Current Position

Dr. Mehrvar is the Associate Chair for Graduate Studies in the Department of Chemical Engineering at Toronto Metropolitan University. His main goal is to promote the quality of education across all levels of graduate programs. He began his administrative work at Toronto Metropolitan University in 2009 as the Chair of the Department of Chemical Engineering.

Besides his current position, Dr. Mehrvar is also passionate about teaching. He has been teaching both undergraduate and graduate level courses at Ryerson since 1998. He believes that knowing the materials and transferring the knowledge are complementary. To him, teaching is a skill that requires both mastery of the subject matter and of transferring techniques. His teaching philosophy is driven by how students are able to best learn by thinking, practicing, and completing real life problems.

Dr. Mehrvar's strong commitment to research has also led him to successfully obtain more than $2 million in funds and grants from various funding agencies such as NSERC Grants, Canadian Queen Elizabeth II Diamond Jubilee Scholarships (QES), Industrial Grants, and Toronto Metropolitan University Grants. Moreover, he has supervised/co-supervised more than 45 graduate  students in both master’s and doctoral levels, more than 80 research assistants, and visiting scholars, and multiple undergraduate fourth year’s thesis’. Finally, he has authored/co-authored over 118 refereed journal papers, 6 book chapters, 24 conference proceedings, and more than 176 presentations/abstracts. He has also conducted over 25 international invited seminars and workshops.

To Students

Dr. Mehrvar enjoys teamwork and interacting with different groups of researchers, especially with training graduate and undergraduate students. Below are some advice from Dr. Mehrvar to the students:

  • Participate in conferences and present your work, no matter how small or big their results are. You will get constructive feedback and learn about your discipline.
  • Participate in seminars.
  • Take extracurricular activities. They are so important and beneficial. 
  • Have regular meetings with your supervisors, both in groups and/or individually.
  • Offer to present your research progress regularly to your supervisors.

"I encourage all my graduate students to learn more than their own project for their thesis; in other words, they should learn the area they are doing research. I always advise them to continuously keep up to date with literature."

Dr. Mehrvar, 2020
