Dr. Marcel Pinheiro's focus is zoology of the invertebrates, primarily benthic invertebrates and those that carry out a parasitic lifestyle. His undergraduate teaching focuses on exposing students to the diversity of eukaryotes, both single- and multi-celled, and striving to provide students with the chance to encounter these organisms in the field. Further, Dr. Pinheiro utilizes various technologies to enhance student engagement and writing in his classroom – at all years of study.

Dr. Pinheiro is currently not active in research, but serves on graduate student advisory committees, and regularly provides peer review for several journals. Dr. Pinheiro's past research centred on the ciliate Tetrahymena thermophila, used as a tool for toxicology, in interactions with bacterial and animal viruses, and how these organisms may function as parasites of fish.
