GIS & Remote Sensing Portfolio
Geoscientist (B.S., Drexel University) specializing in high-resolution terrain mapping: drone photogrammetry, terrestrial LiDAR and satellite remote sensing, from field data collection to finished, quality-checked GIS products. Co-author of a peer-reviewed Bulletin of Volcanology paper.
Each case study shows the real data, the workflow and its limitations.
Project 1 · Satellite remote sensing
Central Laos · ASTER, Sentinel-2, SRTM
A desk-based screening workflow that narrowed a ~10 km² property from 253 spectral anomalies to five ranked field targets, using ASTER alteration indices, terrain analysis and regional geology.

Project 2 · Terrestrial LiDAR
Anemone Geyser, Upper Geyser Basin · Velodyne LiDAR
Raw handheld Velodyne captures processed with SLAM into a 974,221-point cloud and a 0.18 m elevation model, with a written protocol so the workflow can be repeated.

Project 3 · Drone photogrammetry & field geochemistry
Nisyros, Greece · DJI drone, Agisoft Metashape, QGIS
Drone imagery from two field campaigns built into 5 cm orthomosaics and 10 cm DEMs, combined with 770 ground-temperature and 92 CO2 flux measurements. The 2022 work was used in a peer-reviewed paper.

Project 4 · Terrain modelling & volume analysis
San Francisco Volcanic Field, Arizona · SfM, ALOS PALSAR, QGIS
A drone-derived DEM of the SP Crater lava flow, used to measure a 0.29 km³ flow volume within 11% of the published estimate. Flows and vents were also mapped across the volcanic field as inputs to a probabilistic hazard assessment.
Read the case studyReconstruct
Processing drone imagery with Structure-from-Motion into orthomosaics, point clouds and DEMs.
Scan
SLAM processing of terrestrial LiDAR, point-cloud cleanup and gridding into elevation models.
Detect
Multispectral and radar imagery, band-ratio indices and terrain analysis for mapping and exploration targeting.
Check
Finding coordinate-system, datum and processing errors before they reach a map, and stating each map's real limits.

B.S. Geoscience, Drexel University, 2026
Academy of Natural Sciences & Vanderkluysen Lab, Drexel University
Generated DEMs and orthophotos from UAV Structure-from-Motion data. Computed lava flow volumes in GIS for 28 cinder cones to support a probabilistic hazard assessment. Sampled hydrothermal gas and ground temperatures with international teams on Nisyros, Greece. Taught and mentored remote sensing labs on LiDAR and SfM workflows.
Pennoni, Philadelphia
Operated ground-penetrating radar (GPR) as the primary field representative on multi-day site investigations, alongside borehole drilling and test pits. Performed 150+ infiltration tests to PA, NJ and Philadelphia standards, and digitized field logs.
Harvard University, Drabon Lab
Analyzed and visualized PM2.5 air-quality data in Python. Also used silicon and oxygen isotopes, rare earth elements and zircon trace elements to study magma evolution and crustal thickness.
Philadelphia Water Department
Calibrated and maintained YSI water-quality monitoring equipment at urban stream sites and collected data for watershed management.
