TEACHING
Courses, Training of Undergrad and Graduate Students and Post Doctoral Fellows:
Department of Biological Sciences Courses, University of Manitoba:
BIOL 3560
Comparative Animal Histology (Jan 1973 – June 2013) lab intensive. Taught until I took a half-time appointment (2014)
BIOL 4560
Microtechnique (Originally 22:440) 1974 until the present). An intensive 4th year honors level course, full compliment of lectures and intensive weekly labs plus individual student projects. (Sept – Dec).
BIOL 7230 (3CH)
Grad Course: Biology Special Topics: Advanced Microtechniques (involved the practical full scale teaching of light microscopy techniques). Taught most years.
BIOL 7600 (6CH)
Taught various times depending on demand. The course is on tissue preparation for light and electron microscopy.
Previous Courses Taught in Zoology before our merger with Botany:
In addition to teaching the Histology and Microtechnique courses since I was first hired I have also taught the following:
Taught in Invertebrate Zoology (formerly 22:341) for a number of years and directed the course for 2 years and other years (when Drs. Ward and Welch were course directors) was a contributing lecturer (6-8 lectures) on insects, and 2 labs with extensive live material 1973-1979 (when Dr. F. Ward was in charge). In 1980 I taught the course while Dr. Ward was on sabbatical, I introduced a number of labs featuring live material rather than preserved specimens.
Taught the 3th year Topics in Zoology Course (formerly 22:375) with Dr. Cass Lindsey (now retired at UBC) for approximately 4 years. Covered analysis of scientific literature, structure of publications, various research areas, communication; poster and conference presentation guidelines and also lectures on becoming a graduate student.
Subsequently when others were in charge of the course I continued to contribute some regular scheduled lectures in the Zoology Topics Course 22.375 - gave lectures on communication; posters and also research lectures.
Topics in Zoology formerly 22:450 (6CH) Co-taught the course with Dr. Cass Lindsey
1977 and 1978 involved extensive lecturing and an array of writing assignments and exercises for class size of approx 40-45.
1982 taught 3 weeks of a special summer course for Public School teachers for 1 summer Intro. – Intro. Biology 71:130 General Science Course for elementary school teachers contributed section on cells and tissues.
Zoology Honors Thesis Course formerly 22:411 (6CH) New course that, Dr. S. Sealy and I developed. We developed the proposal for this course and were in charge of the course the first year of its inception 1992-1993. In 1993-94 Dr. L. Graham and I ran the course. Subsequently the course was ran by a rotation of faculty from year to year
Proposed, developed and taught the Zoology 2nd year course in Developmental Biology for Honors and Majors (22:215) (had both lecture and labs with live material and experimental analysis) for a number of years. Subsequently the course was openen for general students and enrollemnt increased so much a lab was no longer feasible so only had lectures and tutorials. Thus we developed and taught the 3rd year intensive lab based Advanced Cellular and Developmental Biology course (formerly22:307) with Gunnar Valdimarsson to provide Majors and Honors students the lab experience.
I coordinated the Zoology 2150 Developmental Biology Course 2007-2008 after Dr. Vardimarsson died when the course was taught by Dr. E. McLachlan, a sessional instructor.
Graduate courses in the Zoology Department Taught numerous times for various students: Topics in Zoology and the Topics in Developmental Biology courses. Coordinated Grad courses formerly 22:734 and 735 (Dev. Biology)
Developed (with Dr. G. Valdimarsson) a 3CH course on Reproductive Physiology (course proposal approved) for the Nursing Mid-Wifery Program. Course put on hold as Midwifery program was not initiated due to government funding limitations.
Guest lectures in the Department of Entomology, Physiology course, 1977 for Dr. T. Galloway.
Department of Biology, McGill University:
1973
Was the invited co-instructor (with Dr. Nancy Wolfson, Biology, McGiIl University) in a one month intensive lab and field course in Marine Embryology: Experimental analysis of development of marine organisms for the consortium of Eastern Canadian Universities at the Huntsman Marine Laboratory, St. Andrews by the Sea, New Brunswick. I contributed the major part in the on-site organization of the course and organized and ran most of the labs. A few guest lectures were contributed by Dr. Joan Marsden (Biology, McGill) and Dr. Ruth Turner (Museum of Comparative Zoology, Harvard).
McGill University, Institute of Parasitology:
1971-1972
Macdonald College of McGill, Grad. Topics in Parasitology Course; I contributed six lectures on the structure and diversity of the integument of helminths. As well, research presentations were given in the Parasitology and insect physiology seminars were given in our weekly seminar and discussion group series.
DUFF ROBLIN BUILDING - FIRE RELATED SERVICE
The portion of the department in the Duff Roblin Building had a major fire in 2009 that had a huge impact. I was involved in various aspects of dealing with the Duff Roblin fire aftermath. As former Head of Zoology I had much familiarity with the facilities, labs, equipment etc. in the Duff Roblin Building. Due to the seriousness of the situation and toxic environment only a few individuals were to be selected for access to assist the companies (Clean Harbors, WFS, and LWG) handling the recovery process. I was one of four designated individuals (Lane Graham, Gary Anderson, Kevin Scott and myself) who were allowed into the building on an ongoing basis to access toxic areas and assist in dealing with the immediate and subsequent aftermath of the fire.
