Welcome to my homepage!

My name is Parshan Pakiman. I am a Ph.D. candidate in Information and Decision Sciences (IDS) at the University of Illinois Chicago (UIC). I am grateful for being co-advised by Selva Nadarajah and Negar Soheili. Before joining UIC, I received my Bachelor of Science in Mathematics and Applications from the School of Mathematics, Statistics, and Computer Science at the University of Tehran.

My main research interests include:

(i) Off-the-shelf reinforcement learning (RL) algorithms: Mitigating the burden of model selection and parameter hand-engineering to broaden the use of RL in business applications (i.e., dynamic pricing with demand learning, options pricing, marketing campaign optimization, inventory control) and making it accessible to non-experts.

(ii) Learning from sequential decisions: Uncovering unknown parameters of an optimization problem used to make historical decisions via inverse RL and then using learned parameters in a forward RL to enhance past decisions.

(iii) Technical expertise: Advancing the above themes by developing methods and theory based on approximate linear programming, random features, information relaxations and duality, and online convex programs.

July 25-28, 2022: Looking forward to joining the ICCOPT 2022 conference at Lehigh University and presenting my work!

October 16, 2022: Very excited to co-organize a session with professor Selva Nadarajah on Recent Advances in Sequential Decision Making at the 2022 INFORMS Annual Meeting. We have an amazing set of speakers, professors Canan Ulu, Michael Pavlin, and Peter Frazier.

April 24, 2022: I will give two talks at the 32nd Annual POMS conference. The title of my presentations are Balancing Financial and Social Objectives via Decision Learning and Menu Optimization and Self-adapting Reinforcement Learning for Financial and Real Options.

March 13th, 2022: I am co-organizing a session with Professor Selva Nadarajah at the 2022 INFORMS Optimization Society, conference, which will be held at Greenville, SC. The session will focus on linear programming approximations for large-scale applications. The list of talks will be announced soon!

October 24th, 2021: At INFORMS 2021, I will chair the Recent Advances in Reinforcement Learning session, which is part of the Optimization under Uncertainty cluster.
