I am the UC President's postdoctoral fellow. I did my PhD at Oklahoma State University where I used field sedimentologic and structural, and remote sensing techniques to constrain the geodynamic evolution of an exhumed IntraCONtinental Sag (ICONS) basin.

Currently, I am doing a (U-Th)/He dating combined with paleomagnetic constraints to provide the necessary data for the testing of mechanisms for large scale exhumation following Neoproterozoic collisional orogenesis in the Arabian-Nubian Shield. Particularly, we are interested whether the extensive exhumation is related to Late Ordovician glaciation.

I am also interested in continental rifting and morphotectonics particularly in the East African Rift System.

I am an experimental high-pressure mineral physicist. My current research pursuits involve chemical mixing (and de-mixing) in planetary interiors and melting of materials at high pressures. I employ laser-heated diamond anvil cells and a variety of in-situ and ex-situ techniques to characterize material properties in order to understand planetary interiors.


I am interested in using meta-omics to reveal the in situ activities of microorganisms and phages (viruses that infecting Bacteria and Archaea) in natural and human-related microbiomes.

I am a geochemist and climate scientist working on the water and carbon cycles in terrestrial environments. My work includes studying the response of past and present terrestrial landscapes to changes in climate using modeling approaches, geochemical measurements, and field observations. Broadly, I am interested in the role that Earth's continents play in modulating habitable surface conditions over geologic time and in using sediments to reconstruct past changes in weathering and hydrologic fluxes over Plio-Pleistocene to Phanerozoic timescales.

I am interested in geodetic observations (GPS and InSAR) to characterize the crustal deformation around subduction zones and large strike slip faults. I mainly focus on aseismic transient processes such as slow slip events and postseismic relaxation. webpage

My research focuses on climate variability of monsoons and tropical storms. Investigating the interaction of tropical synoptic-scale systems and large scale ocean-atmospheric coupled systems is the general goal of my research.
