Engineers Without Borders at MSU one of four finalists for $20,000 national award
Mentored by CBE faculty member Otto Stein, professor, civil engineering, Montana State University's student-led chapter of Engineers Without Borders (EWB at MSU) has won one of four W.K. Kellogg Outreach Scholarship Awards.
The Association of Public and Land-grant Universities announced the regional award, which recognizes EWB at MSU for its work in bringing clean water to Kenyan schools. The recognition also puts the chapter in national competition with community outreach programs at three other universities—Michigan State University, Pennsylvania State University, and the University of Tennessee Knoxville—for the C. Peter Magrath University/Community Engagement Award. The Magrath award carries a $20,000 prize.
CBE undergraduates in chemical and biological engineering who lead the EWB, MSU chapter, include: Kiera McNelis, president; Joseph Thiel, vice-president; and Bryan Vadheim, treasurer.

Three CBE undergrads recognized among MSU's top students
Three CBE undergraduate students —Kiera McNelis, Hilary Fabich, and Joe Thiel — were among forty-six students honored this spring during Montana State University’s 88th Day of Student Recognition. The award honors achievement in the areas of leadership, involvement in various campus-wide activities, and community service.
Kiera McNelis, a junior in chemical and biological engineering, received the Roskie Memorial Award. The award goes to one undergraduate student who has shown outstanding leadership qualities. McNelis is the president of Engineers Without Borders and will travel to Kenya this summer as a project manager for EWB. McNelis' parents are Kevin and Marilyn McNelis.
Hilary Fabich, a senior in chemical and biological engineering, received the Ethelyn C. Harrison Award presented to a senior woman who exemplifies high standards and concern for others. Fabich is a member of Engineers Without Borders, the MSU Symphony Orchestra, and has been an undergraduate researcher in the Magnetic Resonance Microscopy Lab for more than three years. Fabich's parents are Hank and Adrienne Fabich.
Joe Thiel, a junior in chemical and biological engineering, received the Christy Foundation Scholarship awarded to a student who has brought special recognition to MSU based upon meritorious community leadership and service. He also received the University Honors Program Leadership Award. In addition, Thiel was inducted into Septemviri. This senior honorary recognizes seven outstanding juniors based upon extraordinary scholarship, leadership and service to MSU. Thiel is the president of Phi Kappa Phi, the vice president of Engineers Without Borders, and an ASMSU Senator. Thiel's parents are Greg and Liz Thiel.

Dr. Bart Lomans, Microbiology and Biotechnology Specialist for Shell Exploration and Production, visited the CBE June 7, 2011. The purpose of Dr. Loman's visit was to develop collaborations with CBE associated faculty Al Cunningham, Robin Gerlach, and Matthews Fields in the areas of biomineralization applications and subsurface issues, as well as microbially enhanced coal bed methane production.
Visiting Student Researchers
The MSU Algal Biofuels Group is working with five Native American students and staff from Little Bighorn College (LBHC) during a ten-week project titled “Cultivation and Characterization of Oil Producing Algae.” The project is funded by a collaboration of commercial, state, federal, and tribal entities focusing on the development of “Green Coal to Transportation Fuel Technology.” The project with LBHC involves training students in the use of algae as a means to capture carbon dioxide and produce biofuels. The specific objectives include collection of algae from natural field sites, isolation of pure cultures, building photo-bioreactor systems, characterizing algal growth in these systems, and measuring oil productivity. The participants from LBHC, located in Crow Agency, Montana, are: Jonah Morsette, staff member, and undergraduates: Zachary Cummins, Elaine Stone, Miranda Rowland, and Amanda Not Afraid. CBE mentors on the project are Brent Peyton, professor, and Rich Macur, research assistant professor, both of MSU's Department of Chemical and Biological Engineering.
Three undergraduate students are working at the CBE as part of the American Indian Research Opportunities (AIRO) BRIDGES program. The program’s objective is to build a seamless educational experience between reservation-based colleges and Montana State University and, in the process, increase the number of underrepresented Native American students successfully transferring from the two-year tribal colleges to MSU and pursuing academic studies in the biomedical and other health-related sciences. The students are working at the CBE for eight weeks and then traveling to Old Greenwich, Connecticut to present posters of their work at the Leadership Alliance National Symposium.
Adrianna Collazo Ortiz, undergraduate, University of Puerto Rico San Juan, is studying pathogens and constructed wetlands with CBE faculty Mark Burr, Research Assistant Professor, Land Resources and Environmental Sciences.
Jeremy Richey is working on a dentistry project under the supervision of CBE Research Scientist Alessandra Agostinho titled “Testing of Denture Base Materials Incorporated with Silver Nanoparticles to Prevent Candida Colonization.” Jeremy is an undergraduate student from Fort Belknap College in Harlem, Montana.
Kendra Teague is working with Heidi Smith, CBE PhD candidate, Land Resources and Environmental Sciences, on a project that characterizes Antarctic isolates based on different carbon source utilization. Kendra is an undergraduate student from Fort Peck Community College in Wolf Point, Montana.
Ann Willis, CBE Technical Operations Manager, led a CBE lab tour for fifteen advanced placement biology students from Belgrade and Three Forks high schools. The students asked lots of questions as they toured the bioprocess and algal biofuel labs and viewed biofilm images and cryosectioning through CBE microscopes. We look forward to their return as biofilm reseachers in the future.
Accepting applications: New biofilm online course
Starting in fall 2011, the University of Copenhagen is offering a new online course: “Bacterial Biofilms and Their Role in Chronic Diseases”. The course can be followed by both masters degree and PhD students, as well as professionals that meet the admission criteria. For registration and more information, please visit: http://www.biofilmcourse.ku.dk Application deadline is August 8, 2011.
