Post-Docs and Ph.D. Students

Tommaso Giovannelli is a postdoctoral researcher at Lehigh's Department of Industrial and Systems Engineering working with Luis Nunes Vicente since June 2020. Giovannelli received his Ph.D. in Operations Research in May 2021 from Sapienza University of Rome, where he obtained his BSc and MSc in Management Engineering in 2015 and 2017, respectively. From January 2020 to May 2021 he stayed at Lehigh ISE as a visiting scholar. Giovannelli's methodological research interests include nonlinear optimization, derivative-free optimization, and simulation-based optimization. His main application areas concern healthcare operations, machine learning, and transportation systems. He won a doctoral award from the EURO Working Group on Operational Research Applied to Health Services (ORAHS) of the International Federation of Operational Research Societies (IFORS) at the Doctoral Consortium ORAHS 2019, Karlsruhe, for his research proposal titled A simulation-based optimization approach for the improvement of the emergency department management.  

Nimita is a Postdoctoral Research Associate at the Department of Industrial and Systems Engineering at Lehigh University since June 2023. Nimita received her Ph.D. in 2022 jointly from Indian Institute of Technology Bombay and Monash University where she was advised by Prof. Vishnu Narayanan and Dr. James Saunderson. She was a postdoctoral fellow at ICERM, Brown University from September 2022 to May 2023. Nimita is broadly interested in memory-efficient techniques as applied to large-scale convex optimization problems, integer and combinatorial optimization, and non-smooth optimization.
