Research Summary

Dr. Johlin's research interests relate to the hepatic folate metabolic pathway. Additional interests include the effects of antifolate therapies on one-carbon metabolism including the fate of methanol, formate, and formaldehyde. His clinical research interest is in the development of techniques and devices to be used in therapeutic endoscopy and ERCP. His key interests are folate metabolism, formyltetrahydrofolate dehydrogenase, and therapeutic biliary tract endoscopy and lithotripsy.
