Postdoctoral Scholars

Matthew Landsman

Matt is a postdoctoral fellow at the Advanced Light Source in collaboration with the Center for Materials for Water and Energy Systems (M-WET) at the University of Texas at Austin. Matt received his B.S. and M.S. degrees in civil and environmental engineering from the University of Maryland in 2016 and 2017, respectively, and his Ph.D. in civil and environmental engineering from UT Austin in 2022. His dissertation studied polymer membranes for water purification with a focus on boron removal and membrane fouling by natural organic matter. At the ALS, Matt employs X-ray spectroscopy and scattering techniques to study water treatment materials. Outside of research, Matt enjoys running and biking, learning new things, and spending time outside with his dog.

Jonathan Chan

Jonathan is a postdoctoral researcher at the Advanced Light Source. He received his BS in Chemical Engineering from the University of California San Diego in 2017 and his PhD in Chemical Engineering from Northwestern University in 2023. His thesis work investigated single chain physics within bulk polymeric material by direct imaging using super-resolution microscopy. Jonathan’s work at the ALS focuses on ion-conductive membranes and inorganic/organic nanocomposites. Outside of research, Jonathan enjoys going to concerts, watching movies, and finding new places to eat.

Supriya Gupta


Supriya is a postdoctoral fellow in the Materials Sciences Division and the Advanced Light Source. She obtained her MTech in Chemical Engineering from IIT Roorkee followed by a PhD in Chemical Engineering from IIT Delhi in India. Her doctoral research investigated the self-assembly of block copolymers with complex architectures using mean-field calculations. Supriya performed experimental studies on block copolymers at the University of Minnesota as a postdoctoral fellow. Supriya’s work at LBNL focuses on studies related to polymer nanocomposites using advanced X-ray scattering techniques. Outside research, Supriya enjoys being in nature, particularly in the mountains, and exploring new places.

Graduate Students

Olivia Gough

Olivia is an ALS Doctoral Fellow whilst completing her PhD in Condensed Matter Physics from the University of Oxford. She received her MRes degree in Plastic Electronics from Imperial College London in 2021, and her BSc in Physics from Queen Mary University of London in 2020. Olivia’s work focuses on characterizing the microstructure of vacuum thermally evaporated organic thin films using a suite of X-ray techniques. She is particularly interested in small molecules used for photovoltaic devices and developing in situ techniques to understand best processing conditions. In her spare time, Olivia loves music and being in the mountains!
