Research Interests

My research interests include mechanisms and interventions for vasovagal reactions. Vasovagal reactions have an important impact on the medical system, deterring people from various procedures, affecting the blood supply, as well as providing a theoretical challenge. 

Other areas of interest include the recruitment and retention of blood donors, as well as stress, anxiety disorders, blood-injury-injection phobia, and pain.
