Dr. Khoo is internationally known for his pioneering and leading work in liquid crystals, and in nonlinear optical phenomena and applications. Since joining Penn State in 1984, he has established and directed the Nonlinear Optics and Liquid Crystal Research Laboratory. Over the years, his laboratory has received research funding from various Government agencies including:- the National Science Foundation, Defense Advanced Research Projects Agency, Navy Air Development, Air Force Office of Scientific Research, Air Force Phillips Laboratory, and the Army Research Office. Prof. Khoo is a Fellow of the Optical Society of America, IEEE and the UK Inst.itute of Physics. He has previously served a three-year term as Vice President of Technical Affair for the IEEE-Lasers and Electro-Optics Society and as Chair of the United States Advisory Committee/International Commission for Optics of the US National Academies. He is the author, co-author of over 600 technical publications and several books on nonlinear optics and liquid crystal optical physics. Ongoing research activities in his laboratory and collaborative research programs are centered on nonlinear and electro- optical properties of liquid crystals and nano-structured novel refractive metamaterials, and studies of optical wave mixings, optical switching and modulation, optical limiting and sensor protection enabled by unique properties of these optical materials.
