Pavel has graduated from the Novosibirsk State University in Novosibirsk, Russia in 1992 with Masters of Science degree in Geochemistry. He worked as an assistant researcher, then research scientist at the the Laboratory of Rare Earth Elements Geochemistry and Ecogeochemistry since 1989. Among the research projects he participated in are studies of the regions adjacent to the Semipalatinsk Nuclear Test Site and other regions of Altay, the area north of Kazakhstan. During these expeditions extensive sampling and analyses of radioactive and heavy metal contamination were carried out and conclusions were made regarding possible impacts on the human health.
In 1997 Pavel received his Ph. D. degree in Geological Sciences from the University of South Carolina. During his graduate studies Pavel also assisted and later personally operated an Optima mass spectrometer, carrying out analyses of carbon and nitrogen isotopic ratios in a wide variety of substances. Main target of Pavel's studies was the reconstruction of the paleoclimatological history of Siberia using sedimentary records from Lake Baikal as a proxy. He participated in several expeditions to Lake Baikal to collect samples used for these studies.
In 1997, Pavel joined the NOAH research group at the NOAA-CMDL. Attracted by the challenge of the new field in science, Pavel participated in several airborne science missions and successfully operated ACATS-IV during POLARIS, SOLVE and TROICA-7.
Pavel invested a lot of time in mastering IDL,
the Interactive Data Language from the Research Systems, Inc. This work resulted
in a new software package,
for chromatographic data analyses. This package allowed to decrease data
processing time by a factor of 10. During his work on HATSchrom Pavel wrote a
number of useful IDL library routines
graphics interfaces and utility functions for global variable creation and
main level exporting. A subset of Pavel's IDL library is
