My name is Zach Sickmann.

I am a sedimentologist and field geologist seeking full-time employment as an Assistant Professor or a Postdoctoral Fellow.

I am currently a Postdoctoral Fellow Affiliate and Lecturer at the Department of Geological Sciences | University of Texas at Austin | my UT Profile.

I received my PhD in Geological Sciences from Stanford University (2018). My undergraduate training included BS in Geosciences (Honors) from Trinity University (2012).

My research expertise includes

Basin Analysis, Convergent Margin Tectonics, Source-to-Sink Sediment Dispersal, Provenance Analysis, Sedimentology in the Anthropocene

My fundamental research interests derive from discerning the origin and preservation of signals and disturbances in detrital sedimentary systems. Sediment and sedimentary rocks record information on the dynamics of tectonics, climate, and in modern times, anthropogenic activity that can be teased out in a variety of ways. My research focuses on developing interpretive methods and models, rooted in underlying process and generally employing some component of provenance analysis, to better understand how to find and use this information.



I believe that the foundation of science education should be teaching problem solving though critical thinking. Therefore, my primary goal as an educator and an adviser is to use expertise in my field, sedimentology and tectonics, to create a learning environment focused on observation and discussion that leads to evidence based interpretations regardless of the specific field of application. My approach to this is shaped by the example of a number of excellent educators who I have worked with, and been advised by, through my own education and early career. From my early experience in the small, undergraduate-only department of Trinity University, through my grad school experience in the relatively small, highly research focused department at Stanford University to my postdoctoral experience in the large Jackson School of Geosciences at the University of Texas, the common thread for successful educators and mentors is always engagement and flexibility. Educators must be engaged with their subject matter and students and flexible in their presentation and discussion.

I have been very fortunate to get to travel across the world for my own research projects and to assist colleagues on theirs. These are a selection of photos taken on these travels that highlight the beauty of the places we as geologists get to work.
