Autonomous ridesharing represents the future of public transit. "Dynamic Ridehailing with Electric Vehicles," published in Transportation Science, introduces AI methods that match riders with vehicles and proactively position the fleet for future use and charging needs.
Time is valuable. Stop waiting around for the cable guy. Published in Transportation Science, "Optimal Service Time Windows" prescribes a strategy to shrink service windows in the face of uncertain demand without eroding customer service levels.
Don't let the uncertainty of public charging stall fleet electrification. Published in Transportation Science, "Electric Vehicle Routing with Public Charging Stations" engineers optimization tools to generate delivery routes in the face of congestion.
Forecasts fail when they ignore volatility. Moving beyond a single-scenario mindset, executives and professionals implement hedging strategies that insulate their organizations from the unknown by allocating resources across a range of outcomes.
Undergrads personalize mathematics. What should we do (or not) in a day or a lifetime? What amount of new and familiar yields the most fulfillment? How much chaos can we manage? A course about the problems we face, and how math empowers us to design a more meaningful life.
Doctoral students master the foundations of reinforcement learning. They develop strategies that balance immediate performance with long-term gains. The course synthesizes modern methods across dynamic programming, optimal control, and AI to solve large-scale sequential decision problems.
Role. I direct the master's program in supply chain management at Saint Louis University's Chaifetz School of Business, where my research explores the intersection of logistics, uncertainty, and decision making.
Education. I earned a PhD in business analytics from the University of Iowa and completed my MS and BS in industrial engineering, along with an MBA, at the University of Missouri.
Research. I publish in journals such as Operations Research and Transportation Science. The Institute for Operations Research and the Management Sciences (INFORMS) honored my research with best paper awards.
Teaching. I received distinction at SLU as the MBA Faculty of the Year and as a top educator in St. Louis through the Emerson Excellence in Teaching Awards.
Consulting. Beyond research and teaching, I partner with organizations to engineer solutions for complex logistics, operational, and supply chain challenges.
