Materials scientist. My research covers ultrafast laser processing of metals and alloys: what it does to their microstructure, surfaces, and properties. PhD, University of Tennessee, Knoxville.
I build calculators and research software with cited, verified data, designed for people and for AI agents.

| Tool | What it does |
|---|---|
| Reference Electrode Potential Converter | Convert potentials between SHE, RHE, Ag/AgCl, SCE and other scales, with cited offsets |
| Thermocouple Converter | ITS-90 millivolts to temperature for all eight types, with cold-junction compensation |
| Diffusion Coefficient Calculator | Arrhenius diffusion with a literature-corroborated D0 and Q table |
| Alloy Composition Converter | Weight percent to atomic percent with IUPAC 2021 atomic weights |
| XRD Calculator | Scherrer crystallite size and Bragg d-spacing with anode wavelengths built in |
Every tool page carries its method, its data with sources, a worked example, and a reference list.
