Vermeer Bonhomme is a graduate student in mechanical engineering, designing the next generation of ultra-low-noise suspensions for gravitational-wave detectors. His research supports the Cosmic Explorer observatory, which will extend the arm length of existing interferometers from 4 km to 40 km and increase suspended mass from 120 kg to over 2000 kg. Vermeer’s work focuses on modeling, optimizing, and prototyping precision suspension systems that isolate test masses from seismic and control noise while accounting for optomechanical coupling and scale-induced dynamic effects.
