The Walt lab has pioneered technologies that have improved our ability to analyze important biomolecules like proteins, nucleic acids, metabolites, enzymes, and extracellular vesicles. Our technologies, including Single Molecule Arrays, have allowed us to push the boundaries of high sensitivity biomarker detection. Today the lab is composed of an interdisciplinary team of passionate and motivated scientists and engineers, including chemists, biologists, biomedical engineers, computer scientists, and physicians who continue to develop new technologies while at the same time applying them to better understanding human disease. We apply our technologies primarily towards understanding and diagnosing diseases processes including cancer, infectious diseases and neurodegenerative diseases.
