Prior to beginning federal service, Mark worked as a chemist in the Research and Development divisions at the IBM facilities in San Jose, California, and held a variety of other private sector jobs. As a USGS ecologist and research scientist from 1996 - 2008, he led studies that focused on threatened and endangered birds, and Southwest riparian habitats.

Mark has extensive experience in USGS science management and leadership, starting as Station Leader at the Southwest Biological Science Center (2005-2008), as Chief of Staff for the Western Regional Director (2008-2010), as Associate Regional Executive for the former Pacific Southwest Region (2010-2012), and most recently as Associate Regional Director in the Southwest Region (2012-2013).
