Yueyi (Diana) Sun (PhD student)

Email: ysun340@gatech.edu

She joined Dr. Alexeev’s lab in 2014 as an undergraduate student though the undergraduate research program. She received BS degree in Mechanical Engineering from Georgia Tech in 2016 and decided to continue as a graduate student in Dr. Alexander Alexeev’s lab. Her research focuses on the interdisciplinary area of complex fluids flow and biophysical mechanisms. She examines the complex blood clotting process – interactions between fibrin, platelet, red blood cell and blood flow inside blood vessel using mesoscale modeling techniques. Her research interests are: Computational fluid dynamics, multiscale modeling, coarse-grained methods;¬†Microfluidics and biomimetic systems; Coupling between hydrodynamics and soft materials.

She has a passion to serve the community. She joined executive board of MEGA (Mechanical Engineering Graduate Association) in 2017 and is currently serving as the president of MEGA. She is working on improving the department environment of George W. Woodruff School of Mechanical Engineering – making it more active and more inclusive, not only among students but also between faculties and students. She is student representative and member of George W. Woodruff School of Mechanical Engineering Diversity, Equity, and Inclusion Council (DEI) since 2020-present. She is student representative and member of Woodruff School Graduate Student Development Committee (GSDC) since 2021-present.

She has a passion to teach. She has experiences of being Teaching Assistant for multiple classes (Calculus 1; Differential Equation, Fluid Mechanics). Spring 2022, she is teaching ME-3340 Fluid Mechanics (in-person section) as Student Instructor. Summer 2022, she will teach ME-3340 Fluid Mechanics ( in-person and virtual sections) as Student Instructor.

New research shows platelets do their job better when not in total sync with one another

From left, researchers Wilbur Lam, Alexander Alexeev, and Yueyi Sun hope their findings open medical options for people with clotting issues.
