Students

I seek to involve both graduate and undergraduate students in research. Paleoseismic, tectonic-geomorphic, and mapping projects I work on give students unique field experiences evaluating evidence of recent faulting in the landscape. Skills learned in this field of study are directly transferrable to earthquake hazard investigations and seismic source characterizations.

The Active Tectonics Lab at Portland State University is a mix of both graduate and undergraduate students, our lab group meets twice a month to discuss published papers, and our related research projects. Students meet with me for one-on-one research discussions in alternate weeks. I support students at all levels to attend professional meetings and present research.

Students work with me on both local and out of state projects in many capacities ranging from graduate research assistant, REU student, senior thesis students, McNair students, volunteer field assistant and more, if you are interested in working with me please see the Prospective Student section below.

Prospective Students:

Graduate Students: If you are interested in obtaining a graduate degree at PSU with research in the fields of active tectonics, paleoseismology and tectonic geomorphology please contact me to discuss the PSU program, the Active Tectonics research group, your research interests, background and relevant experience. Students from traditionally underrepresented populations in the field of Geology are encouraged to apply.


Undergraduate Students: If you are interested in pursuing a senior thesis or research project with me please reach out to me so we can talk about your research interests. If you would like to do a Geology Department Senior Thesis let's chat one calendar year prior to your anticipated graduation date, typically around the end of your junior year.  Students with a geology or earth science major/minor or students with a strong background in the Earth sciences are all encouraged to reach out about potential projects.  Students outside of these areas and majoring in a different field who are more broadly interested in earthquake hazard and communicating science are also encouraged to reach out to discuss a collaborative project with Dr. Streig. 

Note, if you would like your research project to count as your Honors College senior thesis, you must apply for or have achieved entry into the PSU Honors College before the end of spring term of your junior year.  https://www.pdx.edu/honors/
