Hi and welcome to the Photonics and Fiber Optics Lab at Kettering University,
My name is Corneliu (Cornel) Rablau, I am Associate Professor of Physics at Kettering. I hold a BS in Engineering Physics from the University of Bucharest, and a PhD in Physics from West Virginia University (1999). Prior to joining the Applied Physics group at Kettering University, between 2000 and 2003, I worked as Senior Fiber Optics Engineer at JDS Uniphase Corporation in San Jose, CA.
My general area of expertise, developed through my Ph.D. work and my industrial experience, is in Spectroscopy (Photoluminescence and Optical Absorption), and in Photonics and Fiber Optics Materials and Devices. My current research interest is at the interface between spectroscopy, photonics and fiber optics, on the one hand, and magnetic nanomaterials for technological and biomedical applications, on the other hand.
During the past three years I have performed extensive research on ferrofluids. Ferrofluids are colloidal suspensions of super-paramagnetic nanoparticles in a carrier liquid. In my research, I use the interaction of light with ferrofluids to investigate their properties in static and AC (RF) magnetic fields, relevant for potential applications. The magnetic-field induced optical signature (magneto-optic effect) of these nanomaterials is important both from a fundamental-physics standpoint, as well as from the standpoint of their medical and technological applications. Such applications include targeted drug delivery, enhancement agents for Magnetic Resonance Imaging (MRI), magnetic-field activated nano-heaters for loco-regional treatment of cancer through hyperthermia, and magnetic separation and manipulation in bio-pharma applications.
My research is performed primarily in the Photonics and Fiber Optics Lab I have established at Kettering, on custom-made experimental setups for magnetic-field-induced light scattering and magnetic hyperthermia measurements, and it is part of a larger research collaboration with the Magnetism and Magnetic Materials Group at Wayne State University. The unique strength and value my research at Kettering brings to this collaboration is the involvement of optical techniques, in general, and of photonic and fiber optics devices and equipment in particular, to facilitate these investigations. The experiments I perform at Kettering complement nicely the other characterization techniques applied at Wayne State University for the investigation of these nanomaterials. Optical techniques, in particular, are extremely important for the in-vitro and in-vivo imaging of tumors and for temperature measurements during hyperthermia. The fiber-optics temperature sensors involved in the hyperthermia experiments performed at Kettering are among the most accurate ways of monitoring this temperature.
During the past three years, this work on ferrofluids and on the associated development of fiber-optic sensors and optical techniques for these investigations has resulted in several papers published in major research journals and conference proceedings, as well as several conference presentations at regional, national and international conferences. A number of Kettering and non-Kettering students have been involved in this research, and have co-authored and/or presented this work at these conferences. Additional work is in the pipeline.
