Interesting career as an environmental engineer, mostly in manufacturing. Fairly decent chemist! I a history buff and so enjoy (and write) historical fiction, of which "The Good Harvest" is best...see it on Amazon. I am also a futurist, and I think the must disruptive technology in the next five decades will be biology...this makes a good stew in which to brew SF stories. See Smart Kat or Good Insurance for two good long books, both on Amazon.
