Dr Denis Martynov works on the design of the future gravitational-wave instruments. In particular, he is interested in improving the LIGO detectors at low (< 20 Hz) and high (> 1 kHz) frequencies to observe intermediate-mass black holes and post-merger oscillations of neutron stars. The experimental effort of Denis’s group is also related to the future gravitational-wave detectors.
As a part of the Gravitational Wave Group, Denis develops a novel optical seismometer to improve seismic isolation of the future LIGO and Einstein Telescope detectors. Denis also builds a cryogenic prototype of the future instruments which will also be a testbed to study quantum motion of macroscopic mirrors.
