Margaret Carreiro, PhD

Margaret Carreiro earned her PhD in Botany from Univ. of Rhode Island.  She taught in UofL’s Biology Dept. from 2001 until retiring in 2018.  Her research focused on plants and decomposer organisms, including their responses to fossil-fuels combustion and invasive species.  Her Ecology courses included climate change, its causes, impacts and solutions.  Dr. Carreiro wrote the Urban Forestry section of the Louisville's Climate Change Action Task Force's 2008 report to the mayor, and the Louisville Tree Board's guidelines for the first local tree-canopy assessment and its urban forest-management program.  She contributes to LCAN's Facebook page.

Agastya Mishra,
Student Intern

Agastya Mishra is an 9th grader at Manual High School.  After reading about climate change and realizing his generation's future is at stake, he decided to make a positive difference.  Luckily, his research led him to LCAN.  He helps to stock the virtual shelves of our Kids' Books and Videos web page.  Last school year, he led his Meyzeek classmates in creating an ecology-themed quick-recall package; they beta-tested it and now are refining it for use by other schools.  He also enjoys computers, sports, music, hanging out with his friends and "building stuff."

Roger Ohlman,
Energy Analyst

After 43 years in the banking industry, Roger felt called to focus on climate and anti-racism initiatives.  He recently received a Kilowatt Crackdown award for his work with the Louisville Nature Center (LNC), where he first found ways to lower its utility bills, then assisted with installing solar panels, resulting in LNC achieving net-zero status!  With a small team of church members, he now helps First Unitarian Church in similar ways.  For LCAN, Roger analyzes clients’ energy usage to find ways to improve efficiency and lower costs.​
