Dr. Sergienko specializes in corrosion and electrochemistry, water chemistry and treatment, and advanced characterization methods, bringing these together to tackle complex technical and environmental challenges. She is skilled in electrochemical techniques such as electrochemical impedance spectroscopy (EIS), potentiodynamic polarization, and cyclic voltammetry, as well as in a broad range of analytical methods including X-ray diffraction (XRD), scanning electron microscopy with energy-dispersive spectroscopy (SEM/EDS), X-ray photoelectron spectroscopy (XPS), Raman and FT-IR spectroscopy, X-ray absorption spectroscopy (XAS), UV — Vis spectroscopy, high-performance liquid chromatography (HPLC), and ion chromatography (IC).
Before joining Ģtv, Dr. Sergienko completed her Ph.D. in Environmental Engineering at the Catalan Institute for Water Research (ICRA) in Spain, where she investigated electrochemical processes for prevention of sulfide induced corrosion in anaerobic systems. She then joined the University of California, Berkeley, as a postdoctoral researcher, where she conducted corrosion assessments of gas diffusion electrodes, studied cathodic mineral scaling in water treatment systems, and evaluated the performance of advanced oxidation processes for contaminant removal. Her experience also includes supporting scale-up of electrochemical reactors, assessing electrode performance under realistic operating conditions, and collaborating with cross-disciplinary teams to solve treatment and corrosion challenges.
