The WFC3 Infrared Spectroscopic Parallel Survey (WISP) is a large ( 700 orbits) HST program that uses WFC3 slitless spectroscopy to detect thousands of galaxies across a wide redshift range 0.3 < z < 2.3. I will present an overview of recent results on emission line galaxies, including a statistical determination of their dust extinction properties, the discovery of a new population of extremely strong emission-line dwarf galaxies, implication of the observed number counts for the EUCLID mission. I will also discuss an ongoing project to constrain the properties of passive galaxies at z∼1.5 from the combination of the WISP spectra and broad-band HST optical and Spitzer photometry.
