Rohit Kohli, MBBS, MS Director, Liver Transplant Program 513-803-7044 firstname.lastname@example.org
Director, Liver Transplant Program
Attending Physician, Liver Care Center
Non-alcoholic steatohepatitis; liver transplantation; mitochondrial hepatopathies
Rohit Kohli, MBBS, MS, is currently an associate professor of pediatrics at the University of Cincinnati College of Medicine and the co-director of the Cincinnati Children's Steatohepatitis Center.
Dr. Kohli received his medical degree from the Armed Forces Medical College, India in 1999 and his MS in clinical investigation from Northwestern University in 2006. While at Northwestern he first spent three years as a pediatric gastroenterology and hepatology fellow and then subsequently as a transplant hepatology trainee before relocating to the University of Cincinnati in 2007.
His research work has focused on the pathogenesis of obesity related fatty liver disease (NAFLD). In particular, he has focused upon the role of reactive oxygen stress in the generation and regulation of the extreme stage of this disease; nonalcoholic steatohepatitis (NASH). Dr. Kohli's laboratory currently focuses on the role of fructose in triggering above mentioned oxidative injury and fibrosis within the liver. He also works with Drs. Randy Seeley and Stephen Woods at the Metabolic Diseases Institute at the University of Cincinnati to understand the mechanism and impact of bariatric surgical procedures on NASH and other co-morbidities of obesity.
He has published many peer-reviewed articles including articles in The Journal of Biological Chemistry, Hepatology, Journal of Pediatrics, and The American Journal of Physiology. He is the author of many book chapters and review articles. He also is the recipient of the 2007 George Ferry Young Investigator Award from the Children's Digestive Health and Nutrition Foundation and a Fellowship award from the American Association for the Study of Liver Diseases. His clinical efforts are focused within the Steatohepatitis Center and Liver Care Center in the Division of Gastroenterology, Hepatology and Nutrition at Cincinnati Children's Hospital Medical Center.

Associate Director, Pediatric Surgery Fellowship
As a pediatric surgeon and a transplant surgeon, Dr. Tiao is involved in the care of children afflicted with biliary atresia from the time of presentation and diagnosis to the initial Kasai portoenterostomy to the liver transplant, when necessary. He sees the many challenges children and their families experience when diagnosed with this life threatening disease process. From that perspective, defining the basis of this disease process such that therapeutic strategies can be developed eliminating these complex interventions is his career goal. His short term goal is to develop an independent research laboratory investigating the pathogenesis of virus induced biliary atresia specifically seeking to determine the mechanistic basis of this disease so that new treatment strategies can be developed to salvage the native liver.
Dr. Tiao's overarching hypothesis is that biliary atresia results from the infection of cholangiocytes by a virus triggering immune-mediated biliary obstruction. His focus is to determine the mechanisms used by RRV to infect cholangiocytes, how RRV undergoes replication within the cholangiocyte, and how infected cholangiocytes modify the microenvironment, activating the immune system resulting in biliary obstruction. Determination of the mechanistic basis of these inter-related events is essential to understanding the pathogenesis of virus induced BA. By focusing on the basis for the viral insult in the initiation of biliary atresia, he has defined an area of independence from Dr. Jorge Bezerra, his primary research mentor.

Vascular access; gastrointestinal interventional radiology
John Racadio, MD, has been practicing interventional radiology (IR) for 14 years and has been the division chief of interventional radiology at Cincinnati Children’s Hospital Medical Center for the past 11 years. He has expertise in performing a wide range of vascular procedures including angiography, angioplasty, embolization, vascular access, and thrombolysis in patients ranging from 500g to 150kg.
He is also the director of the interventional radiology research lab, which is part of the Department of Radiology Imaging Research Center (IRC). This state-of-the-art IR lab, which is identical to our clinical IR labs, possesses cutting edge digital flat detector technology including 3-D rotational angiography (3DRA), 3-D Roadmapping, and C-arm cone beam CT. These features provide superior image quality for digital subtraction angiography, 3-D angiography reconstruction, and “CT-like” imaging. Lab support staff includes RT(R) licensed IR technologists, and an IR lab manager. The long term goal of the IR research lab is to develop new image guided interventional procedures and imaging techniques and protocols to improve clinical outcomes. Having an IR research lab identical to our IR clinical labs facilitates translation of lab results into clinical practice.
