Based at the University of Texas Medical Branch (UTMB) in the Neurobiology Department and the Sealy Institute for Drug Discovery (SIDD), the Koss lab aims to bioengineer and develop peptides and peptide-related biomaterials towards bioengineering the neuroimmune response from CNS neural glia: microglia and astrocytes. In particular, we are interested in understanding and developing peptides for the mediation of glial rejection of implanted biomaterials and glial scar tissue (gliosis), biomarkers for neurodegenerative disease, and hyaluronic acid-mediated wound healing.
Rejection of implantable device/material in CNS. Shown here is an electrode being targeted by microglia, the resident immune cell, which subsequently recruit astrocytes to generate the glial scar (PMID: 30414483).
Our Approach:
The Koss lab employs several cutting edge techniques, including peptide-discovery through phage display, high-throughput cell culture-based microglial and gliotic phenotype development, wireless thermal/bioelectric biosensors, electron transfer in peptides, mitochondrial gene therapeutics, and peptide bioengineering though multi-faceted helical nets, molecular dynamics, and artificial intelligence.
I’m an early stage investigator assistant professor at the University of Texas Medical Branch (UTMB) and the Sealy Institute for Drug Discovery (SIDD). I'm a classically trained chemical engineer from Alberta with a computer process control specialization. I have a PhD in Chemical Engineering from the University of Alberta and the National Institute for Nanotechnology in Canada. My post-doctoral fellowships were in Northwestern, the Department of Veteran Affairs, and the University of Arizona where my research was funded by the Canadian Institutes for Health Research (CIHR) and the American Heart Association (AHA). I have a startup that provides peptides engineering and molecular dynamic services called Peptide Dynamics.
