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 asNature, the Journal of Fluid Mechanics, the Journal of Experimental Biology, and PNAS.

Nigerian scientist receives $500,000 MacArthur grant

John Dabiri, a 30-year-old Nigerian biophysicist and Associate Professor of Aeronautics and Bioengineering Division of Engineering and Applied Science with the California Institute of Technology has being named among 23 new Fellows of MacArthur foundation for 2010, with each receiving a $500,000 "genius" grant.

The funds will be provided as a "no strings attached" support for the next five years. The MacArthur fellowship offers an unusual level of independence without stipulations and reporting requirements and unprecedented freedom on how to use the fund, thereby allowing recipients to "reflect, create, and explore" to underscore the spirit of freedom intrinsic to creative endeavours. Nigerian writer, Chimamanda Adichie, was a 2008 recipient of the MacArthur grant.


His work

Mr Dabiri works 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. His biography, according to the foundation, reveals that "he studies some of the simplest multicellular organisms, jellyfish, which propel themselves by contracting cells in their bell-shaped outer skin and generating jet forces in the tail end, with tentacles trailing behind.

"His research 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). The research is believed to have 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."

Mr 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 journals such as Nature, the Journal of Fluid Mechanics, the Journal of Experimental Biology, and PNAS.

Thanks Augustine.


Your thoughtful points are much appreciated.
The idea of a workshop is also very good.

I would like to take the liberty to hope that I will not be seen as all talk and no action if I beg not to have to participate even though its a good idea.My experience with the conference initiative convinces me that I might be  too wrapped up with the backlog of things I must do  to be of much use in group initiatives apart from posting things to the group.I am only too willing to give any help I am able to give,though.

I look forward to being in Nigeria and  investigating some of these claims of wonders myself.

I expect the self described jet inventor has actually produced something,if only a diagram.I also suspect he believes in his own claims.I doubt if the environment he is operating in is one where there is likely to be much profit in making such claims if he does not believe that he is correct.Oyibo is able to generate credibility among people who do not examine his claims carefully because of   his level of academic certfication-a PhD,the further symbolic capital from his being a published academic and one based abroad.

The man who claims the jet engine innovation does not have any of those enablements.

thanks
toyin

  Toyin
 Thanks for this report. More power to your elbow
  Remember I stated we have that problem with Science Jourmalism. I think this report was by the Sun Newspaper. Do they have a science and Tech Editor?. When was the first Newspaper published in Nigeria?. Was it 18 something in Abeokuta? And the first Science Faculty in Nigeria? 1948. I think whats missing from the report is EXPERT OPINION.Sure we do not have Jet Propulsion engineers in Nigeria but in this age of Information technology such people are just a click away. A physicist or Mechanical engineer from one of the Nigerian universties could have been consulted

This young  man had probably just read a book some where which he assumes nobody else has acess to and he is now claiming to be an Inventor.He should perhaps go back to school and take his  maths and physics more seriuosly.
He seems obviuos he has been reading about some personalities in Science who at first were not taking seriously. I take the example of Robert Goddard father of American Rocketry sneered out even by Journalists and the rest is history



 Please I want to suggest here that this Society., I mean Wole Soyinka society should help to organise a workshop on Science and Technology Journalism.We still have not got it right in Nigeria.In my own opinion None of the Papers get it right. Look, our Science editors do not know the difference between ASTRONOMY and ASTROLOGY,Nuclear reactors and Nuclear reactions and now Jet Proportioned instead of Jet Propulsion.
This boy maybe yet another Dr or Professor Gabriel Oyibo. His Science may be correct but he claims might be false
 If he has an invention then he should register it at Patent office. And there is really no big deal about registering  Patents many of such do not get to the market place.

Toyin,

That's what worries me about this case. What's a well "proportioned" jet
system? If the young man cannot employ the right scientific terms, how
are we sure his claims are well founded?
