Welcome to my website!

• I’m a Ph.D. Candidate in Economics at Mines Paris – PSL, CEDP, under the supervision of Prof. Daniel Herrera-Araujo. In March 2026, I visited the Harvard T.H. Chan School of Public Health as a Visiting Research Student.

• My research lies at the intersection of health, environmental, and welfare economics. My current work focuses on:
  • The monetary valuation of climate-related health risks
  • Equity-weighted benefit–cost analysis for public health policy
  • The health costs of extreme temperatures, with a focus on hospital congestion

• My work spans two large-scale international research projects — VALESOR and SWACHE — where I have collaborated with partners across a multi-country consortium, designed and managed international surveys, and applied economic valuation to environmental and chemical health risks.

• Feel free to reach out at maria.kostopoulou(at)minesparis.psl.eu — you can also find my CV here.

I’m drawn to work that speaks to policymakers and contributes to real decisions on environmental and health policy. Outside of academia, I sing in a choir and do theater — which, it turns out, are not entirely unrelated to presenting research.

What’s New
