Dr. Palacios-Fest is a late Quaternary micropaleontologist  with research interest focused on the reconstruction of aquatic systems using invertebrates, calcareous and siliceous algae to determine environmental changes induced by climate change or human impact.  His main areas of interest include the semi-arid American Southwest and those around the world.  He has spent 30 years in reconstructing late Pleistocene and Holocene environmental records from the Chihuahuan Desert in Texas to the Mojave Desert and the Great Basin in Utah, Nevada and California.  His experience has taken him to work in semi-arid regions of Argentina and Chile, and tropical areas in Tanzania, Burundi (Lake Tanganyka), and Costa Rica.  Through his studies, Dr. Palacios-Fest, has reconstructed the dynamics of irrigation canal networks in Arizona.
TNESR provides a wide range of geoarchaeological and environmental services.  In 2010, the firm joined the Arizona Department of Transportation (ADOT) DBE Task Force and the Arizona Department of Environmental Quality (ADEQ).  Our recent entrepreneurial history has a deep background in Arizona where, since 1988, we have worked along-side archaeological firms across the state and abroad.  TNESR has been recognized domestically and internationally for its study of the physical environments where people settled in the past and its role in the reconstruction of prehistoric and historic irrigation canals, reservoirs, and other aquatic systems associated to archaeological sites.  We have also gotten involved in the analysis of modern aquatic environments impacted by humans.
