Plenary Speakers

Prof. Scott DIDDAMS

Optical Frequency Measurements Group, National Institute of Standards and Technology (NIST)
Optical Frequency Combs for Clocks, Spectroscopy and Astronomy

Scott Diddams is a Fellow of the National Institute of Standards and Technology (NIST) where he carries out experimental research in the fields of precision spectroscopy and metrology, nonlinear optics, microwave photonics and ultrafast lasers.
He received the Ph.D. degree from the University of New Mexico in 1996. From 1996 through 2000, he did postdoctoral work at JILA, NIST and the University of Colorado. Together with colleagues at JILA, he built the first self-referenced, octave-spanning optical frequency comb and used it to produce carrier-envelope phase stabilized pulses, as well as carry out direct optical to microwave measurements.


Since 2000, Diddams has been a staff member at NIST. With his group and colleagues at NIST, he has continued the development of optical frequency combs and pioneered their use in optical clocks, tests of fundamental physics, novel spectroscopy in the visible and mid-infrared, and ultralow noise frequency synthesis.
In recent years, special attention has been given to high repetition rate laser-based and microresonator frequency combs, which are being explored for applications in microwave photonics and astronomy.
Dr. Diddams was a recipient of the Department of Commerce gold and silver medals for “revolutionizing the way frequency is measured” as well as the Presidential Early Career Award in Science and Engineering (PECASE) for his work on optical frequency combs. He is a Fellow of the Optical Society of America and the American Physical Society, as well as a Professor Adjoint at the University of Colorado.


Prof. Marcus MOTZKUS

Motzkus Group, Institute of Physical Chemistry, Universität Heidelberg
Treating complex molecules with complex femtosecond pulses

Marcus Motzkus is Professor of Physical Chemistry at the Ruprecht-Karls Universität Heidelberg. His research interests are ultrafast multidimensional time resolved spectroscopy on biological molecules and new materials for organic electronics, nonlinear optical microspectroscopy and coherent control.
He received his PhD in Physics from the Ludwig-Maximilians Universität (LMU) in Munich in 1994 and worked as a postdoc in the group of Ahmed H. Zewail at the California Institute of Technology. Between 1996 and 2002 he did his Habilitation work on “Coherent control of ultrafast quantum phenomena” at the Max Planck Institute for Quantum Optics, Garching, and LMU. In 2002 he was invited guest professor at the University of Franche-Comte in Besancon and lecturer at the LMU. In 2003 he became professor for physical chemistry at the Philipps Universität Marburg before taking charge of his current position in Heidelberg in 2009.
