Yury Sigal

Light Microscopy Specialist
Biophotonics Core

As a Light Microscopy Specialist in the Biophotonics Core Facility at the Salk Institute, Yury Sigal's primary responsibility is the training of new users in cutting-edge microscopy and imaging techniques. Yury is a Cell Biologist by doctoral training. In his Ph.D. he focused on the role lipid phosphatases played in LPA signaling and in the regulation of cellular filopodia. After completing his doctoral studies he moved to the Genomics Institute of the Novartis Research Foundation (GNF) in San Diego where he worked in the Bio-Imaging Core Facility. There his research was directed at using live cell and high-throughput imaging technologies to study the role of RNA that are associated with the regulation of mitotic processes. This involved developing a novel fluorescence assay based around GFP complementation to study the dynamics of cellular RNA.
