Ph.D., Princeton University, 2008
B.S., EE University of Notre Dame, 2003
Prof. Howard attended Notre Dame as an undergraduate and received his BSEE from the electrical engineering department. Following graduation in 2008, Scott attended graduate school at Princeton where he studied the design, fabrication, and characterization of "quantum cascade lasers" -- tunable mid-infrared semiconductor injection lasers that emit at wavelengths between ~4-12 microns. Dr. Howard worked as a post doctoral research associate in Applied and Engineering Physics at Cornell University from 2008-2011. There he worked on medical imaging technologies that used non-linear optics to see 3D microscopic images in living tissue without having to take a biopsy. Scott has been at Notre Dame since 2011 where he teaches in the Department of Electrical Engineering and leads an interdisciplinary research group in advanced imaging techniques. His work is supported by the NSF, DHS, and USDA. in 2016, Prof. Howard was awarded an NSF CAREER award.
At Notre Dame, Dr. Howard leads a research group that is finding ways to image chemical information in complex environments (such as biomedical and trace explosive detection applications) that exceeds the limitations of current techniques. The Howard Research Group has developed microscope platforms that combine "multiphoton microscopy" and "fluorescence lifetime imaging" in novel ways to quantitatively image 3D microscopic chemical concentrations in living tissue faster than theoretically possible by conventional commercial techniques, and has started extending this work to improved optical resolution and depth of penetration in tissue. His group also works on combining advanced imaging technology with mid-infrared semiconductor lasers to image trace residues of explosives in a low-cost, field portable platform.
Summary of Activities/Interests
Research Interests: Prof. Howard's research focuses on how the interaction of photons and tissue can be used to aid diagnosis and fundamental research in biological fields. The group's work thus spans optoelectronic device development (e.g. QCLs) to be used as sources in systems, technique development (e.g. overcoming fundamental limitations to speed/sensitivity, resolution,and depth of MPM-FLIM), contrast agent development (e.g. encapsulation of chemically-sensitive nonlinear optical dyes for biocompatibility)
