Simulations and reconstructions that run live in your browser.
Much of my work involves solving inverse problems in electron microscopy: recovering the relevant information about a sample from different types of measurements. These demos let you play with the forward and inverse problems directly. Everything is computed live in your browser.
4D-STEM diffraction
Scan the probe across a polycrystalline sample and watch the diffraction pattern change for different probe convergence angles.
Multislice ptychography
Scan an electron probe over a nanoparticle, record a 4D-STEM dataset, and watch gradient descent reconstruct the sample slice by slice.
Lorentz TEM of skyrmions
Build a magnetic texture, see how it shifts the phase of the electron beam, image it out of focus, and reconstruct the magnetic induction with the transport-of-intensity equation.
