Skills
I have spent 10+ years designing and executing robust experiments to observe real world processes and perform accuracy assessments of sensors and new methodologies against ground truth data. I have a strong understanding of statistical analysis and error propagation, such that results from these experiments are confidently backed by statistical significance tests. I enjoy consolidating results into concise summaries with actionable recommendations, when applicable.
I am comfortable working on collaborative projects with version control, most commonly with Github. Most of my software development is in high level computing languages(MATLAB and Python), though I will occasionally use C++.
I enjoy designing and fabricating parts for custom systems. I most commonly use Autodesk Fusion 360 for designing 2D and 3D parts, which I then fabricate using a 3D Printer, Laser Cutter, or a CNC Router.
I am confident and have experience with many geospatial software packages. I used Agisoft Metashape extensively for my PhD research on Structure from Motion, though I have also used Pix4D. I commonly use CloudCompare for pointcloud visualization and interactive editing, and have traditionally avoided using Arc products in favor of writing custom MATLAB or Python scripts.
I have experience developing web pages, often building off of bootstrap templates and using libraries such as leaflet, potree, three.js, and more to visualize large geospatial datasets.

Interests
When I'm not working, I enjoy: surfing, rock climbing, mountain biking, kayaking, canyoneering, training for triathalons, golfing, camping, and really anything that gets me outside.
When the weather isn't cooperating, I don't mind staying inside and tapping into my creative side. I have a laser cutter, CNC router, and 3D printer in my living room and enjoy having friends over to build whatever we can think of.
