The TREES Summer Program would like to acknowledge the University of Pennsylvania’s Department of Systems Pharmacology and Translational Therapeutics and the Center of Excellence in Environmental Toxicology (funded by the National Institute of Environmental Health Sciences, NIH). The TREES Program is supported by Short Term Educational Experiences for Research (STEER) grant number 5R25ES016146 from NIEHS. We are also currently fundraising for the TREES program. If you know of any individual or organization that may be interested in contributing to our science outreach program, please email: ceet@pennmedicine.upenn.edu
