Academic Distinctives

Dr. Johnson has worked with several students, and in 2021, she worked with a student who was a Noyce scholar, to grow a mouse macrophage cell line (J774), treated the cells with Toll-like Receptor (TLR) ligands, and assess cytokine production via ELISA.

Dr. Johnson is affiliated with the Center for Bioethics and Human Dignity and the American Association of Immunologists.
