I am an American expat in the Czech Republic. I am a part-time ESL teacher, and a full-time staff researcher for the Academy of Sciences of the Czech Republic, Institute of Physics. I specialize in HR-S/TEM and computer simulation thereof.
As an aside, my favorite website is MIT's OpenCourseWare, which I use extensively to learn as much as I can in my spare time and I highly recommend it for other people to do the same.
