Dr Castellanos is Professor of Psychiatry and Pediatrics and Founding Chair of the Department of Psychiatry & Behavioral Health at the Florida International University Herbert Wertheim College of Medicine.  In 2008 he founded his Department as a part time faculty member along with a half time administrative assistant. Over the past several years he has led the rapid growth of his Department including the hiring of several key faculty members, the expansion of the clinical and educational programs, the establishment of research programs and the overall development of scholarly activity.

Today, the Department of Psychiatry & Behavioral Health is the second largest clinical department in the Herbert Wertheim College of Medicine. Twenty six salaried full-time and part-time faculty, four staff clinicians and over 60 voluntary faculty comprise the core of the Department.  Under Dr Castellanos’ leadership, the Department of Psychiatry & Behavioral Health is currently the one of the top recipients of sponsored research funding in the College of Medicine.  The Department’s faculty are the most productive in terms of scholarly activity (peer reviewed publications, presentations at national and international meetings). 

Education and training have been an integral part of Dr Castellanos’ vision and the Department’s mission.  In partnership with Citrus Health Network, Dr Castellanos and his faculty helped develop and obtain accreditation for a new psychiatry residency program.  The novel training program is the first ACGME accredited psychiatry residency program in the country based out of a Federally Qualified Health Center and a Community Mental Health Center.   Since 2015 he has also served as the College of Medicine’s Assistant Dean for Graduate Medicate Education (GME). As the Assistant Dean for GME Dr Castellanos works assisting regional hospitals in developing residency programs in different specialties.  Dr Castellanos is committed to developing programs that offer excellence in education, training, research, and clinical services.
