NSF REU Site: Interdisciplinary Research on Plastic Pollution

The University of Missouri is excited to offer a new National Science Foundation (NSF)-funded Research Experiences for Undergraduates (REU) Site focused on Interdisciplinary Research on Plastic Pollution!

This nine-week summer research program will provide 10 undergraduate students with hands-on research experiences addressing one of today's most pressing environmental challenges. Working closely with faculty mentors from multiple disciplines, students will explore innovative approaches to understanding plastic pollution, including microplastic generation, detection, characterization, environmental fate, and sustainable solutions. Participants will gain experience with advanced analytical techniques, experimental research, and data analysis while developing valuable scientific communication and professional skills through workshops, seminars, and research presentations.

The program aims to inspire and prepare the next generation of scientists and engineers to tackle environmental challenges through interdisciplinary research.

Research Projects for Summer 2027

Improved quantification of MPs using Machine Learning

This project focuses on enhancing microplastics identification and quantification by integrating µ-Fourier Transform Infrared Spectroscopy (µ-FTIR) with machine learning. Current methods often lack sensitivity and scalability, and this work aims to improve accuracy by automating the analysis of spectral data. The project is led by Dr. Ali Shiri from Electrical Engineering and Computer Science Department.

Improved Extraction of Micro and Nanoplastics Using Hydrophobic Deep Eutectic Solvents

This project addresses a major challenge in MNP research, the limited effectiveness of conventional extraction methods in isolating plastics from complex aqueous environments using hydrophobic deep eutectic solvents (HDESs). The project is led by Dr. Gary Baker from Chemistry Department.

MP Analysis Using Pyrolysis Gas Chromatography-Mass Spectrometry

This project focuses on the use of Py-GC/MS for the quantification of MPs in environmental samples. Unlike traditional particle-counting methods, Py-GC/MS provides a significant advantage by enabling mass-based quantification of MPs, offering deeper insight into environmental plastic loads, and does not have a size limitation for plastic particles. The project is led by Dr. Maryam Salehi from Civil and Environmental Engineering Department.

Quantification and Characterization of MPs in Wastewater by UPLC-MS/MS

In this project, REU students will contribute to the development and application of an Ultra Performance Liquid Chromatography coupled with Tandem Mass Spectrometry (UPLC-MS/MS) method to detect and characterize MPs in wastewater by targeting their depolymerized monomer units. The project is led by Dr. Chung-Ho Lin from SNR.

Studying MPs Release from Controlled-Release Fertilizers

Increasing application of plastic products is concerning food safety due to their MP release potential. This project will examine the early phase of MPs release from controlled-release fertilizers (CRFs). The project is led by Dr. Reid Smeda from SNR.

Investigating Fluid Dynamics in the MPs Transport System

Understanding fluid dynamics is essential for predicting how MPs move through aquatic environments. This project introduces students to the fundamental principles of MP transport in turbulent flows and provides hands-on training in experimental fluid mechanics. The project is led by Dr. Binbin Wang from Civil and Environmental Engineering Department.

Developing a Drag Model to Determine Rising/Settling Velocities of MPs

Numerical simulation plays a vital role in understanding how particles move through fluid systems, particularly in the context of MPs and their environmental impact. This project trains students in the fundamentals of numerical methods by guiding them through the development of a drag model to estimate particle rising and settling velocities. The project is led by Dr. Binbin Wang from Civil and Environmental Engineering Department.

Synthesis of Biodegradable Plastics Using PHA Biosynthesis

Replacing synthetic plastics with biodegradable alternatives is critically important to address the global plastic pollution crisis. This project explores the microbial production of biodegradable plastics as a sustainable alternative to petroleum-based materials. The project is led by Dr. Wan from Chemical and Biomedical Department.

Investigating Organic Leaching from Rubber-Modified Asphalt

This project explores the environmental implications of using recycled rubber in asphalt mixtures. Students will begin by learning about the design and use of rubber-modified asphalt and the sustainability benefits and challenges it presents. The project is led by Dr. Baolin Deng from Civil and Environmental Engineering Department.
