I joined Mike’s group in January 2006 as a postdoctoral fellow, and after completing my postdoc in 2010 stayed in the group as a staff scientist. My work is focused on one of the most fundamental questions in cell biology - cell size determination. The understanding of the mechanism by which neuronal cells might determine the length of their axons can open new horizons in neuronal regeneration after injury. We proposed a new mechanism for axon length sensing (Rishal et al., 2012, Cell Reports), and I am currently involved in a number of projects aimed at elucidating the molecular basis of this mechanism. My M.Sc. and Ph.D. studies were done in Tel-Aviv University at the Sackler Faculty of Medicine. I worked under the supervision of Prof. Nathan Dascal who helped me a lot in my development as a scientist. In my Ph.D. thesis I explored the mechanism of basal activity of GIRK channels. In my private life I’m married and have two smart boys. I like to spend free time with my family.

Dr. Nataliya Okladnikov
Research Associate -
I did my M.Sc. in the Technion, Haifa working on the translation independent localization mechanisms of mRNA to the ER. My Ph.D. research aim is to uncover the molecular signature of growing axons, or in other words what are the molecular differences that make axons grow to different lengths?
I am focusing on mRNA localization and local translation of candidate length-regulating proteins in the growing axon and how they affect axon growth. -

Dr. Eitan Erez Zahavi
Senior Postdoctoral Fellow -

I am currently a 4th-year PhD student in Mike’s laboratory. I completed my undergraduate studies in 2019, at Lake Forest College, IL, USA, focused on molecular neuroscience and cell biology. I started my MSc studies at WIS in 2019, eventually joining Mike’s lab’ for the degree. During my MSc I primarily studied the anxiolytic effects of β-sitosterol in mice, and the paper regarding this project was published in 2021. Currently I am investigating the involvement of importin β1 in synaptic plasticity and memory, and the role of importin α5 in MeCP2 nuclear import, among other side-projects. My work is oriented towards integrating molecular and behavioral neuroscience approaches, studying problems bottom-up from the protein-transport level, and top-down by investigating intriguing behavioral phenotypes.
In my spare time I like to hike and am an avid photographer.
