From 1999 – 2000 I worked at the University of Mainz, Germany, as a research scientist developing the microcontroller software for the miniaturized Moessbauer spectrometer MIMOS that later flew on the NASA Mars Exploration rover mission.
From 2001-2005 I worked as a research scientist at the Max-Planck Institute for Chemistry in Mainz, Germany. During this time I was the lead engineer for the alpha-particle-x-ray spectrometer (APXS) on the European Rosetta mission and the NASA Mars Exploration rover mission. From 2003-2004 I led the calibration of the APXS in Mainz and developed the data analysis software and calibration.
After the successful landing of both MER rovers in January 2004 I spent 3 months at NASA’s JPL during the primary mission phase to operate the APXS and analyze the data. In 2004 I led the successful proposal to NASA for the Canadian contributed new APXS for MSL, which is supported by the Canadian Space Agency.
In 2005 I joined the department of Physics at the University of Guelph, ON, Canada, as an Assistant Professor.
