      abstract     = {Highly polarized, multi-kiloampere-current electron bunches
                      from compact laser-plasma accelerators are desired for
                      numerous applications. Current proposals to produce these
                      beams suffer from intrinsic limitations to the
                      reproducibility, charge, beam shape, and final polarization
                      degree. In this paper, we propose colliding pulse injection
                      (CPI) as a technique for the generation of highly polarized
                      electron bunches from prepolarized plasma sources. Using
                      particle-in-cell simulations, we show that colliding pulse
                      injection enables trapping and precise control over electron
                      spin evolution, resulting in the generation of high-current
                      (multi-kA) electron bunches with high degrees of
                      polarization (up to $95\%$ for >2kA). Bayesian optimization
                      is employed to optimize the multidimensional parameter space
                      associated with CPI to obtain a percent-level energy spread,
                      submicron normalized emittance electron bunches with $90\%$
