Preliminary results on exclusive pseudoscalar meson production at JLab will be presented. These data were taken concurrently with dedicated Deeply Virtual Compton Scattering (DVCS) experiments in Hall A and with CLAS. The Hall A results have motivated a new round of experiments that will pin down the different contributions to the DVCS cross section and thus allow a better extraction of GPDs from the data. In addition, we will also perform a Rosenbluth separation of the longitudinal pi0 electroproduction cross section which, if the appropriate kinematic limit is reached, can be interpreted in terms of Generalized Parton Distributions. A parallel program of measurements with a deuterium target will also be described.
