Graduate Students
Kevin Corn
(kevin.c.corn [at] vanderbilt.edu)
Kevin received his B.S. in Chemical Engineering from the University of Texas at Austin in 2009. For the past 8 years, he has worked at INEOS Olefins & Polymers USA in the Houston, TX area as a technical service engineer, polypropylene product development engineer, and Six Sigma Black Belt. He hopes to combine his industry experience with his past academic research stemming from an REU studying mesenchymal stem cell migration at MIT to solve complex problems in the biomedical field. At Vanderbilt, his research focuses on understanding normal-tissue wound healing due to radiation therapy. He is exploring how this treatment affects cellular metabolism and extracellular vesicle release to impact cell-to-cell communication, and how it potentially influences tumor-cell infiltration and local recurrence for triple-negative breast cancer. Outside of the lab, Kevin is an avid cook and equally avid foodie. He has a (questionably) healthy obsession with K-pop, enjoys laughing along to the comedy/true-crime podcast My Favorite Murder, and spends a significant amount of time talking about his dog Mochi.
Tian Zhu

In the past, her research has involved nanoparticles and nanostructures for biological applications. At Vanderbilt, she is an NSF Graduate Research Fellow and studies the effect of radiation-induced immune cell infiltration on tumor cell recruitment in breast cancer. McKenzie has more hobbies than she does time. She enjoys animals, art/ animation, cross stitching, lore and science podcasts, Dungeons and Dragons, and spending time with her husband, little girl, and guinea pig.
Zachary Vaneman
In 2024, Zach graduated with a B.S. in Chemical Engineering with Honors from Pennsylvania State University. While there, he conducted research on the effects of extracellular matrix properties on cell migration. Zach also spent a summer working in a molecular biology laboratory identifying novel inexpensive means of producing protein standards for size exclusion chromatography. At Vanderbilt, he is investigating the effect of mammary fat pad radiation damage on breast cancer cell migration with a focus on the extracellular matrix. In his free time, Zach enjoys going to the gym, watching sports, spending time outside, and exploring food in Nashville.
Sofia Luna
Sofia received her B.S. In Chemical Engineering from the University of Alabama in 2024. Her research at UA involved hydrogels that mimic the brain tumor microenvironment to study the effects of matrix stiffness on drug resistance in brain metastatic breast cancer spheroids.
