Rowland is investigating integrative health care approaches to problematic substance use in the Netherlands, Portugal and Brazil. His goal is to better understand the public health approaches pioneered by the Netherlands and Portugal, followed by an investigation of how that model translates to a larger country, Brazil, that implemented a Dutch-style drug law in 2006. A graduate of Northeastern University in international affairs, Rowland was a legislative assistant for US Senator Angus King and an opioid response project manager for the state of Maine.
