Weak Lensing with Galaxy Clusters

Weak lensing and galaxy cluster abundances are two of the cosmological probes considered to have the most power for upcoming surveys.  They have a natural connection via the use of weak lensing to calibrate the masses of galaxy clusters--a critical measurement in order to reach the promised precision of galaxy cluster cosmology.  However, there are a number of systematic effects that must be considered when making these measurements.  I will discuss some recent work in measuring galaxy cluster lensing signals and handling sources of systematic error in those measurements as well as in weak lensing measurements in general.
