Biographical Statement

Isaac completed his bachelor’s degree in Chemical Engineering at the University of Puerto Rico, Mayagüez in 2020. He conducted research in synthesis and detection of highly energetic materials for counterterrorism with Dr. Samuel Hernández-Rivera and synthesis of composite metal organic framework for wastewater treatment with Dr. Arturo Hernández-Maldonado. He was also a mentor at the Center for Pharmaceutical Engineering. Currently he is investigating the effect of polymer chemistry on the physical properties of solid polyelectrolyte complex films and is a mentor of the STEM Ambassadors Program.
