- Healthcare Operations and Delivery; Operational systems engineering
- Medical decision making: monitoring for progression and “control” of controllable risk factors (application to Glaucoma) – machine learning approaches; Kalman filtering and control; clincal decision support tools
- Hospital Readmissions prediction and reduction
- Surgical planning and scheduling for access delay control; robustness approaches.
- Mortality risk based admissions/routing control to ICUs and intermediate/progressive care units
- Capacity management and planning and scheduling for outpatient care, particularly in integrated services networks
- Planning and scheduling for Clinical Research and Clinical Research Units
- Emergency Department redesign for improved patient flow
- Resilient supply chains: design of flexibility in supply chains, operations. Designing flexible backup supplier systems. Flexible operations for shipbuilding and maintenance.
Research methodologies incorporated:
- Stochastic processes, stochastic control, simulation, queueing networks, applied probability, Markov Decision Processes, sample path methods,
- Machine learning, online learning, online optimization
- Mathematical programming: emphasis on novel stochastic models of operations planning and control that are converted into math programs as a vehicle for numerical solution to otherwise intractable models.
- Medical decision making models based on state space modeling, Kalman filtering, Linear Quadratic Gaussian (LQG) control (a class of optimal stochastic estimation and control problems).
- Systems theory including inventory, supply chain, production, service science
My Teaching emphasizes applied probability and its use in operations engineering and management (queueing networks and their optimization and application, IOE 545) and healthcare/hospital systems improvement (e.g., IOE 481 Practicum in Hospital Systems)
