Research and teaching

Research activities

Dr. Liang’s goal is to disrupt the silos of the Internet of Things by creating, using, and implementing open and interoperable standards for device-cloud communications and cloud-cloud communications. He is currently the Standard Working Group Chair of the Open Geospatial Consortium SensorThings API. The OGC SensorThings API is an OGC candidate standard for providing an open and unified way to interconnect IoT devices, data, and applications over the Web. The SensorThings API is an open standard, builds on Web protocols and applies an easy-to-use REST-like style. The result is to provide a uniform way to expose the full potential of the Internet of Things.

Dr. Liang’s general research area is Geospatial Information and Communication Technology (GeoICT). Currently, his specific research interests lie at the intersection of geo-sensor networks, distributed computing and cyberinfrastructure, specifically in the area of the Sensor Web, which is a geospatial information infrastructure connecting heterogeneous sensor networks.


Dr. Steve Liang completed a bachelor of science in Surveying Engineering at National Cheng-Kung University, Taiwan in 1999, and earned his doctorate in Earth Space Science at York University, Toronto in 2007. During his doctorate studies, he contributed to the development of one of the first virtual globe systems in the world, called GlobeView. GlobeView was later commercialized by GeoTango Corp., and subsequently acquired by Microsoft in 2005.

Dr. Liang is currently an associate professor at the University of Calgary and director of the GeoSensorWeb Laboratory. He is also the founder and CEO of SensorUp Inc, a Calgary startup company that offers a Data Exchange Platform based on International Open Standards for the Internet of Things. In 2013, he was chosen one of Calgary’s Top 40 Under 40 by Avenue Magazine. Dr. Liang has been an invited speaker at universities and industries in 11 countries, and held the AITF-Microsoft Industry Research Chair on the Open Sensor Web from 2011 to 2014.
