Mechanical Engineering Student Hamidreza Zobeiri Wins Zaffarano Prize – Graduate College

Hamidreza Zobeiri, Ph.D. Candidate in Mechanical Engineering, is the recipient of the 2022 Zaffarano Award for Graduate Student Research. Each spring semester, the Graduate College gives this honor to a graduate student with superior publishable research.

Dr. Daniel Zaffarano, former dean of Iowa State Graduate College, believed that publishing was an important component of the graduate student experience. In the hundreds of graduation interviews he conducted with graduate students, Zaffarano had a favorite question: “Do you plan to publish your research?” He established this award in 1988, after retiring from Iowa State.

Zobeiri published 14 research papers as a senior author while at Iowa State. He is also co-author of seven articles.


As he writes and edits articles, Zobeiri also searches for suitable journals where he could potentially publish his work. He compiles a list of suitable journals, and after a discussion with his homeroom teacher, they decide where to submit it. He may then be called upon to make revisions according to the requirements of the journal.

Although this process can be challenging, Zobeiri also finds it rewarding.

“It’s very gratifying for me when I see one of my publications being cited by other researchers in another corner of the world and has helped them in their research, or they have used our result as a reference”, a- he declared.

He has also experienced setbacks during his research, but he advises other graduate students not to be disappointed or discouraged during the research process as long as they are working towards their goals.

“Sometimes an article may be rejected during the submission process, or you may not get your expected experience results. But that’s part of the nature of academic research,” he said. “For example, I worked on a project for a few months in my first year that didn’t result in any publications, but it made me very experienced and gave me a lot of ideas that helped in the following projects which led to more publications. »

Zobeiri’s research focuses on thermal characterization at the micro/nano scale. As materials and structures decrease in size and reach the micro/nano level, the way they transport heat differs from larger structures. Zobeiri uses a range of methods to study these small structures. His research has applications in many fields, from solar cells and microelectronics to materials science and thermal and optical metrology.

Zobeiri came to Iowa State for this research after completing his undergraduate studies at the University of Tehran. Iowa State was one of his top choices for his Ph.D.

“Iowa State’s Department of Mechanical Engineering is nationally and globally prestigious, with many incredible faculty. Also, when I was looking at different professors and their areas of research at Iowa State, I found [mechanical engineering professor Xinwei] Wang’s research area was very close to my interests,” he said. “After contacting Professor Wang and discussing his research plans, I decided to join his lab and Iowa State.”

Wang is Zobeiri’s homeroom teacher and nominated him for this year’s Zaffarano Prize. In his nomination letter, Wang wrote that Zobeiri’s work is pioneering, groundbreaking and expected to have a long and profound impact on micro/nano scale thermal science.

“[Winning the Zaffarano Prize] means a lot to me! Most importantly, I am honored to receive this award, and it means that my research achievements have been recognized by the academic/scientific community at UIS, as it is only awarded to a few researchers per year,” said said Zobeiri. “It also motivates me to work harder and more passionately in my professional life.”

After graduating this fall, Zobeiri hopes to begin a position as a research scientist or postdoctoral researcher at a national laboratory, where he can apply his research experience while continuing to expand his knowledge.
