Department of Geological and Environmental Sciences
Faculty of Natural Sciences
My life before BGU:
I was born in Ramat Hasharon and studied at 'Alon' High School for Science and Arts finishing in physics and music as the two cores of course study. My academic education started at the Hebrew University of Jerusalem, in a dual track of geology and philosophy. I later moved to the US to study for my master's degree at the University of Oklahoma, where I ran experiments that simulated the movement on rock faults, which occur during slow creep or fast and dynamic earthquakes events.
I completed my PhD at the Washington University at St. Louis, Missouri, where I conducted experiments simulating flow in the Earth's deep mantle layer relating seismic observations to real mantle conditions.
In my post-doc position at Brown University (Providence, Rhode Island), I combined my experience from my master's degree and PhD to research minerals that have very unique properties – they both behave in a way that is reminiscent of flow (i.e., creep) but also behave in a fragile – brittle fashion (like in an earthquake).
"Under high confining pressure (like at large depths) the rock will not break but will plastically deform. In an analogy, people behavior may change significantly whether they are under no or high pressure"
I research the mechanical and dynamic features of the planet. The planet is a dynamic body, which includes plate movement on its outer part accompanied by earthquakes at the edges of the plates and the flow of the mantle below the plates.
My research deals with (1) the deformation processes at the plates boundaries, including earthquakes and movement along faults (for example the movement along the Dead Sea transform) and (2) understanding the processes of flow and movement below the plates of the system called 'plate tectonics'. Flows or faults in the planet's interior are actually the bedrock's responses to the forces bearing on them. In lab experiments, rocks are being pressurized and heated simulating the conditions deep in the Erath (~100 km) in order to understand what would their behavior be under these conditions. That allows us to understand observations connected to plate tectonics such as mantle flow and the conditions under which pressure is released in the form of an earthquake.
At BGU, I found a department that is dynamic, aspires to grow, with a combination of young and veteran faculty and I am very happy to join as a faculty member.
An insight from my research:
Rocks as we know them are a hard and brittle substance that may break and snap like a bent pencil (similar to an earthquake). However, under different conditions rocks can be distorted and change their shape like a weak playdoh (similar to mantle flow). The conditions of confining pressure play a crucial role in determining how would the rock "behave". Under high confining pressure (like at large depths) the rock will not break but will plastically deform. In an analogy, people behavior may change significantly whether they are under no or high pressure.
Something that doesn't appear on my resume:
I was part of the Hebrew University, Givat Ram, basketball team, and we won the championship in our division.
A source of inspiration:
When I think of inspiration, I think of philosophy and art, which were always a source of inspiration for me. But the truth is that I get most of my inspiration from friends and those close to me.
When I grow up:
I'll be in the NBA. When I grow up body-wise, right?
If I was not a researcher, I would:
open a restaurant.
Maccabi or HaPoel? HaPoel Beer-Sheva (basketball)
IPhone or Android? Android
Winter or summer? Summer
Tea or coffee? Both, it depends on my mood
Night or morning? See tea or coffee…….. it depends on what I drank that day
Game of Thrones or Breaking Bad? I am loyal to the Sopranos
