ASC Oven Control

A desktop interface for the ASC thermal oven, with coordinated three-zone temperature control and run logging.

RapidPy

Software for paleomagnetic instrument control.

RepoHub

A lightweight desktop and menu-bar dashboard that tracks live progress across GitHub projects (milestones, issues, pull requests, CI and commits), sorted into editable research categories.

rotree

Visualize GPlates rotation hierarchies as cladograms, track reference-frame changes, and identify disconnected plates.

Mineral Habit Matrix

An interactive 3D atlas of 720 idealized crystal habits for 41 rock-forming, accessory and ore minerals, from Pupin's zircon typology to step-by-step construction from the lattice, with STL and STEP downloads.

Bonneville Shoreline 3D

An interactive 3D model of Lake Bonneville built on the Chen & Maloof (2017) dGPS shoreline dataset, with the isostatically deformed Bonneville shoreline, Sentinel-2 terrain, and an animated lake-level history from 30 ka to the present.

PmagPy

Contributing to open-source tools for paleomagnetic data analysis.

RockmagPy

Contributing to notebooks and workflows for rock-magnetic data analysis.

H2Matrices.jl

Hierarchical H²-matrix computations for numerical modeling.

DisconnectivityGraphs.jl

Tools for energy-landscape analysis using disconnectivity graphs.

TIMS 3D

Explodable, physics-based 3D models of thermal ionization mass spectrometers (Isotopx Phoenix, Nu TIMS, Thermo Triton XT), with traced ion optics, exploded resistor and capacitor amplifier workbenches, step-through Daly and SEM signal chains, Faraday noise, source tuning and total evaporation.

LA-ICP-MS 3D

Explodable 3D models of Thermo iCAP RQ and TQ ICP-MS coupled to 193 nm excimer and femtosecond laser-ablation systems, with quadrupole stability, collision/reaction-cell chemistry, crater growth and washout, and a U–Pb zircon spot workflow.

LA-ICP-ToF-MS 3D

An explodable Nu Vitesse time-of-flight mass spectrometer, with timed ion packets, reflectron energy focusing, argon blanking, MagneTOF signal formation and the laser-to-pixel acquisition clocks. Includes the accompanying LA-ICP-ToF-MS study notes.

Nu Sapphire 3D

Explodable 3D models of the Nu Sapphire dual-path MC-ICP-MS, with the collision cell, ESA and magnet double focusing, multicollection and mass bias, and independent low- and high-mass zones for static U–Pb collection.

Column Chem 3D

Step-by-step 3D illustrations of chemical abrasion and ion-exchange column chemistry, with simulated element bands for U–Pb anion columns, resin partitioning curves, and a protocol atlas across isotope systems.

Automated Rock Magnetometer 3D

Explorable 3D models of an automated superconducting rock magnetometer, with a 100-specimen X–Y stage or 200-specimen snake chain, orthogonal pickup coils and SQUID signal electronics.

VSM 3D

An explodable vibrating-sample magnetometer, with an electromagnet, vibrating sample rod, differential pickup coils, a voltage preamplifier and phase-sensitive lock-in detection.

SQUID Magnetometer 3D

Explore a superconducting magnetometer from its cryostat and axial gradiometer to the SQUID sensor, Josephson junctions and flux-locked-loop readout, with component zoom-ins and exploded views.

Sun Compass 3D

An animated, 3Blue1Brown-style 3D lesson on how a sun compass orients field samples, from hour angle and declination to the astronomical triangle, the shadow angle, and why the azimuth needs atan2 rather than arcsin.

Rock Magnetometry Lectures

Course notes and lecture materials on rock magnetometry.
