gabriel Homsi for his paper "Dynamic and Stochastic Rematching for Ridesharing Systems: Formulations and Reductions"
- 1st place, tie: Jørgen Skålnes for his paper "A new formulation for the inventory routing problem"
- 2nd place: Peyman Kafaei for his paper "Deep Q-learning for simultaneous Beam Orientation and trajectory optimization for Cyberknife"
- 3rd place: Nazgol Niroumandrad for her paper "A Reinforcement Tabu Search Algorithm"
- Honorable mention: Tayeb Mhamedi for his paper "A Branch-Price-and-cut algorithm for the two echelon vehicle routing problem with time windows"
A summary of the winners’ work is available hereafter.
Congratulations are in order for all the participants of this year and for the quality of their work! We welcome all students to join us next year for the fourth edition of the writing activity!
