The Ultrafast Electron Imaging LabThe Sciaini Group

Watching matter in motion

We build tools to see how atoms move, how electrons respond, and how structure gives rise to function.

02 / RESEARCH

We answer fundamental questions at small scales

Our in-house instruments connect ultrafast spectroscopy, electron diffraction and microscopy to reveal the dynamics hidden within matter.

01 — STRUCTURAL DYNAMICS

Capturing atoms in motion

Compact ultrafast electron diffraction reveals how crystal structures evolve after light excitation. We develop electron sources and examine the practical limits of temporal resolution and scattering sensitivity.

02 — QUANTUM MATERIALS

Following electronic energy

Femtosecond optical probes track excitons, defects and collective states in two-dimensional materials. Complementary structural measurements disentangle the responses of electrons and the lattice.

03 — LIQUID-PHASE MICROSCOPY

Seeing life at the nanoscale

Engineered nanocontainers and air-free sample loading enable reproducible thin liquid layers, bringing nanomaterials and delicate biospecimens into view in their liquid environment.

    05 / PRINCIPAL INVESTIGATOR

    Germán Sciaini

    Professor of Chemistry
    University of Waterloo

    Germán Sciaini leads the Ultrafast Electron Imaging Laboratory, where custom instrumentation opens new ways to investigate molecular structure and dynamics—from quantum materials to soft matter and biological specimens.

    He received his Ph.D. in Physical Chemistry from the University of Buenos Aires in 2006. After postdoctoral and research appointments at the University of Toronto and a group leadership position at the Max Planck Research Department for the Structure and Dynamics of Matter in Hamburg, he joined Waterloo in 2014. He became Professor in 2025.
