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.

Emmeline Meldrum,
Pre-Engineering Intern

Emmeline Meldrum is an incoming freshman at the University of Michigan, where she will study Environmental Engineering.  She enjoys knitting, spending time outdoors and playing the guitar.  She became passionate about the environment in middle school, and her concern grew as she saw the pollution on the Ohio River, where she rowed with her crew team. Emi and Maddox (next) are assisting LCAN with environmental audits and many other projects intended to introduce them to the engineering profession. 

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.​

Maddox Miller,
Pre-Engineering Intern

Maddox Miller just finished her second year at Colgate University, double majoring in physics and environmental biology.  She will be transferring to an engineering school to earn a PhD in environmental engineering.  Her love for the planet was cultivated from a young age by her grandmother, who taught her the importance of caring for wildlife, expanding tree canopies and tending a garden of native wildflowers. Today, she runs in area parks, attends community events with friends and reminisces about her research trips to Alaska!  Maddox is excited to be interning at LCAN this summer, especially assisting with energy audits.

Rachel Mudd

Rachel Mudd earned her bachelor's degree in Sustainability with a minor in Communications and a focus on social justice from the University of Louisville in 2024.  She now serves as an enforcement officer for the Metro Louisville Air Pollution Control District.  She enjoys spending quality time in nature, swimming and bike riding.  She remembers learning about climate change and global warming in middle school, and became especially interested after choosing her major at UofL.  Rachel continues to volunteer with LCAN, managing our Instagram, and tabling at events.

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."
