Since joining UNLV in 2005, I have mentored over 30 undergraduates in STEM related research projects. Many of these have secured scholarships for their studies. I have also advised 9 graduate students (3 in progress) on research projects in my laboratory and mentored 1 post-doctoral research fellow, Natasha Griffin. In addition, I help mentor several new faculty members in my School at UNLV.


Helen J. Wing is an Associate Professor of Molecular Microbiology in the School of Life Sciences at the University of Nevada, Las Vegas. She obtained her Ph.D. in Biochemistry from the University of Birmingham (UK) in 1997, where she studied transcriptional gene regulation in Escherichia coli. She worked with both Prof. Stephen J.W. Busby and Prof. John R. Guest in her first post-doctoral position, where she employed biochemical approaches to study transcription. In 2000, Helen moved to the U.S. to take a post-doctoral position with Marcia B. Goldberg M.D. at Harvard Medical School and Massachusetts General Hospital. It was here that she became interested in the transcriptional regulation of Shigella virulence genes and antimicrobial peptides. She joined the faculty at the University of Nevada, Las Vegas in 2005.
The primary focus of my research laboratory is virulence gene expression in the bacterial pathogen Shigella flexneri, the causal agent of bacillary dysentery, which is estimated to kill over 1 million people each year. All four species of Shigella harbor a large virulence plasmid, which carries most of the genes required to cause disease in the human host, including those required for invasion, type III secretion and actin-based motility, a process that allows bacteria to spread from one human cell to another. We are interested in the environmental cues, the timing and the molecular events that trigger the expression of virulence genes. We are particularly interested in the complex interplay between nucleoid structuring proteins, proteins that facilitate the packaging of DNA into tiny cells, and the transcriptional regulators of virulence in Shigella VirF and VirB.
