    Current Research and Scholarly InterestsResearch in our group explores the boundaries of modern organic synthesis to enable the more rapid creation of the highest molecular complexity in a predictable and controllable fashion. We are particularly inspired by natural products not only because of their importance as synthetic targets but also due to their ability to serve as invaluable identifiers of unanswered scientific questions.

    One major focus of our research is selective halogenation of organic molecules. Dihalogenation and halofunctionalization encompass some of the most fundamental transformations in our field, yet methods capable of accessing relevant halogenated motifs in a chemo-, regio-, and enantioselective fashion are lacking.

    We are also interested in the practical total synthesis of natural products for which there is true impetus for their construction due to unanswered chemical, medicinal, biological, or biophysical questions. We are specifically engaged in the construction of unusual lipids with unanswered questions regarding their physical properties and for which synthesis offers a unique opportunity for study.

  • Leah B. Bushin

    Leah B. Bushin

    Assistant Professor of Chemistry

    BioLeah Bushin is a chemical biologist and natural products chemist working at the interface of primary and secondary metabolism and leverages these insights to discover and produce novel natural products.

    The Bushin research group will investigate novel metabolic pathways, enzymes, and bioactive molecules across all kingdoms of life, intending to repurpose them to address challenges in human health and environmental sustainability. Current efforts will primarily center on developing strategies for the efficient microbial production of compounds and materials at scale, as well as high-throughput approaches for engineering enzymes to perform synthetic reactions. More broadly, as the group designs and refines bioproduction platforms, they hope to deepen their fundamental understanding of cellular metabolism. With genome sequencing revealing an immense reservoir of untapped biosynthetic potential, their work aims to uncover and harness nature’s chemical diversity for drug discovery and synthetic derivatization.

    Lynette Cegelski

    Monroe E. Spaght Professor of Chemistry and Professor, by courtesy, of Chemical Engineering

    Current Research and Scholarly InterestsResearch in the Cegelski laboratory is driven by the need to uncover and define the chemistry that underlies outstanding challenges in human health, the environment, and sustainability. Beyond discovery, we use chemistry as a tool to innovate and create solutions to these pressing problems. The laboratory is highly interdisciplinary, designing experimental approaches to understand how complex biological systems are built, organized, and controlled, and then perturb and influence assembly processes. The lab develops new methods and uniquely leverages: (1) small molecules in new biochemical assay development, chemical genetics approaches, and therapeutic discovery in infectious diseases, (2) fluorescence and electron microscopy coupled to analytical HPLC, mass spectrometry, and complementary biochemical techniques, and (3) spectroscopy, particularly solid-state NMR, to uncover new “dark matter” and define chemistry in insoluble, heterogeneous and complex assemblies relevant to human health, plants, and the ocean.

    Long-standing efforts in the laboratory focus on defining mechanisms underlying bacterial biofilm formation and identifying new antibiotic and anti-virulence strategies, including advancing therapeutic candidates for the most difficult-to-treat infections. Through these efforts, we uncovered a new chemical structure in nature: phosphoethanolamine (pEtN) cellulose. Cellulose is the most abundant biopolymer on earth and this discovery provided the first experimental validation of a naturally produced chemically modified cellulose. We are developing alternatively modified celluloses and polysaccharides and advancing new solutions for ecofriendly, sustainably sourced, and recyclable materials. Collectively, our projects span disciplines from molecular structure and assembly chemistry to living microbial communities and natural marine systems, while aiming to translate fundamental discoveries into therapeutic and materials solutions.
