Our environment is shaped by the reactions that occur at the interface between the hydrosphere, atmosphere, and silicate Earth. My endeavors involve developing novel approaches in isotope geochemistry to study how environmental conditions are imprinted in the rock record through such reactions. I like to think about the following questions: What is the connection between the evolution of continental crust and the long-term changes in climate? What are the feedbacks between seawater dissolved content, atmospheric chemistry and the rock cycle? What are the formations, minerals and isotope systems that offer proxies for unreacted seawater or local precipitation?

My work focuses on O-isotope geochemistry including O-17, Precambrian geology and water-rock interaction. I routinely measure δD, δ17O and δ18O in sedimentary, igneous, and hydrothermally altered rocks to learn something new about the environment at the time. Normally, I like to study old (Precambrian) rocks because there are fewer reliable environmental proxies, thus, the world is less constrained, and the approaches must be creative. I also enjoy studying modern environments, be it altered oceanic crust, hydrothermal vent fluids or a geothermal plant.


As a lead researcher, I have targeted:

On-going projects include using Secondary Ion Probe measurements of stable isotopes to answer questions in hydrothermal reactivity of seawater in oceanic crust, diagenetic maturation of cherts, triple O isotope geochemistry of terrestrial rocks, rock-water exchange experiments.


I did my undergraduate degree at the Russian State Geological Prospecting University in Moscow studying general and economic geology with specific focus on geochemistry and mineralogy of ore deposits. My PhD was done at the University of Oregon under supervision of Ilya Bindeman. For my postdoctoral research, I am investigating Archean sedimentary records at the SwissSIMS laboratory of the University of Lausanne. The analytical endeavors include laser fluorination, high-precision gas source mass spectrometery and secondary ion probe measurements. My field work has taken me to Russian Karelia, Scottish Highlands and Iceland. See my CV.

A few projects conducted in my spare time are listed below:
Adularia: A web-based application that calculates mineral formula based on EMPA analyses
A Shiny app that visualizes elemental maps in the Vetreny belt sample of hydrothermally altered komatiitic basalt (takes a while to load).
Oxygen isotope cheahsheet is a pdf/ppt file with oxygen isotope delta-notations, ranges, standardizations, fractionation factors, meteoric water cycle, etc.
