University of California San Francisco – Holographic Imaging Cytometry Center of Excellence

University of California, San Francisco (UCSF) and PHI have jointly created a regional Holographic Imaging Cytometry Center of Excellence headed by Dr. Robert Judson-Torres. Located at the UCSF Helen Diller Family Comprehensive Cancer Center, the Center’s activities focus on bringing the benefits of holographic cytometry and machine-learning to the UCSF research community, by providing education and technical support.

The recurring UCSF-PHI symposium serve as a forum for scientists who worldwide develop new therapies and diagnostic techniques for melanoma and other cancers.

“Holographic cytometry permits simultaneous quantification of cell division, death, senescence, and motility of adherent cells over long-term culture”

Judson's research interests focus on the networks of genes and environmental factors that stabilize cell states in adult mammalian organisms, and, conversely, the coordinated sets of destabilizing factors which can lead to tumorigenesis. He is also actively involved with exploring new models of scientific training, communication and publication, including experimenting with forums for post-publication peer review, reproducibility initiatives, and strategies for training the scientific workforce.

  • JoVe (video journal), 2018 | J Huang, P Guo and Marsha A. Moses

    The video and publication demonstrate how HoloMonitor is used to conduct time-lapse and labeling-free characterizations of angiogenic and non-angiogenic human osteosarcoma KHOS cells. A panel of cellular parameters, including cell morphology, proliferation, and motility, were quantitatively measured and analyzed using HoloMonitor.

    HoloMonitor was used to measure cell volume. Together with other methods the results identify DPN (deep penetrating nevus) as an intermediate melanocytic neoplasm, with a progression stage positioned between benign nevus and DPN-like melanoma.
