Research Statement

My primary research interests are the rotational and shape properties of asteroids using photometric data. I have carried out studies of minor planets throughout our Solar System from Near Earth Asteroids to Kuiper Belt Objects using direct observations as well as archival data from sky surveys. I am experienced at handling data from sky surveys and satellites with research publications using data from e.g. ATLAS, Pan-STARRS and Gaia. As further surveys come online producing ever-more data, archival projects will represent an excellent avenue for research. I am always keen to involve talented undergraduate students in my research.

I lead ongoing international collaborations to identify and observe 'extreme' asteroids, those with highly unusual shape or rotation periods, with collaborators in Europe, North America and Africa. This involves both direct observing and the use of sky surveys e.g. ATLAS.

In addition to survey work, I am an experienced observer with completed runs on the Isaac Newton Telescope (La Palma), ESO New Technology Telescope (Chile) , Lowell Discovery Telescope (Arizona, US) and the Vatican Advanced Technology Telescope (Arizona, US). My specific observing interests are aimed at the discovery and study of asteroids with ‘extreme’ shape or rotational properties.


I am a Visiting Assistant Professor at the Department of Physics at Lehigh until May 2024.
