I haven't heard of any Nepali professor there either, you might have heard about teaching assistants to engineering professors. It is pretty affordable once you are eligible for instate tuition. Engineering department is pretty good. Louisiana Tech also just awarded the first bachelors degree in nanosystems engineering in the United States (if you're interested in nanosystems)..
Hope this helps...
But there are a lot of Nepali students there... and it is rumored that 60 more are coming from Nepal in the fall + many more transfers from other universities...

Do your research on whether the particular engineering degree you are looking for is any good at La Tech before transferring

Good luck!
