In this thesis, we present three projects that each contribute to this goal in different ways. We study the mathematical structure of isolated black holes in the quadratic gravity theories dynamical Chern-Simons and scalar Gauss-Bonnett. Using the Killing equation and Newman-Penrose formalism, we analytically investigate the symmetries and categorize the properties of these modified black holes. Next, we turn towards waveform systematics because extracting information from gravitation wave signals requires sufficiently accurate waveform models. Through an injection and recovery campaign of binary black hole signals, we show that uncertainties in calibrated coefficients in phenomenological waveform models can substantially bias astrophysical parameters recovered during data analysis. We propose a method to mitigate these biases by including the coefficients as model parameters and marginalizing over them during parameter estimation. We show that this procedure significantly reduced biases at the cost of increasing statistical error.
