After successfully passing the preliminary examinations, the student begins the process of specialization. As soon as possible, the student selects a dissertation advisor. A committee is formed to guide the student's subsequent progress toward the degree. Readiness to begin the dissertation is marked by completion of the qualifying examination, which should take place within 18 months after passing the preliminary examinations. Upon completion of the qualifying examination, the student advances to candidacy and begins work on the dissertation.
Preference is given to students who are able to pursue their studies primarily on a full-time basis.
The dissertation is based on independent research by the candidate and should constitute a significant original contribution to the area of biometry and statistics. The dissertation committee consists of at least three members, all of whom must hold the rank of assistant professor or above. One of the committee members must be from outside the Department of Biometry and Statistics. Outside readers may be included at the discretion of the committee. Each student is assigned an advisor who assists the student in selecting courses, a project and a dissertation topic.
