Biography

After completing graduate work, Dr. Alexandrakis was a postdoctoral fellow at Massachusetts General Hospital / Harvard Medical School where he worked on quantitative intravital two-photon microscopy techniques for the analysis of barriers to drug delivery in tumor-bearing mice. He then pursued further postdoctoral work at UCLA where he contributed to the development of a combined optical/PET mouse imaging system and was also exposed to clinical multi-modality imaging.

In collaboration with faculty at UT Southwestern Dr. Alexandrakis investigates the dynamics of proteins involved in cancer pathways by use of quantitative confocal and two-photon cellular microscopy as well as nanosensing techniques. He is also actively pursuing several projects involving the technological development and clinical dissemination of functional Near-Infrared Spectroscopy (fNIRS), which is an optical brain imaging technique.
