How I Build
A consistent process for moving from an open problem to working, tested hardware.
Build
Define
Understand the biological, technical, or clinical problem.
Design
Develop system architecture, electronics, and mechanical components.
Build
Prototype circuits, firmware, PCBs, and physical systems.
Test
Characterize signals, hardware behavior, and system performance.
Iterate
Refine the system using experimental results.

How I Research
A structured process for turning scientific questions into measurable experiments, interpretable data, and engineering insight.
Research
Question
What do we need to understand?
Identify the biological phenomenon, engineering limitation, or unanswered question worth investigating.
Literature
What is already known?
Review existing methods, prior work, and open gaps to see where a better approach is possible.
Hypothesis
What should happen?
Define measurable variables, expected behavior, and criteria for evaluating the idea.
Experiment
How can we measure it?
Design the instrumentation, protocol, and data-acquisition approach needed to test the idea.
Analysis
What does the evidence show?
Process signals and results, quantify performance, and determine whether the data supports the hypothesis.
Refine
What should we test next?
Use the results to improve the experiment and shape the next question.
