Teaching Interests

Dr. Stewart's experience in teaching has been in a variety of settings within and apart from the School of Public Health. Most of his experience has occurred in the process of training and supervising a large number of students of biostatistics who have worked with Dr. Stewart on collaborative bio-medical research projects as graduate research assistants (GRAs). This activity has involved thousands of hours of direct, practical training and instruction in statistical methods, research database management, statistical computing, consulting skills, and scientific writing.

In addition, Dr. Stewart has directed the thesis research of seven students of biostatistics (BIOS 393 and BIOS 394) and has served as an active member of more that 30 other thesis committees. Dr. Stewart has also supervised the required practical consulting experiences (BIOS 242) of 15 students.

Dr. Stewart has also provided approximately 355 credit hours of instruction in the classroom setting (credit hours per student × number of students) and has provided tutorials and seminars to groups and clients in the Schools of Medicine, Dentistry, Pharmacy and Public Health and to other groups apart from the UNC system.
