Clarity needed here

A sentence in the introductory section reads as follows:

"He then moved to University of Strasbourg, then he followed Charles Ehresmann in Paris, where he received his Ph.D. degree in 1958."

The phrase "he followed Charles Ehresmann in Paris" is not standard English.

Does it mean that he moved to Paris along with Ehresmann?

Does it mean that he studied under Ehresmann in Paris?

(In any case: At what Paris institution did this occur?)

I hope someone familiar with this subject can write this more clearly in English.
