Current Research

I investigate various aspects of Type-4 pili. These are filaments that bacteria use with various purposes such as attachment. One of my aims is to reconstruct a functional pilus in a non- pilated E. coli using genes from N. gonorrhoeae and P. aeruginosa. I analyze pili expression using transmission electron microscopy, immunofluorescence microscopy, and western-blot. Another project includes pili assembly in a cell-free system. In addition, I use crystallography to determine the structure of a type- 4 pili ATPase. Lastly, I employ bioinformatics to study how type- 4 pili protein families have co-evolved.
