R&D Projects

Computational fluid dynamics and biomedical research — patient-specific simulation, surgical training systems, and beyond.

Project 01

Simulation-Based Prediction of Sleep Apnea

Patient-specific CFD/FSI methodology — from MRI acquisition to airway-collapse prediction — that became the basis of U.S. Patent 12,211,209.

Fig 1 — MRI scan depicting the upper airway of a patient with severe OSA.

The critical first step is MRI image acquisition — high-resolution cross-sectional imaging of the patient's upper airway (nasal passages, pharynx, soft palate, tongue). MRI is advantageous for superior soft-tissue contrast. Following acquisition, segmentation in MIMICS or 3D Slicer generates a continuous 3D surface model exported as STL/IGS — the computational domain for CFD.

CFD Governing Equations & Solution Setup

Turbulence Model Selection

ModelDescriptionRecommendation
LaminarSmooth, orderly flow — low resting breathing rates only.Not recommended for OSA.
k-ω SSTRobust RANS model — excellent for flow separation and near-wall effects.Best practice for steady-state OSA simulations.
Standard k-εLess accurate near walls.Less accurate than k-ω SST for upper airway.
LESMost accurate for unsteady turbulent flow — massive compute required.Reserved for advanced transient analysis.

Key Results

  • Minimum wall pressure (Pmin): Highly negative values indicate collapse risk.
  • Flow resistance R = ΔP/Q: Direct measure of airway obstruction.
  • Velocity jets: High-velocity jets downstream of the narrowest segment pinpoint collapse location.
  • Turbulent Kinetic Energy (TKE): Site of obstruction and source of snoring.

Microfluidics & PoC

Engineering the future of point-of-care health — portable, rapid, user-friendly devices that deliver results at the patient's side.

— The Discipline

Why microfluidics is hard.

Shrinking a laboratory onto a chip the size of a credit card changes the physics. At sub-millimetre scale inertia all but disappears, surfaces dominate over volumes, and fluids that would turbulently mix in a beaker instead glide past one another in perfectly ordered layers. Designing reliable diagnostic cartridges in this regime means working with that physics, not against it.

Over the past decade I've designed, simulated, and validated microfluidic systems for infectious-disease assays, point-of-care diagnostics, and biosensors — moving fluid without pumps, mixing reagents without turbulence, and metering nanolitre volumes repeatably enough to pass clinical verification. Three dimensionless numbers quietly govern almost every design decision in this work.

Re

Reynolds number ≪ 1

Inertia is negligible, so flow is laminar and reversible. Mixing can't rely on turbulence — it has to be engineered through geometry, diffusion length, or chaotic advection.

Pe

Péclet number

Sets the race between convection and molecular diffusion. It dictates how long a channel must be — and how serpentine — for two reagents to fully combine.

Ca

Capillary number

Balances viscous drag against surface tension. It governs droplet pinch-off, passive capillary filling, and whether a channel wets cleanly or traps air.

In practice this means a microfluidic cartridge is never "just a part." Channel cross-sections, wall roughness, surface energy, and material selection are all co-designed with the assay chemistry, then verified against CFD before a single mold tool is cut. The sections below walk through that workflow — from the markets these devices serve, to the governing flow physics, to manufacturable concepts.

Introduction

A decade turning hard physics into devices that serve people.

I'm a Senior Mechanical Design Engineer and doctoral researcher with more than ten years spent taking biomedical and microfluidic products from first principles to compliant, high-volume manufacture. My work lives at the intersection of fluid dynamics, mechanical design, and regulated product development — where a simulation has to survive contact with a real patient, a real production line, and a real audit trail.

My PhD built patient-specific CFD and fluid-structure-interaction models of the human upper airway that became the basis of a granted U.S. patent for predicting and treating obstructive sleep apnea. I've since carried that same rigor into industry — designing microfluidic cartridges, point-of-care diagnostic instruments, and single-use medical devices under ISO 13485, translating CFD, FEA, and FMEA into hardware that ships.

I care about the unglamorous details that decide whether a device actually works in the field: tolerance stacks, mold-flow behavior, design-for-manufacture, and verification and validation. Good engineering tends to be invisible — you only notice it when it's missing.
