This project will utilize a large number of data sources, including transportation data, climatic data, extreme event (e.g., flooding, hurricane, etc.) observations, environmental records (e.g. areas, water depth of flooding), and land use characteristics, to comprehensively evaluate the magnitude of impacts from climate change on human mobility. The study-focused areas include Philadelphia, PA (for urban flooding analyses), Louisiana/Texas (where hurricanes are more frequent), and Nigeria (for rural flooding analyses). The outcomes of the project are statistical models and/or AI/Machine Learning models that analyze and predict short-term/long-term influence of climatic events, as a result of climate change, on human mobility and its indication on quality of life.
The Match student will be paired with a postdoc/PhD student to first comprehensively understand available data sources and then complete one analysis for a selected climatic event using example datasets.

Many recent publications have shown that microplastic particles (MPs) (1-繕m to 5-mm) are ubiquitous in the environment, found in the most remote locations of the globe as well as in the human body. This has caused concern about potential resulting health effects, especially because MPs may have other associated pollutants attached to them, including trace metals and endocrine disrupting chemicals (EDCs). This makes accurate quantification and characterization (what type of plastic) of MPs in the environment, as well as better understanding of their fate and transport, immensely important. One critical area of research for MPs is urban stormwater runoff. Anthropogenically-produced, MPs emanating from urban areas mix into stormwater during rain events and then may enter green stormwater infrastructure (GSI) systems, which have a goal of removing pollutants. However, it is yet unknown how well GSI can remove MPs. For this project, the top layer of several GSI systems will be collected and MPs will be extracted from different depths to determine the number, size, morphology, and characterization of MP particles with depth of GSI media to estimate the historical removal of MP particles. Additional water and/or air deposition samples may also be collected to contextualize the media results.
The student will use a visual stereomicroscope and additional micro-specimen tools to carefully count and categorize extracted MP particles that are collected on a filter. Images of the filter and/or individual particles will also be taken, and microscope software tools will be used to measure particle dimensions. Data will be collected via handwritten notes and/or in Microsoft Excel with specified organizational structures. The student must be able to conduct meticulous, repetitive work that requires high levels of precision, patience, and attention to detail.

Additive manufacturing has revolutionized our ability to produce prototypes and functional engineering parts. The primary advantage to additive manufacturing is its ability to create specialized geometries previously inaccessible by traditional subtractive manufacturing. While the technology has found widespread consumer adoption for decorative and functional items, it has also begun to permeate the industrial sector. For example, metal additive manufacturing has already found its way into rockets, aircraft, and automobiles. However, when it comes to academic and industrial research, the potential of additive manufacturing has not been fully realized.
Experimental research has historically been limited by access to expensive testing equipment. With the recent revolution of additive manufacturing, anybody can make high-performance parts affordably. While 3D-printed components can be found in many laboratories across the world, there is no repository of designs for research equipment or consolidated information about the research-relevant properties of commercially available 3D-printer filaments.
This project aims to lay the foundation for a 3D-lab, an affordable, versatile laboratory accessible to anyone with fundamental knowledge in engineering and a passion for discovery. By driving down the cost of equipment, we can increase research accessibility to more brilliant minds around the world.
The first stage of the project consists of constructing and tuning a fused filament 3D-printer capable of printing engineering-grade components. The first stage also consists of documenting research-relevant properties for commercially available polymer filament. All processes and testing will be documented and made available online through open-source repositories.
In coordination with the advisor, the match student will be responsible for two primary tasks. The first task will be to construct, tune, and calibrate a Voron 0.2 3D-printer using publicly available tutorials and guides. The student will also document the build process. The student will be expected to ensure adequate print quality at reasonable speeds for PLA components. If time allows, the student may also explore the emission of VOCs and particulates from the printer and develop mitigation strategies, such as filters or ventilation.
The second task is to document relevant properties of commercially available filaments, such as ASA, Polycarbonate, carbon-fiber reinforced nylon, and others. Examples of relevant properties include tensile strength, heat resistance, and chemical resistance. At least two sets or printing parameters will be explored, including a lightweight parameter set which emphasizes low weight for components where structural loads are low, and a heavyweight parameter where structural strength is critical for the functioning of the component. The student will document relevant properties and share the results in an online repository.
