I am an infrared astronomer who specializes in measuring the polarization of
light. This type of observation can reveal the structure of dust in comets,
the magnetic field geometry in galaxies and pinpoint the location of hidden
stars. Specialized observing procedures are required, but a few major
facilities such as the NASA IRTF and the Hubble Space Telescope have a
polarimetric capability I am able to use. We are building a precision infrared
imaging polarimeter for use on the MMT in combination with the AO secondary.
