Research

I got into a research lab in my first semester of undergrad as a volunteer. Not for credit, not because it was required. I just wanted to be there. I came to biomedical engineering already knowing I wanted to work on the engineering side of healthcare: building better tools for detection and measurement, not treating patients directly. The lab was where that started to become real.

The through-line from biosensors and BioMEMS to cardiac modeling is less of a pivot than it looks. It is all the same question: how do you measure what the body is doing, as precisely and non-invasively as possible? Microfluidic point-of-care devices, graphene electrodes for environmental biosensing, Bayesian reconstruction of cardiac conduction from an ECG: different scales, different tools, the same engineering problem.

I think of myself as an engineer who does research, not a researcher who uses engineering tools. The instinct is always to ask what can be measured, reproduced, and verified. That question is what connects the bench work, the publications, and the thesis.

M.Sc. in Data Science, Pontificia Universidad Católica de Chile
