Projects:

X-ray excited photoelectron spectroscopy for environmental science

We investigate multiphase chemistry of atmospheric relevance at the air-water and air-solid interfaces using X-ray excited electron spectroscopy at the SIM & Phoenix & ISS endstations at the Swiss Light Source (SLS) and the ALS at the Lawrence Berkeley National Laboratory.

Chemistry of confined water

The hydrogen bonding network of interfacial nano-confinements in clay. Clays are composed of crystalline aluminosilicate layers that may be held together by hydrogen bonds of embedded water. This project investigates the local chemical environment of ions in the interlayer space of clay and the structure of the hydrogen-bonding network at subfreezing temperatures.
