Research Interests

Our laboratory has three main areas of research: custom instrumentation for Fourier Transform Mass Spectrometry (FTMS), Nuclear Signaling and Natural Products. More specifically, our main interests lie in the enzymology of natural product biosynthesis, mass spectrometric-based studies of the "Histone Code," and development of Fourier Transform Mass Spectrometry (FTMS) for Top Down Proteomics (i.e. analyzing intact proteins directly; no proteases).

A core activity is measuring chemical modifications to proteins in both hypothesis-driven and discovery modes. Our pioneering efforts in "Top Down" proteomics involve fragmenting intact protein ions in the gas phase and developing custom bioinformatics to characterize unexpected post-translational modifications (PTMs) in methane-producing microbes, yeast, and human cancer cells. In both human cell biology and antibiotic biosynthesis, key proteins harbor over 20 PTMs that present a "code" of biological logic written in the language of protein modifications. We construct, automate, and apply custom mass spectrometry and algorithms to detect and decode this logic.
