David W. Roberts

David W. Roberts is an Adjunct Professor of Engineering and holds dual professorships in Surgery (Neurosurgery) and Neurology at the Geisel School of Medicine at Dartmouth College. He specializes in stereotactic and functional neurosurgery, cancer neurosurgery, and intraoperative imaging technologies. His work focuses on advancing image-guidance systems and computational modeling for neurosurgical applications.

Education includes an AB from Princeton University (1972), MD from Dartmouth Medical School (1975), and MA from Oxford University (1978). He is actively involved in professional organizations such as the American Academy of Neurological Surgery and serves on editorial boards for journals like Stereotactic and Functional Neurosurgery.

His research emphasizes improving glioma resection through fluorescence imaging and real-time surgical guidance. Notable projects include preoperative image updating for tumor resection and quantitative analysis of protoporphyrin IX in gliomas. Recent publications (2011–2012) explore technical advancements in fluorescence-guided surgery and correlations between imaging biomarkers and histopathological malignancy.

Roberts has been instrumental in clinical trials evaluating 5-aminolevulinic acid (5-ALA) for glioblastoma treatment and contributed to FDA-approved imaging technologies for surgical guidance. His work bridges engineering innovations with clinical neurosurgical practice, enhancing precision in tumor resection and patient outcomes.
