First-year MIT students gain hands-on research experience in supportive peer community

New Post has been published on https://thedigitalinsider.com/first-year-mit-students-gain-hands-on-research-experience-in-supportive-peer-community/

First-year MIT students gain hands-on research experience in supportive peer community

During MIT’s Independent Activities Period (IAP) this January, first-year students interested in civil and environmental engineering (CEE) participated in a four-week undergraduate research opportunities program known as the mini-UROP (1.097). The six-unit subject pairs first-year students with a CEE graduate student or postdoc mentor, providing them with an inside look at the interdisciplinary research being conducted in the department. Overall, eight labs in the department opened their doors to the 2024 cohort, who were eager to take advantage of the opportunity to collaborate with current students and build a community around their interests.

“The mini-UROP presents an opportunity for first-year students to experience the diverse climate and sustainability research happening in our department,” says CEE department head and JR East Professor Ali Jadbabaie. “Fostering hands-on experiences in a collaborative, supportive educational environment is central to our mission of preparing students with the skills needed to positively shape the future of our society, systems, and planet.���

The mini-UROP also benefits the graduate students and postdocs who take on the role of mentor. Mentor support is a key component to completing a successful mini-UROP project and requires graduate students and postdocs to hone their leadership and teaching skills.

“I’m always interested in mentoring undergraduate students and to have someone help me with my project,” says postdoc and mentor Yue Hu. “Participating in this project made me excited that my research attracted undergraduates’ interest.”

Guiding students through interactive workshops

Preparation for this year’s mini-UROP began at the end of November, when participants attended the Lightning Lectures, an event that served as an opportunity for the mentors to give lightning-fast pitches on their research projects. First-year students then ranked the projects that they were interested in working on and were matched according to their preferences.

The interdisciplinary nature of the department’s research offered participants a wide range of projects to work on, from redefining autonomous vehicle deployment to mitigating the effects of drought on crops. Once each of the 11 participants were matched to a project, the mini-UROP Kick-off Lunch brought students and mentors together and ensured each group had an open line of communication.

Throughout the duration of the mini-UROP, participants attended three workshops led by Jared Berezin, the manager of the Civil and Environmental Engineering Communication Lab (CEE Comm Lab). The communication lab is a free resource to undergraduates, graduates, and postdocs in the CEE community, providing one-on-one coaching and interactive workshops. Held on Fridays during IAP, the workshops helped students contextualize their research and ensure they were able to explain the scientific concept of their work during presentations.

“Students were fortunate to have research mentors in the lab, and my goal was to provide communication mentorship outside of the lab,” says Berezin. “Our weekly workshops focused on scientific communication strategies, but perhaps more importantly I’d prompt them to talk about their projects, ask questions, and brainstorm together. They really embraced the opportunity to foster a supportive peer community, which I think is a core part of the CEE experience.”

A significant challenge students face while completing the program is condensing their research down to a clear and concise two-minute presentation. To assist with this task, the third workshop featured a presentation by CEE Comm Lab fellow Matthew Goss, providing students with a preview of how their own presentations may take shape. Students also had the option to meet with Comm Lab fellows to practice presenting and get feedback.

“The final talks were impressive, and I was proud of the students for approaching both their research and communication challenges with such curiosity and thoughtfulness,” Berezin remarks.

Reinforcing research interests

Iraira Rivera Rojas, a first-year student interested in materials science and environmental engineering, worked with Yue Hu, a postdoc in Associate Professor Benedetto Marelli’s lab. Their project used biodegradable polymers, specifically silk fibroin, to make particles that can be used to encapsulate agrochemicals, lessening their negative impact on the environment. Regenerated from silk cocoons, the silk fibroins are used as a building block to revolutionize the agriculture and food industry.

“When I saw the project description, it was a mix of both of my interests,” Rojas says. “I thought it would be a good way to try out both fields.” While she is still deciding which course she will major in, she says that participating in the mini-UROP confirmed her interest in the field.

Working with mentor Jie Yun, a graduate student in Associate Professor David Des Marais’s lab, Sheila Nguyen and Ved Ganesh used biodiversity to increase crop drought resistance. Nguyen and Ganesh studied barely, oat, wheat, and Brachypodium, and compared how these plants grow under conditions of drought stress. Currently, a separate model must be trained for each plant species and type of cell. The project aimed to develop a machine learning model that can generalize to different species of plants and cell types.

Vinn Nguyen and Diego Del Rio worked with mentor Cameron Hickert, a graduate student in Assistant Professor Cathy Wu’s Lab. Their project focused on making autonomous vehicles safer and more reliable, specifically in areas transitioning on and off highways. As self-driving cars gain popularity, reports of crashes and similar incidents demonstrate deficiencies in the current system. Nguyen and Del Rio sourced satellite imagery and applied computer vision techniques to investigate the safeness of these areas. The goal of their project was to design an infrastructure-supported approach to autonomous vehicles that allows passenger to comfortably work, play, and connect with partial autonomy.

