I have supported a number of Mars missions, both as a member of the Navigation Team, as a member of the Navigation Advisory Group for the mission, or from my jobs in the Deep Space Network and the Multi-mission Ground Systems and Services office.
I am the Navigation Team Chief for the Mars Science Laboratory.
I was a member of the Phoenix Navigation Team, as an orbit analyst and shift lead during final approach. I also participated in the development and checkout of the Next Generation Navigation Software that was used, for the first time by an operational mission, by Phoenix.
I supported the Mars Exploration Rovers during their cruise while working as the Tracking and Navigation Service Development Engineer for the Deep Space Network.
My first job as a JPL employee was as an Orbit Determination Analyst for Mars Odyssey. I supported the final approach, the aerobraking phase, and the acquisition of the science orbit, contributing to the final design of that orbit.
