DR. PEDRO ORTIZ

Research Associate

Pedro Ortiz.jpeg

Pedro Ortiz was born in Havana, Cuba. He received a BSc in Chemistry (summa cum laude) at the University of Havana, under the supervision of Dr. Alex Fragoso. He obtained his PhD in Chemistry, with Cuban Science Academy’s Award, at the University of Havana, under the supervision of Dr. Pedro Ortiz del Toro, and Dr. Gunther Hennrich (from the Autonomous University of Madrid). He joined the Department of Inorganic Chemistry at the University of Havana as an Assistant Professor. Later, he joined Dr. Eduardo Schott’s Group at the Catholic University of Chile as a PDF and one of the winners of the Fondecyt/ANID grant. He also collaborated as an associate researcher on several projects devoted to nanostructured materials for catalysis and photocatalysis applications. At TMU, he joined the group of Dr. Bryan Koivisto, and recently that of Dr. Stefania Impellizzeri. 
His scientific interests are related to the design, preparation, and characterization of organic and inorganic materials, and composites for a broad scope of applications.

DR. RYAN HUTCHINS

Research Associate

Ryan Hutchins earned a BSc and MSc from the University of Waterloo and a PhD from the Université du Québec à Montréal. Following the PhD, Ryan completed post-doctoral fellowships at the University of Alberta and the University of Waterloo. Ryan's research has focused on understanding the water chemistry and biogeochemistry from diverse impacted and unimpacted environments using a wide variety of analytical instruments and methods. Dr. Hutchins’ current research projects at Toronto Metropolitan University focus on the analytical aspects of ice-making and water quality (part of the Jet Ice Chair in Sustainable Materials Chemistry initiative) and in collaboration with Urban Water TMU.

EMMANUEL FAGBOHUN

PhD Candidate

Emmanuel earned his Bachelor of Science in Chemistry from the University of Ilorin, Nigeria, and a Master of Science in Engineering (Applied Chemistry) from the University of the Chinese Academy of Science (UCAS), Beijing, China. He did two years of research in materials science at the Institute of Process Engineering, Chinese Academy of Science. He was awarded the Chinese Government Scholarship and the University of Chinese Academy Scholarship for his master's program. His previous research focused on synthesizing nanomaterials and their applications in energy and hydrogen storage, and wastewater treatment. His research is focused on the synthesis of carbon-based materials for water splitting and hydrogen production.
