Kathy Barker's second book, At the Helm: Leading Your Laboratory, is now available in an updated second edition that focuses specifically on the challenges that new principal investigators face in getting their labs up and running. Fresh topics in the new edition include "collaboration contracts, performance evaluations, communicating with non-scientists, tips for succeeding on the tenure track, and professional development," according to a Cold Spring Harbor Press statement. "The world has changed since the first edition of 'At the Helm' was published in 2002," Barker writes, "and the laboratory has changed with it, for better and worse." Barker's content is based on interviews with PIs and their anecdotal advice.
