In recent years I collaborate extensively with Prof David Clemmer from Indiana University, who is the leading expert in the field of Ion mobility spectroscopy. By joining the fields of action and ion mobility spectroscopy I hope to be able to understand the interplay between the structure and photo-properties of biochromophores. I am also very much involved in giving popular lectures about my work, Physics in general and Mathematical recreations to the general public – in hopes of promoting interest and love for science. Born in Jerusalem Israel, was always interested in Experimental Physics and Recreational Mathematics.

I Completed regular army service, and then proceeded to study Physics and Mathematics in the Hebrew University in Jerusalem. My MA and Ph.D degrees were performed in the Weizmann Institute of science under the supervision of Prof. Daniel Zajfman, where I studied cluster physics using ion beam traps. My post-doctoral work was conducted in the laboratory of Prof. L. H. Andersen in Aarhus University, where I was introduced to the field of action spectroscopy of biochromophores.

The goal of our laboratory is to understand the basic quantum mechanics behind the function of these molecules. We wish to understand how these molecules absorb light and what happens to the molecule following photoabsorption. We want to understand how the structure of biochromophore affects its absoprtion, and how absorption affects the structure of the molecule. In doing so we hope to arrive at better understanding of the physics governing light matter interaction.

Naturally biochromophores are found in the center of proteins, which are located on the membranes of cells. Our approach at arriving at a fundamental understanding of their properties is to measure the chromophores when they are completely isolated from their surroundings, in the gas phase. In doing so we can study their intrinsic properties and compare them directly with calculations
