Assistant Professor

Areas of Interest
Signal Transduction, PI3K-AKT signaling, chemical biology, protein-protein interactions, kinases, structural biology


Dr. Marsiglia received a BA in Music and BS in Biochemistry from SUNY Binghamton in 2013. He then earned his PhD in Chemistry at NYU using NMR spectroscopy to explore the activation mechanisms underlying pathogenic FGFR kinase domain mutations. During his postdoctoral work at the Icahn School of Medicine at Mount Sinai starting in 2019, Dr. Marsiglia developed a NanoBRET assay that helped to elucidate the mechanism of action for the MEK inhibitor, Trametinib. In 2022, Dr. Marsiglia joined the Department of Pharmacology and Toxicology at the University of Alabama at Birmingham as an Assistant Professor.

  • Research Interests

    My chemical biology focused lab provides a multidisciplinary training environment for students and postdocs where they learn how to develop compounds and study them in biological systems using a combination of cell culture, structural biology, and synthetic-based techniques. My lab specifically develops NanoBRET-based assays to profile novel small molecule inhibitors targeting AKT-binding partner complexes, and structural characterization of those interactions. Our goal is to understand what AKT-binding partner interactions are important for AKT inhibitor efficacy, and design new drugs to take advantage of those interactions.
