Welcome!
Welcome to the Pennathur Laboratory. We develop experimental and computational platforms to measure, model, and control coupled ionic transport phenomena in confined micro- and nanoscale systems. Our work integrates microfluidic device engineering, electrokinetic measurements, inverse modeling, and multi-physics simulation to enable new capabilities in sensing, actuation, and biomedical devices.
What We Do
Measure
We design microfluidic and electrochemical systems to measure ionic and molecular transport under confinement.
Examples: nanochannels, fluorescence, current measurements, PEDOT:PSS bipolar electrode sensing.
Infer
We develop inverse models to reconstruct hidden transport states from experimental data.
Examples: electrokinetic inverse modeling (EKI), pressure/flow reconstruction.
Control
We build electrostatic and electrokinetic devices that actively manipulate ionic flow.
Examples: zipper pump, microfluidic actuation systems, iontronic materials.
