[1] Gallego began his academic career at Columbia University in 1988, holding various positions within the Department of Industrial Engineering and Operations Research, promoted to full professor in 2000, and to the Liu Family Professorship in 2012.
[7] He currently serves as the Operations Research Area Coordinator in the School of Data Science at the Chinese University of Hong Kong, Shenzhen.
Gallego, in his early research, explored how companies could smoothly recover from production schedule disruptions, and on integrating inventory control and vehicle routing to optimize distribution systems.
[9] In the following year, he proposed dynamic pricing strategies for inventory management in industries with time-constrained sales, stochastic and price-sensitive demand, using intensity control, obtaining structural monotonicity, closed-form solutions, and extensions to more complex scenarios.
The study determined the optimal timing of mark-ups or mark-downs based on stochastic demand and price sensitivity to maximize revenues.
Through this research, he also provided optimal pricing and booking strategies, with potential extensions to multifare structures, network models, and other industries.
She also lauded the book's ability to cater to a diverse range of readers, from advanced undergraduates to those pursuing masters and PhD degrees.
