I'm a PhD candidate in analysis (harmonic analysis). I have a Master of Science degree in mathematics (analysis). My email address is jonasteuwen@gmail.com. And my [Google Scholar profile](http://scholar.google.com/citations?user=Jz3tRZMAAAAJ). (I agree, not much there yet. Should change soon!) I would appreciate it if you would correct my spelling and grammatical errors.
