Kati Szlavecz: I am Associate Research Professor at the Department of Earth and Planetary Sciences. I am a soil ecologist working closely with computer scientists in several LUYF projects. I like to listen to music and sing. I also volunteer in various environmental education activities.

Yulia Savva: I am a postdoctoral researcher in the Department of Earth and Planetary Sciences at Johns Hopkins University. I enjoy doing research in forest and soil ecology. I also love to go on hikes with my friends and jogging. [CV]

Lijun Xia: I am a graduate student in Earth and Planetary Science at Johns Hopkins University. I work with Katalin Szlavecz, studying trace gas emissions from soil. Now I work on how invasive earthworm activities affect the soil respiration and other trace gas emissions at Smithsonian Environmental Research Center.

Scott Pitz: I graduated from Johns Hopkins in 2004 and worked as an environmental consultant until spring of 2008. Now I am graduate student in the Soil Ecology Lab. Previously, I was a research assistant and provided support on the ecology side of LUYF projects. Outside of the lab, I enjoy all things water, triathlons, and traveling.

Chih-Han Chang: I am a PhD student in the Department of Earth and Planetary Sciences at Johns Hopkins University. I am interested in the taxonomy, phylogeography, evolution and DNA barcoding of earthworms, and the effects of earthworms on other organisms and the biogeochemical cycles though modifying the physical, chemical and biological properties of the soil. I started my study on earthworms in 1999 at National Taiwan University in Taiwan and my work at Johns Hopkins in 2009. (WORMs love EARTH)
