WRITING

Notes and explainers on geospatial science, natural hazards, fieldwork, and the tools used to study changing landscapes.

FEATURED CASE STUDY

WHEN DEBRIS FLOWS LEAVE THEIR CHANNELS

My published master's research on debris-flow avulsion, physical modeling, 20-camera photogrammetry, 3D-printed channel geometries, and the role of bend geometry in runout behavior.

MARTIAN STRATIGRAPHY & THE INSIGHT LANDER

How orbital imagery, exposed stratigraphy, and GIS helped scientists think through the surface and subsurface conditions surrounding NASA's InSight landing region.

GEOGRAPHIC INFORMATION SYSTEMS

A plain-language introduction to GIS: what it is, how I use it in geohazards work, and how a beginner can start exploring spatial data with QGIS.

FROM PHOTOGRAPHS TO 3D MODELS

A practical look at photogrammetry, point clouds, meshes, and the process of turning overlapping images into measurable three-dimensional representations.

SCIENTIFIC WRITING

A guide to structuring technical ideas clearly - from the first research question through methods, results, interpretation, and revision.

Topics I plan to continue covering include terrain analysis, UAV mapping, LiDAR, post-wildfire hazards, GIS automation, field methods, and lessons from real geospatial workflows.
