Past Trainees

Megan Lau, PhD

Meg completed her thesis in Molecular Microbiology and Microbial Pathogenesis in June 2013.  She defined the role of YbcL, a novel UPEC effector protein, in inhibiting neutrophil trafficking across the bladder epithelial surface. 

Jennifer Loughman, PhD

During her seven years (2006-13) as a postdoctoral fellow and staff scientist in the Hunstad lab, Jen dissected interactions between uropathogenic E. coli and human neutrophils, including UPEC effects on a host immunomodulatory enzyme, indoleamine 2,3-dioxygenase (IDO).

Tracy Nicholson, PhD, MPH

Tracy completed her PhD thesis work in our laboratory in the spring of 2010.  Her thesis detailed the role of the E. coli outer membrane protein A (OmpA) in UTI pathogenesis and described how intracellular UPEC pathogenesis provokes the innate immune response.  

Abigail Mapes, MA

Abby completed her MA from Washington University in 2013.  Her work examined exotoxin expression by colonizing and infecting Staphylococcus aureus strains, as part of a collaboration with the Fritz group and Dr. Julie Bubeck Wardenburg at the University of Chicago. 

Elizabeth Danka, PhD

Elizabeth completed her PhD (Molecular Cell Biology) thesis work in our lab in 2015, supported by an individual National Science Foundation fellowship grant.   She completed an NIH IRACDA postdoctoral fellowship with Dr. Peggy Cotter (UNC) and is currently on the teaching faculty of Whitman College in Walla Walla, WA.

Patrick Olson, MD, PhD

Patrick completed his PhD thesis in the Hunstad lab in 2016 as part of the Medical Scientist Training Program.   His work on a new animal model of male UTI was supported by the Infectious Diseases training grant (T32) followed by an individual NRSA fellowship (F30) from NIAID. He is now a resident in Medicine at Barnes-Jewish Hospital.

David Rosen, MD, PhD

David completed his postdoctoral work in December 2017, forging new avenues in the pathogenesis of pneumonia caused by Klebsiella.  He is currently Assistant Professor of Pediatrics and an independent investigator, funded by a K08 grant from NIAID.

Kelleigh Briden, MD

Kelleigh spent two years in the Hunstad lab as part of her Newborn Medicine fellowship, working on multiple projects including the evaluation of the urinary kynurenine-to-tryptophan ratio as a marker for UTI.  She is now part of the Newborn Medicine faculty at WUSM.

Lubomira Tothova, PhD

Fulbright Scholar

Luba spent six months in the Hunstad lab in 2018, coming from her home country of Slovakia.  She worked on sex-specific responses to therapeutic agents in UTI.
