Academic Tutor
- 2+ years of teaching experience
- Holds a Physics BSc and an MSc in Photonics Engineering, providing a strong academic foundation for IGCSE STEM subjects.
- Experienced in guiding interdisciplinary research teams and conducting specialized technical training sessions.
- Adept at translating complex scientific data into clear, accessible insights for students
Drawing from a deep background in experimental physics and biotechnology, I lean heavily on real-world applications and structural subject breakdown to make complex STEM topics relatable. I tailor my sessions to each student’s unique learning pace, ensuring they not only master the IGCSE curriculum but also build the critical thinking skills necessary for future academic success.
