I work at the interface of Astrophysics and Astroparticle Physics, and am interested in a variety of problems relating to the accretion process especially around black holes, both big and small.  I am a member of the Event Horizon Telescope (EHT) Collaboration, serving on its Science Council from 2016-2022 (Vice Chair from 2019), and now sit on its Science Board.  I also co-coordinate the Multi-Wavelength Science WG, and am a member of the Cherenkov Telescope Array Project.  I am currently co-PI of the ERC Synergy Grant “BlackHolistic” to better understand black holes of all scales, including building a new mm-radio dish in Namibia (the Africa Millimeter Telescope, or AMT) in partnership with the University of Namibia.  By augmenting the EHT array with the AMT we will be able to make the first movies of the event horizon region of a supermassive black hole, as well as use the AMT on its own to study transient black hole outbursts.
