Brad Pierce joined the faculty of the department of Chemistry & Biochemistry at the University of Texas at Arlington in 2008. The breadth of research efforts conducted in the Pierce group follows an interdisciplinary approach; providing training in methods and instrumentation typically outside traditional divisional boundaries within chemistry departments (organic, inorganic, analytical, biochemistry, and physical). Research in the Pierce group employs modern biophysical and bioinorganic techniques to investigate mechanisms of metalloenzyme function and regulation. The scope of research in our group is fairly ambitious in that it spans work at the genetic level (PCR cloning, expression vector design, and site directed mutagenesis) all the way up to spectroscopic characterization (UV-visible, CD, EPR, and Mössbauer) of purified enzyme systems. In particular, the Pierce group specializes in the use of dual-mode EPR spectroscopy which, in combination with spectroscopic simulations, is a highly sensitive method for probing the active site electronic structure of metalloenzymes.
In addition to this research, Dr. Pierce is a dedicated instructor. Indeed, in 2012 Dr. Pierce was awarded the President’s Award for Excellence in Teaching for an untenured professor. He currently offers courses in both biophysical chemistry and inorganic chemistry at the graduate and undergraduate level. Prior to his appointment at UT-Arlington, Dr. Pierce was an NIH postdoctoral researcher in the lab of Professor Brian Fox (Department of Biochemistry) at the University of Wisconsin. Within the Fox lab, his work focused on the mechanistic investigation of non-heme iron metalloproteins and the protein-protein interactions which influence their O2- and substrate reactivity. In 2003, Dr. Pierce received his Doctorate in Chemistry from Carnegie Mellon University under the supervision of Professor Michael P. Hendrich. His work focused on the use of dual-mode and multifrequency electron paramagnetic resonance (EPR) spectroscopy to characterize transition metal model complexes and metalloproteins.
Brad Pierce received his B.S in Chemistry with a minor in Biology from California State University at Chico. Following graduation, Dr. Pierce worked for several years as research associate within the drug delivery R&D division at Matrix Pharmaceuticals in Fremont, CA. At Matrix he assisted Dr. Kathy Roskos on the development and characterization of gel-based cisplatin/epinephrine antineoplastic formulations. Dr. Pierce currently lives in Fort Worth with his wife Christy.
研究领域
Fundamental life processes (respiration, photosynthesis, and replication) frequently involve transition metal ions or elements outside the traditional purview of biochemistry. As a result, ground breaking work relevant to chemical biology lies at the interface of (or crosses) traditional divisional boundaries in chemistry. The scope of research conducted by the Pierce group embraces this interdisciplinary approach; we employ modern biophysical and bioinorganic techniques to investigate mechanisms of metalloenzyme function and regulation. This range of effort is fairly ambitious in that it spans work at the genetic level (PCR cloning, vector design/expression, and site directed mutagenesis) all the way up to spectroscopic characterization (UV-visible, CD, EPR, and Mössbauer) of purified enzymes.
Specific topics of interest to our group focus on understanding mechanisms of biochemical thiol-oxidation and the interplay between dysfunction in sulfur metabolism and human neurodegenerative disease states (Alzheimer’s, autism, and Parkinson’s). Enzymes involved in sulfur-oxidation and transfer are increasingly being recognized as potential drug targets for development of antimicrobials, therapies for cancer, and inflammatory disease.
An additional area of focus involves the study of metalloenzymes involved in the post-transcriptional modifications of transfer RNA (tRNA). In many instances, the physiologic role of such modifications is unclear; however, several examples have been identified to suggest that the presence of modified nucleosides in tRNA can impact aminoacyl-tRNA selection, decrease translational frame-shifting, regulate central metabolism, as well as initiate genes involved in bacterial virulence.
