My name is Shai ('shy') Lynne Nielson (she/they) and I received my joint PhD in Linguistics and Cognitive Science from UC San Diego. I am a hearing L2 signer of American Sign Language (ASL) and my research focuses on late first language acquisition and phonological processing in ASL. If you would like to learn more, please check out my research page.
In addition to my research, I am an active advocate for equitable and student-centered higher education and was the co-creator and co-facilitator for the Anti-Racist and Inclusive Linguistics Pedagogy Program at UCSD. You can find out more about the program and my education training on my teaching page.
You can also look at my CV, find out how to reach me, and see what I've been up to lately (see Announcements below).
