Department of Physics

Dr. Amir Bashan is a Senior Lecturer at the physics department of Bar-Ilan University. He received his PhD in physics of complex systems from BIU under the supervision of Prof. Shlomo Havlin. He completed a post-doctoral fellowship in the Channing Division of Network Medicine at Harvard Medical School. In 2013, Dr. Bashan won the Israel Physical Society Prize for Best PhD in theoretical physics. In 2017, Dr. Bashan received the Faculty Fellowship of Azrieli Foundation for Outstanding Young Scientists.



The human gut microbiome is a home for trillions of microorganisms from hundreds of different types, which play a crucial role in determining our health and well-being. Unbalanced microbial communities are linked to diverse physiological disorders, such as inflammatory bowel disease (IBD), obesity, allergy and autoimmune diseases. Yet, restoration or even diagnosis of an unbalanced microbial community is challenging, mainly because these microbes live in a very complex dynamic ecological system, shaped by intense species-species and host-species interactions.


Recently, D. Bashan found that the gut microbial communities of healthy subjects follow consistent ecological rules (e.g. inter-species interactions) with a typical assemblage-to-abundance pattern. This new findings improve our understanding of the complex dynamics of microbial ecosystems and pave the way towards developing novel diagnosis and therapy methods.


We develop novel personalized therapeutic strategies based on microbial species interactions, that will steer an unhealthy microbiome of a patient to a new healthy state.


Our mission is to create a direct interface between theoretical ecology and medical practices. Considering the great concern due to the rising in antimicrobial resistance, ecological design of the human microbiome may be used as an alternative treatment for suppressing pathogenic infections in order to reduce unnecessary antibiotic administration.
