About
Ruihao Zhu is currently a 5th-year candidate for the Interdisciplinary Ph.D. in Statistics (IDPS) at the MIT Institute for Data, Systems, and Society (IDSS) and Laboratory for Information & Decision Systems (LIDS). He has the pleasure of being advised by David Simchi-Levi. Born in Guangzhou, China, Ruihao received his B.Eng. degrees in Electrical Engineering and Computer Science from both Shanghai Jiao Tong University and the University of Michigan in 2015. He spent the summers of 2020 and 2019 as a research scientist intern with Amazon Supply Chain Optimization Technologies (SCOT) and Google Research Mountain View.
Ruihao's research seeks to help organizations to improve decision-making in uncertain and dynamically changing environments using tools from data analytics, with a focus on applications in revenue management, supply chain management, and fairness & privacy. As part of it, he enjoys collaborating with companies across different industries, such as consumer packaged goods and medical devices manufacturing. His works have been recognized by an Honorable Mention in INFORMS George E. Nicholson 2019 Student Paper Competition and a Finalist in POMS-JD.com 2019 Best Data-Driven Research Paper Competition.
