Faculty and Staff

Takuya Saito, M.D., Ph.D

I graduated from Nippon Medical School in 1987, and in 1992 I joined Cornell Medical School, Westchester division as a visiting fellow. In 1993, I embarked on a residency training program in psychiatry at Montefiore Medical Center/Albert Einstein College of Medicine, which I completed in 1997. I was then appointed Chief Resident and was charged with supervising the psychiatry residents. Subsequently, I became a research fellow, during which time I conducted clinical research and provided patient care at the Bronx Psychiatric Center.

My clinical research involved the evaluation of atypical antipsychotic medications in patients with schizophrenia. This work was conducted as part of a wide-ranging multi-site psychopharmacology study. After completing my fellowship, I became a faculty member in the department. As a fellow, I pursued training in molecular genetics techniques and statistics. A number of important papers came out of our Program of Behavioral Genetics Program, including work on a genetic factor relating to violence in schizophrenia and ultra rapid cycling bipolar disorder. Over the years, I received research grants from the American Psychiatric Association and NARSAD that allowed me to work for the Basic Research Division in the Department of Psychiatry, where I focused particularly on identifying a genetic locus on chromosome 22q11 in multiple psychiatric disorders and neurodevelopmental disorders. I also played a major role in providing psychiatric care for the Japanese community in New York by serving as a psychiatric consultant to the Japanese Consul General in New York. I also served as a consultant to the Japan Education Center to help Japanese children with mental health problems.

In 2005, I returned to Nippon Medical School, Japan, where I established a child and adolescent clinic and focused on mood disorder and neurodevelopmental disorder. In 2014, I moved to Hokkaido University and started a new Department of Child and Adolescent Psychiatry.

Asako Tomioka(Psychiatric Social Worker)

I was trained in the Psychiatry Department, Fukushima Medical School and gained experience as an instructor in the Department of Social Welfare, Fukushima College. Also, I gained experience as a social worker in several facilities, including the psychiatry department and psychosomatic medicine department of a general hospital, a psychiatric hospital, a health and welfare center, a day care center, and a child support center. Since 2014, I have been working as a psychiatric social worker in the Psychiatry Department, Hokkaido University Hospital.

My work involves consultations with numerous patients (both children and adults) with diverse psychiatry problems, and with their families. In the child and adolescent psychiatry department where I am currently working, I offer support to the children and family members who visit our clinic, by striving to improve their conditions and minimize their problems. My work is carried out with the cooperation of various schools and institutions in the community. Our department started a new program for children with ADHD traits and their families last September. Since the program involves dealing with two groups (family members and children) in one room, it is challenging work. I am determined to keep trying my best, to listen to the participants’ opinions, and to make the program better and better.
