Sydney Smith

IMMUNOLOGY PROGRAM GRADUATE STUDENT CANDIDATE

Biography

Sydney is entering her third year in Immunology PhD program at UM working in the lab of Charles Parkos. In 2017 Sydney graduated magna cum laude from University of San Diego, receiving a Bachelor of Arts degree in Biology and a minor in Chemistry. Currently, Sydney serves as a representative for both the Biomedical Graduate Student Government and Office of Graduate and Postdoctoral Studies Health and Wellness Committee. Collaborating with these organizations, she is working to find solutions to address food insecurity and wellness issues within the graduate student community. During her first two years at Michigan, Sydney served on the Executive Board for the Association of Women in Science (AWIS). During her time with AWIS Sydney helped launch an after school science mentoring program at Forsythe Middle School, which is now successfully entering its third year.
 

Research Interests

In response to mucosal injury or infection, neutrophils infiltrate the intestinal mucosa and traverse the epithelium through a coordinated process termed transepithelial migration. Excessive neutrophil transepithelial migration is correlated with Inflammatory Bowel Disease. Neutrophils transmigration requires coordinated interactions between neutrophil adhesion receptors and epithelial intercellular junctions. Current evidence suggests that epithelial tight junction proteins, including members of the Junctional Adhesion Molecule (JAM) family serve as receptors to migrating neutrophils. Sydney is working to delineate and understand the role of signaling events downstream of JAM family tight junction proteins that occur in response to neutrophil transmigration and intestinal inflammation.
