My CV
     

Positions

I am a principle investigator at Migal and a senior lecturer at Tel Hai College.
     

Scientific Bio

      I study microbial communities in natural environments. Specifically, I am interested in understanding the dynamics of microbial communities over time with emphasis on strain variation and its role in species evolution and in maintaining community stability. To achieve these goals I use metagenomics, in which DNA is extracted from the environment and then sequenced. Methods and tools for analyzing metagenomic next generation sequencing data are mostly lacking due to the quick changes in DNA sequencing technology; however, my strong computational background allows me to develop the tools and strategies that are required for analyzing my data. These include, for example, methods for reconstructing genomes from metagenomic data, algorithms for strain-level binning of time series metagenomic data and more.

      I did my PhD with Prof. Oded Béjà and Prof. Ron Pinter at the Technion (Israel) and focused on the study of cyanophages and their hosts in marine environments. During my postdoc with Prof. Jill Banfield at UC Berkeley I have studied microbes inhabiting the human gut, in particular during the process of microbial colonization of the infant gut. Recently I've been working on microbial communities in groundwater sediment focusing on community structure, dynamics and interaction in this complex environment.
