Viviani Onishi is an Invited Assistant Professor at the Department of Mechanical Engineering of the University of Aveiro, and a Researcher at the Centre for Mechanical Technology and Automation of the University of Aveiro, Portugal. V.C. Onishi has obtained a Ph.D. in Chemical Engineering following her doctoral studies in the field of Process Systems Engineering (Synthesis, Design and Optimization of Energy Processes) at the State University of Maringá in Brazil (2014). She also holds Ph.D. Equivalences by the University of Alicante, Spain (2015), and University of Aveiro, Portugal (2017). V.C. Onishi has expertise in Computer-Aided Process Systems Engineering, specifically in the application of Mathematical Modelling and Optimization techniques (Deterministic and Stochastic Optimization, Multi-Objective Optimization, Multiperiod Optimization and Multilevel Optimization, Stochastic Chance-Constrained Fuzzy Programming); Optimization under Uncertainty and Risk Management; Energy, Environmental, and Cost Analyses; Eco-efficiency and Eco-design methods; Reliability and Flexibility Analyses; and, Life Cycle Assessment (LCA) techniques. Her research interests are mainly focused on the development of decision support tools for the optimal design and operation of advanced smart and renewable energy systems; advanced energy storage and conversion systems (thermal, hydrogen and methane energy); smart district heating and cooling systems; thermal-efficient building design; smart buildings design; decentralized energy production (combined heating, cooling and power plants); and, waste heat recovery alternatives (organic Rankine cycles). V.C. Onishi’s academic journey includes awarded fellowships and research contracts (9), teaching experience as Assistant Professor at the State University of Maringá (~4 years) and University of Aveiro (>1 year), supervising of master students (2) and undergraduate students (8), and academic degree jury participation (3). Her publication and citation track (over 45 publications, the vast majority as first/main author¿; h-index 10 – Scopus, h-index 11 – Google Scholar) includes 16 peer-reviewed articles on top-tier journals like Applied Energy (IF: 8.426), Energy Conversion and Management (IF: 7.181), Desalination (IF: 6.035), Journal of Cleaner Production (IF: 6.395), and Energy (IF: 5.537), to list but a few; 10 book chapters for Elsevier and Nature Springer; and, 19 papers on international conference proceedings. She is currently a Guest Editor of a Special Issue in the Journal Processes, and is serving as an Ad-Hoc Reviewer for over 30 international SCI-indexed renowned journals, such as Applied Energy, Energy Conversion and Management, Energy, International Journal of Hydrogen Energy, Applied Thermal Engineering, and Journal of Cleaner Production, among others. V.C. Onishi has also been involved in several high-profile national and international projects (13 projects in total) –supported by the European Union's Horizon 2020 Research and Innovation Programme, European Regional Development Fund (COMPETE 2020 Programme), FCT – Portuguese Foundation for Science and Technology and Regional Operational Program of the Center Region (CENTRO2020), Brazilian foment agencies (CNPq and CAPES), and Spanish Government– under different roles (Principal Investigator, Work Package Leader, and Team Member), contributing to the attainment of significant external research funding.
