Dr Greenwood’s research interests are in the areas of femtosecond and attosecond lasers and their applications in the study of ultrafast processes.

He has many years experience studying the interaction of ultrashort, intense lasers with atoms and molecules. This work has been fundamental in nature but is also be being investigated for practical applications in analytical science. In particular he has used these pulses to make some of the fastest observations ever made.

He has authored/co-authored more than 80 publications in the refereed literature. The first direct observation of attosecond electron motion in a complex molecule published in Science in 2014 has already attracted more than 200 citations. He has had numerous international collaborations with groups in Germany, France, Sweden, Italy and the USA.
