**Lecture videos**

- I have contributed and will contribute to METU OpenCourseWare project. You may find some video lectures of mine at the official YouTube channel of this project.
- I also recorded some of my lectures, as a part of online lectures that are held during the COVID-19 crisis in 2020. You can reach the YouTube playlists of MATH 119 (Spring 2020) from this link and MATH406 (Spring 2020) from this link.
- During Fall 2020, Spring 2021 and Fall 2021, I also recorded videos of my live lectures over Zoom. However, these video recordings are only available to the students who took these courses, mainly due to privacy concerns. If you are one of these students and want to rewatch these lecture videos, please visit the relevant ODTU Class page to access these recordings or contact me over e-mail.
