Due to the unprecedented sensitivity of the Advanced LIGO--Virgo network, in less than ~5 years the field of gravitational-wave astrophysics has evolved from speculating about the properties of compact binary mergers to having an observed population that facilitates astrophysical inference. These observations encode information about their progenitor stellar systems ---...
I present the body of work I have pursued over the course of my doctoral study at Northwestern University. First, I conduct an analysis of the measurement abilities of distinctive LISA detector designs, examining the influence of LISA's low-frequency performance on the detection and characterization of massive black hole binaries....
