I am a health services researcher and primary care physician focused on understanding and improving the inefficient, inconsistent, and frequently low quality delivery of health care in the United States. The overarching goal of my research career is to generate policy-relevant and clinically actionable evidence that can inform efforts to improve the quality, efficiency, and equity of health care delivery in the US. Specifically, I have focused on three areas of health care delivery of great importance to public health and policy: 1) prescribing of opioids and other high-risk medications, 2) the organization of primary and specialty care delivery, and 3) post-acute care and nursing homes. My research agenda is informed by my clinical experience as a PCP, which gives me a front row seat to the dysfunction of the health care system, including the trials my patients face navigating their care and the daily challenges my clinical colleagues work to overcome.
