Construction materials account for more than 10% of CO2 global emissions, highlighting the surging need for low-carbon building materials. Introducing carbon-sequestrating fillers in building materials with low-emission processes increases the possibility of decreasing the environmental impact of building materials. Deconvoluting the effects of chemical compositions of fillers and microstructure on the mechanical performance, insulation properties, and carbon sequestration ability of composites is crucial to the application. My research focuses on developing manufacturing methods using carbon-storing biobased materials to improve the mechanical properties and energy efficiency of green construction materials.

Department: Materials Science & Engineering Faculty Advisor: Eleftheria Roumeli I am a third year PhD student in Materials Science and Engineering at the University of Washington. I work with professor Eleftheria Roumeli in developing novel bio-based polymeric materials that are both lower in life-cycle emission than traditional polymers and are biodegradable from fully-renewable biomass feedstocks. My research aims to understand the interactions and bonding between different constituents of biopolymer and biocomposite systems and to unlock the underlying correlations between raw materials, processing conditions and the properties of the final product....

Department: Chemistry Faculty Advisor: Brandi Cossairt Precise synthesis of quantum dots, rods, and wires with tunable light emission enables energy efficient optoelectronic technologies, and indium phosphide (InP) is a promising replacement for highly toxic cadmium- or lead-containing semiconductors. My research as a fourth year graduate student in the Cossairt Lab focuses on mechanistic understanding of InP nanocrystal synthesis with less toxic precursors and lower energy input. I am investigating my recent discovery of a new synthesis for InP nanorods requiring lower energy input and fewer precursors than existing syntheses. I aim to establish design rules to grow nanorods with diameters around 5 and 500 nanometers to...

Department: Physics Faculty Advisor: Juin-Haw Chu Magnetism and ordered phases in quantum materials have many applications, from energy-efficient data storage to superconductors that can transport electricity perfectly with no losses. In my work as a PhD student under Dr. Jiun-Haw Chu, I synthesize and study single crystals of quantum materials in order to figure how what makes their electronic and magnetic properties tick. In particular, my research focuses on strain as an axis of control- by manually altering the symmetry of a crystal, we can induce changes in the magnetic ordering, manipulate the population of spin domains, and investigate underlying behavior that couples to strain, such...
Grant Dixon
Department: Chemistry Faculty Advisor: Brandi Cossairt My name is Grant Dixon and I am a third year chemistry graduate student working in the lab of Dr. Brandi Cossairt. My research utilizes synthetic chemistry to study the photophysical behavior of colloidal nanocrystals as a function of chemical transformations on surfaces and across interfaces. Colloidal nanocrystals are of interest for next-generation, high-efficiency lighting technologies due to their size-dependent and surface-sensitive optical properties. Realizing these technologies at scale requires precise, deterministic synthetic developments that afford desired photophysical outcomes, which are historically lacking. I am approaching this problem through the synthesis of atomically-precise nanocrystal molecules with rigid ligand networks to resolve the influence of ligand dynamics and diffusion...

My research is broadly focused on synthetic methods of introducing porosity to semiconducting or magnetically ordered materials. More specifically I focus on the incorporation of silsesquioxane 'pillars' between layers of two-dimensional perovskites. Introducing porosity into perovskites increases surface area for applications in energy storage and catalysis and allows for post-synthetic modification through intercalation of small molecules.

I will use computational and theoretical approaches to understand and predict topological effects of materials in their optically excited states. Currently, I am wrapping-up an investigation on a novel interband index T for 2D systems (such as transition metal dichalcogenides). We showed that T may provide gauge-invariant excitonic optical selection rules and help characterize valley topology in excited states. Next, I will develop robust DFT-based computational schemes to calculate T in other materials beyond tight-binding frameworks. I will simultaneously study T in non-Hermitian systems; which are realistic quantum systems with gain and loss due to interactions with optical fields and environments. I am interested...
