Associate Professor, Earth Science Institute, The Hebrew University in Jerusalem, Israel
I am the Principal Investigator for the FlowTrans ITN research at the Hebrew University of Jerusalem and supervisor for the FlowTrans Experienced Researcher, Stanislav Parez.
Our FlowTrans research will focus on coupled pressure solution and brittle deformation.
My research focuses on coupled chemical and mechanical processes that control rock deformation. I study processes on relatively small-scales (e.g. pores, grains, or shear-zones of geological faults), and try to understand how these processes affect, interact with, and control large-scale geological phenomena such as compaction of porous rocks, and dynamics of landslides and earthquakes.
Often the underlying processes and feedbacks controlling these complex multi-scaled systems are not well understood, and I work on the boundary between physics and geology to unravel them.
I use mainly theoretical and numerical tools: in some of my work I develop new theories and new computer simulation techniques to probe the systems behavior (often discrete methods, in which complex large-scale behavior emerges spontaneously from simple small-scale interactions), while in other work I use known theories and methods to explain previously not-understood phenomena.
One of the important characteristics of my work is forging collaborations with field workers and experimentalists to provide an empirical foundation to my theoretical work. In this I am guided by a belief that earth-science research must be completely driven and constrained by observation. Detailed research in my group includes two topics (that often overlap) – the mechanics of fault zones and landslides and fluid-solid interactions in rock deformation.
