Feilim Colm Mac Gabhann, Ph.D.
Director, Hopkins Office for Undergraduate Research
Joint Appointment in Biomedical Engineering
Dr. Feilim Mac Gabhann is an associate professor of biomedical engineering at the Whiting School of Engineering and the Johns Hopkins School of Medicine. He is also a core faculty member of the Institute for Computational Medicine.
His research focuses on microvascular development and remodeling. Dr. Mac Gabhann serves as the director of the Hopkins Office for Undergraduate Research.
His team is currently engaged in projects that include inhibiting vascular endothelial growth factor signaling in cancer and promoting vascular endothelial growth factor signaling in ischemic disease.
Dr. Mac Gabhann received his undergraduate degree in chemical engineering from University College Dublin. He earned his Ph.D. in biomedical engineering from Johns Hopkins. He completed his postdoctoral fellowship at the Cardiovascular Research Center at the University of Virginia before returning to Johns Hopkins to join the faculty.
His work has been recognized with numerous awards, including the NIH Pathway to Independence Award, the American Physiological Society Arthur C. Guyton Award for Excellence in Integrative Physiology and the Alfred P. Sloan Foundation Research Fellowship.

Research & Publications
The Mac Gabhann Lab is involved in research projects including:
- Inhibiting vascular endothelial growth factor signaling in cancer: Using druggable multiscale computational models of the transport and signaling of vascular endothelial growth factor (VEGF), they test therapies to block the signaling pathways that lead to vascularization of tumors and metastasis.
- Promoting vascular endothelial growth factor signaling in ischemic disease: Using druggable multiscale computational models of the transport and signaling of VEGF, they test therapies to increase nonpathological pro-angiogenic signaling that lead to increased perfusion of muscle and other tissues vulnerable to ischemia.
- Microvascular network organization: They study the variability in microvascular network structure in mice from different strains, both before and after intervention. Induced ischemic or other injury results in different remodeling responses that may hold the key to therapy development.
- Impact of extracellular matrix on VEGF signaling: Using a combination of in vitro, in vivo and in silico approaches, they study the ability of extracellular matrix sequestration of VEGF to impact the extracellular VEGF signal as perceived by cell-surface receptors.
- Molecular mechanisms of small-genome diseases – host-virus interactions of HIV: They have created molecular-level simulations of HIV, that complement existing models of viral development and cellular infection. By including the effects of the genes that HIV expresses, particularly those that have evolved to combat our host defenses, they can test new therapies that boost host antiviral responses.
