Parasites are incredibly important. It has been said that there are more kinds of parasites than free-living organisms.
Parasites directly interact with ALL kinds of free-living organisms, including humans.
They are exceedingly important with respect to human health and economy. They also present many opportunities for scientific learning and understanding from molecular to ecosystem levels. My philosophy about teaching is that I want to share as much knowledge and understanding of the subject with students as possible. I also believe it is my job as instructor to challenge people. I want you to learn course materials because I care about you.
