Volkan Sevilgen, CTO and cofounder, leads Temblor’s scientific programming and technology development. Volkan received an M.Sc. in Geophysical Engineering from Istanbul Technical University (ITU) in 2006 following a B.Sc. from ITU in 2003. He worked at the USGS, Menlo Park between 2006 – 2014, where he co-authored, developed and taught the Coulomb 3 earthquake stress and deformation software, and managed a four-year probabilistic seismic hazard assessment for the Balkan countries funded by USAID’s Office of Foreign Disaster Assistance. His studies on earthquake hazard and Coulomb stress interaction were published by Nature, the Proceedings of the National Academy of Sciences, and other distinguished geophysics and seismology journals. He is a member of AGU and the EERI Northern California Chapter. He is nominated for a Director position on the EERI Northern California Chapter Board for 2019-2020.
