My research and teaching focus on understanding the nature and dynamics of Quaternary paleoenvironmental and paleoclimate change and landscape evolution, environmental geology and natural hazards. I have concentrated my efforts on two major geologic-geographic regions: 1) the Himalayan-Tibetan orogen; and 2) the western Cordilleras of North and South America. This has involved research on glaciation and climate change, surface processes and landscape change. To undertake this research, I apply remote sensing, field methods, and geochronology. I direct two Quaternary geochronology laboratories (see: https://lewisaowen.wixsite.com/main). I have also worked on archaeological sites to help examine the influence of climate and associated environmental changes on humans.
