According to her bio in Wikipedia...
(( https://en.wikipedia.org/wiki/Christine_Blasey_Ford#cite_note-NYT26Sep2018-4 ))
It states that in 1996 she received a PhD in "Educational Psychology" from the University of Southern California.
However, I did a thorough search of USC Commencement Programs (The 112th:1995), (The 113th:1996), and (The 114th:1997) all three commencement exercises were held at Alumni Memorial Park. They are available in the USC Digital Library's "Subcollections" section, under "Commencement Programs".
I used the "text" search feature, and none of these three Commencement Program documents (containing lists of each year's graduates) had a Christine M. Blasey, or a Christine M. Ford, or combinations thereof, receiving anything. Her name simply does not appear in those three year's lists of graduates.
Furthermore, her USC doctoral dissertation, identified in Wikipedia as "Measuring Young Children's Coping Responses to Interpersonal Conflict", does appear in the USC listings of dissertations, in the USC Digital Library, in the Dissertations and Theses subcollections.
The title page states that it was prepared "in partial fulfillment of the requirements for the Degree of Doctor of Philosophy (Counseling Psychology), August 1995". This is inconsistent with the Wiki page which states the PhD was in "Educational Psychology". In my mind there is quite a difference between "Counseling" and "Education", but what do I know, I'm only an electronics engineer.
The dissertation looks like a typical attempt to make a science out of something that isn't. Putting numerical analysis to work on something that is decidedly un-numerical, i.e., children. 130 pages of gobbledy-gook.
In summary, after 23 years, who knows if the dissertation is legit. USC lists over 55,000 dissertations, and that's only one school. Second, it was in "Partial fulfillment" meaning she may not have completed all the requirements for the degree, i.e., course work, teaching, experimentation, etc. So, who knows why she isn't listed as receiving the degree. Still, something is obviously wrong somewhere.
Again, sincerest apologies.
No apology needed. You came to the conclusion after your own research - which I applaud. Thank you for the diligent research and the great summary!
