About Me

I am a postdoctoral researcher at University of California, Santa Cruz and I am fascinated by bacterial biofilms. I earned a PhD in veterinary science and a Masters in Applied Microbiology. Currently a Posdoctoral scholar


Postdoctoral researcher

Univeristy of California, Santa Cruz
Since November 2016
Responsibilities completed
  • Investigating Helicobacter pylori biofilm formation and its potential role in pathogenesis in the lab of Dr. Karen Ottemann. I'm using transcriptomic and genetic approaches to identify genes associated with H. pylori biofilm growth. We also use mouse-models for H. pylori infections and imaging approaches (CSLM and SEM) to characterize the biofilm structure its components.

    1. Novel genes associated with Helicobacter pylori biofilm growth. S. Hathroubi and K. M Ottemann. In preparation.

    2. The Helicobacter pylori biofilm state involves multi-gene stress-biased response, including a structural role of flagella. S. Hathroubi and K. M Ottemann. 2018. mBio (published, DOI: 10.1128/mBio.01973-18)

    3. Helicobacter pylori biofilm formation and its potential role in pathogenesis. S. Hathroubi, S. L. Servetas, I. Windham, D. S. Merrell, K. M Ottemann. 2018. Microbiology and Molecular Biology Reviews (Published, DOI: 10.1128/MMBR.00001-18)
