Jiayuan joined the Ph.D. program in 2022. Her research interests are primarily in public and development economics and covers policy topics including education, family planning, taxation, technology adoption and women’s empowerment. In her work, she applies the following lenses: First, how the way individuals perceive their identity shapes their behaviors and preferences. Second, how categories and norms, present in culture, language, and governmentality, structure opportunities for individuals.
She holds an undergraduate degree in philosophy from Edinburgh University and a masters degree from School of Advanced International Studies at Johns Hopkins.

Arielle Weaver joined the Evans School Ph.D. Program in Public Policy & Management in 2021. Broadly, Arielle’s research interests are aligned with addressing issues of social equity, access, and opportunity for marginalized populations with an emphasis on women of color. Arielle seeks to bring a critical lens to her research, drawing attention to racial disparities resulting from policy and the policy process.
Prior to beginning her Ph.D. studies, Arielle had a career in Student Affairs and has experience in the areas of residence life, student conduct, leadership development, and mentorship for women of color. Through that work, Arielle had the opportunity to develop, advocate for, and mentor women of color student leaders, which informs her current research interests.


Reed Humphrey entered the Evans School Ph.D. program in Public Policy and Management in the autumn of 2021. As a collaborator on the Managing Future Risk of Increasing Simultaneous Megafires project, which takes a convergent research approach to improving wildfire management, Reed has worked extensively with officials at the Northwest Interagency Coordination Center to develop decision support tools that exploit the connection between synoptic weather patterns and wildfire activity to support decision making around the allocation of wildfire suppression resources. Prior to joining the Evans School, Reed worked as a policy researcher on a variety of issues, from immigration to education to urban air quality. He holds an MPP from the University of Southern California and a BS in Economics from Virginia Commonwealth University.
Reed’s dissertation, Wildfire Risk, Vulnerability, and Migration in the Wildland-Urban Interface, focuses on the communities most affected by wildfire and on their ability to mitigate this risk. In addition to building on the methods currently used to assess the wildfire risk that communities face, the influence of urban-to-rural migration and social vulnerability on community-level risk mitigation are explored. Ultimately, this research aims to improve the targeting of federal and state grants to communities in need of assistance in mitigating the wildfire risk faced by their residents.
