Presenting at an Alumni College Session at Ohio Wesleyan University in 2014

The second issue of the Journal of Environmental and Resource Economics at Colby (JEREC) is now online.

I am an environmental and resource economist working as an Assistant Professor in the Economics Department at Portland State University. I also hold a "by courtesy" Research Consultant position at IUCN-Sri Lanka.

My main research is focused on studying the intersection of land use, ecosystem services, and conservation. I use choice experiment surveys to analyse public preferences for ecosystem services and environmental policy, and dynamic and spatial resource allocation models to study optimal land use.

My research applications focus on

  • grasslands in Illinois
  • riparian ecosystem services in Oregon
  • REDD+ payments in Nepal and Ethiopia
  • coral reefs in Okinawa, Japan
  • improved stove adoption in Ethiopia
  • conservation within military installations

In addition, I am also currently working on

  • preferences for sustainable seafood labels
  • spatially explicit subsidies for renewable energy generation
  • general equiblirium models of environmental taxation
  • dynamic models of economic systems using Stella
  • optimal school districting using integer programming methods
