ATLANTA — Austin Castellanos’ (B.S. ’13, Ph.D. ’21) passion for economics was ignited by a class at Clayton State University. Eager to deepen his understanding of economics, he sought programs with advanced research opportunities and proximity to urban environments, prompting his transfer to Georgia State University’s Andrew Young School of Policy Studies for its more comprehensive economics program.
After transferring to Georgia State, Castellanos immersed himself in research opportunities that would begin to shape his future career. He worked as a research assistant for Andrew Feltenstein, now a professor emeritus of economics, focusing on sales taxes in Georgia using computer models.
“The assistantship opened my eyes to the practical applications of economic theory,” he said, citing the experience as a turning point in his academic journey.
In the final two years of his Ph.D. program, Castellanos worked for an economist at the Federal Reserve System through the Federal Reserve Bank of Atlanta Fellowship. He credits much of his internship success to the mentorship he received, particularly from professors Feltenstein and Garth Heutel. He also fondly remembers attending department seminars and meeting Ambassador Andrew Young.
“These interactions were all instrumental in helping me figure out my career path,” he said.
After graduation, Castellanos landed a position with the Congressional Budget Office (CBO) in Washington, D.C., where he has been working for the past three years. Now a principal analyst for the CBO, his role involves researching topics for Congress, such as the impact of clean energy policies on greenhouse gas emissions. His work has been published by the CBO, contributing to national policy discussions.
“By analyzing economic data and policies, I am able to provide insights that inform critical decisions at the highest levels of government,” he said. “It’s a responsibility I take very seriously.”
Castellanos’ achievements extend beyond his professional role. He recently co-authored the book “Computable General Equilibrium Modeling, Theory and Applications” with Feltenstein and another co-author. This collaboration reinforced his belief in the impact of academic relationships, and he emphasizes the importance of networking and engagement, especially for students.
“Reach out to your professors, network and meet new people in your field and attend as many extracurriculars in school as you can,” he said. “Building relationships with faculty and peers can provide invaluable support and insights that will benefit you throughout your career.”
