I am a family nurse practitioner with expertise in both primary and urgent care.

In addition to the College of Nursing at WSU, I  hold affiliate appointments in Prevention Science and the OSU/OHSU College of Pharmacy.

I currently serve on the Oregon State Prescription Drug Monitoring Program Advisory Committee and the American Society of Addiction Medicine’s National Benzodiazepine Tapering Guidelines Committee. In January 2022 I became the Assistant Director of the Washington State University Center for Cannabis Policy, Research and Outreach ( In August 2023 I was elected to the WSU Faculty Senate as the Chair-Elect, and will assume that position in August 2024.

Research Focus

I have more than 20 years of experience in policy analysis and development at a state, regional, national and international level in addition to continuous clinical practice across the lifespan. My research concerns the interface between public policy and prescribing patterns as they relate to practitioner, patient and institutional factors.

My dissertation focused on the validation of competencies developed to enact statutory changes to Clinical Nurse Specialist prescriptive authority. These statutory changes first enabled and then expanded this authority in Oregon to include controlled substances. As part of my dissertation research and funding, I completed a four-year fellowship with the National Council of State Boards of Nursing’s Institute for Regulatory Excellence.
