Education and Career track

I am a classically trained igneous petrologist currently based in the Department of Earth and Atmospheric Sciences at Cornell University. My research integrates the chemical composition of magmatic rocks, their constituent minerals, and mineral-hosted melt and fluid inclusions to investigate key processes in magmatic systems, including: (1) magma generation at depth; (2) magma evolution during ascent through the Earth’s crust; and (3) magma eruption to the Earth’s surface (volcanic activity).

I received my Diploma (Master of Science equivalent) in Geology from Moscow State University (Russia), where I conducted my thesis research under the supervision of Dr. Alexey Yaroshevsky. Following graduation, I worked for several years as a researcher at the Institute of Volcanology and Seismology in Kamchatka, Russia, studying active volcanoes in collaboration with Dr. Alexey Ozerov. During this period, I completed two international internships aimed at advancing my analytical skills: one at the University of Alaska Fairbanks, with Dr. John Eichelberger, and another at the University of Tasmania, with Dr. Leonid Danyushevsky.

In 2016, I received my Ph.D. in Geological Sciences from Rutgers University (New Brunswick, New Jersey), where I conducted research under the supervision of Dr. Claude Herzberg. My doctoral work focused on the trace element composition of olivine in mafic magmas, using it as a proxy to reconstruct magma chemistry, infer its origin and evolutionary conditions, and assess the degree of hydration in primitive magmas across diverse tectonic settings. This research led to three peer-reviewed publications: Levin et al. (2014, Geology) – a collaborative seismological-petrological study constraining the magma feeding depth of Klyuchevskoy volcano (Kamchatka); Gavrilenko et al. (2016, Bulletin of Volcanology) – an investigation of how a caldera-forming eruption restructured the magmatic plumbing system at Gorely Volcano (Kamchatka); Gavrilenko et al. (2016, Journal of Petrology) – a study introducing a new calibration of Ca-in-olivine as a hygrometer for estimating magmatic water content.

From 2016 to 2019, I held a postdoctoral fellowship jointly at Washington University in St. Louis and the University of Nevada, Reno, where I investigated the role and behavior of magmatic volatiles through experimental petrology in collaboration with Drs. Michael Krawczynski and Philipp Ruprecht. This work led to several key publications. In Gavrilenko et al. (2019, American Mineralogist), we demonstrated experimentally that olivine-hosted melt inclusions may yield a biased record of maximum magmatic H₂O contents due to the quenchability limitations of superhydrous melts. In Goltz et al. (2020, Contributions to Mineralogy and Petrology), we presented the first petrological evidence for the existence of superhydrous arc magmas. Most recently, Gavrilenko et al. (2025, Contributions to Mineralogy and Petrology) evaluates the application of the Ca-in-olivine hygrometer to melt inclusion datasets, bridging independent hygrometric methods to improve volatile budget reconstructions.

From 2019 to 2020, I worked as a Senior Researcher at the Skolkovo Institute of Science and Technology (Moscow, Russia), where I conducted experimental studies on the diffusion rates of selected radionuclides through pore waters in crystalline rocks. This applied research was part of a national initiative to support the development of a future deep geological repository for radioactive waste in Russia. The findings were submitted as a technical report to the contracting agency and are currently being prepared for publication in the journal “Radioactive Waste”.

From 2020 to 2022, I was a postdoctoral researcher at Université Grenoble Alpes (France) in the research group of Dr. A. Sobolev. My work focused on improving the accuracy of petrological tools by investigating secondary fluorescence (SF) effects – an often-overlooked but significant source of analytical error in electron probe microanalysis (EPMA). Using both analytical and experimental approaches, I quantified how SF can affect trace and minor element measurements in minerals, with implications for commonly used geothermometers, hygrometers, and oxybarometers. This work led to two key publications: Gavrilenko et al. (2023, Chemical Geology), which quantifies SF effects on EPMA analyses of olivine grains embedded in basaltic glass, and Llovet et al. (2023, Microscopy and Microanalysis), which identifies a systematic depletion of Ni in olivine due to missing boundary fluorescence. These studies provide important methodological advances for EPMA users concerned with analytical accuracy in petrology and mineral chemistry.

Since September 2023 I have worked as a postdoc at the Department of Earth and Atmospheric Sciences at Cornell University. In the group of Dr. Esteban Gazel, I study melt and fluid inclusions hosted in olivine crystals to understand the nature of mafic Plinian volcanic eruptions, in particular their volatile regime as well as the depth of magma supply and the magma ascent rates during such catastrophic eruptions.

I have done field-work on such volcanoes as Tolbachik, Klyuchevskoy, Bezymyanny, Shiveluch, Gorely, Mutnovsky, Karymsky in Kamchatka, Russia; Mount Shasta, California; Mount St. Helens, Washington; Etna in Sicily, Italy; Villarrica and Llaima, Chile. I have done analytical work at Université Grenoble Alpes (France), the Vernadsky Institute of Geochemistry and Analytical Chemistry (Moscow, Russia), the University of Alaska Fairbanks, the University of Tasmania (Hobart, Australia), and Rutgers University (New Brunswick, New Jersey). I have done experimental work at Washington University in St. Louis (Missouri), and the Vernadsky Institute of Geochemistry and Analytical Chemistry (Moscow, Russia).
