INSTRUCTOR: Pascal Gagneux Ph.D. (Professor, Departments of Pathology and Anthropology)
The course will explore the major epidemiological transitions from ape-like ancestors to foraging tribes, farmers and pastoralists, to the global metropolitan primate we now are. We will focus on how diseases have shaped humans and how humans have shaped disease over time.

Statement on Academic Integrity:
“Academic Integrity is expected of everyone at UC San Diego. This means that you must be honest, fair, responsible, respectful, and trustworthy in all of your actions. Lying, cheating or any other forms of dishonesty will not be tolerated because they undermine learning and the University’s ability to certify students’ knowledge and abilities. Thus, any attempt to get, or help another get, a grade by cheating, lying or dishonesty will be reported to the Academic Integrity Office and will result sanctions. Sanctions can include an F in this class and suspension or dismissal from the University. So, think carefully before you act. Before you act ask yourself the following questions: a) is my action honest, fair, respectful, responsible & trustworthy and, b) is my action authorized by the instructor? If you are unsure, don’t ask a friend—ask your instructor, instructional assistant, or the Academic Integrity Office. You can learn more about academic integrity at academicintegrity.ucsd.edu” (Source: Tricia Bertram Gallant, Ph.D., UCSD Academic Integrity Office, 2017)
