My academic background is in Physics, and Nuclear Medicine and Radiobiology. During my graduate studies I specialized in photonics, concentrating on ionizing effects of laser pulses on different materials. This experience enabled me to integrate radiation science with photonics, and provided me with a unique and valuable expertise.

 

EDUCATION

TECHNICAL EXPERIENCE

  • Designed and operated experimental setups for interferometry, and pump-probe time resolved spectroscopy.
  • Conducted time resolved fluorescence experiments.
  • Maintained, calibrated, and operated a femtosecond laser system (from SpectraPhysics), an optical parametrical amplification system (OPA), and an ultra-short light pulse amplification system (Spitfire).
  • Designed and operated a detection/analysis system for a pulsed laser system.
  • Hands-on experience with data acquisition systems such as Boxcar, National Instruments DAQ hardware, and GPIB & RS232 protocols.
  • In-depth knowledge of LabView programming.
  • Experience with diamond film deposition in a surface-wave driven microwave plasma reactor.

SCIENTIFIC SUBJECTS EXPLORED IN-DEPTH

  • Laser material processing; applications of pulsed lasers in medicine and biology; ionizing effects of laser radiation on water, and biological targets (the physical processes involved and the resultant chemical and structural transformations); nonlinear optics; spectroscopy.

APPLIED RESEARCH AND INNOVATION

  • Currently developing a laser-based system that enables the study of DNA damage formation, and DNA repair machinery, with femtosecond time resolution.
  • Currently developing a laser-based material processing system; the dose distribution is controlled by inducing a superposition of ionization modes.
  • Description of water photoionization using femtosecond laser pulses at 790 nm, in self-focusing regime.
  • Proposed new and promising applications of pulsed laser sources in the field of radiobiology and radiochemistry.
