Mentoring Experience

Lauren Bunce (2018-2019) - Undergraduate, Stony Brook University


Scientific Visualization and Outreach

I am interested in processing archival spacecraft imagery for public outreach. I have independently developed image processing pipelines using the USGS’s ISIS3 software and custom Python scripts. These include tools for creating true-color imagery using Mars Reconnaissance Orbiter CRISM spectrometer data and flyover videos of the Martian surface using Mars Reconnaissance Orbiter MARCI data. Images that I have processed have appeared as press photos in the New York Times, Nature, National Geographic, and Astronomy magazine, among other outlets. My image processing work can be accessed at Flickr and YouTube. I have written several articles discussing my work for the Planetary Society (listed below).

Processed photos rendered from spacecraft data archives can be viewed on my Flickr page.

Rendered orbital flyovers of Mars can be viewed on my YouTube channel.


Grants and Awards

USGS-NAGT Internship (Summer 2012, Mike Cosca, Denver Federal Center) Competitive internship position with eligibility restricted to top three performers at an accredited geology field camp program. Preparation of mineral separates for Ar/Ar geochronology. Field projects included sample collection in the Sangre de Cristo range of Colorado and structural mapping of the Salmon River Canyon near Elk City, ID.

David E. King Field Award (Summer 2017, Stony Brook Department of Geosciences) Department award to fund graduate field study or research. Award was used for a multi-person graduate field trip collecting samples for laboratory research and to visit planetary analog field sites (inverted channel networks in Green River, UT; Upheaval Dome impact structure; Diagenetic features at Arches Nat'l Park and Snow Canyon State Park, UT; basaltic lava flows in SW Utah.


Other Work
