Embedded Files
I am a mixed-methods researcher focused on health technology in the Philadelphia area. I graduated with a PhD in Information Science at the College of Computing and Informatics at Drexel University, Philadelphia – working with Dr. Aleksandra Sarcevic. My dissertation research focused on designing and developing technologies to reduce errors and improve efficiency in high-risk, error-prone healthcare settings, such as emergency medical and trauma resuscitation.
I graduated from the University of Chicago with a BA in Biological Sciences in 2017. Upon graduation, I worked at Cerner Corporation where I worked as a consultant for State and Local Government MMIS programs. I completed my Master of Public Health with customized studies in Biostatistics from the Johns Hopkins Bloomberg School of Public Health in 2020. I love to watch movies, knit sweaters, go on runs, and spend time with my cats Barb and Gus
