Congratulations, Madison and Sydney, for graduating from OSU’s College of Medicine!

Congratulations to Sydney Castellanos and Madison Hart who are both OSU COM M4 students.

Sydney matched into General Surgery at the University of Pennsylvania and Madison matched into combined

Medicine/Pediatrics residency program at the University of Minnesota!

So proud of these two STARs!

Jaden Levinson

Started OSU undergrad in 2024, Joined the Bumgardner Lab in February 2025.I am an honors Biochemistry student on the pre-med track at Ohio state’s college of arts and sciences. I understand the importance that immunology plays in medicine, and as well as being fascinating to learn, Immunobiology is applicable in almost every specialty. What interested me about the Bumgardner Lab combines a highly collaborative, team-oriented research experience with the common goal of alleviating patients for the need of taking immunosuppressants. Every day I am thrilled to learn more about Transplant Immunobiology and make my own contributions to science and medicine

Bumgardner Lab member Colleen Booth presented her research, Investigating the Memory Capacity of CXCR5+CD8+ T Cells at the Autumn Undergraduate Research Festival hosted by the Undergraduate Research & Creative Inquiry Department, OSU.

Hatem Aldhahi, Undergraduate Student Researcher

Hatem is a first-year Biochemistry major at the Ohio State College of Arts and Sciences. He joined the Bumgardner Laboratory in August 2023. Hatem hopes to learn more about how immunology plays a role before, during, and after a surgery, and he is excited to contribute to the ongoing research in the lab.
