Dr. Kim has training in Medicine and in Research.  Before coming to Saint John’s University, her research was in intravital imaging of immune cells in the central nervous system (CNS) using two photon microscopy.  At Saint John’s University, she is a dedicated teacher of Biology and engages in academic and career-advising to pre-healthcare career track undergraduate students.  Her current interest is in experimenting enhanced pedagogy and applying new educational technology platforms to promote diversity, equity and inclusion.

For Imaging, my main contribution has been examining the immune system dynamics in the central nervous system using intravital multiphoton intravital imaging of mouse models of disease.  Previous works include participation in collaborative landmark finding that ramified microglia are highly dynamic cells at baseline and in response to injury as visualized using CX3CR1gfp/+ mice  (Davalos, et al., 2005; Kim & Dustin, 2006).

Intravital imaging I performed lead to a remarkable finding that extravasation of neutrophils and monocytes into CNS, induce a fatal viral meningitis in the mouse (Kim, Kang et al., 2009).  I also examined the quality and functional consequences of immunological synapse interactions during viral meningitis (Kang et al., 2011).

For Intravital Imaging, I contributed to developing an intact intravital window surgery to image the mouse spinal cord and its covering tissue through intervertebral window between lumbar spines (Kim et al., 2010):

During various Transplant Immunology collaborations, immune cell behavior patterns in transplanted kidney and liver injury were examined by intravital imaging:
