Leadership Team
Lauren Gardner
ASSOCIATE PROFESSOR of Civil Engineering
CSSE Co-Director
Dr. Lauren Gardner is an Associate Professor in the Department of Civil Engineering at Johns Hopkins University. She leads interdisciplinary research efforts on the topic of bio-secure mobility, which utilizes network optimization and mathematical modeling to improve our understanding of disease spreading patterns and risk as a function of transportation systems, land use, climate and population demographics. She is also a member of the Infectious Disease Dynamics (IDD) Group in Johns Hopkins Bloomberg School of Public Health. Prior to joining JHU she was a faculty member at the School of Civil and Environmental Engineering at the University of New South Wales (UNSW) Sydney. She is a leading member of the Research Centre for Integrated Transport Innovation (rCITI), and Visiting Scientist at Commonwealth Scientific and Industrial Research Organisation (CSIRO), serving as the transport lead on the DiNeMo Project.
