Dr. Wiklind has a background as a radioastronomer, working mainly at millimeter and sub-millimeter wavelengths, using molecular rotational lines as probes of the dense and cold interstellar medium in both nearby and distant galaxies. His current research, however, requires a full multi-wavelength approach, ranging from the UV through optical/near-infrared and far-infrared wavelengths. Dr. Wiklind has used the multi-wavelength approach to study the spectral energy distribution of high redshift galaxies in the HST CANDELS survey. This data is now being used to study galaxy formation and evolution. Dr. Wiklind is also using the ALMA observatory to study the molecular interstellar medium in high redshift galaxies using molecular absorption lines.
