Research Scientists

Krissy Kigerl portrait 2021.JPG

Kristina (Krissy) Kigerl, PhD

Krissy received a PhD in 2006 from the Ohio State University in the Popovich lab, with funding from an NIH F31 fellowship. During her PhD, Krissy characterized the role of the innate immune response and toll-like receptors in experimental spinal cord injury. In 2007 she became a Craig H. Neilsen post-doctoral fellow in the Popovich lab, where she identified macrophages with distinct phenotypes in spinal lesions. Since 2011, Dr. Kigerl has been a research scientist in the Popovich lab investigating how gut dysbiosis impairs recovery from spinal cord injury. In her free time Krissy enjoys spending time with her family, reading, and being outdoors.

Jodie.jpg

Jodie Hall, PhD

Jodie completed her PhD at Queen Mary University of London in England in 2010. She coordinates research at the Belford Center for Spinal Cord Injury. In collaboration with other Belford Center researchers, Jodie studies ways to prevent complications such as pneumonia and changes in gut bacteria after spinal cord injury. Jodie is also funded by the Ohio Third Frontier and Wings for Life Foundations to investigate ways to “train" immune cells to help fight infections after spinal cord injury. Jodie enjoys spending time with her young family and hopes to revive former hobbies of Capoeira, travel, and hiking.

Brennan, Faith_photo_edited.jpg

Faith Brennan, PhD

Faith completed her PhD in Physiology at the University of Queensland in Australia in 2015. She first joined the Popovich lab as a post-doctoral fellow in August 2016 and became a Research scientist in the summer of 2020. Her research, funded by fellowships from the Craig H. Neilsen and Wings for Life Foundations, explores how resident cells in the spinal cord called microglia can be harnessed to improve outcomes from traumatic spinal cord injury. Faith also received funding from the Neuroscience Research Institute and the Chronic Brain Injury Discovery Themes Initiative. Outside the lab, Faith enjoys drawing, graphic design, running, and eating cake.
