I am currently a senior lecturer at Tel-Aviv University, Department of Geophysics and Planetary Sciences.

Since 2007, I am a member of the gravity team of the Juno Mission.

My main research interests are: Planet Formation, Planetary Structure and Evolution, and Extrasolar Planets.

The discovery of planets outside our solar system opens an opportunity to learn about  planets as a class and to improve our understanding of the planets in our own solar system.

In my research I try to address the following questions:

Giant Planet Internal Structure:

What are the internal structures of Jupiter, Saturn, Uranus and Neptune?

How does differential rotation influence the planets’ interiors, and what are the

possible types of interior rotation? What can we learn from Juno about Jupiter’s internal structure and origin?

Planet Formation and Evolution:

What evolution scenarios can lead to the present-state of Jupiter and Saturn?

How do various physical processes affect planetary contraction?

How can we discriminate among giant planet formation theories? 

Extrasolar Giant Planets:

What are the possible internal structures of extrasolar planets?

What can their internal structures and compositions teach us about their formation?

Job Opportunities: I am currently accepting graduate students and postdocs.
