I am a geophysicist with a background in mathematics and statistics and my research interests are: rock physics, seismic reservoir characterization, inverse problems, geostatistics, and time-lapse reservoir modeling. These are the topics that are the present focus of my research:

  1. Bayesian inversion of time-lapse seismic data for reservoir property estimation,
  2. Velocity-pressure relation in clastic reservoirs,
  3. Joint inversion of EM and seismic data,
  4. Seismic history matching.


The Geology & Geophysics Department offers a wide range of courses in geophysics. In the coming semesters I will be teaching Rock Physics and Reservoir Modeling.
