I worked before as a freelancer writer where I would review some tech products (phones, websites, online services... etc) and post them on YouTube (channels which I do not control), and both my voice and picture were appearing in these videos.
Now that I graduated from my Masters program, I want to pursue my PhD and teach in the university. I would like to start publishing some papers as well in my field.
However, my past online identity is haunting me; Anyone can search my name and instead of finding my Google Scholar page as the first result, they would see me talking about the features of iPhone 7 in a YouTube video, and it is embarrassing for me. Some political articles that I published online are also embarrassing for me as I enter the academic world.
Do most people in academia suffer from the same thing? How can one get rid of this past online identity before entering the professional academic life? And how can I be sure no one uses parts of this old identity against me in the future?
