Calibration of the Tully-Fisher Relations and Hubble Constant Sakai et al. 2000 ApJ in close collaboration with Jeremy Mould (MSSSO, NOAO), Shaun Hughes (Cambridge), John Huchra (Harvard), Lucas Macri (Harvard) and Robert Kennicutt (Arizona)

Surface photometry data for all the galaxies with Cepheid distances
21cm line profiles for all the galaxies (rotational velocities)
Calibrate B,V,R,I and H-band TF relations
Apply the calibrated TF relations to distant cluster data, determine their distances, and then determine the value of H0
understand the uncertainties in the value of H0
