Gravity Wave Physicist
I have worked at BAS since 2006 and am now based with the Atmosphere, Ice and Climate team. My main area of research is the study of atmospheric gravity waves as a vertical coupling mechanism in the polar regions. I am also interested in space weather effects on middle atmosphere circulation.
I am joint PI (with Prof. Taylor of Utah State University) of two all-sky airglow imagers and am PI for 3 airglow spectrometers and a ship-borne airglow imager system. These instruments all observe airglow perturbations caused by gravity waves at around 90km altitude. I also use radiosonde data to study gravity wave activity in the lower stratosphere.
I am on the committee for the ANtarctic Gravity Wave Instrument Network (ANGWIN) which is an organisiation looking to study gravity waves across Antarctica using international collaborations.
