Alex Sox-Harris has a Ph.D in Counseling Psychology and M.S in Statistics from Stanford University. He is Associate Director of VA Program Evaluation and Resource Center, tasked with monitoring the treatment of VA patients with Substance Use Disorders (SUD). He is also the Research Coordinator of the VA SUD QUERI, striving to improve the quality of care for patients with SUD through implementation research. His primary research program has focused on validating measures of SUD treatment quality and refining the processes by which quality measures are developed. He has also documented great variation in the application of consensus standards of SUD care within the VA system. He hopes to use his participation in IRI to develop implementation studies aimed at reducing this undesirable variation and, more broadly, to increase the SUD QUERI’s contribution to implementation science.
