Fabian Valentin is a 2025 Charles B. Rangel Graduate Fellow and will join the U.S. Foreign Service upon graduation. Prior to attending Princeton, he served as a legislative staffer for the U.S. House Committee on Homeland Security, addressing international security and illicit trade issues. He also served as an AmeriCorps VISTA with the City of Orlando. Outside of work, he volunteered for multiple nomination cycles on the Nobel Peace Prize Nominating Task Group of the American Friends Service Committee.

Josh was born and raised in Commerce Township, Michigan, a suburb of Detroit. Before attending Princeton, he worked as an Assistant Analyst in the Health Analysis Division of the Congressional Budget Office (CBO), where he contributed to analyses on prescription drugs, the Affordable Care Act (ACA), and long-term care. Prior to the CBO, Josh traveled the country campaigning for Joe Biden in five states during the 2020 presidential election. Josh is equally passionate about politics as he is about Detroit Lions football and can be found many Sundays rooting for his (suddenly good!) hometown team. He also plays the French horn and looks forward to exploring the biking trails near Princeton's campus. After Princeton SPIA, Josh hopes to serve in a role where he can use data and programming tools to solve pressing healthcare policy challenges, particularly at the federal level.

Allyson is from Lake Forest, California, and graduated from UC Berkeley with a B.A. in Public Health and a minor in Public Policy. Raised in an immigrant household, Allyson is passionate about creating solutions to health care challenges marginalized communities face. At an early age, Allyson’s father was diagnosed with a chronic health condition that required frequent interactions with the healthcare system; she became acutely aware of the high cost of healthcare and its disproportionate impact on BIPOC and low-income families. These experiences pushed her to explore health policy and its impact on the Latinx community as a student, leading her to participate in the Cal-in-Sacramento Fellowship and the John Gardner Public Service Fellowship. Upon graduation, she served as a Legislative Analyst at the California Health and Human Services Agency where she sought to advance policy that addresses the root causes of health inequality. After Princeton, she hopes to work in government promoting Latinx healthcare accessibility. In her free time, Allyson is an amateur boxer, runner, and reality TV enthusiast.

Ashley is from Toronto, Canada and is an innovative finance and international development practitioner. Prior to Princeton, Ashley worked at Social Finance U.K. on the international development team, supporting the design and launch of outcomes‐based approaches and innovative finance mechanisms across a range of sectors such as employment, water and sanitation, and climate. She started her career at a not‐for‐profit impact investment intermediary in Canada, where she led due diligence and investor relations. Following MPA1, Ashley completed her summer internship at the Green Climate Fund in South Korea, where she reviewed funding proposals for climate investments in developing countries. In her spare time, Ashley enjoys cooking and sharing a meal with friends, spending time outdoors, and teaching yoga. 

Born and raised in New Jersey, Karl is excited to return to the Garden State after stints in Nashville, Tennessee and Washington, D.C. Karl graduated from Vanderbilt University with a double major in Economics and Public Policy Studies. While in school, he spent over a year exploring local government as an intern in the Nashville Finance Department. After graduation, Karl worked as a Research Assistant at the Federal Reserve Board of Governors for three years as a member of the Stress Testing section within the Division of Supervision and Regulation. Here, he supported the Stress Testing program through his preparation of briefing materials and his work toward improving model accuracy in the face of changing accounting standards. Both at Vanderbilt and the Federal Reserve, Karl has demonstrated his passion for economics and personal finance education through his leadership of volunteer organizations that strive to make these topics more accessible to high school students. At Princeton, Karl is looking forward to honing his understanding of public finance and applying that understanding to a range of policy areas. Outside of the classroom, he plans to continue his quest to find the perfect sandwich, a quest hopefully made easier by New Jersey's famed density of delis and diners.
