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.   

Xin Jiang is a postdoctoral researcher at the Industrial and Systems Engineering Department, Lehigh University. He is also affiliated with the Program in the Foundations and Applications of Mathematical Optimization and Data Science (MODS). Xin received his Ph.D. degree in Electrical and Computer Engineering from University of California, Los Angeles (UCLA) in June 2022, where he was advised by Lieven Vandenberghe. He obtained his Bachelor's Degree in Electronic and Communication Engineering at the University of Hong Kong in 2015, and an M.S. degree in Electrical and Computer Engineering at UCLA in 2017. Xin's research interests broadly include theory and algorithms for optimization, especially semidefinite programming. He designs, analyzes, and implements efficient and scalable optimization algorithms for various applications from engineering, machine learning, and data science.
