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.
