Dr. Hyun Jung Kim, an Assistant Professor at Case Western University specializes in coaxing human cultured cells to differentiate and form tissues resembling the gastrointestinal tract, in order to study microbe-GI interactions.  Dr. Kim discusses his surprising discovery of how common immortalized cultured cells can differentiate and form something that resembles a gut-on-a-chip, how these guts-on-a-chip can be used to study diseases like inflammatory bowel disease and colorectal cancer, how the addition of a microbiome to the gut-on-a-chip allows the bacteria to retain diversity unlike in a test tube, how the gut-on-a-chip could be valuable for personalized medicine, and the things he misses about Texas since moving from there.
