This article on the Science Daily provoked a science reporter from KMOX
Radio 1120 AM in St. Louis, MO, to phone Phil Stewart for an interview.
KMOX is a 50,000-watt CBS affiliate that reaches 44 states with its
nighttime signal.
Other media that picked up the story of “Crustacean Compound
Fights Bacterial Biofilms”
included Forbes.com on September 11, 2006, and the ASM Weekly
News Digest, Issue #352
Coating common medical devices with an antimicrobial compound found in
crabs and shrimp might fight infection in hospital patients, new
research suggests. Read the full story at:

New Faculty Members
Matthew Fields has accepted MSU’s offer to join the faculty of
the Department of Microbiology and CBE. Matthew has been an Assistant
Professor in the Department of Microbiology at Miami University, Oxford,
Ohio, since 2003. He received his PhD. in microbiology at Cornell
University and completed his postdoctoral work at the Oak Ridge National
Laboratory. He will begin his new position in January 2007, as a faculty
member in the Department of Microbiology conducting research within the
CBE. Matthew’s talent for bacterial physiology and collaborative style
will make a great addition to the CBE. We are looking forward to working
with him.
Robin Gerlach has joined Montana State University's Chemical and
Biological Engineering Department as an associate professor. His
research focuses on using biofilms for the control and clean up of
contaminated soils and water. He will continue his association with
MSU's Center for Biofilm Engineering (CBE) and the Thermal Biology
Institute, where he conducts research related to biotechnology,
bioremediation and biofilms in porous media. Read the full story at:

Ailyn Lenz Receives ASM Graduate Research Fellowship
The American Society for Microbiology (ASM) has selected Ailyn Lenz
from Montana State University as a 2006-2009 award recipient of the
Robert D. Watkins Graduate Research Fellowship. Lenz is awarded up to
$19,000 annual stipend for three years to conduct research.
The Watkins fellowship seeks to increase the number of graduate
students from underrepresented groups completing doctoral degrees in the
microbiological sciences. The program is aimed at highly competitive
students who are enrolled in a Ph.D. program and have completed their
graduate coursework in the microbiological sciences. Fellows and their
mentors are required to be members of ASM.
Fellows will be required to present at the ASM General Meeting annually,
if their abstract is accepted, and to attend the ASM Kadner Institute,
formerly known as the ASM Graduate and Postdoctoral Summer Institute in
Preparation for Careers in Microbiology one time during the three-year
tenure of the fellowship.
Michael Franklin is Ailyn Lenz's mentor. The title of the research is
Localized Gene Expression Profiles of P. aeruginosa Biofilms in Respon.
The American Society for Microbiology (ASM), headquartered in
Washington, D.C., is the oldest and largest single biological membership
organization, with over 40,000 members worldwide. Please visit
