Biography Summary

Ali Lohi is an Adjunct Professor in the Chemical Engineering Department at the University of Waterloo.

His research focuses on simulation/modeling and optimization of chemical processes through application of experimental research and computational techniques (CFD, DEM and ANN). Professor Lohi has been actively involved in development of processes and simulated models for reduction in energy consumption, remediation of membrane fouling, development of innovative and proficient green energy processes, utilization of waste materials into new and value-added products including biofuel/bioenergy and syngas from agriculture waste, and enhancement of the downstream processes of the oil/gas industry. Professor Lohi has made significant contributions to the fundamental understanding of chemical and industrial processes through scale-up and simulation-based research.
