Dr. Ghishan is internationally recognized for his research in pediatric gastroenterology and nutrition. In the course of his career, he has authored more than 400 publications including original articles, editorials, abstracts, book reviews and chapters. He has contributed significantly to the major textbooks in pediatric gastroenterology including: Pediatric Gastrointestinal Disease, Pediatric Nutrition, Nelson’s Textbook of Pediatrics, Liver Diseases in Children and Textbook of Clinical Pediatrics. He is an associate editor for the major textbook, Physiology of the Gastrointestinal Tract. His work has been continually funded by the National Institutes of Health for more than 30 years. In 1996 and again in 2008, he received the prestigious MERIT Award from the National Institutes of Health for “Consistent and Excellent Contributions to Scientific Knowledge”. In 2004, Dr. Ghishan was the recipient of the Shwachman Award presented for major, life-long scientific and educational contributions to the field of pediatric gastroenterology, hepatology or nutrition in North America. In 2014, he was presented with the "Horace W. Davenport Distinguished Lectureship Award" by the Gastrointestinal & Liver Section of the American Physiological Society.

His laboratory is currently funded by five R01 grants from the NIH. Two of the R01’s have been funded for more than 25 consecutive years.  One deals with intestinal ion transport of phosphate across the gastrointestinal tract and the other deals with intestinal ion transport. His research emphasis is in the area of ontogeny of intestinal transport which he has brought to the highest level of research intensity from in vivo to genetic regulation.
