A program of studying evolved stars from closure-phase measurements in the near-infrared is underway at the IOTA interferometer. Several cool stars have been observed in the H band with the three-telescope configuration of the IOTA. Angular diameters of these targets have been measured for the first time in the H band. The preliminary results from our studies of a sample of about a dozen Mira stars are presented in this paper.

This work was performed in part under contract with the Jet Propulsion Laboratory (JPL) through the Michelson Fellowship program funded by NASA as an element of the planet finder program.
