Marcus Holloway

Science Educator & Microbiology Writer

I'm a high school biology teacher with fifteen years in the classroom, where I've spent countless hours helping students understand the often-confusing world of microorganisms. My passion is breaking down complex microbiology into clear, memorable concepts—especially the practical side of why bacteria thrive in some conditions and not others. Outside the classroom, I'm an enthusiast of food science and kitchen experiments, and I volunteer with our local health department on community food safety workshops. I have a rescue dog named Petri who sits patiently while I plan lessons.
