Current Research Areas

Evaluating Food System Investments + Innovations

Some questions I'm interested in:

  • How can we build a food system of the future that's better for all people and the environment?

  • What scales of food system activities (local, regional, national, global) are optimal and in what situations?

  • Are food system innovations and investments always meeting their intended goals? If not, how can we improve?

Evaluating Food + Agricultural Policy

Some questions I'm interested in:

  • Are food and agricultural policies having their intended effects? 

  • What are the unintended consequences of food and agricultural policies?

  • What kinds of policies will increase food system resilience to shocks?

  • How can food and agricultural polices better support marginalized people?

Exploring the role of Democracy in Food Systems

Some questions I'm interested in:

  • What is the role of democratic organizations (e.g., cooperatives) in food systems?

  • Can democratic organizations in food systems help address food system stakeholder concerns?

  • What are the opportunities and challenges for democratic organizations and participation in food systems?

Reflecting on the Work of Higher Education

Some questions I'm interested in:

  • What pedagogical techniques are most effective for teaching about food and agricultural economics?

  • How do we alleviate disparities in terms of race, ethnicity, gender, and institutional type in how we do our work as applied economists?

  • What are the most effective models for interdisciplinary research and outreach to address wicked problems?
