About Me

Ph.D in veterinary science, M.sc in applied microbiology, scientist, microbiologist, microbial biofilm researcher. Currently performing my post-doctoral research at University of California Santa Cruz, focusing on survival strategies of Helicobacter pylori, with a particular focus on biofilm and genes associated with this mode of growth.

Experience

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.
