Mohammed Tharwat Hassan Arabic: محمد ثروت حسن is a professor of physics and optical sciences at the University of Arizona in the United States.[1][2]

Early life

[edit]

Mohammed Tharwat Hassan was born on March 30, 1983, in Fayoum, Egypt. He received a Bachelor of Science degree in chemistry from Cairo University  (Fayoum Branch). Then in 2009, he received his master's degree from the National Institute of Laser Science (NILES)-Cairo University. He joined the Max-Plank institute for Quantum Optics as a Max-Plank fellow where he received his PhD  in attosecond Physics.[3][4]

Education[5][6]

[edit]
  • PhD Max-Planck Institute of Quantum Optics, 2013
  • MSc in Laser interaction with Matter Cairo University, 2008
  • B.S. Cairo University, 2003

Scientific achievements

[edit]

Earlier in his career, Mohammed  Hassan developed the light field synthesizer to generate the first optical attosecond pulse, the shortest light pulse documented in the Guinness World Records. Exploiting this tool, he was able to measure the time an electron takes to respond to an external light field.[7] Recently, he demonstrated the shortest, to date, electron pulse in an electron microscope.[8]

Currently, he is known for developing attosecond electron microscopy and attosecond electron diffraction (Attomicroscopy) to image the electron dynamics of matter in real-time and space.[9][10] He has a granted patent for his Attomicroscopy: Attosecond electron imaging and microscopy, US Patent, Application No.16394920.[11] Hassan research aims to image record movies of electrons in action.

Hassan and his group were able to demonstrate the attosecond optical switches and data encoding on laser pulses which paves the way to develop the ultrafast optical transistor and ultrafast optoelectronics.[12]


Awards and honors

[edit]
  • Max-Planck Research Fellow, 2009[5][6]
  • The Air Force's Young Investigator Award (YIP 2019).[5][6]
  • The Gordon and Betty Moore Foundation grant award to develop Attomicroscopy electron diffraction for imaging the electron motion in action.[5][6]
  • M. W. Keck research award for Science and Engineering in 2009.[5][6]
