Duane Loh

Research

Since his time at Cornell, Duane has been developing algorithms to probe nanoscale phenomena by examining their signatures, which are hidden in noisy, incomplete and heterogeneous X-ray diffractive datasets.

Structural complexity in aerosol soot: Scale-invariant random processes drive the growth and aggregation of these aerosols, which results in fractal-like geometrical properties.

These algorithms were applied during his postdoctoral appointment at SLAC National Accelerator Laboratory to investigate airborne aerosols, tiny viruses, paramagnetic aggregates, and supercooled water using X-ray free-electron lasers.

At NUS, Duane explores the physical, statistical and biological challenges encountered in electron microscopy and x-ray diffractive imaging to understand how we can extend our study and manipulation of mesoscale structure and dynamics.
