Daniel Rohde, B.S.
Lab Manager / Clinical Research Coordinator / Research Assistant
Daniel Rohde is a prospective medical student and Bay Area native who has been working in the Orthopaedic Trauma Institute’s Digital Science Lab (DSL) since August 2023 after pivoting out of Technology Consulting with Deloitte. Daniel’s undergraduate experience at Harvey Mudd––earning a B.S. in Engineering––set him up well for his transition to the DSL, where he has been able to use that background while coordinating clinical studies and working with the resulting data. From setting up data collection devices to enrolling patients in studies to analyzing large datasets to applying for grants, Daniel has truly been involved in all phases of the research process. His work primarily focuses on post-operative pain and acute compartment syndrome and spans the realms of clinical and non-clinical studies and experiments. Daniel hopes to begin medical school in the Fall of 2026 and is excited by the prospect of a career as a physician. -

Dana Hazem, B.S.
Research Fellow, Digital Science Laboratory
Dana Hazem is a third-year medical student at the Geisel School of Medicine at Dartmouth College and a Bay Area native. As a Research Fellow with the Marmor Digital Science Laboratory at the UCSF Orthopaedic Trauma Institute, she contributes to multiple projects spanning clinical, cadaveric, and biomechanical research. Her work focuses on diagnostic innovation and clinical outcomes in acute compartment syndrome, the application of wearable technologies to enhance patient recovery, and the optimization of pain assessment and management strategies for orthopaedic patients. She values the multidisciplinary nature of her research, which fosters collaboration across diverse domains within the Orthopaedic Trauma Institute. Dana aims to become an orthopaedic surgeon committed to integrating evidence-based research into clinical practice and medical education to advance musculoskeletal health and improve patient outcomes.
