My thesis is focused on the calibration and practical application of the Mars Science Laboratory (MSL) Alpha Particle X-ray Spectrometer (APXS). I am specifically interested in understanding mineral phase effects on APXS concentrations as well as improving the K-value technique (published by Campbell et al., 2008) for identifying additional light elements in the APXS spectrum.
