Gravitational waves can probe general relativity in the extreme gravity
regime. We study how the events detected so far by the LIGO-Virgo collaboration
can probe higher-curvature corrections to general relativity, focusing on
Einstein-dilaton-Gauss-Bonnet and dynamical Chern-Simons gravity. We find that
the two events with a low-mass $m approx 7 M_{odot}$ BH (GW151226 and
GW170608) place stringent constraints on Einstein-dilaton-Gauss-Bonnet gravity,
${alpha}^{1/2}_{rm EdGB} lesssim 5.6$ km, whereas dynamical Chern-Simons
gravity remains unconstrained.
