While I am not a climate scientist, teaching environmental science and sustainability courses has made me a climate activist. My decision to write a book on environmental sustainability was motivated by my concerns about global climate change.
Every year my students and I calculate our ecological footprint, and air travel has accounted for a large portion of my carbon footprint. So I have reduced the number of scientific conferences I fly to by attending fewer conferences, by participating virtually, or by attending local or regional conferences I can drive to. This has reduced my travel costs, and increased the amount of time I can devote to research.
I study the geochemistry of trace elements in natural waters, sediments, and rocks; greenhouse gas emissions from volcanic calderas; and the behavior of trace-element enriched accessory minerals in igneous and metamorphic systems. I have also published a book on environmental sustainability.
