Earth and Environmental Science
Funding environmental science research is critical for a healthy planet and healthy people. In late 2017, I began working in the field of research development. First, as a Research Development Specialist for Environmental Science at the University of California Santa Cruz, and now as Director of Research Development at San Jose State University.
Good science requires good communication to have any larger societal impact. Unfortunately, scientists generally don't focus on explaining what they do, and how important it is, to non-science types. In 2012, I decided to be the unusual scientist who jumped out of research to focus on communication.
Inspired by my love of geology, landscapes, and history, I created a start-up company, Mobile Ranger, that made mobile apps, blogs, and social media content. The goal was to “connect people to places” by telling compelling stories of place with information sourced from local science and history experts.
The guiding philosophy was that when people know the human stories and natural wonders integral to every landscape, they develop a personal connection to it, care more deeply, and have a greater desire towards stewardship of their local places and the planet.
As of late 2016, I am no longer actively creating content for Mobile Ranger but all the great stories are still available via our mobile app and our website.
My research, from 1997 - 2010, focused on terrestrial carbon cycling particularly in forests. The residence time of carbon in forest ecosystems depends on how carbon is allocated by plants and the rate of decomposition of plant tissues and their alteration products in soils. By taking advantage of changing atmospheric radiocarbon (14C) concentrations in the atmosphere due to testing of above-ground nuclear weapons in the early 1960's (often referred to as bomb-carbon), the cycling rates of plant tissues and soil carbon on timescales of several years to centuries can be estimated.
