Project Details

Historically, Mick worked with the gas phase projects of the Stavros group, exploring the photoexcited dynamics of biologically relevant cromphores such as phenol and pyrrole derivatives using photoion/photoelectron velocity map imaging (VMI). Working from a 'bottom-up'approach, by studying molecules of ever growing complexity up to full biological molecules, the fundemental biophysical processes that govern the photostability of hese complicated biomolecules (such as whole DNA or biological/synthetic sunscreens) can be understood.

Mick is currently working on the design and construction of an exciting new laser lab in collaboration with the physics department which will propel his scientific focus from the gas to the condensed phase. This lab will include beam-lines for transient electronic absoprtion spectroscopy (UV/white light), transient vibrational absorption spectroscop (UV/IR), time resolved opitcal/terahertz spectrscopy and time resolved terahertz/terahertz spectroscopy. This wide range of experimental techniques will allow Mick and the Stavros and Lloyd-Hughes groups to propel their research into a vast array of new areas such as biophysics, catalysis and materials science. Alongside this experimental work, Mick also augments results with high level theoretical calculations.
