Professor Mark Nicholas Gahegan

PhD (Curtin University), BSc (University of Leeds)

Biography

I have worked as a delivery boy, fitness instructor, musician, and software engineer so geography seemed the next logical choice.

My research interests are broad, covering most aspects of GIS, visualization, philosophy of science, semantics and pragmatics, e-science, representation of scientific knowledge, geocomputation, digital remote sensing, artificial intelligence tools, spatial analysis, Voronoi diagrams, spatial databases and algorithms, and spatial reasoning. This is because I can never sit still for too long and am easily distracted................Oh, yes, I've also dabbled in mineral potential mapping, epidemiology, habitat analysis, bio-informatics, e-learning and predicting land-cover change.

While at Penn State University I was involved in a number of funded research projects, from ontology capture to spatial epidemiology. I also directed a new Professional Masters degree program in GIS www.worldcampus.psu.edu/MasterinGIS_GIS.shtml, developed at the Dutton e-Education Institute www.e-education.psu.edu at Penn State, and delivered through World Campus www.worldcampus.psu.eduhttp://www.worldcampus.psu.edu.

In whatever spare time is left over after family, work and trying to keep in shape, I play guitar in a local band.

Research | Current

My research interests cover most aspects of GIS, visualization, philosophy of science, semantics and pragmatics, e-Research (e-Science), representation of scientific knowledge, geocomputation, digital remote sensing, artificial intelligence tools, spatial analysis, Voronoi diagrams, spatial databases and algorithms, and spatial reasoning.

I direct the Centre for eResearch, a group that aids researchers to tackle challenging computational research by providing scientific computing and software engineering expertise, patternable services such as virtualised compute platforms, research data services, visualisation and analytics, and educational offerings to upskill the research community.

Postgraduate supervision

I have been advisor to completed 9 Ph.D. and 7 Masters students, with more currently underway. I greatly enjoy working with research students, it is one of the best things about my job.
