My interests lie in paleoclimatology - reconstructing past climates through the study of natural records, particularly the biogeochemistry of lake sediments. I am involved in the Lake El'gygytgyn Drilling Project in Northeast Siberia. The sediments of crater lake El'gygytgyn have been collected in order to gain high-resolution data stretching continuously over the last ~3.6 million years.

Also, take a look at Tim Martin's Polar Trec journal about a middle school science teacher's experience at Lake El'gygytgyn.
