Outreach with the Campus Middle School for Girls: We worked with the eight grade environmental science class at the Campus Middle School for Girls. We introduced the girls to concepts in water quality and environmetnal science, and explored the water cycle in an urban setting, along with human activities that influence water and environmental quality. Mentors included Angela Kent, and grad students Ariane Peralta, Sara Paver, Katie Amato, and Moni Berg-Binder. Our six-week long program concluded with a decision-making activity that integrated everything they had learned about environmental quality and the water cycle! See more photos here!

NEON Microbial Ecology workshop:

Angela traveled to the LSU campus in Baton Rouge, Louisiana to attend a microbial ecology workshop for
the National Ecological Observatory Network (NEON). NEON is developing a continental-scale research platform for discovering
and understanding the impacts of climate change, land-use change,
and invasive species on ecology. This project will gather long-term data on ecological responses of the biosphere to changes in land use
and climate, and on feedbacks with the geosphere, hydrosphere, and atmosphere.

At this workshop, microbial ecology researchers from all over the country gathered to meet with NEON planners to discuss approaches to integrate microbial biology with the ecosystem-scale science of NEON.

Friends from UW-Madison, University of Florida, University of Georgia-Athens and elsewhere were also at this workshop. See more photos from the NEON workshop.


EBI retreat:

Angela attended the Energy Biosciences Institute research retreat. This meeting brought together all of the research teams funded by the EBI. These researchers are located at UC-Berkeley, the University of Illinois, and Lawrence Berkely National Lab. This scientific retreat was the "kick-off" meeting for the new research and development organization that will bring together the disciplines of biology, the physical sciences, engineering, and environmental and social sciences to devise viable solutions to global energy challenges and reduce the impact of fossil fuels to global warming.

Angela presented preliminary results from our biofuels and sustainability project that was recently funded by the EBI. See more photos from the EBI retreat.





2008 ACES Global Academy:

Angela was selected to represent the Department of NRES in the 2008 College of ACES Academy for Global Engagement. The ACES Global Academy is a year-long program designed to heighten global awareness among faculty in the College of ACES. The class of seven "scholars" will spend a year learning more about the international resources available on campus, in the state, and nation that will enhance their teaching, research and extension missions. The goal of the program is to increase learning of the international realm, and heighten global engagement by faculty in the College of ACES.

The 2008 scholars include: Kent Rausch, agricultural and biological engineering; Miguel Gomez, agricultural and consumer economics; David Miller, animal sciences; Kris Lambert, crop sciences; Nicki Engeseth, food science and human nutrition; Angela Kent, natural resources and environmental sciences; Michelle Norris, UI extension educator.

The program activities begin in February when the scholars will meet with campus international leaders. The group will travel to Washington D.C. in early March to gain exposure to funding agencies and resources that can assist with international activities in higher education. Throughout the spring semester, the Academy will explore options for an interdisciplinary project theme which will allow them to creatively work together at a selected international site later this year.
