The Optical Science and Nonproliferation (OSN) Group is proud to announce that doctoral students Weslee Kersey and Hannah Patz have successfully passed their PhD candidacy exams. Both are enrolled in the Nuclear Engineering Sciences program, where they have demonstrated innovative research and a dedication to advancing the field.

Kersey’s dissertation proposal, “Investigation of Plasma Chemistry and Shock Wave Dynamics in Laser Ablation Surrogate Detonation Studies,” explores how laser-induced plasmas can help simulate nuclear detonation phenomena. By analyzing crater formation, plasma behavior, and shock wave expansion, her work may ultimately refine forensic techniques used to identify materials following a nuclear event.

Patz’s research, titled “Digital Autoradiography for Nuclear Forensics via iQID,” focuses on developing a novel, real-time detection system for alpha and beta particles within complex samples. Her project seeks to streamline and enhance post-detonation analysis by enabling faster, more accurate mapping of radioactive debris in diverse materials.

Both students will continue their research under faculty, national laboratory, and DoD guidance, with plans to present their findings at academic conferences and in peer-reviewed publications over the next three years. Their progress underscores the group’s commitment to preparing highly skilled researchers who push the boundaries of nuclear science and engineering in support of U.S. national security.

Congratulations to Weslee and Hannah on this significant milestone!
