Gina Merchant, PhD
Dr. Merchant is a National Library of Medicine Postdoctoral Fellow at the University of California San Diego in the Division of Biomedical Informatics, Department of Medicine, with a secondary appointment in the Department of Family Medicine and Public Health. She also lectures at California State San Marcos. Her undergraduate and masters degrees are in Psychology, and her doctorate is in Public Health with an emphasis on Health Behavior. Dr. Merchant's research is at the intersection of psychology, public health informatics, and data science. Her work broadly examines how online and offline social networks influence our health behaviors and healthcare decision-making. Dr. Merchant quantitatively and qualitatively investigates how spending time on social media platforms, creating and engaging with content, affects our health. She seeks to uncover methods to conduct large-scale content analysis of unstructured text data that is exchanged in online networks. Once we are able to interpret these data, she believes we will have a better understanding of how to intervene in virtual spaces to promote health-enhancing behaviors, and better predict who is at risk for health impairing behaviors. Dr. Merchant's work aims to discover ways to leverage social media and other Web 2.0 technologies to improve individuals’ health, and better understand how on- and offline social networks synergistically/antagonistically influence health attitudes and behaviors. Dr. Merchant is active in the R community, and is an advocate for increasing diversity in coding, especially among women in the behavioral and social sciences.

In her spare time she enjoys playing soccer, running, cooking, gardening, and hanging out with her family.
