During one semester, I served as a laboratory peer tutor responsible for assisting in guiding students during practical sessions. The practical topics covered in the course included regulations, sample matrices, and the analysis of drugs, food, and cosmetics. I assisted with operating analytical instruments, preparing materials, and reviewing students' final reports.

During one semester, I served as a laboratory peer tutor responsible for assisting in guiding students during practical sessions. The practical topics covered in the course included dissolution studies, in vitro and in situ permeation, transdermal permeation, and pharmacokinetics using blood and urine data. I supervised the practical sessions, checked pre-test and post-test answers, and reviewed the students' final reports.

The internship was a collaboration between the university and the company. I was placed in the Quality Assurance division, specifically in calibration, qualification, and validation. However, I was also introduced to other divisions such as Quality Control and Production. In addition to learning the basics and tasks of Quality Assurance, I was assigned a special project to be completed within 2 months. I focused on the objectives, techniques, and cleaning validation methods during this project. I performed calculations for the RPN (Risk Priority Number) of drug products, MACO values using the MACOppm, therapeutic daily dose, and LD50 approach, as well as calculations for residue limits per sample area.
