Stefania Impellizzeri

Dr. Stefania Impellizzeri received a Laurea in Chemistry, cum laude, from the Department of Chemistry “Giacomo Ciamician” at the University of Bologna, and a Ph.D. in Chemistry from the University of Miami. She later joined the University of Ottawa as a postdoctoral fellow and one of the winners of the Banting PDF competition, before joining  Ryerson University in 2018 as Assistant Professor in the Department of Chemistry and Biology. Her expertise extends from organic synthesis to photo- and physical chemistry, materials chemistry, catalysis, and supramolecular chemistry. Her research focuses on the design and synthesis of organic and bioinorganic probes for bioimaging, biosensing and molecular computing, sustainable 'smart' materials and devices, metal nanocatalysts, and nanoengineered textiles and coatings. She was awarded the 2021 PCCP Emerging Investigator Lectureship Award from the Royal Society of Chemistry, which recognizes emerging scientists who are making outstanding contributions to physical chemistry, chemical physics or biophysical chemistry.

Hadis Zarrin

Dr. Hadis Zarrin is an Assistant Professor of Chemical Engineering at Ryerson University, the Director of Nano-Engineering laboratory for Energy and Environmental Technologies (NLEET), and the Vice-Chair of Energy Division at Chemical Institute of Canada (CIC). She holds a PhD in Chemical Engineering from University of Waterloo with 11-year experience of nanostructured materials development for electrochemical energy storage and sensing devices. Currently her research is focused on the design and engineering of smart multifunctional nanostructures and nanocomposites for clean energy storage and conversion, wearable biosensor systems, smart coatings, and environmental remediation. Her achievements have resulted in five awards, one patent, three book chapters, and >20 peer-reviewed published papers in prestigious journals with >1261 citations to date. Notably, she was the first researcher that engineered the chemical structure of graphene oxide (GO) to overcome the durability challenges of electrolytes in electrochemical systems like fuel cells and alcohol sensors. Published in The Journal of Physical Chemistry C with >383 citations to date, this work globally inspired other researchers and companies to collaborate with NLEET and use the graphene-analogous nanostructures and multifunctional nanaomaterials as booster components in different applications including energy-storage devices, gas and chemical sensors, smart coatings, and smart healthcare wearables.
