Characterizing biogeochemical cycles that mediate the exchange of carbon among major reservoirs at the boundary of the hydrosphere and the lithosphere is the primary focus of my research. I am specialized in elucidating the effects of carbon exchange on biological systems (from organisms to ecosystems) and the ecological feedback mechanisms on the carbon cycle. I identify natural and/or anthropogenic environmental factors influencing rates of carbon exchange, fluxes, and organic matter transformation. To tackle these topics, I use stable and radiocarbon isotope approaches; and develop techniques to elucidate the effects of hydrodynamics and other environmental factors on elemental cycling and carbon fluxes.
Main contributions of my research have focused on the biogeochemistry and ecological ramifications of methane and dissolved organic carbon (DOC) in low-temperature aqueous systems. These efforts have resulted in a comprehensive ecosystem function model that integrates landscape-level biogeochemical and hydrological processes and quantifies the magnitude of a greenhouse gas sink in the karst subterranean estuary.

Ph.D.: Marine Biology. 2017. Texas A&M University at Galveston.
M.S.: Biology. 2009. Eötvös Loránd University, Budapest.
After receiving my Biology Diploma from Eötvös Loránd University (ELTE) in 2009, I worked for two years as an Ecologist on terrestrial ecosystems in Hungary. A Fulbright Scholarship then allowed me to expand my research to oceanography and biogeochemistry by pursuing a doctorate degree at Texas A&M University at Galveston, where I completed my Ph.D. in the Marine Biology Interdisciplinary Program in 2017. I am now a Postdoctoral Scholar in the Marine Chemistry & Geochemistry Department.
