Personal History:

Dr. Alaish came to Baltimore in 2002 from New York, where for the previous three years he was on faculty at the College of Physicians and Surgeons of Columbia University. Concurrently, he was the Chief of Pediatric Surgery at Saint Vincent's Hospital in Manhattan.

After graduating with honors from Duke University with a degree in biomedical engineering, Dr. Alaish received his medical degree from the University of Maryland School of Medicine in 1990. He completed his General Surgery residency at the Medical College of Virginia in Richmond in 1997. During his residency, he spent two years studying fetal wound healing, for which he garnered both local and national research awards. He continued his training by completing a Pediatric Surgical fellowship at the Babies and Children's Hospital of New York at Columbia-Presbyterian Medical Center in 1999.

Dr. Alaish is board-certified in both General and Pediatric Surgery. He is a Fellow of the American College of Surgeons and the American Academy of Pediatrics. He is also a member of the American Pediatric Surgical Association and resided on its national education committee. He has been selected by the Consumers' Research Council of America as one of "America's Top Surgeons" in both 2008 and 2009.

Research Interests:

His basic science research interests focus on the genetics behind the innate immune response following cholestasis.

Clinical Speciality:

Dr. Alaish performs many varied types of surgery, including surgery for newborn anomalies, esophageal, gastrointestinal and biliary reconstruction and minimally invasive surgery (thoracoscopy and laparoscopy) on infants and children of all ages. He also performs chest wall reconstruction, including the Nuss procedure, for pectus deformities.
