Spring 2013 Newsletter | Biology | Marquette University




Hungry Planet: Stories of Plant Diseases, written by Gail Schumann and Cleora J. D’Arcy, has been chosen by Choice Magazine (a publication of the Association of College and Research Libraries) as one of their “Outstanding Academic Titles”. Dr. Gail Schumann, who retired from our department in December 2012, feels that part of success of her book is due to her time teaching Plants, Pathogens, and People at Marquette. Instructing this course led her to a  widened  view of the most successful topics that got students to think about the importance of understanding some basic biology.



St. Maurice ProteinDr. Martin St. Maurice’s use of imaging technology to create three-dimensional maps of molecules was featured in the latest issue of Marquette’s Discover  Magazine, which recognizes the research and scholarship taking place at the university.




Dr. Allison Abbott has been promoted from Assistant to Associate Professor.  Dr. Abbott began her appointment at Marquette in 2006, and studies microRNA genes in C. elegans development.

Description: Dr. Rosemary StuartDr. Krassimira Hristova, assistant professor of biological sciences, applies emerging trends in molecular and environmental microbiology to help understand and prevent the spread of contaminants. Her recent work focuses on methyl tertiary butyl, a gasoline additive that is one of the leading ground-water contaminants in the country. "By better understanding the enzyme pathways and genetic regulation of the contaminant biodegradation, we can help develop more efficient bio-remediation technologies for the cleanup of gasoline spills," Hristova says. She is currently researching the toxic effects of human exposure to metal nano-oxides, with the goal of engineering less toxic nanomaterials that reduce contamination of human cells, in addition to analyzing the spread of antibiotic resistance in the environment by anthropogenic -deriving from human- activities. Both studies have enormous potential to improve the health and safety of people around the world.
