UCLA professor Randall Crane (whose blog you have in your RSS feed just before or after ours, right?) has posted a profile of Lisa Schweitzer, who got her PhD at UCLA, spent some time at Virginia Tech, and is now at USC working on issues of environmental justice and transportation. I got to hear Dr. Schweitzer present in Milwaukee last year, and although she admitted straight off that she was presenting on research (on hazardous waste-related disasters and environmental justice) she'd just begun, it was still a very interesting presentation. Her presentation style was relaxed, friendly, and confident, which can be difficult in a conference setting; that style may not be everyone's cup of tea, but it worked well for me.
And since the Chicago schedule is now posted online, I can now tell you that Dr. Schweitzer will be presenting at 9:45 am on July 8th, moderating a panel on measurements and techniques later that day, and helping with a roundtable on environmental justice (alongside Ann Forsyth) first thing Friday morning the 11th. Even if you are neither a transportation person nor an EJ person, I would recommend you check her out at some point.
(Standard doctoral-student disclaimer: Dr. Schweitzer is not on any committee of mine and is not reviewing any papers I have written.)
