DESCRIPTION:We present a continuation method to compute all zeros of certa
 in harmonic mappings $f$ in the complex plane. While tracing the homotopy 
 curves of $f$ is done by a prediction correction approach\, the main diffi
 culty is to handle the bifurcations and turning points. To achieve this we
  study the critical curves and caustics of $f$. Moreover\, we illustrate o
 ur method with several examples and discuss possible extensions.<br> <br> 
 This is joint work with Olivier S&egrave\;te (TU Berlin).
