Announcements as of: Tuesday, August 23, 2017.

Wonderful Wednesday microbiology students! This site will be undergoing a massive update during the month of August, so please use the alternative microbiology site ( for current information.

Your first homework assignment can be found in the Bio. 4 Lecture Syllabus (see link below) and is entitled "Web-based Laboratory Assignment". Please use the version posted on the site. That said, there is information about the Biological Sciences Department that can only be found on this site, so you will want to access both.

Versions of the lecture notes and laboratory syllabus currently available on this site contain significant errors, so please use materials from the site until instructed otherwise. Thank you for your patients.

Important email reminder:
if you are a currently enrolled microbiology student, please use my exclusive, class "" email address (see class syllabus information) to contact me instead of the "" address listed elsewhere.
