Studies the global structure of the Milky Way (bulge, bar, disk, spiral arms) using infrared and radio observations of stars and gas, and the evolution of galaxy groups via radio observations.

Buscher leads optical/infrared astronomical interferometry research at the Cavendish, co-leading COAST and serving as System Architect for the Magdalena Ridge Observatory Interferometer (MROI) in New Mexico. Current work focuses on MROI science-combiner instrumentation, fringe tracking, and light source/alignment systems for the beam train. He also holds an EPSRC grant (with Haniff and Young) on machining metre-sized gratings with nanometre precision for ELT high-resolution spectrographs. He is President of the Scientific Council of the European Interferometry Initiative.

Haniff co-leads the COAST and MROI optical interferometry program at the Cavendish. His work focuses on aperture synthesis imaging, fringe tracking, detector technology (EMCCDs, L3CCDs), and instrument design for the MROI. He also holds the EPSRC grating-machining grant for ELT spectrograph components. MROI achieved first light in 2025/2026.

Radio astronomer working on very-long-baseline interferometry (VLBI) and radio imaging instrumentation, including maser and stellar-envelope studies and computational methods for radio astronomy.

Directs the Laboratory for Astronomical Imaging; develops millimeter/submillimeter interferometric imaging instrumentation (e.g., for ALMA) and studies star and protoplanetary disk formation.

Studies the interstellar and intergalactic medium and galaxy evolution via radio observations of neutral hydrogen and molecular gas.

Studies molecular gas and the interstellar medium in galaxies using radio and millimeter interferometry (e.g., ALMA, CARMA).
