Personal Information

I am Ali Ozgun Konca. Currently, I am a staff  researcher working at Caltech Seismo Lab.I got my PhD in Geophysics from Caltech in March 2008. I had my primary, secondary and high school education in Izmit, Turkey. Afterwards, I lived in Istanbul and studied physics at Koc University.   After I had my BS  majoring in physics at Koc University, I came to California Institute of Technology to study  geophysics.  I am a graduate student at Geological and Planetary Sciences.

 
Currently, I am working with Don Helmberger and Jean-Philippe Avouac on detailed earthquake rupture characteristics. Our study focuses on using multiple datasets (seismic and geodetic) to study large earthquakes. We utilize strong motion, to body waves, and surface waves and normal modes, as well as surface offsets, GPS and InSAR measurements of coseismic slip.

My interests include earthquake physics, long term and short term behavior of faults, strong-motion seismology, geodesy, inversion methods.
