Beach Laboratory, Dr. Steven Beach

Director: Dr. Steven Beach

Some of the research in our lab has been examining the role of particular genotypes in moderating environmental effects on behavioral outcomes. Recently we have shown that genotype moderates effects of parenting on child outcomes, and that genotype moderates the effects of intervention of both parent and child outcomes. We are also examining epigenetic processes and their relationship to behavioral outcomes.

Personality Studies Laboratory, Dr. Josh Miller

The Personality Studies Lab studies the interplay between personality and psychopathology with a primary focus on externalizing (EXT) disorders and outcomes. Within the broad EXT grouping, our interest lies most strongly with the domain of Antagonism vs. Agreeableness. We see this as the core of multiple disorders including narcissism/narcissistic personality disorder, psychopathy/ASPD, and other related constructs (e.g., Machiavellianism). We tend to use structural models of general and pathological personality for much of our work (e.g. Five Factor Model/Big Five; DSM-5 AMPD) as we find it has great utility in organizing many of the constructs used in psychology and psychopathology with fewer concerns re: jingle-jangle fallacies.  We work on a variety of issues within this topic including diagnostic models of personality disorder, creating and validating assessments for these constructs, and building parsimonious empirical models of personality and psychopathology.

Vision Sciences Laboratory, Dr. Randy Hammond

Director: Dr. Randy Hammond

The primary goal of our research program is to conduct basic and applied studies on the visual system. A primary focus of the laboratory has been the study of the dietary carotenoids lutein and zeaxanthin, concentrated within the fovea (termed macular pigment or the macula lutea) and brain.  These studies have ranged across populations, infants to elderly, normal to diseased, and techniques, from pyschophysics to neuroimaging.

Multidisciplinary Team Reveals New Data on Alzheimer's Disease

Multidisciplinary Team Reveals New Data on Alzheimer's Disease

March, 2009

A multidisciplinary team of researchers from UGA (including Clinical Program professor L. Steven Miller), the Augusta VA Hospital, and the Medical College of Georgia have "revealed a direct relationship between two specific antibodies and the severity of Alzheimer's disease symptoms, raising hopes that a diagnostic blood test for the devastating disorder is within reach." Read about their work in the UGA Columns Newsletter.
