Forest Biometrician and Geospatial Data Scientist

I work at the intersection of measurement, data, and real-world decisions. Trained in forest biometrics, I build GIS, remote sensing, and statistical tools that make results useful, reproducible, and defensible.

What do we actually know, how well do we know it, and how can we turn that knowledge into something useful?

Forest Biometrics & Inventory Modeling

Forest inventory, growth & yield, forest mensuration, small area estimation, mixed-effects and machine-learning models on plot data, forest resources management

Your forest inventory tells you what a handful of plots look like. I build the statistical models — small area estimation, mixed-effects, machine learning — that turn those plots into reliable biomass and volume estimates for every county, stand, or parcel you manage. Forestry is where I started, and it still frames how I read every dataset.

Enterprise & Operational GIS

ArcGIS Pro / Online / Enterprise Portal, geodatabase and schema design, feature & REST services, spatial data management, GIS QA/QC

A forest inventory, a utility network, a research archive — none of it holds up without the GIS underneath. I design the geodatabase schemas, publish the feature and REST services, and set up the ArcGIS Enterprise Portal access and QA that let a whole team work from the same spatial data.

Remote Sensing & LiDAR

Satellite & LiDAR remote sensing, image interpretation, change detection, canopy & vegetation monitoring, land-cover classification

No field crew can walk every acre of canopy or every mile of utility corridor. I work with LiDAR and satellite imagery to detect, classify, and monitor change — vegetation structure, land cover, encroachment — at a scale field work can't match.

Geospatial Programming & Automation

Python, ArcPy, R, SQL, GDAL, custom toolboxes, automated geoprocessing, spatial databases

Spatial data scattered across shapefiles, LiDAR tiles, and field surveys doesn't help anyone decide anything. Whether it's a one-off geoprocessing script or a production toolbox, I build the Python and ArcPy pipelines, custom tools, and spatial databases that turn that mess into fast, repeatable analysis.

Spatial Data Science & Decision Support

Spatial statistics, machine learning, suitability analysis, interactive web mapping, map production, technical presentations

An estimate nobody can read is just a number. I turn spatial analysis into the maps, interactive applications, and briefings a decision-maker actually uses — from statistical models and suitability surfaces to web maps and field-ready reports.

Resume

Data Scientist with a foundation in forestry, forest biometrics, statistics, and geospatial analysis, with professional experience applying these disciplines in analyst roles. My work has brought together field observations, forest and vegetation data, remote sensing, LiDAR, spatial analysis, and statistical methods to understand real-world systems and solve practical problems. I am comfortable moving from an open question or imperfect dataset to a defensible analysis, whether that means investigating patterns, evaluating data quality and uncertainty, developing a spatial workflow, automating a process, or producing information that supports a decision. I bring the perspective of a scientist with the practical mindset of an analyst: understand the problem, examine the evidence, and build something useful from it.

Research experience

  1. Independent Researcher

    FIA Tree Height Codes: Crews vs. a Height Model — trained species × ecodivision height–diameter models on 11.8M field-measured FIA trees and used them to evaluate about 200,000 crew-reconstructed heights on broken-top trees; identified and diagnosed a spurious stump-height artifact by simulation, and mapped regional bias patterns across ecodivisions and states. Public write-up and reproducible code.

    Part 2: FIA's Own Height Model — checked FIA's undocumented HTCD 4 height model against the regional height–diameter model and against a remeasurement-based benchmark built from each tree's own measurement history; showed diameter-only models underestimate growth on larger trees and that FIA's close agreement with the benchmark likely reflects a shared input, not independent accuracy.

    Part 3: Carbon Density by Ecoregion — compared live-tree carbon density across 35 ecodivisions with design-based (post-stratified) estimates, Welch's ANOVA, Kruskal–Wallis, and Games–Howell/Dunn–Holm post-hoc tests; found a roughly 29-fold regional spread with high within-division variability, traced to FIA's sample design, and linked the highest-carbon divisions to heavier reliance on FIA-modeled heights. Built on PostgreSQL/PostGIS, SQLite, and Python.
