DESCRIPTION:ABSTRACT:Accurate signal models are essential in the analysis 
 of gravitational wave events\, from parameter estimation to astrophysical 
 interpretation and tests of general relativity. As detectors get increasin
 gly advanced it becomes ever more crucial to develop precision models of s
 ignals from a wide range of physical systems\, including black-holebinarie
 s where the spins are not aligned with the orbital angular momentum— pre
 cessing binaries. Evidence for a population of such systems has already be
 en seen during the third observing run of the LVK and this is expected to 
 become stronger in the upcoming run. I will discuss recent developments th
 at have resulted in the first complete inspiral-mergerringdown model of th
 e gravitational wave signal from a precessing binary where the precession 
 effects have been tuned to numerical relativity through merger and ringdow
 n as well as a more complete understanding of the phenomenology of such sy
 stems.
