Research

Asking how the world works — and who it works for

Two chapters of research, a decade apart: the physics of light and matter at the nanoscale, and now the very human question of how technology can serve people as they age.

Physics & nanotechnology

I earned a PhD in nanophysics (CEA Grenoble) and an MSc in nanotechnology (KTH, Stockholm), then spent years at Harvard as a postdoctoral researcher and lecturer in electrical engineering — part of more than a decade in physics. My work centered on germanium nanowire light sensors, nanophotonics, and nanofabrication — and I taught coursework in MEMS and nanofabrication.

The Digital Hearth

At Harvard’s School of Engineering and Applied Sciences, I research the intersection of aging and artificial intelligence through a project we call The Digital Hearth. Technology moves fast, but older adults are rarely included in how it’s designed.

We partner with local community organizations to host dialogues that demystify AI for seniors and caregivers. By listening to their lived experiences, hopes, and fears, we’re developing ethical design frameworks so that future assistive technologies prioritize human connection, agency, and trust over mere functionality.

Both chapters come down to the same habit: careful method, pointed at something human. Whether it’s a light sensor or a conversation with an elder about a chatbot, I care about getting it right — and about who it’s for.
