 Hello, my name is Jan Oliver Walgrim and I know that name tends to be a bit difficult to pronounce for non-Germans, so I also simply go by the name Joe. My way into the realms of spatial data and spatial algorithms started in the late 1990s when I as a master and then PhD student at Informatics worked on building some rather weird looking autonomous mobile robots that used lighter data and cameras to learn to navigate. And that was basically using methods that these days we find in robot vacuum cleaners or self-driving cars for example. I quickly became interested in applying these methods for merging and matching data to geographic data. And then over time I turned into what I would call myself today namely a geoscience researcher and teacher working at the interface between spatial algorithms and human spatial cognition and more recently also the application of immersive technologies. I always enjoyed teaching and working with students, but I quickly realized that teaching in our online program is a particularly rewarding experience simply because of how motivated and eager to learn our students are. And well frankly there's nothing more motivating and rewarding for me than when students after the class write to me and tell me they were able to immediately apply what they learned in their job or for their research. So when I had to leave Penn State and return to Germany well I basically did everything I could to remain an instructor in the program and fortunately that worked out rather well. I'm now here living next to Hamburg and that is 6 hours ahead of US East Coast time. So that means when students in the US get up in the morning I typically already had a couple of hours to go through emails and forum posts and answer any questions. Alright thank you for your interest and if you have any questions about any of my courses please don't hesitate to contact me.
