    Mathematical optimization and a multiple-case study

    Primary and secondary care are offered through outpatient clinics, where patients visit the hospital for a consultation or treatment. Some clinics work on a walk-in basis, but most work with scheduled appointments. Variation in the duration of consultations, random no-shows and walk-ins, and other sources of variability and uncertainty result in waiting time for patients and idle time for the clinician.

Research interests

Professor Wirjanto's research interests focus on developing statistical methodology for applications in the finance area. His work has centered on the modeling of volatility fluctuations in financial returns with applications to asset and derivatives pricing, portfolio selection, and the term structure of interest rates. His current work explores the use of finite mixtures of distributions as well as ultra high-frequency data for volatility forecasting, portfolio choice and financial risk management.
