- Ph.D., 2001, Texas A&M University, College Station, TX.

- M.Sc., 1998, Saint-Petersburg State University, Saint-Petersburg, Russia.

- B.Sc., 1996, Saint-Petersburg State University, Saint-Petersburg, Russia.



My research interests are in exploration geoscience, petroleum geochemistry, basin modelling and geological emissions of methane (mud volcanoes, seeps). I study conventional as well as unconventional oil&gas resources (shale gas/oil, coal bed methane, gas hydrates). I enjoy working at the intersection of geology with other disciplines such as chemistry, microbiology, statistics, engineering, economics, psychology and behavioral sciences.
