A Professor of Medicine, Dr. McGrath's research focuses on endotherapy for the management of Barrett's esophagus and superficial esophageal cancer, evaluation of pancreatic cystic lesions and cyst aspirate analysis, and EUS-guided tissue acquisition.
Therapeutic endoscopy, endoscopic ultrasound (EUS) for the diagnosis and staging of GI malignancies, pancreatic cystic neoplasms, management of dysplastic Barrett’s esophagus and superficial adenocarcinoma via endoscopic therapy (radiofrequency ablation, cryotherapy and endoscopic mucosal resection), esophageal stricture management, eosinophilic esophagitis and GERD.
