Current Scholars, Fellows, and Students in the Laboratory

Individuals appointed to the Laboratory are doing research in the fields of statistics, psychometrics, measurement, and research methodology under Professor Zumbo's direction.  Students working in the MERM field under my direction have a formal title with the Edgeworth Laboratory:

 

Research Fellow is a title awarded to a person appointed to the Laboratory allowing for advanced study or research (typically a Masters Level Student in MERM).

 

Research Scholar is the title for one who has done advanced study in a special field (typically a doctoral student who has completed a masters thesis), and is advancing toward their doctoral candidacy.

 

Senior Research Scholar is a Research Scholar who has passed their doctoral candidacy -- comprehensive exams, doctoral proposal, and completed all of their required course work for the Ph.D.. They have only their dissertation to complete for their doctorate.

Here is a list of Professor Zumbo's current graduate students who are active members of the Lab:
