Research

Applied mathematics for complex flow and transport.

My research interests lie in applied mathematics, fluid dynamics, and mathematical modeling, with applications to microfluidics, biological fluid mechanics, and deformable cells. My work combines asymptotic analysis, computational modeling, and scientific computing to study complex fluid-structure interactions and transport phenomena.

Research areas

Inertial migration in microfluidic devices

I developed a hybrid numerical and asymptotic model for inertial migration of a sphere in a rectangular channel. The resulting model showed strong agreement with experimental observations and informed a model of pairwise dynamics in microfluidic crystals.

Flow past hairy surfaces

To understand how marine crustaceans use their hairy appendages for sensing and feeding, I modeled the flow past hairy surfaces.

Modeling deformable cells

I am developing a reduced-order model for the family of constant-volume shapes a mammalian cell can take in microfluidic devices, using spherical harmonics to represent cell shapes.

Edge detection techniques applied to cell data to determine cell shape
Brijesh Patel applied edge detection techniques to experimental and numerical cell data.

Open-source research code

Matlab code for the inertial lift force on a particle in rectangular channels with aspect ratios AR = 1, 2, 4, 8, and 9 is available on GitHub.

Mathematica code for computing Lamb's solution external to a sphere is also available on GitHub.

HoodFlowLab on GitHub hosts the most recent code for modeling deformable cells using spherical harmonics.
