Bio

Grani A. Hanasusanto is an Assistant Professor of Operations Research and Industrial Engineering at The University of Texas at Austin (UT). Before joining UT, he was a postdoctoral researcher at the College of Management of Technology at École Polytechnique Fédérale de Lausanne. He holds a PhD degree in Operations Research from Imperial College London and an MSc degree in Financial Engineering from the National University of Singapore. He is the recipient of the 2018 NSF CAREER Award. His research focuses on the design and analysis of tractable solution schemes for decision-making problems under uncertainty, with applications in operations management, energy systems, machine learning and data analytics.

News

  • March 23-26, 2020: I have been invited as a speaker at the Centre de Recherches Mathématiques workshop on Decision Making under Uncertainty. I will be presenting our work on “A Robust Spectral Clustering Algorithm for Sub-Gaussian Mixture Models with Outliers.”

  • Sep 27, 2019: I am presenting our work on “Copositive Programming Approaches for Robust Optimization and Löwner-John Ellipsoid Problems” at the University of Texas at San Antonio.

  • I am organizing the stream on “Continuous Optimization under Uncertainty” at the 22nd Conference of the International Federation of Operational Research Societies. The triennial conference will be held on June 21-26, 2020 in Seoul, South Korea.

  • Areesh Mittal has successfully defended his thesis on “Copositive Programming Approaches for Robust Optimization and Löwner-John Ellipsoid Problems.” Congratulations!

  • Our paper on “Robust Quadratic Programming with Mixed-Integer Uncertainty” is accepted in INFORMS Journal on Computing.

  • Madhushini Prasad has successfully defended her thesis on “Approximation Schemes for Network, Clustering, and Queueing Models.” Congratulations!

  • Our paper on “Improved Conic Reformulations for K-means Clustering” is accepted in SIAM Journal on Optimization.

  • I am grateful and honored to be the recipient of a NSF CAREER Award.

  • I have been invited as a speaker at the seminal workshop on Distributionally Robust Optimization in Banff, Canada. The workshop aims to advance distributionally robust optimization (DRO) as a dominant modeling paradigm for optimization under uncertainty and to lay the foundations for industry-size applications. The workshop will bring together the world's leading experts in DRO and closely related fields.

  • Our paper on “Conic Programming Reformulations of Two-Stage Distributionally Robust Linear Programs over Wasserstein Balls” is accepted in the premier INFORMS journal Operations Research.

  • Our paper on “Data-Driven Inverse Optimization with Imperfect Information” is accepted in Mathematical Programming.

Misc

  • Prospective students: I am always looking for outstanding and self-motivated graduate students with strong mathematical background and exceptional proficiency in computer programming. Optimization under uncertainty is an exciting research area with plenty of challenges remain to be addressed. If you are interested in working with me, please apply here. I generally do not respond to emails inquiring for a PhD position, and I am currently unable to take on any teaching assistants, interns, and/or visiting scholars.
