Biography - +

Kawal Sawhney is the Principal Beamline Scientist for Diamond’s Test beamline B16 and is also the head of the Optics and Metrology Group.

Educated in India, he undertook post-doctoral work in the field of X-ray Optics at BESSY-II in Germany. Prior to joining Diamond in 2004, Kawal was the head of the Beamlines Section at the Indian synchrotron facilities Indus-1 and Indus-2, where he oversaw design, construction and operation of several beamlines.

His main interests are in designing beamline optics and carrying out research in the field of x-ray optics and metrology.
