I teach physics at the University of Cambridge and I work on the design, construction and scientific exploitation of high-resolution and high-precision astronomical instruments.

I lead the Precision Instrumentation activity in the Cavendsh Astrophysics group and am the principal designer of the Magdalena Ridge Observatory Interferometer, an imaging interferometer under construction in New Mexico.

My book “Practical Optical Interferometry” was published by Cambridge University Press in 2015. Plaudits include:

”… a rare gem of clear and rigorous explanation …” Barry R. Masters, Optics and Photonic News

”… this benefits not only from Buscher’s technical expertise but also from his years of teaching. Practical Optical Interferometry is a wonderful resource that fulfills a long-standing need for advanced undergraduates, graduate students, and postdocs enticed by the prospects of sub-milliarcsecond spatial resolution.” Harold A. McAlister, The Observatory
