Dr. Karastogianni Sophia has studied Chemistry at the Department of Chemistry of the Aristotle University of Thessaloniki with a degree in Physical, Analytical and Environmental Chemistry. She has attended during her studies but also afterwards a number of conferences and seminars related to the subject of her specialty. Her dissertation was carried out in the Physical Chemistry Laboratory on the subject of the Comparative Study of Linear Stability Analysis in the Time domain and in the Frequency domain and supervising Prof. M. Pagitsas.

She was awarded a PhD in Chemistry from the Department of Chemistry of the Aristotle University of Thessaloniki in the laboratory of Analytical Chemistry under the supervision of Prof. Girousi Stella. The subject of the dissertation and its related publications touch on the subject of electroanalysis and analytical chemistry in general. Electrochemical techniques were used to characterize the studied species, the electrochemical synthesis of new materials with the aim of modifying the electrode surface and the detection and identification of various species by developing electrochemical and (bio) sensors.

She has carried out postdoctoral research in the framework of the program “Scholarships of excellence of IKY postgraduate studies in Greece-SIEMENS Program” on the development of electrochemical sensors and DNA electrochemical sensors using modified with silver nanoparticles capped with natural dyes carbon paste electrode in the laboratory of Analytical Chemistry of Aristotle University and supervising Prof. Girousi Stella.

Nowadays she carries out postdoctoral research within the framework of the IKY Excellence Scholarship Program “Support for Postdoctoral Researchers – Second Cycle”, in the framework of the Act with code 5033021 of the OP. “Human Resources Development, Education and Lifelong Learning” (NSRF 2014-2020) on ” Development of bio-imprinted electrochemical sensors for the detection of biomarkers of the disease with the smell of maple syrup (MSUD) in modified electrodes with metal nanoparticles capped with saffron ” in the laboratory of analytical chemistry of the Department of Chemistry, Aristotle University and supervising Prof. Girousi Stella.
