This is where the habit started: a valid setup still has to work outside the lab.

Seismocardiography (SCG) records the small chest-wall vibrations associated with the heart’s mechanical activity.

I helped design experimental protocols, conducted human-subject testing, developed physiological signal-acquisition software, worked with instrumentation, and helped make the setup substantially more portable.

The work kept returning to the bridge between experimental validity and practical usability: a technically valid system still has to be usable outside the lab.
