PHYSICS OF GROWING SYSTEMS
& PLANT BEHAVIOUR
WHAT WE'RE INTO
DYNAMICS OF PLANT BEHAVIOUR Organisms thrive in a harsh and fluctuating environment thanks to a variety of fundamental processes such as decision-making, adaptation, learning and collective behavior. These processes are based on the ability to compare environmental stimuli, either in time via memory, or in space by collectively sharing sensory information between organisms. Our lab aims to provide a mechanistic understanding of these phenomena, suggesting plant responses as a model system. We adopt a statistical physics approach, inferring underlying microscopic processes from observed macroscopic responses, and carry out experiments in house.
PHYSICS OF GROWING SYSTEMS A variety of biological systems are not motile, but sessile in nature, relying on movement resulting from continuous growth in the direction of environmental stimuli. For example, in their search for nutrients, plant roots and fungal hyphae change their morphology by growing differentially, and neuronal axons grow towards a chemical signal. The irreversible nature of growth, together with the inherent coupling between space and time, calls for a new physical description.
We observe complex macroscopic responses of plants to diverse stimuli
We infer microscopic stochastic processes from macroscopic responses
We use minimal modeling and numerical simulations to study observations

ART >< SCIENCE
Art installation in collaboration with artist Liat Segal
Part of the Exhibition "Plan(e)t" @ Genia Schreiber Tel Aviv University Art Gallery | January - July 2020
Curators: Dr. Tamar Mayer and Dr. Sefy Hendler
A field of robotic plants is positioned at the gallery space. Inspired by natural plant behavior, the large-scale shoots slowly move in response to the changing light. Tropism, plants’ motion in response to stimuli, is expressed by the carbon-fiber mechanical shoots as they follow the artificial magenta sunrises and sunsets.
The lab is opening up this fall, looking for curious and enthusiastic students!
