Dr. Marzieh Heidari Nia is a chemist with a multidisciplinary focus, working at the intersection of sustainable materials, physical chemistry, organic chemistry, and nanotechnology. She earned her first Ph.D. in Chemistry from Shahid Chamran University of Ahvaz, Iran, through a collaborative program with McGill University in Canada. Currently, she is pursuing a second Ph.D. in Physical Chemistry at the University of Saskatchewan. Her research explores the design of soft functional materials—particularly hydrogels, biopolymer-based coacervate complexes and nanoscale carriers—used in drug delivery systems and antibacterial surface coating applications. She is especially interested in the use of radiolabeling techniques for cancer therapy and in developing smart, stimuli-responsive materials. Beyond soft matter, Dr. Heidari Nia investigates hybrid silica nanoparticles and other nanostructures, focusing on how their composition and surface properties can be tuned for enhanced performance in biological or environmental settings. Her broader goal is to advance the design of materials that align technical performance with environmental responsibility, biocompatibility, and real-world usability. She is also engaged in collaborative, interdisciplinary research and committed to applying chemistry to address global health and sustainability challenges.
