Great news! Nigerian-American Biophysicist, John Dabiri has recently won the prestigious $500,000 MacArthur Fellowship! As you may recall, Nigerian writer, Chimamanda Adichie won the fellowship as well in 2008. Get inspired! Watch the video below and read his bio.

Name: John Dabiri
Associate Professor of Aeronautics and Bioengineering
Division of Engineering and Applied Science
California Institute of Technology
John Dabiri is a biophysicist whose work draws on a wide range of fields—including theoretical fluid dynamics, evolutionary biology, and biomechanics—to unravel the secrets of one of the earliest means of animal locomotion. He studies some of the simplest multicellular organisms, jellyfish (medusae), which propel themselves by contracting cells in their bell-shaped outer skin and generating jet forces in the tail end, with tentacles trailing behind. From a theoretical engineering perspective, he has shown that elucidating the mechanisms of locomotion depends on detailed mathematical analysis of the fluid vortex rings that jellyfish form in the surrounding water by contracting their bell; his results significantly increase our knowledge of the impact of size and speed on the formation of optimal vortex rings. Because the relative impact of viscosity on propulsion decreases with greater size, fluid dynamics theory implies that rowing becomes a more efficient means of locomotion as animals grow larger. Dabiri and colleagues confirmed this experimentally by examining propulsion during maturation and in adult specimens of varying size across hundreds of species, and they also found that a hybrid jet-paddling motion brings the advantage of drawing nearby prey into the bell, where the tentacles can capture them. Dabiri has invented a method that allows divers to use tiny reflective particles to visualize, with high speed and fine spatial resolution, the fluid dynamics of propulsion by jellyfish in their native habitats; this technique provides a wealth of new data that can be used to test and refine models of vortex behavior. Dabiri’s research has profound implications not only for understanding the evolution and biophysics of locomotion in jellyfish and other aquatic animals, but also for a host of distantly related questions and applications in fluid dynamics, from blood flow in the human heart to the design of wind power generators.
John Dabiri received a B.S.E. (2001) from Princeton University and an M.S. (2003) and Ph.D. (2005) from the California Institute of Technology, where he is currently an associate professor of aeronautics and bioengineering. His scientific articles have appeared in such journals as Nature, the Journal of Fluid Mechanics, the Journal of Experimental Biology, and PNAS.

About the MacArthur Fellowship
The MacArthur Fellows Program awards unrestricted fellowships to talented individuals who have shown extraordinary originality and dedication in their creative pursuits and a marked capacity for self-direction. There are three criteria for selection of Fellows: exceptional creativity, promise for important future advances based on a track record of significant accomplishment, and potential for the fellowship to facilitate subsequent creative work.
The MacArthur Fellows Program is intended to encourage people of outstanding talent to pursue their own creative, intellectual, and professional inclinations. In keeping with this purpose, the Foundation awards fellowships directly to individuals rather than through institutions. Recipients may be writers, scientists, artists, social scientists, humanists, teachers, entrepreneurs, or those in other fields, with or without institutional affiliations. They may use their fellowship to advance their expertise, engage in bold new work, or, if they wish, to change fields or alter the direction of their careers.
Although nominees are reviewed for their achievements, the fellowship is not a reward for past accomplishment, but rather an investment in a person’s originality, insight, and potential. Indeed, the purpose of the MacArthur Fellows Program is to enable recipients to exercise their own creative instincts for the benefit of human society.
The Foundation does not require or expect specific products or reports from MacArthur Fellows, and does not evaluate recipients’ creativity during the term of the fellowship. The MacArthur Fellowship is a “no strings attached” award in support of people, not projects. Each fellowship comes with a stipend of $500,000 to the recipient, paid out in equal quarterly installments over five years.
