DESCRIPTION:Prof. Rafael Piestun\,\nDepartment of Electrical and Computer 
 Engineering and Department of Physics\, University of Colorado Boulder\, U
 SA\nThe seminar will take place in ELA 2 and will be simultaneously broad
 casted in the main auditorium in Neuchâtel Campus (MC A1 272).\n\nCoffee
  and cookies will be served at 13:00 before the seminar\, in front of the 
 two auditoriums. \n\nAbstract\nOptical computational imaging seeks enhanc
 ed performance and new functionality by the joint design of illumination\,
  unconventional optics\, detectors\, and reconstruction algorithms. Among 
 the emergent approaches in this field\, two remarkable examples enable ove
 rcoming the diffraction limit and imaging through complex media.\nOvercom
 ing the diffraction resolution limit has enabled unprecedented opportuniti
 es for optical imaging at the nanoscale. Fluorescence imaging using photoa
 ctivatable or photoswitchable molecules within computational optical syste
 ms offers single molecule sensitivity within a wide field of view. The adv
 ent of three-dimensional point spread function engineering associated with
  optimal reconstruction algorithms provides a unique approach to further i
 ncrease resolution in three dimensions. \nFocusing and imaging through st
 rongly scattering media has also been accomplished recently in the optical
  regime.  By using a feedback system and fast optical modulation\, it i
 s possible to mitigate the effects of multiple scattering upon propagation
  through the medium. Advanced holographic techniques for phase-control he
 lp characterize the scattering media at high-speed using micro-electro-mec
 hanical technology\, allowing focusing through a temporally dynamic\, stro
 ngly scattering sample\, or a multimode fiber.\nIn this talk we explore th
 e prospect of these techniques in biological imaging.\n \nBio\nProf. Rafa
 el Piestun received the Ingeniero Electricista degree from the Universida
 d de la República (Uruguay) and MSc. and Ph.D. degrees in Electrical En
 gineering from the Technion – Israel. From 1998 to 2000 he was a researc
 her at Stanford University. Since 2001 he has been at the University of Co
 lorado Boulder. Professor Piestun is a fellow of the Optical Society of Am
 erica\, was a Fulbright scholar\, an Eshkol fellow\, received a Honda Init
 iation Grant award\, a Minerva award\, a Provost Achievement Award\, and E
 l-Op and Gutwirth prizes. He was associate editor of Optics and Photonics 
 News and Applied Optics. He is a co-founder of the company Double Helix Op
 tics (SPIE Prism Award\, First Place in the Luminate Competition) and the 
 company Modendo Inc. His areas of interest include computational optical 
 imaging\, superresolution microscopy\, volumetric photonic devices\, scatt
 ering optics\, and ultrafast optics.\n
