📚 My Research
My research bridges electrical engineering, civil engineering, and materials science, developing rapid electrical (ohmic) curing and additive manufacturing of fly-ash–based geopolymers and characterizing the electrical conductivity and resistivity of sustainable construction materials.
The unifying goal is to turn industrial by-products such as fly ash into lower-carbon construction materials, and to use electrical methods to cure, monitor, and 3D-print them faster and more reliably.
I am seeking research-focused roles in academia, national laboratories, and industry R&D, and welcome opportunities to collaborate.
