I remember it distinctly and as if the world were about to change. President Obama had taken office – the excitement was palpable – and I was about to teach my first semester as a Clinical Assistant Professor at the University of Pittsburgh School of Law in their wonderful Environmental Law Clinic. On the same day that I turned 30, Lisa P. Jackson was confirmed as the President’s first U.S. EPA Administrator. Her message to the U.S. Senate Committee on Environment and Public Works was simple and impactful: “If I am confirmed, I will administer with science as my guide.”
