Portrait of Luke J Mortensen

Academic Profile

Dr. Mortensen received his B.S in Bioengineering from the University of Toledo in 2003, and his Ph.D. from the University of Rochester in Biomedical Engineering in 2011 under Prof. Lisa DeLouise. His research focused on understanding the impact of sunburn on skin and skin cell interaction with nanoparticles, and confocal microscopy of nanoparticle skin penetration. Following his Ph.D., Luke served as a postdoctoral researcher in the Wellman Center for Photomedicine at Massachusetts General Hospital / Harvard Medical School with Prof. Charles Lin. While at MGH/HMS he worked on developing 2 photon intravital microscopes, engineering mesenchymal stem cell therapeutics, and investigating stem cell roles in bone regeneration. Currently, Luke is an associate professor with joint appointments in Regenerative Medicine and Engineering at the University of Georgia. His research primarily focuses on regenerative medicine in bone and muscle. Long term goals of his research are to create next generation super-resolution 2 and 3 photon microscopes for imaging cell organelles through opaque bone, and to leverage key imaging and lipid metabolite features associated with MSC therapeutic potency to biomanufacture efficacious cell therapies.
