Cj Isaiah Ferrer

Applied Physics major in Instrumentation graduate with clinical medical physics training focused on the safe and accurate use of radiation-related equipment. Completed 200 hours of structured training at University of Santo Tomas-Hospital (UST-H), including 120 hours in Radiation Therapy, participating under medical physicist in LINAC QA/QC, radiation dose measurement, and radiation safety procedures. Complemented by undergraduate research in radiation physics involving Phyton-based computational modeling and quantitative analysis.

Seeking to apply this foundation to radiation protection, equipment safety, and compliance-focused operations.
