Dr. Ostrander joined the faculty in 2003. Previously, he was an elementary school teacher, school psychologist and on the faculty at University of Minnesota and Georgetown University. He also was an AAAS Congressional Science Fellow and served in the Ways and Means Committee, where he played a significant role in shaping landmark mental health parity legislation. Since arriving at Hopkins, he has greatly expanded the role of psychology within the Departments of Psychiatry and Pediatrics. He founded the PMP program and its Post-Doctoral Fellowship training program. During his tenure, the program expanded from a single faculty member to a professional staff of ten that includes faculty, staff, and post-doctoral fellows. Members of the PMP program are assigned to the child psychiatry inpatient and day hospital service. In addition, the program is integrated with over 20 pediatric medical clinics (e.g., oncology, urology, GI, burn, nephrology, surgery, dermatology). His research was one of the first efforts to examine the relationship between ADHD and comorbid internalizing disorders (i.e., depression, anxiety). More recently, his research has focused on the intersection between medical illness and psychological considerations.
