Saravanan Venkatachalam


Dr. Saran's research interests are in stochastic programming, large scale optimization, and discrete event modeling and simulation. Applications of interest include supply chain management, healthcare, pricing and revenue management, and energy management. Before joining the PhD program at Texas A&M University, Dr. Saran worked in industry for nine years for companies like JDA Software, Hewlett Packard where he had opportunities to develop and implement decision support systems (mathematical and statistical models) in the domains of consumer support, supply chain management, transportation, and pricing and revenue management.
