Stephanie received her BS degree in Mechanical Engineering and was minoring in Mathematics and Biological Sciences. She was the President of the Illinois Epsilon chapter of Tau Beta Pi, the Vice President of the American Society of Mechanical Engineers, the Treasurer of Engineering Student Council, and was very involved in her sorority, Alpha Gamma Delta. In 2013, she was a recipient of the Chancellor’s Scholarship at SIU. She began working in Dr. Chu’s lab as a freshman through the Research Rookies program doing research in Biomedical Engineering. She was later supported by the undergraduate research assistantship to conduct research in the field of Nondestructive Evaluation and biomedical engineering. She received the college of Engineering Outstanding Senior award early this year. She is now a graduate student with full scholarship to study biomedical engineering at Purdue University.


Runyu Zhang
Degree: B.S. in Mechanical Engineering 5/2017
LinkedIn: Runyu Zhang

My name is Runyu Peter Zhang. I started working in IMEL for Dr. Chu from 2015 to 2017, as an undergraduate research assistant. This experience has been tremendous for me, during which time I start to learn how to conduct research. Also other members from IMEL taught me a lot, especially Dr. Chu. With their help, I was honored to be awarded 2016 ASNT Engineering Undergraduate Scholarship. Right now I am a Ph.D. student at University of California, Riverside. It is with IMEL, Dr. Chu and my knowledgeable labmates’ help, I am able to do the research that I am devoted to. Great thanks to them!

Ryan Spencer
Degree: M.S. in Mechanical Engineering 5/2017
LinkedIn: Ryan Spencer

Ryan Spencer received his Master’s degree at SIU studying Mechanical Engineering this year. In 2013, Dr. Chu hired Ryan as an Undergraduate Research Assistant at IMEL. Since then, Ryan has conducted research and worked on projects in Nondesctructive Evaluation. These projects include evaluating adhesive bonds and composite components for aerospace applications using multiple methods such as ultrasonics, infrared thermography, and digital image correlation. Ryan’s research focuses on using an ultrasonic technique to evaluate porosity within carbon composite components.

Outside of his research with IMEL, Ryan was active with the SIU Moonbuggy design team, a student organization that competes in the annual NASA Rover Challenge. In 2013, Ryan was the President of the SIU Moonbuggy Design Team. As President, Ryan worked directly with Dr. Chu, the team's faculty advisor, and led the team to a successful 2nd and 3rd place finish. Ryan also serveed as the President of the SIU NDE student organization, which aims to increase interest and understanding of NDE in the community. Ryan is currently pursuing a Ph.D. degree at University of Tennessee in Knoxville and conducting research at Oakridge National Laboratory.
