The Rider: David Kroodsma

For the past two years, David has worked for the Carnegie Institution of Washington's department of Global Ecology, where he works on the Jasper Ridge Global Change Experiment. This experiment, which is located on Stanford University property, attempts to discern the effects of climate change on grassland ecosystems in California.

Before working for the Carnegie Institute, David attended Stanford University, where he studied physics as an undergraduate and received a masters in Earth Systems for studying climate change and, in particular, how carbon dioxide cycles through the biosphere. At Stanford, he also spent two years as a teaching assistant in the physics and Earth Systems departments.

But, what's with all the biking, you might ask. To read about previous bike tours, including a trip across the country with his father, take a look at some past rides.
