Dr. Gherhardt Ribatski, University of Sao Paulo, Brazil
Dr. Gherhardt Ribatski is Full Professor of Multiphase Flow and Heat Transfer at the São Carlos School of Engineering, University of São Paulo (USP), Brazil. He received his BS, MSc. and Doctoral Degrees in Mechanical Engineering from the University of São Paulo. He held postdoctoral positions at the University of Illinois at Urbana–Champaign, Swiss Federal Institute of Technology in Lausanne (EPFL) and Universidade da Coruña. His research interests cover pool boiling, falling-film evaporation and condensation, two-phase flows, flow induced vibration, flow boiling and condensation for external and internal flows, heat transfer enhancement, heat exchangers, phase-change in microchannels, IR thermography wastewater treatment and solar energy.
Prof. Ribatski is member of the Congress Committee of International Union of Theoretical and Applied Mechanics (IUTAM) and Brazilian Delegate to the Assembly for International Heat Transfer Conferences. 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). He was Director Secretary (2016-2017) and is member and President of the Brazilian Society of Mechanical Sciences and Engineering (2018-2021). He has served as coordinator of the CAPES (Coordination for the Improvement of Higher Education Personnel- Brazil) committee for evaluation of graduate programs in the areas of Mechanical, Mechatronics, Naval and Ocean, Aeronautical, Industrial and Petroleum Engineering. He is member of the area panel of Engineering of FAPESP (São Paulo Research Foundation – Brazil) and was Coordinator of the Graduate Program of Mechanical Engineering at São Carlos School of Engineering (EESC) of University of São Paulo (USP) from 2014 to 2019.

Dr. Prashant Valluri, University of Edinburgh, UK
Professor Prashant Valluri is a Professor of Fluid Dynamics and the Director of Chemical Engineering at the University of Edinburgh. He studied at Imperial College London where he finished his Doctoral Studies in Chemical Engineering in 2004. He chairs the UK Multiphase Flows and Transport Phenomena Special Interest Group (UK Fluids Network). He has expertise in numerical and theoretical techniques to study complex industrial multiphase flows. He co-developed the TPLS 3.0 open-source solver (https://sourceforge.net/projects/tpls/) that has yielded fundamental insights in applications including thermal management of microelectronics, pipeline flows, and post-combustion carbon capture. He is the PI/Coordinator of the recently awarded €1.7M five-continent (19 partners) EU SE ThermEnTrans Consortium (101236597) on phase-change based thermal management for Energy Transformative Technologies.
