Our research program applies protein engineering technologies to develop physiological molecular targeting agents for molecular diagnostics and targeted therapy, with a focus on oncology and infectious disease. We balance (1) fundamental study of molecular evolution and protein biophysics, which empowers our protein engineering efforts; and (2) application of these advances to develop non-invasive diagnostics and therapeutics for clinical challenges in oncology and infectious disease. Our research is highly interdisciplinary including scientists, engineers, and collaborators across Chemical Engineering and Materials Science, Biomedical Engineering, Pharmacology, Chemistry, Oncology, Physiology, Medicinal Chemistry, Radiology, and more. We appreciate the support of the National Institutes of Health, the American Cancer Society, the University of Minnesota, and biotechnology partners.
