About: 

Dr. Pappou completed his General Surgery residency training at the Johns Hopkins Hospital in 2014, with a Research Fellowship in Surgical Oncology at the Sidney Kimmel Comprehensive Cancer Center (Johns Hopkins). He has completed a Clinical Fellowship in Colon and Rectal Surgery at NewYork-Presbyterian/Weill Cornell and the Memorial Sloan Kettering Cancer Center in 2015.

His clinical interests include the entire spectrum of colorectal surgery including benign and malignant conditions, anorectal, abdominal and pelvic surgery as well as minimally invasive techniques including laparoscopic, robotic and endoluminal procedures. Dr. Pappou is well versed in utilizing minimally invasive approaches including robotic surgery and sacral neurostimulation (SNS). Dr. Pappou is the surgical lead of the pelvic floor center within the division of colorectal surgery, working with gastroenterologists, urologists and gynecologists to develop a one-stop program for evaluation and treatment of problems related to colon transit, constipation, pelvic floor and evacuatory dysfunction as well as fecal incontinence.

His position also includes leadership in clinical and laboratory research and outcomes within the division of colorectal surgery. He has a keen interest in research and is an author on numerous publications in peer-reviewed journals, published abstracts, oral presentations and book chapters.

Dr. Pappou has been the recipient of numerous prestigious awards, including the Johns Hopkins George D. Zuidema Research Award for Meritorious Laboratory Research for work on novel chemotherapy treatments in colorectal cancer.

A native of Greece, Dr. Pappou graduated from the Medical School of the Technical University of Munich with honors in 2006 and completed a Ph.D. on human stem cells at the research laboratory of the Ludwig Maximilian University of Munich, Germany.
