Dr. Arthur "Trey" Andrews III

  I direct the Latinx Mental Health and Treatment  Outcomes (LMHT) lab at the University of Nebraska-Lincoln.  I received my PhD in Clinical Psychology      from the University of Arkansas  in 2014.  I also did my clinical internship at the Medical University of South Carolina with a specialization in traumatic stress.  I continued this  work as an NIMH-funded postdoctoral fellow at the National Crime Victims Research and Treatment Center (also at the Medical University of South  Carolina).  Throughout my clinical training and clinical work I retained a focus on providing services  for Latinx immigrant populations.  The majority of  my clinical work has been conducted in Spanish. In  2016, I joined the faculty in the Department of  Psychology with the Clinical Training Program and the Institute for Ethnic Studies with Latino and Latin American Studies.  

 I am incredibly passionate about making sure that my research translates into positive impacts for my community.  This is reflected in my dual research aims.  I want to make sure that we not only understand why disparities occur for Latinx populations, but also make sure that we find solutions.  Similarly, I want to provide mentoring opportunities to individuals from underrepresented backgrounds and work to improve diversity in the psychology training pipeline.  When I'm not working on research or teaching, I enjoy traveling and spending time outdoors with my wife and daughter.
