I've shared a written bio with a strong emphasis on my academic experience and qualifications. I outline office hours and share my email for students to reach out to me.
I posted a short video sharing what excites me about this course and what they can expect. Supporting this video are some more details about who I am, this might include what I am currently reading or a hobby I'm pursuing, and what inspired me to pursue my academic career along with some highlights. I've made it clear when and how students can reach me via email, chat, phone, or text.
