Ithaca, New York Area

With team members, used literature research and past work from AguaClara teams to design experiments to test rates of floc settling out of raw water solution. Used a process-controlled, lab bench-scale model of a water treatment plant to conduct experiments. Analyzed data, compiled final report and presented the results to other AguaClara project teammates.

Collaborated with teammates to determine most cost-effective and efficient greenhouse design for crops to replace the poppy industry in Afghanistan. Utilized thermal properties of materials, location and animal-generated heat in final design. Calculated thermal properties of greenhouse.

Co-represented Cornell Cooperative Extension at Empire Farm Days and other outreach events. Designed outreach posters, banners, and handouts for biofuels. Edited and revised the farmers’ handbook on the cultivation and harvesting of shrub willow. Maintained “Willowpedia” website. Fieldwork included weeding, trimming, planting and uprooting of shrub willow.
