Gene x Hormone Interactions.
In collaboration with Dr. Christopher Beevers and the Mood Disorders Laboratory at UT-Austin, my students and I have found that an interaction between baseline testosterone levels and polymorphisms in the promoter region of the serotonin transporter gene (5-HTTLPR) predicts a subject’s reaction to acute stress. This result has clear importance for major depressive disorder. A pre-print of this manuscript should be uploaded to this site soon.
Hormonal Influence on Early Detection Behaviors.
In collaboration with Dr. Steven Ristvedt (Washington University), my students and I are looking at the causes of symptom-underreporting. Who fails to report a potentially life-threatening disease symptom, and why? I am a paid consultant on this project, advising on endocrine profiles that potentially predict the likelihood of symptom underreporting. The aim is to identify these at-risk individuals, and then design health-based communications to increase the likelihood that they will seek professional help when a symptom arises.
Psychological Consequences of Hormone-Dependent Cancer Treatment.
In collaboration with Drs. Ian Thompson and Bradley Pollock of the University of Texas Health Science Center-San Antonio, and Drs. James Pennebaker and Chris Beevers of UT-Austin, my students and I are proposing an ambitious series of studies to examine the devastating consequences that result from chemical castration (a therapy that is used to treat metastatic prostate cancer). These consequences include feminization, chronic stress, clinical depression, and loss of marital intimacy. We hope that findings from this project will allow for the design of interventions to limit or eliminate these consequences.
Psychological Processes in Alcohol-Related Aggression.
In collaboration with Dr. Peter Giancola of the University of Kentucky, we are conducting a series of experiments that are testing the psychological mechanisms underlying alcohol-induced violent aggression, with the aim of designing interventions to reduce alcohol-related violence.
