Dr. Elizaveta Kovaleva 

Dr. Elizaveta Kovaleva has completed an MSc degree at the Department of Petrology, Faculty of Geology at the Lomonosov Moscow State University, Russia, under the supervision of the late Prof. Leonid L. Perchuk. The research was dedicated to folding, granitization, and charnockitization processes in Archaean granulites of the Limpopo Granulite Belt, South Africa. After obtaining a degree, she was working as a researcher in the Laboratory of Lithosphere in the Institute of Experimental Mineralogy, Russian Academy of Sciences, in Chernogolovka, Russia, under the supervision of Prof. Oleg G. Safonov. There, she was conducting experimental modeling of metamorphic and metasomatic reactions in granitic gneisses, using the high-pressure-temperature apparatus.

In 2012, she joined the international doctoral school “DOGMA” (Deformation of Geological Materials: Mechanical-chemical feedback and the coupling across scales) at the Department of Lithospheric Research in the University of Vienna, Austria, starting a Ph.D. project titled “Rejuvenation effects during plastic deformation; Microchemistry and microstructure/texture of accessory minerals and the effect of deformation on the retention of radiogenic isotopes” under a supervision of Prof. Urs Kloetzli. During her doctoral studies, Elizaveta attended a workshop “Texture analysis with MTEX emphasizing EBSD data analysis’’, conducted by David Mainprice in the Technical University in Freiberg, Germany; and a Summer School IK “DOGMA” on structural geology organized by the University of Vienna in Greece, Serifos.

From 2015 to 2019, she was a postdoctoral fellow at the Department of Geology at the University of the Free State (UFS), South Africa. Her research was focused on the investigation of crystal-plastic and shock deformation in zircon from the impacted rocks of the Vredefort impact structure, as well as on the geochemistry and petrography of impact-generated melts. During this time period, she received three grants from the National Research Foundation (NRF): “Knowledge Interchange and Collaboration – Africa interaction 2015/2016”,  “Freestanding Postdoctoral Fellowship (local) 2017/2018” and “Knowledge Interchange and Collaboration – Local Travel 2018”.

Elizaveta is appointed permanently as a Senior Lecturer (Mineralogy, Plate Tectonics) at the Department of Geology, UFS. Elizaveta is a coordinator of the interdisciplinary research group GRAVITAS (“Geological Research and Analysis of Vredefort Impact with Timely Anthropological Studies”).
