Introducing Sarah Middleton Williams...

I am a doctoral candidate in the Department of Civil & Environmental Engineering at Stanford.

I received my Bachelor of Engineering (Civil & Environmental Engineering) in 1995 from the University of Michigan, then came to Stanford where I completed my MS in 1998. My research focuses on biological hexavalent chromium, Cr(VI) and chromate remediation.

When not in the lab, I try to get as much fresh air as possible. I love to hike, backpack, and mountain bike. I also teach a creative writing class for elementary school kids in East Palo Alto.
