Hello everyone, my name is Isaac. I’m joining this course from Texas, United States, although I’m originally from Nigeria. As a PhD student, I’m super excited to deepen my knowledge in Material Physics. My academic background includes a bachelor’s degree in physics with a minor in Education, followed by a master’s degree in Theoretical Physics. However, my passion has shifted towards Materials Physics, particularly focusing on renewable energy materials for Photovoltaic (PV) applications. I’m eager to leverage this course to enhance my expertise and become a proficient Materials Physicist, contributing meaningfully to the field of renewable energy. I look forward to learning from and interacting with all of you.
