Biochemistry and Molecular Biology major, Joceline Helmbreck, honored as the first Difference Maker of 2022 by President Lovell

Joceline Helmbreck, a sophomore biochemistry and molecular biology major in the Klingler College of Arts and Sciences, experienced great loss at a young age when her sister, Jessie, passed away from Ewing’s Sarcoma. Her life was so deeply touched by this childhood cancer that now she is using her talents to help find a way to ensure others can avoid that pain. Together with Dr. Nicholas Reiter, assistant professor of chemistry, Joceline is engaging in groundbreaking research to honor her sister’s memory.  Learn more about Joceline’s story in this feature from Spectrum News.

Two Biological Sciences Faculty Join the In Defense of Water Research Team

Two faculty members from the Biological Sciences departmentDr. Krassi Hristova and Dr. Chris Marshall— have joined the research team for the In Defense of Water program. Supported by Marquette’s largest-ever federal award for water research, this multidisciplinary research program brings together collaborators from Marquette and the U.S. Army Engineer Research and Development Center to address water quality challenges and promote healthier environments for troops and civilians. The projects will help the Army promote sustainability, resilience and health on and around military sites — and yield important public health benefits as well. We congratulate Drs. Hristrova and Marshall on this accomplishment. To learn more about their research, click here for the full story

GAANN Fellowship Funding

The Department of Biological Sciences has received a grant from the U.S. Department of Education to establish a Graduate Assistance in Areas of National Need (GAANN) Program. The GAANN program provides fellowships (stipend and tuition) to doctoral students of superior academic ability in financial need, particularly from traditionally underrepresented backgrounds in the field of biological sciences.
