I am a geoscientist, electron microscopist, and planetary materials researcher whose work has spanned a wide range of disciplines, from micropaleontology and dinosaur paleontology to stable isotope geochemistry, mineral physics, and planetary science. Throughout my career, I have been fascinated by how processes occurring at microscopic scales can reveal the history of Earth, other planetary bodies, and the materials that shape them.
I earned my undergraduate degree in Geology from Beloit College, where I studied freshwater diatoms in the Connecticut River through a Keck Geology Consortium research project hosted at Wesleyan University. Following graduation, I participated in the Geological Society of America's GeoCorps program, serving as a Paleontology Geodatabase Technician for the Nebraska National Forests and Grasslands. I then completed my master's degree in Geosciences at Northern Illinois University, where I used stable silicon isotope geochemistry to investigate Antarctic diatoms from the Ross Sea as part of the ANDRILL project.
In 2017, I joined the EPIC-SEM facility within Northwestern University's NUANCE Center, where I now serve as Facility Manager. I oversee five scanning electron microscopes, manage facility operations and staff, and support a research community of hundreds of users across disciplines ranging from materials science and engineering to biology and Earth sciences. In parallel, I am pursuing a PhD in Earth and Planetary Sciences under the guidance of Prof. Steve Jacobsen. My research focuses on understanding how high-pressure minerals form in shocked meteorites using advanced electron microscopy techniques, including Transmission Kikuchi Diffraction (TKD). I also collaborate with NASA and industry partners to investigate lunar regolith as a resource for autonomous off-world construction, helping develop technologies that could support long-term human exploration of the Moon.
My work sits at the intersection of geoscience, planetary science, and advanced microscopy, combining interdisciplinary research, scientific leadership, and a passion for developing new analytical approaches that help researchers answer questions ranging from Earth's past to humanity's future beyond our planet.
In August 2026, I had the incredible opportunity to visit Hitachi High-Tech's Naka and Marine facilities in Japan. As the manager of a facility with three Hitachi SEMs, it was especially meaningful to see firsthand the precision machining, assembly, and engineering behind the instruments I work with every day. I also had the opportunity to meet with Hitachi engineers to exchange ideas about microscopy technology, automation, and future collaborations. A special thank you to Nina Steenmetz for spending the day with me and providing such a memorable tour—it was a wonderful opportunity to connect with the people and innovation behind these incredible instruments.
I've been coming to M&M for years, learning EBSD from many of the people in this community. This year, I had the privilege of organizing a symposium alongside them.
It was such an honor to host symposium C05: Innovative Approaches to Microstructural Analysis: EBSD, ECCI, and 3D Techniques Across Disciplines with Ben Britton, Stuart Wright, and Julia Deitz. I even roped my old boss, Ben Myers, into chairing the first session with me!
A huge thank you to all of our invited and contributed speakers for sharing your outstanding work. It was a fantastic symposium, and I learned so much from all of you. I hope we'll all find each other again in a similar symposium next year!
This year I organized my first symposium for the Microscopy & Microanalysis Conference in collaboration with colleagues from University of British Columbia, Sandia National Laboratories, and Gatan/EDAX. The symposium, Innovative Approaches to Microstructural Analysis: EBSD, ECCI, and 3D Techniques Across Disciplines, will take place August 2–6, 2026 at the conference in Milkwaukee, and will bring together researchers from academia, national laboratories, and industry to showcase emerging advances in electron diffraction, imaging, and three-dimensional microstructural characterization.
There is honestly nothing more meaningful to me than this paper plate award from the Materials Science Student Association (MSSA).
Running a busy SEM facility means there's always another email to answer, another user to train, another problem to solve. It's easy to leave at the end of the day thinking about everything you didn't get to instead of the people you were able to help.
This award was such a wonderful reminder of why I love what I do. It's never really been just about the microscopes, it's about the people who use them. Getting to work with such fun, curious, passionate, and talented students is the best part of my job.
Thank you to the MSSA for this incredibly thoughtful "Facilities Manager of the Year" award. It means more to me than you know. I did my absolute best not to ugly cry when I received it. ❤️ Thank you for letting me be a small part of your research journeys.
(Also... microscopy rocks! 🔬... because I'm also a geologist, get it? 😜)
In February 2026, I attended the very first Mineralogical Society of America meeting with my advisor, Prof. Steve Jacobsen in Tucson, AZ. I presented a poster on my research focusing on microstructural analysis of laser 3D-printed lunar regolith and had the opportunity to reconnect with collaborators, including Prof. Tom Sharp (Arizona State University), and spend time with Northwestern Professor Craig Bina. During the meeting, I also had the honor of chairing the opening scientific session and introducing the keynote speaker, Prof. Nancy Ross (Virginia Tech). The meeting was a wonderful opportunity to share my research, strengthen collaborations, and become more involved in the broader mineral physics and mineralogy communities.
One of my favorite collaborations during my PhD was working with Dr. Mike Barsoum to develop a new Near-Axis Transmission Kikuchi Diffraction (NA-TKD) approach for characterizing electron beam-sensitive zeolites. Together, we designed and built the custom "Goose" NA-TKD holder, which enabled high-quality crystallographic mapping in our Hitachi SU8700 SEM with Oxford Instrument Symmetry 3 EBSD with NA-TKD head while minimizing beam damage to these fragile materials. The work, published in Nano Letters, demonstrated how this new approach can reveal crystal orientations and defects that were previously difficult to resolve, opening new opportunities for studying beam-sensitive materials with electron microscopy.

I'm excited to share that my image "Crystal Raspberry" was selected as the Winner of the Materials Science category in the 2025 Oxford Instruments Insight Awards! 🎉
This image captures a tiny pyrite framboid from an Early Cretaceous sediment core collected from the Vocontian Basin in southeastern France. Using the Oxford Instruments Unity BEX detector, the elemental contrast highlights the iron- and sulfur-rich framboid surrounded by calcium- and silicon-bearing minerals. I used the Hitachi SU8700 SEM for this image.
