At the USPTO, Bronwen examined applications in the gene expression art unit of the recombinant molecular and microbiology section. Representative technologies derived from this innovation include nucleic acids encoding transcription control elements, nucleic acid constructs and methods of nucleic acid mutation. Earlier, Bronwen prepared and prosecuted patent applications in performance fibers technology, including polyester tire cord and industrial polyamide fiber.
Before working in patent law, Bronwen was a scientist at the Institute of Molecular Biology at the University of Oregon and at the Massachusetts Institute of Technology. She researched protein-DNA interactions in model prokaryotic and eukaryotic systems and protein structure-function analyses. Bronwen is the author of nine articles published in a variety of scientific peer-reviewed journals.
