Who We Are


Dr. Raiker is a licensed clinical psychologist and Assistant Professor in the Department of Psychology. Additionally, he is the founder and director of the Program for Attention, Learning, and Memory (PALM) at Florida International University. He received his B.S. in Psychology as well as his M.S. and Ph.D. in Clinical Psychology from the University of Central Florida. Additionally, he completed his clinical internship training at the University of Mississippi Medical Center where he was the recipient of the 2014 Excellence in Research Award. He is a 2015 National Institutes of Mental Health CHIPS Fellow and has also been awarded a 2015 NARSAD Young Investigator Grant by the Brain and Behavior Research Foundation. Most recently, Dr. Raiker was selected to receive a 2016 CHADD Young Scientist Research Award. Additionally, he is a member of the editorial board of the Journal of Abnormal Child Psychology. His program of research focuses broadly on understanding neurocognitive dysfunction in individuals with Attention-Deficit/Hyperactivity Disorder (ADHD). Specifically, he is interested in the extent to which deficits in neurocognitive processes are associated with the functional outcomes (e.g., learning problems) experienced by individuals with ADHD and how knowledge about these deficits can be leveraged to improve treatment of the disorder. Currently, he is examining the interaction of multiple dysfunctional cognitive processes and their implications for the development of novel assessment and intervention strategies. Additionally, he is interested in incorporating additional levels of analysis (e.g., neuroimaging) to increase our understanding of the disorder.

Graduate Students

Mileini Picture

Mileini Campez, B.A.

Originally from Miami, I obtained my Bachelor’s Degree in Psychology from FIU in 2013 and am a third year Clinical Psychology Student. My goal is to become a professor at a university conducting research on the core neuropsychological deficits underlying Attention Deficit/Hyperactivity Disorder and their relation to treatment outcome. In my free time I enjoy attending cultural events such as art festivals, book fairs, and concerts which Miami has plenty to offer!

dsc_0017Kelcey Little, B.S.

I was born and raised in Florida and received my Bachelors in Psychology from the University of Central Florida in May 2016. I am now a second year Clinical Psychology student here at FIU. I am interested in the varying executive function deficits in children with ADHD and how this affects not only their response to treatment, but how, when combined with other factors, it can predict their performance. I am also interested in the difference between children diagnosed with ADHD and children diagnosed with ADHD as well as a comorbid externalizing disorder. I hope to continue on my research either at a university or research hospital after my completion of the PhD program here at FIU. In my free time I enjoy going to art festivals and doing photography.
