He received his medical degree from Sapporo Medical University School of Medicine and his PhD. from Iwate Medical University in Japan. He completed his residency training at Memorial Heart Center, Iwate Medical University, where he also served as assistant professor of cardiovascular surgery.

Nicole R. Sydow, MD, joined the UA Department of Surgery as clinical instructor in the Division of Cardiothoracic Surgery. She joined the department after completing an advanced cardiothoracic surgery fellowship at the UA. She completed general surgery residency training at the Cleveland Clinic and earned her medical degree from Southern Illinois University School of Medicine.
