GLAM Postdoctoral Fellows

2020-2022

Aristide Gumyusenge

Aristide Gumyusenge received his Ph.D in Chemistry from Purdue University in 2019 after his research on polymer-based high temperature organic electronics in the research group of Prof. Jianguo Mei. He joined Stanford in January 2020 as the Geballe Laboratory for Advanced Materials (GLAM) Postdoctoral Research Fellow. His research will focus on organic-based artificial synapses for neuromorphic computing. Aristide likes to play (and watch) soccer and basketball.

Maja Bachmann

Maja Bachmann is an enthusiastic experimental physicist broadly interested in the field of quantum materials. During her PhD, she has specialized in the burgeoning field of focused ion beam (FIB) microstructuring of single crystals. The precise tailoring of the shape and size of crystalline devices allows her to investigate phenomena that cannot be studied in bulk samples. At Stanford, Maja is excited to combine her FIB expertise with uniaxial strain tuning – a powerful technique to control quantum matter pioneered in Prof. Ian Fisher’s research group. In particular, she is interested in probing and controlling the emergence of charge density wave (CDW) order and the dynamics of the CDW state for quasi-2D systems.

Ting Cao

Ting Cao’s research employs high-performance computing, advanced materials modelling techniques, and quantum physics to study topics in condensed matter physics and materials science, with special focus on the electronic structures of materials, excited-state phenomena, and light-matter interactions. Ting Cao’s current research interest lies in exploring the distinct physical properties of one- and two-dimensional material systems potentially useful for future applications.

Ruijuan Xu

Ruijuan’s research interests focus on the design and synthesis of novel oxide thin films and artificial nano-architectures using advanced thin-film epitaxy and nanofabrication. She uses multi-scale thin film characterizations to exploit and control emergent properties in these materials at the nanoscale.

Siying Peng

Siying's interests include mid-infrared nanophotonics, topological photonics and 3D photonic materials. Her research at Stanford focuses on mid-infrared light emission and absorption of GeSn nanowires. She also explores unique plasmonic and phononic properties of gold nanoparticles with hcp crystal lattices.

Edbert Sie

Edbert Sie received his PhD in Physics at MIT, supervised by Prof. Nuh Gedik. Sie is interested in searching for novel quantum phases of matter at nonequilibrium, with particular interests in 2D condensed matter systems. At Stanford and SLAC, he uses intense electromagnetic radiation in the THz frequency to induce structural changes in these materials and take snapshots of the atomic-scale structure in motion using relativistic ultrafast electron diffraction. In combination with various ultrafast laser techniques, his research aims to innovate new ways of manipulating quantum materials at the atomic scale and on the femtosecond timescale, enabling future electronics and energy storage technologies.

2016-2018

Matthew Gebbie

Matthew’s research focuses on developing techniques and materials to understand and engineer the molecular properties of electrochemical and biological interfaces. As a GLAM Fellow, his projects center on tackling fundamental questions surrounding the synthesis of diamond nanomaterials and designing new approaches for creating crystallographic color center defects in diamond lattices for fluorescent bio-imaging and electric field sensing.

Sean Hart

Hart’s research focuses on the electronic properties of materials in reduced dimensions, particularly when placed in proximity to conventional superconductors. Currently he is interested in the properties of Josephson junctions based on InAs nanowires, a candidate quantum information processing platform.

Yang Liu

My research focuses on the atomic manipulation using scanning tunneling microscopy technique. We reveal a gentle charge fluctuation on Cu surface using a scanning quantum cantilever formed by mounting one CO molecule on the STM tip. In the strained artificial graphene, I demonstrate that the magnetic flux quanta enclosed by the Landau level wavefunctions persists remains constant even when the length-scale of the magnetic confinement is comparable to the lattice constant.

Laura Marquadt

Despite numerous clinical trial attempts, the use of cell-based therapies for treating spinal cord injury have yet to translate into an effective clinical treatment due to poor cell survival and function. Dr. Marquardt's research sought to design an injectable hydrogel platform to overcome these translational limitations. Through recombinant protein engineering and biomaterial design approaches, Dr. Marquardt investigated a material called SHIELD that promotes enhanced transplanted cell retention and function resulting in improved functional recovery after spinal cord injury.
