Professional aspect

In 2016, I joined Ariel University as a senior lecturer and principal investigator. My research interest is investigation of molecular and functional mechanisms of memory formation and its impairments by aging related cognitive disorders, as well as understanding fundamental aspects of information processing and storing by the neural system.  This is continuation of my research agenda started in 2011 as an independent investigator in Tel Aviv University. During the period of my research activity in Tel Aviv University, my research group made numerous significant discoveries: we identified functional protein expression networks, responsible for memory acquisition and consolidation in hippocampus, as well as for depressive-like behavior; moreover, we found a fundamental mechanism of early phase LTP expression via non-canonical AKT pathway and started decoding of the role of Abl kinase in amyloid beta 42 effect on spontaneous presynaptic release; we also showed correlation between Glur1 overexpression in hippocampus and altered long-term potentiation in depression mice model. In addition, my team designed and implemented an innovative method of in vivo electrophysiological recording from freely moving animal that is one of the most successful and highly appreciate system among the neuroscientists.

My previous projects, before becoming an independent investigator, were not directly related to my current research interests. As in case of my M.Sc and Ph.D. training I investigated biophysical and molecular properties of ion channels, whereas during my post-doctoral research I took advantages of the most advance high-throughput methodology (e.g. mass-spectrometry) in combination with in silico and conventional biochemistry and imaging to elucidate factors impacting peripheral nerve injury related axonal retrograde transport, which "informs" the cell body about the lesion. As a research associate I conducted mastered and conducted very interesting research in structural mass-spectrometry. All these different fields of research opened up new horizons enabling to think out of the box, link advantages of various scientific approaches and study biological phenomena in systemic manner and to be always open minded and easily accepting new ideas and approaches.

The research programs of my lab are very challenging since it endeavors to investigate the Holy Grail of the contemporary neuroscience. This daring attempt entails to employ divergent research methodologies, in many of which I have acquired experience. However since study is never ending for scientists, I consider that strong core of the team and collaboration is the best way to succeed. Strive for taking advantage of multidisciplinary approach strongly affected my choice for my group members. I am lucky that I assembled the core of the group with excellent cooperation with two senior scientists to solve conceptual and technical-methodological challenges. This core creates an excellent conditions for graduate and post-graduate students to learn, acquire experience and conduct research. I encourage cooperation in my lab. Excellence and skills are entry pass to the lab but ability to cooperate is a ticket to stay with us.


In January 2018, I was appointed as a chairman of the Integrative Brain Science Center - Ariel (IBSCA). I consider that advancement of Neuroscience research in Ariel University as my essential goal. My mission as the chairman of IBSCA to enhance existing connection between the neuroscientists in the University, encourage of initiation of new conjoint research project, to establish new collaborative network in the university and between the scientistic of Ariel University and other universitis and research institution in Israel and around the globe. Particular stess will be applied to interdisciplinary collaborations, to link between fundamental research to the applicative aspect of neuroscience, including interaction with medical branches and industry. The center will endeavor to bring the neuroscience research in Ariel University to the highest level as conducted in the top-notch universities. Beyond research projects, preparing and training of the future neuroscientists will executed by implementing of new educational advanced neuroscience study program. IBSCA will turn to the center of knowledge and experience sharing and dissemination, annual international conferences, weekly seminars of invited outstanding scientists will further broaden horisons of the students, post-doctoral fellows and investigators in the university. The center will also serve as a source of knowledge dissemination to the general population and conduct multiple social activities . It is very exciting time to be in the frontiers of neuroscience in Ariel University these times. 

Other interests


Sometimes it is very difficult to decide what to study since there are so much interesting things around us. Consequently, if we cannot learn everything fundamentally, we can for a personal interest to get deeper into different fields of science. So my interests involve:

  • Theoretical physics, namely, theory of superstrings, M-theory, theory of quantum gravitation and so on...

  • Computers: principles of operating systems functioning; network security

  • Biological anthropology

  • Geology and tectonics

  • History of the ancient world and medieval times

  • And some other small things...........


Neither scientist can be good enough if he works all the time. Permanent load is supposed to make us less creative and more technical, devoid ideas with limited horizon of understanding of things. Leisure is supposed to restart our biological computer, throw out garbage of unsuccessful ideas, replenish our mind and refresh our ability to work fruitfully further. If you do not think so, you lack imagination of scientist.

Hence, I have a lot of interests beyond the knowledge:

Hiking, rappelling, rafting, diving, martial arts, traveling, music, photography and an additional long list not to be shown....
