Kirsten Rosselot is a licensed professional chemical engineer and a member of AIChE. She's been an environmental consultant for over 20 years and specializes in assisting clients with questions that thermodynamics can help answer. Her clients often need help with understanding emissions or releases that are technically difficult to estimate or with determining which of the substances or processes at their facility should be the focus of reduction, efficiency, and/or substitution efforts. For many years, she's been a regular member of technical peer review panels for EPA scholarships and SBIR grants. She taught an upper division/graduate student elective on pollution prevention in the chemical engineering department at California State University, Long Beach for two years and has co-authored many handbooks, textbooks, and other teaching and outreach materials.
