Marcellus de Moraes is a doctoral candidate in the Chemical Engineering Program at COPPE/UFRJ. He earned his BS in Chemical Engineering (cum laude) from the Universidade Federal do Rio de Janeiro and his MS in Chemical and Biochemical Process Engineering from the same university. He was a lecturer in the Department of Chemical Engineering at the School of Chemistry at UFRJ (2017-2018). In his doctorate, he did a sandwich period at the Georgia Institute of Technology (Georgia Tech), USA, under the CAPES/PrInt program. In his studies, he researches mathematical modeling, monitoring and controlling the size and shape of particles in crystallization processes. An important application of his research is for the crystallization of drugs, more specifically praziquantel, a medicine used in the treatment of schistosomiasis – one of the most neglected tropical diseases in the world, strongly related to poverty.
