Dr. Hassan S. Ghaziaskar is now a visiting researcher at the mechanical engineering department, at Carleton University, and professor emeritus of the Department of Chemistry, at the Isfahan University of Technology since Sept. 2023. He received his BSc in chemistry from the University of Isfahan (1986), MSc from Mazandaran University, Iran (1988), and Ph.D. from Carleton University, Canada (1993) focusing on developing a laser-based sensor for monitoring chemicals in production lines. After his Ph.D., he was employed in the Department of Chemistry, at the Isfahan University of Technology to teach analytical and applied chemistry. His research mainly focuses on novel methods of extraction and reaction under supercritical fluids. Moreover, he was able to establish a Startup to transfer some of the ideas from the laboratory to pilot and then industrial scale. He is currently producing more than 10 products including animal feed as well as a buffer for dairy cattle in Iran and Cat litter for the 1st time in Iran. Production of ethylene glycol monoacetate and ethylene glycol diacetate as fuel additives at the lab and pilot scale in a continuous system using waste ethylene glycol, synthesis of acetins from bioglycerol at the lab and pilot scale as a green fuel additive, and synthesis of solketalacetin at the lab scale as a green fuel additive. He has been in Japan as a researcher (Sept. 1997 to June 1998), at Tohoku National Industrial Research Institute, Sendai, and on sabbatical leave in Canada, (Nov. 2010 to Aug. 2011), at the chemical engineering department, Lakehead University, Thunder Bay, and institute for chemicals and fuels from alternative resources, faculty of engineering, University of Western Ontario, London, ON. He has also had more than 25 years of management experience at universities and in economic positions. He has published more than 84 scientific papers in prestigious journals and graduated more than 20 graduate students.
