My current research interests focus on understanding the relationship between crystal structure and magnetic properties of complex transition metal oxides (ferrites, manganites, cobaltites). Particular attention is paid to the study of temperature- and chemical pressure-driven structural and magnetic phase transitions in multiferroic and magnetoresistive oxide materials.
