2026 Mentors

Joseph P. Briggs
Post-Doc, Chemistry & Biochemistry
ORCID: 0000-0001-7892-4869
Joseph is a post-doctoral researcher in the UC San Diego Department of Chemistry and Biochemistry. He received his B.S. in Chemical Engineering from the University of Florida and his Ph.D. from Colorado School of Mines in Chemical and Biological Engineering, with a minor in Quantum Engineering, jointly advised by Carolyn Koh (CBE) and Reuben Collins (Physics). His PhD work focused on alternative forms of silicon for quantum information science.

Jiuk Byun
PhD Student, Materials Science & Engineering
ORCID: 0000-0001-9810-8869
Jiuk is a PhD student in Materials Science and Engineering at UC San Diego who joined the lab in 2023. She received her B.A. in Chemistry with a minor in Mathematics from Mount Holyoke College. She conducted her undergraduate research with Professor Wei Chen and helped develop a new procedure for spin coating polydopamine thin films. She also worked with Professor Dirk Englund’s group at the Massachusetts Institute of Technology, on nitrogen-vacancy centers in diamond. Before joining UCSD, she researched coatings and carbonization of nature-inspired polymer materials in Professor Haeshin Lee’s lab at the Korea Advanced Institute of Science and Technology. She participated in the Summer School for Silicon Nanotechnology remotely in 2021 and in-person in 2023, and served as a mentor in 2024. Her research interests include surface modification of porous silicon nanoparticles and materials for sensing and catalysis applications.

Ashley Tamura
MRSEC Associate Education Director
ORCID: 0000-0002-2540-6125
Ashley Tamura is the Associate Education Director of the UC San Diego MRSEC. She received both her B.S. and M.S. from UC San Diego while working on the phase-tunable colloidal synthesis of tungsten disulfide nanocrystals with Dr. Alina M. Schimpf. With her research background and her experience as an Adjunct Professor in the San Diego Community College and Southwestern College districts, Ashley forms a bridge between the research and the education elements of the MRSEC and the RIMSE program. She participated as an RET in the 2023 Summer School for Silicon Nanotechnology, and as a Senior Mentor in 2024. Her research focus is on the physical, chemical, and optical properties of porous silicon.
