Seyedeh Nazanin Khatami, PhD

Nazanin is currently a postdoctoral research fellow at Harvard Medical School and Massachusetts General Hospital. She joined MPEC in January 2022. As part of the MPEC modeling team, she is working closely with Dr. Krishna Reddy on developing a tuberculosis transmission module.

Nazanin received her PhD in Industrial Engineering and Operations Research from the University of Massachusetts (UMass) Amherst. She also holds an MS in Electrical and Computer Engineering from UMass Amherst. Her research focuses on disease modeling, control, and optimization. During her PhD, she closely collaborated with the HIV Division at the CDC where she developed a sequential decision-making model to control HIV at a national level using reinforcement learning algorithms.

Laura Platt, MD

Dr. Platt is an Infectious Diseases physician at Brigham and Women’s hospital and a medical consultant at the Massachusetts Department of Health’s Office of HIV/AIDS.

Her interests include using methods of epidemiology and implementation science to reduce disparities in care for HIV and sexually transmitted infections. She is particularly interested in integrating infectious disease diagnosis, prevention, and treatment services into community-based settings to better reach key populations.

She earned her MD from Duke University and completed residency in internal medicine at Johns Hopkins Hospital.

Katie Rich

Katie is currently a fourth year medical student at Harvard, who is spending this year working with MPEC mentored by Dr. Hyle. Her prior research has focused on access to care, with a focus on individuals with HIV and substance use disorders, as well as those who have been incarcerated. She has been involved in projects both domestically in Connecticut, as well as internationally in Peru and Ukraine. Before coming to Boston for medical school, she earned an MPH from Yale, where she was introduced to cost-effectiveness analysis through coursework, however, her prior work primarily used survey methods. While at MPEC she plans to focus her project to better understand disparities within the US HIV continuum of care, and to assess interventions to reduce barriers to HIV care.
