Chemistry - Inorganic/Materials Chemistry Seminars

This talk will focus on my past and present research initiatives, as well as how they relate to my future research program expanding the capabilities of additive manufacturing (AM) processes by increasing their material scope and chemical complexity. In addition, I will discuss my goal to couple multimaterial AM methods with in-situ characterization and closed-loop feedback to speed up and automate materials optimization and discovery toward target applications. I am currently developing a prototype of this automated platform at Lawrence Livermore National Laboratory (LLNL) targeting increased ionic conductivity polymer electrolytes for lithium-ion batteries. Ultimately, vertical integration and control over the molecular, microscale, and macroscale interactions can be leveraged to create novel AM processes as well as smart, adaptive multi-responsive objects with controlled responses to target stimuli. One highlighted example from my work is the invention of a novel multi-wavelength vat photopolymerization method called Multimaterial Actinic Spatial Control (MASC) AM. Using orthogonal photopolymerization systems initiated via different wavelengths of light, chemical compositions and mechanical properties can be dictated spatially in printed multimaterial objects through simple multicolor irradiation. The end of this talk will provide insight into my teaching philosophy, as well as how I envision my research fitting in within the department.
