The second generation era of ground-based gravitational wave detectors has just begun, and the first direct detection of gravitational waves will hopefully occur in the near future. The inherent weakness of the signals we are looking for calls for template based searches where theoretical models of the gravitational waves are compared to the detector output. Although this process can lift signals out of noise that is many orders of magnitude larger than the signal, it requires computationally efficient and accurate models for the detector output. One of the current key limitations of gravitational waveform modeling for compact binaries is the lack of analytical understanding of the spin-precessional dynamics of the system. Spin-precessional effects arise from the interactions of the spins of the two binary components, and failure to efficiently model them could impact detection and completely ruin parameter estimation. In this talk, I will describe how the equations governing these precessional effects can be solved analytically. The resulting gravitational waveform including such effects can model spinning binaries of arbitrary spin magnitudes, spin orientations, and masses. I will also briefly discuss the implications of such a model for gravitational wave data analysis.
