About
The Research Group
At the heart of every scientific breakthrough lie curiosity, dedication, and collaboration. Here, at the Research Group in Microfluidic & Photoelectrocatalytic Engineering, we embody these principles to contribute with meaningful insights into the fields of photocatalysis, electrocatalysis, and microfluidics, with a special interest in developing sustainable decarbonization technologies.
As a research group rooted within a Jesuit institution and aligned with its ethos, we believe that scientific inquiry is not just a pursuit of knowledge but also a profound reflection of our commitment to the greater good. Inspired by Jesuit ideals, we aim not only for answers but for understanding and purpose, viewing each challenge as an opportunity to engage deeply with the world and harness science in the service of humanity.
With this mission, our team aspires to form a diverse ensemble of researchers, scholars, and innovators. Together, we explore complex challenges of nano-scale catalysis and how these innovative processes can be intensified using microstructured reaction spaces. We do so using an ab-initio approach, with computational chemical and fluid dynamics modeling, combined with practical, hands-on experimental developments, including new equipment design. We believe that the multidisciplinary arrangement between chemistry, materials science, and chemical engineering is key to making future technologies a reality for sustainable development.
Beyond research, we're dedicated to creating a learning and mentorship environment. Our group is proactive in integrating sustainability and innovation into our teaching assignments, using transdisciplinary and active learning methodologies that stimulate the development of important soft skills that help shaping individuals into not just outstanding professionals, but also compassionate human beings. We're also eager to expand our collaborations with institutions worldwide, host workshops, and offer research opportunities.
We invite you to explore our page, learn more about our current projects, and perhaps discover ways to collaborate or engage with us! Science is made of collective efforts, and every question, idea, or insight brings us one step closer to understanding the ever-evolving world of Chemical Engineering.
Welcome aboard, get in touch, and thank you for your interest in our research! :)

Dr. Ramos
About
Dr. Ramos, the head of the Group, is an Industrial Chemist whose research focuses on photocatalysis, computational chemistry and microfluidics. During his studies towards a Bachelor's degree from Goias State University in 2007, he explored Density Functional Theory (DFT) and molecular modeling for his thesis project at the QTEA research group. For his Master's degree, completed at Escola Politécnica (Universidade de São Paulo) in 2009, Dr. Ramos researched the applications of DFT in predicting reaction rates and their uses in designing chemical reactors for Advanced Oxidation Processes (AOPs). In 2014, he received his Doctorate of Engineering (D.Eng.) from the Tokyo Institute of Technology. His doctoral research centered on the application of microfluidics to intensify AOP equipment, at Ookawara Laboratory. Upon returning to Brazil, Dr. Ramos received a FAPESP Post-Doctoral scholarship, allowing him to investigate novel reactors for photocatalysis. During this period, he spent time as a visiting scholar at Università degli Studi di Palermo, working under Prof. Alberto Brucato on the modeling of photocatalytic reactors. Afterwards, he collaborated with the Research Center for Greenhouse Gas Innovation (RCGI), where he was involved in photocatalytic CO2 reduction and reactor development projects. Before his current role as an Assistant Professor at FEI, Dr. Ramos was a part of the research team at the Bionanomanufacturing Center of the São Paulo State Institute of Technological Research. There, he concentrated on the use of microfluidics for Process Intensification. Dr. Ramos values the collaborative aspects of both academic and industrial research and is committed to contributing further to the field of sustainable chemical engineering.Current positions:
