I am located in Castle Rock, CO, and am willing to travel between Colorado Springs and Denver for teaching. My fields of expertise are environmental science, microbiology and global change. I am also qualified to teach introductory biology and Earth science.

I began teaching biology, genetics, and ecology to undergraduates while completing my graduate degree in microbial ecology. After completion of my degree and working briefly in the alternative energy industry, I chose to move to Costa Rica to train and work as a naturalist. While there, I became a tour guide specializing in amphibians and reptiles. I also began teaching Earth science and environmental science at the secondary school level. I moved back to the United States in 2011 and began teaching microbiology and psychology at the college level, and then food microbiology and environmental science at Johnson and Wales University.

Throughout the past decade I have written and published hundreds of articles in environmental science and global change both online and in print.

I hope to work with students to share my passion for learning and help advance you in your goals.
