My work

What I study?

I have worked extensively with modeling complex multilevel data to study a wide range of psychosocial, psychiatric, and substance use-related research questions in both large epidemiological surveys and administrative records. Below are selected research papers on a range of topics, including the health effects of prescription drug monitoring programs (PDMPs), cannabis legalization, diversity and inclusion, and military mental health.

Prescription drug monitoring programs (PDMP) have been advanced as a critical component of addressing the US drug poisoning crisis. My research has found little evidence PDMPs reduce drug poisonings, and potentially unintended increases in heroin poisonings.

Since 1996, 34 states have passed medical cannabis laws,, and since 2012, 11 states have passed recreational cannabis laws. While potential benefits of these laws exist, more research is needed to identify and mitigate unintended harms


I’ve worked extensively with military populations, including both active duty (US Army, Navy, and Marine Corp), National Guard (Ohio National Guard), and Veterans. Below is a sample of this work

Diversity and Inclusion

In the Summer of 2018, we conducted a web-based survey of members of the Society for Epidemiologic Research (SER) to assess perceptions of diversity and inclusion within the society. We found that women and persons of specific racial/ethnic minority or minority religious affiliations were less likely to participate in events initiated by the Society. These data represent a baseline for assessing trends and the impact of future initiatives aimed a improving diversity, inclusion, representation, and participation within SER.
