Sara is a Land and Atmospheric Science graduate student. She studies how exotic earthworms affect forest soil temperature. Sara is also a talented singer and likes to be engaged in building communities.

Sara DeLaurentis

Kyungsoo Yoo was born and raised in South Korea. After studying physics at Yonsei University, he went to U.C. Berkeley for his doctoral research in Ecosystem Science. He once wrote about the transition. After teaching at the University of Delaware for 4.5 years, he moved to Minnesota in 2010. He is currently a professor of soil science at the University of Minnesota, Twin Cities.

Tyler Baumann

Tyler is a Land and Atmospheric Science graduate student. He studies the invasion mechanisms and biogeochemical impacts of jumping worms. Tyler enjoys bird watching, cooking, and garden farming.

Azucena Sierra Garcia

Azucena is a Land and Atmospheric Science graduate student and a Fulbright Scholar. She studies mountain indigenous coffee farming in Oaxaca and Veracruz, Mexico. Her goal is to become a science voice for indigenous farmers.

Tristina Ting

Tristina is an Environmental Sciences, Policy, and Management undergraduate student. She studies the effect of earthworm weathering on lunar regolith. Tristina is also studying music and enjoys exploring the Twin Cities in her spare time.

Adam Williams

Adam is a Ph.D. student in the Bioinformatics and Computational Biology program. His primary research is the transformation of lunar regolith into soils to enable off-Earth agriculture. He works as a professional engineer, and in his free time enjoys traveling and the outdoors.
