Biographical details

Alvaro Casas Bedoya is currently a postdoctoral research fellow, the hybrid Integration deputy project leaderand, and the OSA/SPIE student chapter advisor in CUDOS. He received his PhD in physics from the University of Sydney in 2013 where he investigated photonic crystals and optofluidics. He received a double MSc degree in Photonics (through the Erasmus Mundus program) from St Andrews & Heriot-Watt universities in Scotland (2008) and Gent & VUB Universities in Belgium (2009) (Distinction level). His MSc research was based in Silicon-On-Insulator and photonic sensing architectures. He obtained a BSc. (Physics) (Hons) from Universidad del Valle in Colombia (2005) where he built a high power CW-C02 laser which was used for material processing.

Dr Casas Bedoya current research interests are based on design, simulation and fabrication of integrated optical circuits for stimulated Brillouin scattering, optomechanics, and sensing. He as an active member of international societies and belongs to the membership OSA council.
