About

Christina Orphanidou, DPhil (Oxon)

I am a biomedical engineer with a background in applied mathematics; I have been developing signal processing applications for the last twelve years. In 2007, I obtained a DPhil (PhD) in Applied Mathematics from the University of Oxford, UK, and then continued working as a researcher at Oxford, firstly at the Phonetics Laboratory and then at the Institute of Biomedical Engineering. From 2008 until 2012 I was the lead Engineering Research Assistant on the Hospital of the Future project, investigating real-time vital-sign monitoring (heart rate, oxygen saturation and breathing rate) of high-risk, ambulatory patients using wireless sensors. Through this project, I gained hands-on experience in analyzing data from several body-worn sensor systems commercially available in the UK (e.g. from Intelesens and Hidalgo) and in the US (Proteus patch). Most notably, I have developed Signal Quality Indices for identifying motion-corrupted data from which no clinical decisions should be made, as well as algorithms for extracting respiratory rate from a pulse oximetry finger probe and the electrocardiogram. I left Oxford, moved to Cyprus, and in 2013 I founded Oxygen Research with the aim of using my expertise in order to help sensor developers and other medical technology organizations with their signal processing and data analysis.  My full professional bio can be found on my LinkedIn page here
