William Ghiorse

A veteran educator and editor, who has extensive research experience in Geomicrobiology, Biogeochemistry and Environmental Microbiology.

Research Focus

My major resarch focus has been geomicrobiology and biogeochemistry of Mn-oxidizing bacteria. I have also done pioneering research on deep subsurface and groundwater microbiology and, more recently on the survival and fate of Cryptosporidium parvum in the NYC watershed.

Outreach and Extension Focus

Past outreach activities include occasional involvement with parties interested in survival and transport of pathogens (Cryptosporidium oocysts) in the New York City watershed.

Current activities include outreach education for the general public including a short course at Lifelong, the local senior citizen center on microbes and their importance in everyday life

Teaching Focus

I taught a large undergraduate course in General Microbiology which is taken by students of Biology, Engineering Nutrion, Animal Science, Food Science.
Since 2012 I have taught an outreach course at Lifelong, the Senior Center in Ithaca , NY
