Dayna MartinezDayna Lee Martinez, PhD

Faculty Associate

Dayna was s a post-doctoral research associate at the Healthcare Systems Engineering Institute and now teaches in Northeastern's MEIE Department. Her applied work included projects in several Boston area health systems such as MGH and CHA. She has worked on projects aimed to reduce hospital infections, perioperative supply chain costs, and categorize specialty referrals based on appropriateness. Her dissertation work was focused on developing optimal non-pharmaceutical interventions (such as quarantine and school closure) for the mitigation of pandemic influenza outbreaks. She developed a statistical ANOVA-based design approach that uses a detailed agent-based simulation as an underlying model and tested the designed NPIs on simulated outbreaks using various virus transmissibility scenarios.
