Summary of past and current work

  • During my M.Sc. I examined the influence of seawater Mg/Ca ratio on the resulting ratio in mineralized shells of unicellular marine eukaryotes named foraminifera. My findings provided important insight regarding the biological influences on metal incorporation into shells of microorganisms (Segev and Erez, Geochem. Geophys. Geosys., 2003).

  • In my Ph.D. I undertook a challenging project aimed to reveal cellular processes that occur in dormant bacterial spores. I developed novel methodologies for molecular characterization of spores as they are inaccessible to common research approaches. My research revealed novel RNA dynamics in spores and transformed common knowledge of spore biology (Segev, Smith and Ben-Yehuda, Cell, 2012; Segev et al., Jbact, 2013).

  • During my Postdoctoral research I established a novel model system to co-cultivate micro-algae and bacteria. Through the unique combination of approaches from microbiology and Earth sciences, I characterized the chemical crosstalk and physiological processes that govern a dynamic interaction between the micro-alga E. huxleyi and the Roseobacter bacterium P. inhibens. I conducted field studies which successfully linked several of the laboratory-based observations to the environment. (Segev et al., eLIFE, 2016; Dashkova, Segev, et al., Algal Res, 2016; Segev et al., Jphycol 2016; Segev et al., PloS ONE, 2015).

  • As a new principal investigator, I am establishing a lab that focuses on the study of microbial interactions in the marine environment. One of my post-docs and myself have already published a paper about microbial interactions that lead to multicellularity in phytoplankton (Abada and Segev, 2018, Front Mar Sci).
