Research Interests    

Dr. Iñiguez' research focus is on the developmental neurobiology of mood-related illnesses, such as anxiety and major depressive disorder. To do this, his preclinical research program comprises a multidisciplinary approach (i.e., behavioral, molecular, and pharmacological) to examine how juvenile exposure to stress and/or psychotropic medications (i.e., fluoxetine, ketamine), influence sensitivity to drugs of abuse (i.e., cocaine), as well as memory-related performance, later in life.
