analysis, and multiphysics simulation. Actively engaged in DoD-funded research and thermal design of nuclear test
reactor capsules. Skilled in COMSOL Multiphysics, heat transfer, and parametric studies, seeking a Summer
Engineering Internship in nuclear R&D and thermal simulation.

Nuclear Test Reactor Capsule – Thermal & Radiation Heating Analysis (Ongoing)

• Developed and simulated the thermal response of a reactor test capsule subjected to gamma-ray energy deposition, generating temperature profiles that were utilized to assess capsule survivability and design margins.
• Created models of multi-layer capsule structures (core, can, gas gaps, and coolant interface) to pinpoint the primary heat-transfer pathways and peak temperature influences.
• Established 1D and 3D thermal resistance networks to corroborate COMSOL findings, enhancing confidence in numerical forecasts and enabling independent verification.
• Supported engineering trade studies by providing quantitative thermal comparisons and visualization plots to inform capsule design choices.

Skills applied: Nuclear heat transfer, radiation heating, COMSOL Multiphysics, thermal resistance modeling

CHAInMail – A Multiphysics and Thermal Modeling Initiative Funded by the Department of Defense (Ongoing)

• Participated in research funded by the Department of Defense that concentrated on energy deposition and modeling of transient thermal responses for systems relevant to defense.
• Created multiphysics simulation workflows that integrated time-dependent and experimentally obtained boundary conditions, allowing for an accurate replication of testing scenarios.
• Confirmed the simulation outcomes by comparing predicted temperatures with experimental data, highlighting trends of agreement and limitations within the model.
• Recorded simulation methods, assumptions, and findings in formal technical reports to comply with DoD reporting and review standards.

Skills Utilized: Multiphysics modeling, thermal validation, COMSOL
