- Postdoctoral Research Fellow, Electrical and Computer Engineering
- Ph.D., Electrical and Computer Engineering
- M.S., Electrical and Computer Engineering
Biography
Sebastian Celis Sierra received the B.Eng. degrees in Electrical and Electronics Engineering from Universidad de los Andes, Bogotá, in 2018, and the M.S. and Ph.D. degrees in Electrical and Computer Engineering from King Abdullah University of Science and Technology (KAUST), Thuwal, Saudi Arabia, in 2020 and 2026, respectively. He is currently a Postdoctoral Fellow at KAUST under the supervision of Hakan Bagci. His research interests include computational electromagnetics, specifically time-domain integral equation solvers, bianisotropic structures, and the characterization of 2D materials like graphene.
Research Interests
Sebastian's research focuses on formulating and implementing surface and volume integral-equation methods in both the time and frequency domains to capture complex electromagnetic behavior in arbitrarily shaped metasurfaces. By coupling these formulations with generalized sheet transition conditions (GSTCs), he aims to achieve both numerical efficiency and physical fidelity. His work advances the theoretical foundations and practical computational tools necessary for the next generation of communication systems.
