My research interests are in bioinorganic chemistry and metallobiochemistry with an emphasis on elucidating roles of metal ions in catalysis by metalloenzymes, as well as processes by which microbes acquire metal ions they need to grow. We are currently focusing on the biosynthesis of siderophores in regards to microbial iron acquisition, with a focus on chirality in biosynthesis and chirality of the Fe(III)-siderophores; the role of haloperoxidases in disruption of microbial quorum sensing, as well as in cryptic halogenation reactions; the design of catechol compounds for wet adhesion; and the role of microbial peroxidases in lignin disassembly.
My research is on the structural elucidation of novel siderophores found through genome mining, and on studying the enzymatic mechanism by which marine bacteria secrete amphiphilic siderophores
My research focuses on predicting and characterizing siderophores with unusual characteristics through a genome mining approach.
My work explores the form-function relationship of iterative non-ribosomal peptide synthetases (NRPSs) involved in siderophore biosynthesis through cloning and site-directed mutagenesis. I am also isolating and characterizing bacterial siderophores predicted through genome mining techniques.
My work focuses on the isolation and structural characterization of bacterial siderophores predicted using genome mining techniques. I am interested in bioinformatics, NRPS-based biosynthesis, the evolution of siderophores.
I have worked as an undergraduate researcher in Dr. Butler’s lab for two full years and am currently attending my final year to earn a B.S. in biochemistry through the chemistry department at UCSB. My projects have included synthesizing derivatives of siderophores for wet adhesion purposes and conducting genomic studies to determine the genes responsible for siderophore production in bacteria. I hope to continue research after graduating and plan to attend graduate school after enjoying a year off of hiking and traveling.

Robert is an organic chemist in a bioinorganic laboratory. His research has focused on structure elucidation of siderophores and on the synthesis of siderophore analogues as small molecule models to further understand mussel foot protein adhesion on wet surfaces. He also enjoys talking in the third person apparently.
I’m interested in understanding how mussel foot proteins adhere to surfaces underwater and how to apply what we learn to synthetic adhesives. I synthesize small molecule models of mussel foot proteins to understand the role of lysine in adhesion. Additionally, I’m tracking oxidation kinetics of modified catechol in an effort to promote adhesion at physiologically relevant conditions.
