Dr. Cao won the prestigious NSF CAREER award! We will use atomistic simulations, first-principles calculations, and phase-field finite element modeling to investigate the thermomechanical processing in titanium alloys. The work will potentially advance the manufacturing of stronger and more ductile titanium alloys.

Dr. Cao is the lead PI and will work closely with Dr. Yan Wang (co-PI) from UNR and Dr. Jaeyun Moon (co-PI) from UNLV on this exciting project.
More detailsDr. Cao and Amir took a picture in front of Palmer Engineering. Amir has been awarded the the prestigious Dean’s Merit Scholarship as well as the Outstanding Graduate Student Scholarship for his excellent research and academic achievements. Amir will join the University of Michigan as a postdoc associate to continue his work on metals and alloys.
Congratulations, Amir!
"One common thing I get asked is how I feel about choosing the field of engineering as a woman or if I feel a sort of responsibility, and I do feel a responsibility," Cao said. "I think it's very important to have more women engineers in the STEM field because we don't realize how important it is to have role models for students."
More detailsCao’s project involves developing computer models that can predict how microstructures within titanium alloys change under heat and pressure. The computer models can connect atomic-level material processes to design macroscopic material properties by rationally designing microstructures. The project also will advance another of her goals: preparing students in Science, Technology, Engineering and Math (STEM) for the workforce by with integrated skills in mechanical engineering and materials science.
