My major theoretical research interests lie in two fields. The first one incorporates stochastic models and, especially, the queueing theory, including models with impatience/abandonment, queues with uncertain arrival rate, approximation regimes and priority queues. The second field is statistics, including forecasting and survival analysis.

My main applied research interests include:
  • Call centers and IT support: staffing, cost analysis, satisfaction of service level agreements, operational regimes, impact of customer impatience, load forecasting.
  • Business Process Management: staffing and real-time scheduling in multi-process environment, simulation methods in BPM.
  • Health Care: applications of queueing models in operational management, load forecasting in hospitals, simulation of health care systems.
  • Water management: demand forecasting, maintenance planning, failure analysis.

I published a number of papers in the leading operations research and statistical journals. Main programming/statistical tools in my work are Matlab, SPSS and Java language.
