His research interests cover nanofluids, pool boiling, falling-film evaporation and condensation, two-phase flow, flow induced vibration, flow boiling and condensation for external and internal flows, heat transfer enhancement, heat exchangers, phase-change in microchannels and solar energy. Prof. Ribatski is Brazilian Delegate to the Assembly for International Heat Transfer Conferences since 2017. He is Associate Editor of the Experimental Thermal and Fluid Science and member of the Editorial board of International Journal of Multiphase Flow and International Journal of Microscale and Nanoscale Thermal and Fluid Transport. He is member and president of the Brazilian Society of Mechanical Sciences and Engineering. He is member of Assembly of World Conferences on Experimental Heat Transfer, Fluid Mechanics and Thermodynamics, Virtual Institute of Two-Phase Flow and Heat Transfer, Scientific Council of the International Centre for Heat and Mass Transfer (ICHMT), and corresponding member of The ICeM NEWSLETTER / The Japanese Society for Multiphase Flow. The Heat Transfer and Research Group at EESC-USP, under guidance of Prof. Ribatski, is recognized worldwide as one of leading groups in Brazil performing studies on two-phase flow and flow boiling. He has presented 8 keynote lectures and taken part in the scientific committee of several International Conferences. Dr. Ribatski has over 70 refereed journal publications, 6 book chapters, and over 100 refereed papers in conferences. (Source: Lattes Curriculum)
