PhD in Sanitation, Environment, and Water Resources (PPGSMARH/UFMG, 2024); Master in Environmental Technologies (PPGTAmb/UTFPR, 2020); Degree in Geography (Claretian, 2019); Environmental Engineer (UTFPR, 2017).Dr. Marchesi has experience as a higher education professor. He worked at the Department of Sanitary and Environmental Engineering (DESA/UFMG, 2023/2024), teaching Water Supply Systems, Sewage Systems, Diagnosis and Assessment of Surface Water Pollution, Introduction to Environmental Sciences, and Environmental Protection. He also served at the Department of Food Engineering (DAALM/UTFPR, 2021), teaching core engineering subjects, including Introduction to Engineering, Unit Operations, and Transport Phenomena.He has published Engineering, Environmental Sciences, and Geography papers. His doctoral research focused on Public Policies and Management in Basic Sanitation, emphasizing the monitoring of geographic inequalities in access to water and sanitation within Brazil's maritime island territories. During his master’s studies, he conducted experimental research on Waste Treatment and Valorization Technologies, focusing on Constructed Wetlands, with physical-chemical sewage analyses experience. As an undergraduate, he worked as a teaching assistant for the Biostatistics course in Environmental Engineering and participated in a scientific initiation project on Recirculating Aquaculture Systems (RAS), involving biological effluent treatment.Currently, he is a postdoctoral researcher at the René Rachou Institute – Fiocruz Minas, where he collaborates with the research group Public Policies in Human Rights in Health and Sanitation (PPDH). His work focuses on developing tools to support the creation of the National Indigenous Sanitation Program (PNSI).
