Science and the L'Oréal Foundation have teamed up to produce this e-booklet focusing on 16 women in five different areas of biology research: microbiology, immunology, virology, neuroscience, and molecular biology. The essays about these scientists give you an idea of the differences and similarities between their jobs as well as some insights into their personal triumphs and struggles as they have built successful and meaningful careers. The interviews span the career spectrum from new scientists to more established researchers who have experienced the many ups and downs of a life in biology research. The booklet also is available from the Science Careers site as a pdf.
