Prof. R. Gross

Research in the laboratory of Dr. Gross encompasses a wide variety of projects directed toward development of new enzyme and chemo-enzymatic strategies and methods for the synthesis of polymers for a wide variety of applications. Chemists, biochemists, microbiologists, materials scientists, engineers, physicists and clinicians work in teams on projects ranging from enzymatic and chemo-enzymatic routes to monomers, macromers, polymers and bioactive molecules. Novel enzyme engineering techniques and methods for enzyme immobilization are used to develop efficient catalysts that function under practical conditions. From thesestudies our group is developing fundamental new knowledge in enzyme structure-activity relationships for polymer synthesis and degradation reactions as well as an understanding of critical design elements that stabilize and activate enzymes on surfaces and within macroporous resins
