Everett Hayes '04 and Liz Yohannes grow cells for microarray hybridization studies of
pH-dependent gene expression. Arrays funded by our HHMI award, in collaboration
with Sandra BonDurant at the UW-Madison Gene Expression Center.
Summer of 2004.

Lab Group, 2000
Back row: Brad Hersh '94, back from MIT to present his research on C. elegans; Chris Kirkpatrick, research associate;
Prof. Slonczewski, NSF-funded research on E. coli and Helicobacter molecular biology.
Front row:   Sule Sidigu '03, Seena Mathew '02, Cat Beck '02.  Supported by HHMI 1996. .
Brad Hersh completed his PhD at MIT with Nobel laureate Bob Horwitz; now he studies fly wings on postdoc at UW-Madison.


Judy Phillips '00 won the Tomsich Award for her published studies of pH-regulated genes in Escherichia coli and Helicobacter pylori.  She found that anti-oxidant proteins such as AhpC are induced by acid.
She went to Cornell veterinary school.

Dani Barstad '97, Junior Honors, studying Mycobacterium marinum at the Rocky Mountain Lab, Hamilton, Montana.
She spent a year growing crystals for X-ray analysis, then went to dental school.
Chris Cave '96, completing thesis on the pilin operon lpf, in Salmonella.
Here's an EM of virulence pili on his strain; photomicrograph obtained by Fred Hayes at RML.

Lisa Lambert '96, completing thesis on the global response to benzoate at low pH, in E. coli. She ran her
first 2D gels at Fred Neidhardt's lab; now we run 2D'sat Kenyon.
Published in Journal of Bacteriology, 1997.

Farees Farooq '96,  physiological characterization of a new acid resistance gene, xasA.
Published in  Journal of Bacteriology, 1996.
Farees Farooq is now a physician at University Hospitals of Cleveland.
 

Devin Johnson '98, Sarah McGeorge '98, and Grant Schulert '00.  All studied extreme pH-induced
genes this year.  Grant used "arbitrary PCR" to obtain flanking sequence; he got the technique
to work here for the first time, with  help from alumnus Erik Zinser '94.


Founding Alumni of Bacterial pH Lab:


Lab Group 1994
Erik Zinser '94, left.  Published in J. Bacteriology an extreme base resistance in E. coli.  Harvard '01; now tenure-track at U. Tennesee.
Brad Hersh '94 middle. Discovered an extreme acid resistance gene, gadC, in E. coli.   MIT '01, on a Howard Hughes Predoctoral Fellowship. Now tenure-track at Clemson U.
