Dr. Samuel M. Hudson was educated at North Carolina State University and holds a doctorate in Fiber and Polymer Science (1981). He was then, a senior chemist with the DuPont Co.’s Pioneering Research Lab (1981-1987) at the Experimental Station in Wilmington, DE. While there, his research interests included the study of the biopolymers chitosan and the silk-like fibroin proteins. In 1987 he joined the faculty at the College of Textiles, NCSU, where he is presently Professor of Polymer and Color Chemistry. He cofounded and is Chief Scientific Officer of Karamedica, Inc. He is also on the scientific advisory board of Bolt Threads, Inc.
Chitosan has a number of bioactivities, including being a hemostatic and having antimicrobial properties, which makes it attractive for medical textile applications. Fibroins and chitosan have outstanding characteristics as structure forming materials. Dr. Hudson’s laboratory has developed a number of different physical forms of chitosan and more recently fibroin, by solution processing techniques. These forms include continuous filaments, pulp-like fibers (fibrids) and films. He has developed new solvent systems for cellulose, chitosan and fibroin. Presently, he is focused on the decontamination of chitosan, to allow its use for internal medical applications, such as an implantable hemostat, to control bleeding in laparoscopic surgeries.
