I lead a number of applied research projects in collaboration with partner organizations, advise undergraduate and Master's students, and pursue my own research in healthcare and public policy.
January 2025 - Ongoing
Closing the Gap in Women's Cancer and Preventive Screening
Access Through Discrete-Event Simulation Modeling
Student Team Members: Alexandra Paiz Delgado, Luciana Salvatierra, Sophia Tu, Jakub Williams, and Yutong Wang
We are developing a discrete-event simulation based digital twin of the cervical and lung cancer screening pathways for women within the New York Presbyterian Hospital system to replicate current patient flow. This model serves as an experimentation environment in which alternative operational policies can be evaluated before real world implementation.
Project Partners: New York Presbyterian Hospital and Weill Cornell Medicine
January 2021 - May 2023
Improving Emergency Department Access to Computed Tomography Resources: A Multi-Step Approach
Advisers: Dr. Kayse Lee Maass and Kalyan Pasupathy
We developed a queuing model and an integer linear program to optimize CT scanner scheduling at a large academic medical center. The schedule is designed to scan 90% of ED patients within 80 minutes while also accommodating inpatient and outpatient demand.
January 2020 - December 2020
Modeling Hospital-Specific Bed, PPE, and Staff Surge Capacity During COVID-19
Team Members: Shane Yap, and Drs. Basma Bargal, Michael Rosenblatt, and James Benneyan
We developed a hospital-level forecasting tool that projects 1- to 30-day demand for beds, ventilators, PPE, medications, and staff during the COVID-19 pandemic. The tool provides an accessible resource to support short-term operational planning for health systems worldwide.
Project Partners: Lahey Hospital and Medical Center
