I spent six years making tiny silicon membranes tell us — this is the story.

A MEMS engineer turned computational creativity researcher. Doctoral work at ESIEE Paris (ESYCOM Lab, 2010–2014) under Dan E. Angelescu produced a dual-axis optofluidic inclinometer reaching 0.0073° on under 1 mW — patent via SATT, six papers across IEEE MEMS, PRL, RSC Advances, Lab on a Chip. Since 2025, building Concept Collider at Emergence Lab : a white-box framework for fertile creative emergence. Accepted at ICCC 2026 (Coimbra, 29 June – 3 July).

I spent six years making tiny silicon membranes
tell us which way is up.
— this is the story.

The physics underneath is what kept me going — a steel ball rolling on a membrane, light bending through a liquid, a tilt angle encoded in a photocurrent. My work sits at the intersection of microfluidics, photonics, and precision sensing, where the most interesting questions live in the gap between disciplines.

7 papers, one ongoing conversation.

Each entry carries a synopsis and an aside — what the paper means, what I'd say about it in person.

N° 01

Dual-axis sub-0.05° optofluidic inclinometer

IEEE MEMS
~2013 · first author · ↓ PDF

Figure for Dual-axis sub-0.05° optofluidic inclinometer

Deflected silicon membrane + steel ball / mercury droplet + quadrant photodetector. Sub-0.05° linear range on ±1°. Under 1 mW total power. Built for civil-engineering structural monitoring (bridges, highway panels).

if you only read one of these, read this one. It's where everything started.

N° 02

Mechanism of microfluidic bubble production by foam emulsification

Physical Review Letters
2012 · second author · ↓ PDF

Figure for Mechanism of microfluidic bubble production by foam emulsification

Semi-empirical model for monodisperse bubble generation in microchannel emulsification. Pinch-off asymmetry, capillary number scaling, prediction validated across four geometries.

my first PRL — still a slight disbelief about it.

N° 03

Submicron nanodrops by gas-to-liquid phase transition

RSC Advances
2013 · third author · ↓ PDF

Figure for Submicron nanodrops by gas-to-liquid phase transition

CO₂ + perfluorohexane bubbles shrink under controlled diffusion and condense into submicron droplets. Radius scales as γ^(1/3) over three orders of magnitude. A scalable route to nanoemulsions.

γ^(1/3) over 1000× — the most elegant scaling law I've ever worked with.

N° 04

Optofluidic inclinometer — ESYCOM poster

ESYCOM 2013
2013 · first author · ↓ PDF

Figure for Optofluidic inclinometer — ESYCOM poster

Compact poster format of the IEEE paper. σ_y = 0.033°, σ_x = 0.063° (steel ball). σ_y = 0.024°, σ_x = 0.051° (mercury droplet).

my first poster. I clearly have a thing for posters — this entire page is one.

N° 05

High-precision optofluidic inclinometer on nano-patterned superhydrophobic surface

Lab on a Chip
~2016 · first author · ↓ DOCX

Figure for High-precision optofluidic inclinometer on nano-patterned superhydrophobic surface

Black-silicon DRIE-cryogenic etching + 100 nm C₄F₈ fluoropolymer coating → contact angle → 180°. Hysteresis nearly suppressed. Best configuration (NS-L-2, mercury, BSi): σ_x = 0.0073°, σ_y = 0.0126°.

the one that taught me what patience really means.

N° 06

Low-power optofluidic microsystems — intermediate thesis manuscript

Université Paris-Est · ESIEE Paris
~2014 · author · ↓ PDF

Figure for Low-power optofluidic microsystems — intermediate thesis manuscript

State of the art and design space of MEMS inclinometers. Force-balance, piezoresistive, capacitive, electrolytic, thermal, ferrofluidic. No prior system satisfies precision + low power + bi-axial + low-cost simultaneously. Directed by Dan E. Angelescu.

also the most-read thing I've written — ironically because of its bibliography.

N° 07

The Concept Collider: A White-Box Computational Framework for Targeted Creative Emergence

ICCC'26 — Coimbra, Portugal
2026 · first author · publisher ↗

Figure for The Concept Collider: A White-Box Computational Framework for Targeted Creative Emergence

A computational framework modelling creative emergence as precision-targeted collisions between concepts from decorrelated domains. 44 collisions, 100% emergence rate at mean score 8.24/10. First white-box computational creativity system — every emergent concept fully traceable to its source, fracture operator, and collision step.

A paper tells you the result.
It rarely tells you the road.

A few questions I'd want you to ask me, if we were sharing a coffee. The answers are mine — please read them as such.

Don't read me — talk to me.

All six papers above live inside my ScholarRAG. Ask any question — the methodology of the bubble paper, why mercury beat the steel ball, what I'd do differently with what I know now. The answer comes back with the page number, and it's grounded in what's actually written.

It's me, in conversation form. Twenty-four hours a day. Never tired.

What if your research collided with a distant domain?

The Research Collider shoots a semantically distant domain at this corpus and extracts a traceable emergent direction — white-box, every step auditable: corpus anchor, fracture type, S-factor, emergent hypothesis.

This page is what a ScholarRAG looks like —
and it is the first of its kind.

I'm Sebastian Wahl, and I'm building ScholarRAG — a platform where any researcher, independent or academic, can have a page like this : own corpus, own AI, own continuity.

Your ScholarRAG follows you across institutions. The lab page disappears when you change posts. This one doesn't.
