Abstract:    In quantitative photoacoustic tomography (QPAT) we aim at    reconstructing physical parameters of biological tissues from measured    acoustic data. We present here a reconstruction method for QPAT in    non-scattering media that allows the simultaneous reconstruction of the    ultrasound speed, the absorption coefficient and the Gr\"uneisen    coefficient with differential data. We show some numerical simulations    with synthetic data to demonstrate the performance of the method. This    is a joint work with Alexander Mamonov.
