My teaching experience began when I found myself director of a biotechnology training program at Seattle Central Community College in the early 90's. Since there wasn't any curriculum available, I wrote all the biotechnology lab manuals and taught courses in genetics, immunology, media and solution preparation, biotech lab courses, and microbiology. Today, I have my own company, Digital World Biology. We produce free tutorials on using bioinformatics, offer professional development for teachers in bioinformatics, and develop instructional materials. I also teach an on-line course in bioinformatics for Austen Community College in Texas and another bioinformatics course at Shoreline Community College in Washington State. I write about science and teaching at ScienceBlogs. My blog is Discovering Biology in a Digital World.
