Ideas worth staying with.

Before choosing a model, I want to know what it needs to help us decide. Which mutation should we test? Which pathway explanation can we rule out? Where should a sensor go? What should a controller do when the load changes?

Those questions look different, but they force the same discipline. What can we measure? What is hidden? Which assumptions are doing the work? And what would count as evidence that the answer is wrong?

Prediction is one part of the job. The rest is connecting that prediction to an experiment, an operating choice, or a piece of software that someone else can inspect and use. A model that cannot explain its intended use has not finished its work.

That is the thread my portfolio has pursued to date: to make visible scientific depth, engineering judgment, and the responsibility to keep uncertainty attached to the conclusion.

You do not need to choose between being curious and becoming technically strong. But curiosity becomes more useful when you give it a method.

Start with one system you can understand well enough to ask a specific question. Build a simple model. Check it against a measurement. Find out where it fails. Then explain that failure to someone else.

The domain may change later. The habit of asking clear questions, checking assumptions, writing usable code, and learning from evidence will travel with you.

My route from process-control work toward biological modeling is a testament to this, and very largely so. These are not identical systems. They are different places to apply a shared discipline of measurement, modeling, and careful decisions.
