Research Experience

I am currently enrolled in the Ph.D. Pharmaceutical Evaluation and Policy graduate program under the direction of Bradley C. Martin, PharmD, PhD.  I am also a postdoctoral fellow in the T32 Translational Training in Addiction program and receive additional mentoring by Teresa J. Hudson, PharmD, PhD.  My completed research projects include psychometric evaluation using the Medical Expenditure Panel Survey in validating a health-related quality of life instrument in those with chronic, non-cancer pain and cost effectiveness analysis using Markov modeling in which I and my co-authors have evaluated the cost-effectiveness of anticoagulants used for the treatment of atrial fibrillation.  Lastly, I have also had experience working with big data using epidemiological analyses in evaluating the impact of rural residence on mental healthcare as well as whether or not the removal of a common opioid analgesic from the US market resulted in patients switching from opioids to non-opioid analgesics.

Research Interests

My research interests center around substance abuse, and particularly prescription drug abuse, in big data. My goals are to contribute to a better understanding of the predictors of prescription drug abuse, to evaluate the effectiveness of opioid treatment for chronic, non-cancer pain, and to help alleviate barriers for patients in obtaining effective treatment for substance use disorders. Currently, I am evaluating the effect of prescriber mandates implemented by prescription drug monitoring programs on opioid and non-opioid related drug overdoses and accidents. I am also assessing health-related quality of life among patients who have chronic, non-cancer pain and use opioids either chronically, non-chronically, or do not use opioids. Working with colleagues here at the Little Rock and Fayetteville UAMS campuses as well as from the University of California at Riverside, we are evaluating racial differences in opioid use and diagnoses of chronic pain among veterans. Other projects I am collaborating on include evaluating initial opioid episodes among opioid-naïve patients and likelihood and predictors of long-term opioid use as well as the development of an opioid use continuum framework.
