Projects · Research · Frameworks · Media

The work is not a collectionof disconnected final outcomes.

This timeline preserves launches, revisions, publications, experiments, presentations, and changes in understanding.

Why preserve history?

A current system hides the assumptions, mistakes, and revisions that produced it.

The timeline keeps those transitions visible. It shows that frameworks were revised, ranking assumptions were removed, prototypes failed, and questions changed.

Context-dependent signal research

Began formalizing how domain and learning context alter the meaning of behavioral traces.

In Progress

Contextual Interpretation of Behavioral Signals

This developing paper investigates the contextual dependence of behavioral evidence. It begins by distinguishing behavior from behavioral traces, then examines how domain, knowledge state, learning objective, content type, interface, emotion, and time can alter interpretation. The initial paper focuses primarily on domain.

The Illusion of Learning

This research and communication project examines learning as a latent process. It asks what observable evidence can support the claim that capability changed and distinguishes feelings associated with learning from demonstrations of recall, performance, transfer, teaching, creation, and reflection.

Project

GlobalBriz v0.2

Completed a major redesign and connected community, housing, answers, and moderation systems.

The Illusion of Learning

Attention, familiarity, completion, and fluency can feel like learning without necessarily demonstrating that capability changed.

Media
Short Series

Evidence of Learning

A short-form series asking what evidence supports the claim that learning actually occurred.

Framework
Current

Sufficient Understanding Framework v1.0

Established the seven-stage framework for deciding when understanding is sufficient for action.

Project
GlobalBriz

Initial information architecture

Defined community, housing, guides, resources, jobs, and support modules.

Personal Philosophy

Building Systems Under Uncertainty

The systems I care about most are the ones where outcomes are uncertain, signals are noisy, and decisions still need to be made.

Framework
Current

Evidence of Learning v1.1

Expanded the framework to include Recall and Reflection.

Project
EPA Air-Quality Exploration

Research reflection

Documented the research process and methodological lessons.

Research
Completed

Monitor Only vs. Monitor and Model

This project used EPA air-quality data to examine the distinction between observing environmental conditions and constructing a model intended to explain or predict them. It emphasizes that visual patterns and measurements do not independently establish causal relationships.

Project
TechXEng

Parametric design progress

Moved from underdefined sketches toward fully defined links and design intent.

Project
EPA Air-Quality Exploration

Research presentation

Presented the distinction between Monitor Only and Monitor and Model.

The App Started Building Me

I thought I was building a software product. Somewhere between the bugs, failed assumptions, and rewritten systems, the product began changing the builder.

Project
Human-Like Robotic Hand

First 3D link

Moved the design from a two-dimensional sketch into a three-dimensional component.

Project

GlobalBriz exploration began

Started exploring a unified immigrant-support platform.

Project
Human-Like Robotic Hand

SolidWorks fundamentals

Developed the first fully defined parametric finger-link sketch.

Project
Hydrogen Turbine Research

Energy-flow model

Connected combustion behavior to turbine work and compressor operation.

Research
Exploratory

Hydrogen Combustion in a Small Turbine System

This engineering research exploration examines hydrogen combustion in a turbocharger-based or small gas-turbine system. It considers mixing, combustion zones, temperature, turbine work, materials, and safety as connected parts of one system.
