• Chemical tools to track how glycans change spatiotemporally during cell metabolism and signaling
• Biochemical studies to discover and predict functional effects of protein glycosylation
• Medicinal chemistry to inhibit metabolic risk factors in tumorigenic pathways

All cells use sugar, but a consequence of unbalanced sugar usage is disease through hexosamine sugar signaling pathways including glucosamines. To precisely define the roles of hexosamine sugar-driven effects, the Fehl Group designs chemical tools sensitive for live-cell applications, for example our light-controlled photosugars and our cell compartment-specific "GlycoID" labeling strategy. We apply chemical biology tools at the interface of metabolism disease and cancer pathways to discover new roles for glucose-driven events in cells and disease. A key target area is determining the mechanisms and potential treatment strategies for cancers that have elevated risk in patients with hyperglycemia.

Developing and utilizing highly selective chemical reactions that are able to occur in living cells to track sugar signaling motifs in disease states characterized by altered sugar metabolism

Dr. Charlie Fehl is a synthetic chemical biologist. His training--spanning the Atlantic ocean at times (University of Michigan / University of Kansas / Universität Regensburg (Germany)/Oxford University (United Kingdom)) – focused on chemical techniques in catalyst design, photochemistry and biocatalysis. These were applied to solve problems in drug design, protein synthesis + modification, epigenetic protein-protein interactions, and understanding complex enzymatic networks. Researchers in the Fehl Lab develop selective chemical and biochemical tools to unravel and treat complex problems in disease biology.
