How should you address me? Professor Cranor and Dr. Cranor are both fine if this is a professional context where titles are used. Outside of professional contexts you may use Dr. Cranor or Ms. Cranor. Please do not address me as Mrs. Cranor in any context. If we're not using titles, then Lorrie is just fine. If you can't decide whether to be formal or not, Professor Lorrie will also do. I use my full name Lorrie Faith Cranor in my publications, but no need to include my middle name elsewhere. Pronouns: she/her.

I have consulted for companies and non-profits on privacy policies, P3P, usable privacy and security, and technology policy. I have also served as an expert witness in patent litigation and in privacy cases, and in cases challenging the constitutionality of Internet harmful-to-minors laws, including the ACLU's successful challenge to the 1998 Children's Online Protection Act. I currently do expert witness consulting through Harbor Labs.


I spend most of my free time with my husband (Chuck), son (Shane), and daughters (Maya and Nina). I walk to work, practice yoga, take lots of photos, and design and create quilts. I also serve as an elected election judge, SciTech PTO President, and Dynamoms women's soccer commissioner.
