  Gravitational-wave astronomy offers not only new vistas into the realm of
astrophysics, but it also opens an avenue for probing, for the first time,
general relativity in its strong-field, nonlinear, and dynamical regime, where
the theory's predictions manifest themselves in their full glory. We present a
study of whether the gravitational wave events detected so far by the
LIGO-Virgo scientific collaborations can be used to probe higher-curvature
corrections to general relativity. In particular, we focus on two examples:
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 by the gravitational-wave observations analyzed.
