I work in environmental engineering. What do you do for work?
Environmental engineering sounds awesome! I work in nuclear engineering. How long have you been working as an environmental engineer?
I have been working as an environmental engineer for about 10 years now. Do you know much about my work? Congrats about working in nuclear engineering.
Thank you. I actually don't know a lot of specifics on environmental engineering science. What specialty do you work in?  
Environmental engineering basically protects the world from potentially deleterious effects of natural and human activities
That's so great, it seems like as an environmental engineer you are doing amazing work. What kind of courses did you have to take for the degree?
It involves waste water management, air pollution control, recycling, waste disposal, radiation protection, industrial hygiene, animal agriculture, environmental sustainability. Lots of science classes. 
That's a lot of engineering education! How did you like the class on radiation protection? 
I enjoyed the class, but it was super hard. Radiation is nothing to play with!
