Porzecanski opened up a second act in his professional career in mid-2005 by becoming a full-time university professor of international economics, a shift in professional direction that was part of a generational handover by Wall Street pioneers in emerging-markets research who had also taken early retirement and started out on new career paths. Having taught economics on an adjunct basis at
Columbia University and
New York University, he was a visiting professor of economics at
Williams College in Spring 2005. He was appointed to the faculty of the
School of International Service at
American University as of Fall 2005, first as Scholar of International Finance and then, as of Fall 2007, as Distinguished Economist in Residence. In 2012, he was also named Director of the International Economic Relations M.A. degree program at SIS, a position held until August 2018. In mid-2021, after sixteen years, Porzecanski retired from his full-time faculty appointment. Besides devoting himself to teaching, mentoring and policy-oriented research in his field, Porzecanski has provided expert-witness and other consulting services to law firms and institutional investors, as well as to U.S. government agencies and multilateral organizations. 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 (2021-2025) by the think tank
The Woodrow Wilson International Center for Scholars. == Patient advocacy ==
