To promote cross-disciplinary research and collaboration, the Burroughs Wellcome Fund in Research Triangle Park, North Carolina, has created travel awards of up to US$15,000 each for US and Canadian citizens or permanent residents. Applicants should hold or be pursuing a PhD in chemistry, physics, mathematics, computer science, statistics or engineering, and want to investigate biological questions with another lab or through attending a course. Biologists looking to collaborate with, or learn from, a physical scientist can also apply. The funds are for travel expenses anywhere in the world by the end of 2012. The deadline is 1 December 2010; winners will be announced by 1 March 2011.
