This week, we bring you two stories about the science of morality. Or morality in science. Either way you want to look at it. Part 1: Political scientist Ethan Hollander interviews a Nazi war criminal as part of his research. Part 2: As a graduate student, Cather Simpson is excited to present her work -- but then her adviser lies about it. Ethan J. Hollander is a professor of political science at Wabash College in Crawfordsville, Indiana. He is also the author of Hegemony and the Holocaust: State Power and Jewish Survival in Occupied Europe. Hollander’s published scholarship also includes research on democratization in Eastern Europe and on the Arab Spring. At Wabash, Dr. Hollander teaches courses on the Politics of the Middle East, Ethnic Conflict and Genocide, European Politics, and Research Methods and Statistics. He is a native of Miami Beach, and received his Ph.D. from the University of California, San Diego in 2006. When Cather Simpson graduated from high-school in the USA, she was certain she was going to become a neurosurgeon. She was very, very wrong. In her first year at uni, she discovered scientific research and got completely hooked. She is now a Professor of Physics and Chemical Sciences at the University of Auckland, where she started and directed a super-fun ultrafast laser lab called the Photon Factory. These days, she’s morphed into an entrepreneurial academic. The first company she co-founded, Engender Technologies, uses lasers to sort sperm by sex for the dairy industry. The second, Orbis Diagnostics, uses lasers for infectious disease testing at point-of-care – she is currently CEO there. The latest, Luminoma DX, uses light to screen more effectively for skin cancers. When she’s not enjoying the pleasure and satisfaction from using lasers to solve the knotty problems presented by Mother Nature, she’s doing 5000 piece puzzles and being “Schrodinger’s Mom” – simultaneously the world’s best and worst mother – to two lovely sons.
