Research Statement

Research in our lab focuses on understanding the role of glycans implicated in human health and disease.  Glycans (complex carbohydrates) are information-rich biopolymers critical to many biological processes, and act as major modes of communication and protection across organisms.  For example, different cancers exhibit carcinoma-specific aberrant glycosylation, bacterial and viral surface glycans serve as molecular loci for host cell adherence and infection, and proper cell differentiation and development relies on exquisite control of glycosaminoglycan sulfation patterns.  Despite this broad importance across biology, our current understanding of glycan function is limited compared to other biomolecules.  Unlike DNA, RNA, and proteins, our means of making and detecting these carbohydrate biomolecules in chemically precise fashions is severely lacking.  

To tackle these limitations, our group leverages techniques across chemistry, molecular biology, and engineering to develop novel tools for the investigation of glycans.  Utilizing a semi-automated directed evolution approach, we generate protein probes to specifically detect glycan epitopes.  Engineering plug-and-play flow reactors, we precisely synthesize glycan epitopes for use as both reagents and therapeutics.  Leveraging the base-pair specificity of DNA, we synthesize nanostructured glycoconjugate mimetics towards vaccine development and understanding mechanisms of infection.

Students in our lab will receive training in chemical biology, synthetic carbohydrate chemistry, enzyme biochemistry, microfluidics, biological nanotechnology, and respective state-of-the art characterization methods.  Students will also have the opportunity to explore biological applications of their work in cancer biology, microbiology and immunology.  The interdisciplinary nature of our group’s work continually seeks diverse students and researchers from various backgrounds
