He needs to keep HIS religion out of the classroom--especially the science classroom.

Made me think... but I have probably learned more in his microbiology/gen. class then I have in any other science class! He is hysterical and is always willing to talk more about any scientific topic!

I had him as a freshman for biology and didn't like the class at all. Then I took him as a junior for Honors Microbiology/Genetics and I totally loved the class. He works way better with upperclassman

He's very passionate about what he teaches, but always goes off on some religious tangent, which can be offensive. But he's kind and his class is easy to get through.

His remarkable determination to push the greatest discoveries of our time into the minds of America's future can only be matched by his passion for the subject itself.
