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.

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.

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.

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.

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.

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.

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.

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.
