[edit]Birth and education

He received baccalaureate and MS degree from the University of Alexandria before moving from Egypt to the u. s. to complete his PhD at the University of Pennsylvania with consultant Robin Hochstrasser. He completed a post-doctoral fellowship at the University of Calif., Berkeley with consultant Charles B. Harris.[1]
[edit]Academic career

After some post academic degree work UC-Berkeley, he was awarded a college appointment at Caltech in 1976, wherever he has remained since, and in 1990, he was created the primary Linus Carl Pauling Chair in Chemical Physics.[1] He became a naturalized subject of the u. s. in 1982.
Zewail has been appointive and can participate in President Barack Obama's Presidential Council of Advisors on Science and Technology (PCAST), Associate in Nursing consultative cluster of the nation's leading scientists and engineers to advise the President and vp and formulate policy within the areas of science, technology, and innovation.[2]
[edit]Research
Zewail's key work has been as a pioneer of femtochemistry—i.e. the study of chemical reactions across femtoseconds. employing a fast ultrafast optical device technique (consisting of ultrashort optical device flashes), the technique permits the de******ion of reactions on terribly short time scales - short enough to analyse transition states in selected chemical reactions.[3]
In 1999, Zewail became the tenth ethnic Egyptian to receive the laurels, following Egyptian president Anwar Al-Sadat (1978 in Peace), Naguib Mahfouz (1988 in Literature). Mohamed ElBaradei followed him (2005 in peace). different international awards embody the Wolf Prize in Chemistry (1993) awarded to him by the Wolf Foundation, the Tolman award (1997), the Henry Martyn Robert A. Welch Award (1997), and therefore the Priestley award from the yankee Chemical Society in 2011.[4] In 1999, he received Egypt's highest state honor, the Grand Collar of the Nile.
Zewail was awarded Associate in Nursing unearned academic degree by urban center University in Scandinavian country in might 2003 and could be a member of the Royal Swedish Academy of Sciences. Cambridge University awarded him Associate in Nursing unearned Doctor of Science in 2006. In might 2008, Zewail received Associate in Nursing unearned academic degree from Complutense University of Spanish capital. In Gregorian calendar month, 2009, Zewail was awarded Associate in Nursing unearned academic degree in arts and sciences by the University of Jordan.[5] In might 2010, he received a Doctor of Humane Letters from Southwestern University. His students embody scientists like Martin Gruebele
Zewail is married, and has four youngsters.
[edit]Political work

In his June four, 2009 speech at Cairo University, United States of America President Barack Obama proclaimed a replacement Science Envoy program as a part of a "new starting between the u. s. and Muslims round the world." In Gregorian calendar month 2010, Ahmed Zewail, Elias Zerhouni, and Bruce Alberts became the primary United States of America science envoys to Islam, visiting Muslim-majority countries from North Africa to geographical area.[6]
When asked concerning rumors that he would possibly contest the 2011 Egyptian presidential election, Ahmed Zewail said: "I am a frank man... I actually have no political ambition, as I actually have stressed repeatedly that I solely wish to serve Egypt within the field of science and die as a man of science."[7]
During the 2011 Egyptian protests he proclaimed his come back to the country. Zewail aforementioned that he would be a part of a committee for constitutional reform aboard Ayman Nour, Mubarak's rival at the 2005 presidential elections and a number one professional.[8] Zewail was later mentioned as a revered figure operating as a go-between between the military regime ruling once Mubarak's resignation, and revolutionary youth teams like the Gregorian calendar month half dozen drive and young supporters of Mohamed ElBaradei.[9]
