Brian W. Romans

Assistant Professor

I am a sedimentary geologist interested in reconstructing tectonic evolution, climate change, and fundamental sedimentary processes from the stratigraphic record. Although my focus is in the preserved sedimentary record, I am interested in the coupling of erosional landscapes (where sediment is produced) with depositional segments to gain a comprehensive understanding of Earth surface response to environmental change from centennial to multi-million-year timescales. My graduate school training was in both field and subsurface analysis, including >15 years of outcrop characterization. Since joining the faculty at Virginia Tech in 2011 I have added paleoceangraphy (via scientific ocean drilling) and geomorphology approaches to my overall program. My teaching interests are tightly coupled with my research interests; I teach courses in sedimentology-stratigraphy, sedimentary basin analysis, and related disciplines.

My group’s research interests are in the broad field of sedimentary systems with specific interests in clastic sedimentology, stratigraphy, tectonics of sedimentary basins, deep-sea sedimentary processes, paleoceanography, and paleoclimatology. We aim to understand the dynamics of sedimentary landscapes across a broad range of spatial and temporal scales using an integrated, source-to-sink approach. My students and I study ancient and modern sedimentary systems using outcrop, subsurface, and Earth-surface data to address geologic problems related to tectonic and/or climatic change as well as the relationship of intrinsic sedimentary dynamics to patterns observed in the stratigraphic record. Much of our research has implications for improving prediction and characterization of subsurface geology. Our current projects include: (1) foreland basin evolution and sedimentary processes from deep-marine slope (turbidite) systems, outcropping strata in southern Chile, (2) response of North Atlantic Ocean abyssal circulation to climate change at the Eocene-Oligocene transition, and (3) sediment flux history from stratigraphy in Pleistocene alluvial-lacustrine deposits, southeastern California.

There are currently four graduate students in the group:

  • Neal Auchter (Ph.D.) Stratigraphic architecture and evolution of deep-marine to shelf/deltaic deposits, Magallanes Basin, Chilean Patagonia, 2012-present
  • Kristin Chilton (M.S.) Response of the North Atlantic Ocean circulation to climate change at the Eocene-Oligocene Transition, Newfoundland Ridge drift complex, 2015-present
  • Sarah Jancuska (M.S.) Sedimentary processes and deposits related to slope system initiation, Magallanes Basin, Chilean Patagonia, 2014-present
  • Cody Mason (Ph.D.) Detecting signals of sediment supply in the stratigraphic architecture of outcropping Pleistocene alluvial deposits, Panamint Range, California, 2012-present

Since 2012, we’ve also had at least one undergraduate researcher working in the group every semester.

I teach courses in sedimentology-stratigraphy, sedimentary basin analysis, and related disciplines for both undergraduates and graduate students in geosciences. I strive to develop and teach courses that combine fundamental concepts and theory with hands-on experience working with sedimentary data of various types. Much of the content and exercises in my courses are relevant to the application of sedimentary geoscience to society, including energy exploration/production and Earth system response to environmental change.
