Dr. Marcellus de Moraes is an Assistant Professor at the State University of Rio de Janeiro (UERJ) and a postdoctoral researcher at UFRJ (PEQ/COPPE) He holds a cum laude B.Sc. in Chemical Engineering (2016) from the Federal University of Rio de Janeiro (UFRJ), as well as an M.Sc. (2017) and a Ph.D. (2023) in Chemical Engineering from UFRJ. During his doctoral studies, Dr. de Moraes was awarded a Fulbright Doctoral Dissertation Research Award and conducted a research stay at the Massachusetts Institute of Technology (MIT, Myerson Lab). He also completed a research internship at the Georgia Institute of Technology (Grover Lab). His research is focused on process systems engineering, particularly on the modeling and control of chemical processes. His specific interests include mathematical modeling, optimization, machine learning, real-time monitoring, and the control of crystal size, shape, and polymorphism in crystallization systems—especially for active pharmaceutical ingredients (APIs).
