Who is Dr. Microplastics?
I am Derek Ho, PhD in Biological Systems Engineering from UW-Madison, and I currently working at the University of Pennsylvania and the Academy of Natural Science - Drexel, as a researcher studying microplastics.
As Dr. Microplastic, I am dedicated to studying the presence, transformation, and impact of microplastics in air, water, and soil. My research focuses on understanding how plastics degrade over time, how they interact with environmental factors, and how we can improve detection methods to better assess their distribution and risks. By employing advanced analytical techniques, such as fluorescence imaging and spectroscopy, I work to uncover the hidden pathways of microplastic pollution and develop solutions for more effective monitoring and mitigation.
Beyond the lab, I take a hands-on approach to tackling plastic pollution through Philly Plastic Pals, a community-driven initiative I lead in Philadelphia. Our mission is simple: conduct regular trash cleanups to remove plastic waste from the environment while surveying the types of litter that may eventually degrade into microplastics. By analyzing the composition and sources of discarded plastics, we aim to connect local pollution trends with broader environmental concerns, bridging the gap between scientific research and community action.
In addition to my field and lab work, I am deeply committed to educating the next generation about the critical issue of plastic pollution. I developed the Plastic Panic! curriculum, a series of 23 educational units disseminated across the Great Lakes states, designed to raise awareness about microplastics and their impact on the environment. This curriculum provides students with hands-on activities, scientific insights, and a deeper understanding of the challenges surrounding plastic pollution in Wastewater treatment plants, and their presence in the environment.
Furthering my outreach efforts, I have also collaborated with South Carolina Sea Grant to create an interactive card game aimed at teaching the "7 Rs of Renewability." (Refuse, Reduce, Reuse, Repair, Recycle, Rot, Rethink). The game engages participants in learning about sustainability through play, making complex environmental concepts more accessible and fun. This project, alongside the Plastic Panic! curriculum, allows me to merge my passion for science and education to foster a broader understanding of the microplastics crisis and encourage proactive environmental stewardship.
Through both research and advocacy, I strive to raise awareness about plastic pollution and work toward tangible solutions that protect ecosystems and public health. Whether in the field, in the lab, in classrooms, or alongside community
