PhD, Biogeochemistry, Moscow State University, 1986
My research interests include the development of new techniques for AMS sample preparation, measurement and data analysis; the development of the AMS techniques for radiocarbon dating of ultra-small samples; the applications of carbon isotope measurment techniques to soil dynamics and global carbon cycle studies; the application of the radiocarbon method for analysis of biofuels and mixed biobased products; and the dating of tree rings for improvement of the calibration curve for the Southern Hemisphere.
