Following an early career in industry as a Sr. research scientist  working in the fields of ultrafast lasers, optical communications, and materials processing, I joined the Center for Ultrafast Optical Sciences (CUOS) to explore light transmission through highly scattering media through light manipulation or wavefront shaping. This newly emerging field of optical wavefront shaping involves the ability to manipulate light fields both spatially and temporally. It has largely been enabled by the availability of spatial light modulators (SLM). SLMs are used to create arbitrarily complex light fields that are now powerful elements of the optics toolbox. An SLM also provides means to manipulate the fundamental constituents of classical light or single photons, which obey the laws of quantum physics.

In my research, i will be using these new tools to explore novel ways to address topics where conventional optical techniques are hard to apply, such as the control of light propagation in biological tissues, complex photonic structures, plasmonic systems, and multimode fibers.

My research will also directly address the core problem of entanglement degradation by developing methods to create and manipulate entangled light fields carrying orbital angular momentum (OAM) and related structured light fields. The light fields are manipulated using wavefront shaping techniques in  waveguide e.g. multimode fibers in order to overcome environment induced destruction of coherence.
