Luís Carlos Costa Coelho received his graduation in Physics Engineering in 2006 and MSc in Instrumentation and Microelectronics in 2007 both by University of Coimbra in Portugal. At the Physics Department of the same University he developed research in Atomic and Nuclear Instrumentation with focus on gaseous scintillation counters towards high energy radiation. In this context he was directly involved in the international experience "Xenon Direct Dark Matter Search" at the National Laboratory of Gran Sasso in Italy, aiming search dark matter through the detection of weakly interacting massive particles. In 2010 he started to working in optical fibre sensors at the Optoelectronics and Electronic Systems of INESC Porto in Portugal, mainly applied to hydrogen detection under the project MICROPHYTE-Metabolic engineering of chlamydomonas and environmental optimization for hydrogen production and release. In 2016 received his Ph.D. degree in Physics at the University of Porto, Porto, Portugal with the focus on thin films technology applied to optical fibre sensors in collaboration with the now Centre for Applied Photonics of INESC TEC, Porto, Portugal. He?s research involves the study of coating types for gases and liquids detection, in particular hydrogen, for refractometers with surface plasmon resonance and for high refractive index samples monitoring with coated long period fibre gratings. He?s current research interests includes bio and chemical sensors based on thin film coating technology of particular structures as long period fibre gratings, fibre Bragg gratings, using surface plasmon resonance phenomenon. He is currently a Post-doc Researcher working in the project MARINEYE at INESC TEC ? A prototype for multitrophic oceanic monitoring developing sensors for dissolved carbon dioxide detection using colorimetric and refractometer platforms combined with new designs of optical fibre structures. In the last few years, he has published more than 47 papers in international journals with referee and over 35 papers in national and international conferences with more than 1350 citations and an h index of 13. He has been referee in a wide range of international journals as IEEE, OSA, SPIE, Elsevier, Pier, MDPI and Springer. He was also the president of the University of Porto SPIE Student Chapter in 2014 and a member of the organization team of the 9th Advanced Study Course on Optical Chemical Sensors and Biosensors (ASCOS 2015). Luis Coelho is a member of SPIE.
