He has also served as a Dispute Resolution Arbitrator for the Financial Industry Regulatory Authority and was a Senior Associate at the think tank Center for Strategic and International Studies during 2007–2013. In July 2020, President Donald Trump appointed Porzecanski to the President's Advisory Commission on Hispanic Prosperity. Following his retirement from academia, he was named Research Fellow by American University's Center for Latin American and Latino Studies, and Global Fellow by the think tank The Woodrow Wilson International Center for Scholars. Patient advocacy Since late 2005, Porzecanski has struggled with an exceedingly rare illness, Systemic Capillary Leak Syndrome (SCLS), which left him partially disabled and brought him near death several times. He became an international advocate for those affected by the disease, setting up a website for patients, caregivers and physicians around the world to share information and provide support, and serving as its resident expert. He also persuaded the National Institutes of Health to carry out basic biomedical research on this syndrome. In early 2009, Porzecanski was profiled in the Health section of The Washington Post for this initiative and his determination to cope with this life- and limb-threatening illness. His leadership role as a patient advocate was recognized by Whittier College with an Outstanding Alumni Award for Community Impact. In 2016, the National Institutes of Health publicly acknowledged Porzecanski's “indispensable” role in spreading awareness of SCLS and in enabling NIH scientific research on the deadly disease. In 2018, Porzecanski won a lawsuit against the Secretary of the U.S. Health and Human Services Department in U.S. federal court, which overturned a Medicare denial of treatment with intravenous immunoglobulin (IVIG), a therapy which has become the standard of care for SCLS patients. Scholarship Porzecanski has published widely in the fields of international finance and Latin American economics, with scholarly chapters in several edited volumes in economics and law and articles in peer-reviewed journals such as Business Economics, Chicago Journal of International Law, Development, Ethics & International Affairs, Fordham International Law Journal, International Finance, Journal of Banking and Finance, Journal of Developing Areas, Journal of Money, Credit and Banking, Law and Contemporary Problems, National Tax Journal and, World Economics. His only scholarly, sole-authored book, "Uruguay's Tupamaros: The Urban Guerrilla", a contribution to political science, was published in the United States while he was a 23-year-old graduate student in economics. He has been a life member of the Council on Foreign
