Volkan Sevilgen, M.Sc. — cofounder and CTO
volkan@temblor.net
Volkan leads Temblor’s scientific programming and technology development. He received an M.Sc. in Geophysics from Istanbul Technical University in 2006, and then worked at the USGS with Ross until 2014, where he helped to develop and teach the Coulomb 3.0 earthquake stress and deformation software, and also managed a four-year probabilistic seismic hazard assessment for the Balkan countries funded by USAID’s Office of Foreign Disaster Assistance. Sevilgen’s 2012 study, ‘Stress imparted by the great 2004 Sumatra earthquake shut down transforms and activated rifts up to 400 km away in the Andaman Sea,’ appeared in the Proceedings of the National Academy of Sciences.

Ross S. Stein, Ph.D.cofounder and CEO
ross@temblor.net
Ross S. Stein is Temblor CEO and cofounder, Adjunct Professor of Geophysics at Stanford University, USGS Scientist Emeritus, President of the Tectonophysics section of the American Geophysical Union, and 2017-2018 International Distinguished Lecturer of the Geological Society of America. A Fellow of the American Geophysical Union and Geological Society of America, Stein received the 2012 Gilbert F. White Natural Hazards Award from AGU, gave a 2012 TEDx talk, ‘Defeating Earthquakes,’ and received the 2000 Eugene M. Shoemaker Distinguished Achievement Award of the USGS. In 2003, the Science Citation Index reported that Stein was the second most cited author in earthquake science during the preceding decade; he was tenth most cited during 1900-2010. Stein frequently brings insights to the public media interviews, TEDx and public talks, and in IMAX and Discovery Channel films. In 2010, Stein cofounded the Global Earthquake Model (GEM Foundation), and chaired its Science Board until 2015. Stein is a member of the Resilient America Roundtable of the National Academy of Sciences, and the Natural Catastrophe Advisory Council of Zurich Insurance.

David-Jacobson

David Jacobson, M.Sc.GIS Analyst
David has a M.Sc. in Geology from the University of Canterbury, in Christchurch, New Zealand. Christchurch has become the world epicenter for the consequences of liquefaction, making David the perfect person to scour the United States for liquefaction, landslide, and fault data for the Temblor app. His GIS and field geology skills only increase his value to the team. David received Academic Distinction and the Albert Ripley Leeds Memorial Prize in Geology at Whitman College, where he received his B.A., and he is a recipient of an Earthquake Commission Scholarship and a Mason Trust Scholarship at the University of Canterbury. David enjoys backpacking, distance running, and is an avid ultimate frisbee player and was a two-time national champion while in New Zealand.

 


Gabe-Lotto
Gabriel Lotto, MS Tsunami and Flood R&D
Gabriel received his MS in Computational and Mathematical Engineering from Stanford University 2013; his thesis was published as Lotto and Dunham (2015), “High-order finite difference modeling of tsunami generation in a compressible ocean from offshore earthquakes.” He is now a PhD candidate in Geophysics at Stanford, where his research focuses on coupled modeling of earthquakes and tsunamis. Gabriel is also cofounder of Fog City Singers, a barbershop chorus based in San Francisco, and sings in a competitive barbershop quartet.

 


jessie2
Jessica O’SullivanRetrofit analyst and Social Media
Jessie got her Bachelor’s degree at Quest University Canada (B.C.) studying how geology shapes cities, a focus that makes her a perfect complement to our team. She is currently enhancing Temblor’s social media presence, and analyzing how our website and app could be more lucid and intuitive. She is also focusing on how Temblor can inspire people to retrofit their homes to better survive earthquakes, working both with retrofit contractors and homeowners. She spent several months working on a tea plantation near Kyoto, Japan, and has served as a hotel and conference concierge during her college summers.

Geoffrey ElyComputational Seismologist
Geoff has a Ph.D. in Earth Sciences from U.C. San Diego, and has had Post-Doctoral Fellowships at USC and Argonne National Laboratory. He is a scientific software developer who has worked on earthquake rupture dynamics, wave propagation, and ground motion using numerical simulation via high-performance computing, with a keen eye for visualization. His skills include parallel-processing with message-passing and multi-threading, performance tuning in assembly language, numerical methods, signal processing, cartography and graphics programming.

 


Gitanjali Bhattacharjee zoom
Gitanjali BhattacharjeeSeismic Engineer and UI/UX Designer
Gitanjali is a M.Sc. candidate in structural engineering at Stanford University. Her research focuses on probabilistic hazard analysis, disaster risk and impact, and human-computer interaction. She is contributing to Temblor’s hazard and risk mapping capabilities and its UI/UX design. Gitanjali graduated from the University of Texas at Austin with special honors in architectural engineering (B.S.) and liberal arts (B.A.). In her free time, she tries to get out of her comfort zone, which currently involves studying printmaking, camping, and blogging at gbhattacharjee.com.
