I am a journalist with more than twenty years of experience covering biology and medicine, first as a staff reporter for the Ann Arbor Observer and then, since 1998, as a freelance writer.   My stories have appeared in Science, Nature, Technology Review, Nature Biotechnology, and Nature Medicine, and since 2000 I have been a contributing correspondent for the Journal of the National Cancer Institute (JNCI).  I live in Ann Arbor and enjoy exploring the north woods of Michigan and neighboring Ontario, on foot and on skis, in my free time.