Jordyn Goldson worked in the Terrer Lab with her mentor Kathryn Wheeler, a graduate student in Assistant Professor Cesar Terrer’s lab, on a project focused on plant senescence. As warmer temperatures lengthen plants’ growing period each year, total annual photosynthesis increases along with the amount of carbon plants remove from the atmosphere. Her project investigated if model performance differs between predicting visually assessed timing versus remotely sensed timing. The findings can help advance knowledge of the mechanisms behind forest canopy color change and the ability of forests to capture more carbon by growing longer, mitigating climate change.

Based on the success of her mini-UROP project, Mairin O’Shaughnessy, who worked in Professor Heidi Nepf’s lab with graduate student Ernie Lee, will be continuing her research on “Computer Vision for Plant Density Analysis” in the spring.

“When Heidi and Ernie, the grad student advisor for the project, proposed continuing the project in spring, I was interested in continuing to learn more and explore vision processing for counting real plants,” O’Shaughnessy says.

Jennifer Espinoza, another student who worked in the Nepf Lab, plans to continue her research with graduate student James Brice on “Characterizing Flow Conditions.”

“One of the main things I loved most about working in the lab was the passion that my mentor, James, portrayed for his work, as well as his willingness to teach me anything without complaint,” says Espinoza. “Most of all, though, I became extremely passionate about my work because it has the potential to make an impact in not only society but the natural environment. The significance of my work and the welcoming working environment have prompted me to continue researching at Nepf Lab in the spring.”

The History of 3D Pringting

The concept of additive manufacturing has existed since the 1940s. In 1945, sci-fi author Murray Leinster described a machine that could “make drawings in the air” and output plastic parts layer-by-layer in his short story “A Logic Named Joe.” However, it took a few more decades for this vision to become reality.

1980s: Early Prototyping

In 1981, Dr. Hideo Kodama of Nagoya Municipal Industrial Research Institute invented one of the first working rapid prototyping systems. It used photopolymers that could be cured by UV light to build parts additively.

In 1984, Charles “Chuck” Hull filed a patent for stereolithography (SLA), which described an additive manufacturing process using photopolymers cured layer-by-layer by UV lasers. He later co-founded the company 3D Systems to commercialize SLA 3D printers.

In 1986, Carl Deckard, an undergraduate at the University of Texas, filed a patent for selective laser sintering (SLS), another 3D printing process that used a laser to fuse powder material. Deckard’s patent was licensed by DTM corporation, which released the Sinterstation 2000, the first SLS machine, in 1992.

In 1989, S. Scott Crump invented fused deposition modeling (FDM) and patented the technology. This process used a heated nozzle to extrude thermoplastic filament material layer by layer. Crump later commercialized it through the company Stratasys, which he co-founded.

1990s: Industry Growth

In 1992, 3D Systems released the SLA-250, which was the first commercially available 3D printer. Meanwhile, Stratasys introduced their first commercial FDM 3D printer in 1992 as well.

Through the 1990s and 2000s, the industry saw rising adoption and usage of additive manufacturing for rapid prototyping across automotive, aerospace, medical, consumer goods and other industries. Both established corporations and startups expanded the capabilities of 3D printing during this period.

2000s: Patent Expiration, Desktop 3D Printers

A significant milestone came in 2009 when key SLA patents expired, opening up the technology. This allowed for the rise of desktop SLA 3D printers like the Form 1, developed by startup Formlabs in 2012.

The expiration of FDM patents around 2010 similarly saw a wave of open source FDM/FFF desktop 3D printers like the RepRap, inspiring companies like MakerBot. This drove increased adoption of desktop 3D printing.

The Basics of 3D Printing: How it Works and its Advantages

The process of 3D printing involves several steps. First, a digital design of the object is created using computer-aided design (CAD) software. This design is then converted into a format that can be read by the 3D printer. The printer then builds the object layer by layer using various materials such as plastic, metal, or even biological materials.

One of the key advantages of 3D printing is its ability to create complex geometries that are difficult or impossible to achieve with traditional manufacturing methods. Traditional methods often involve subtractive processes, where material is removed from a larger block to create the desired shape. In contrast, 3D printing is an additive process, where material is added layer by layer to create the final object.

Another advantage of 3D printing is its ability to create customized products. With traditional manufacturing methods, producing customized products can be expensive and time-consuming. However, with 3D printing, each object can be easily customized by simply modifying the digital design before printing.

From Prototyping to Production: How 3D Printing is Changing the Manufacturing Process

One of the key roles of 3D printing in manufacturing is in the prototyping stage. Traditionally, prototyping involved creating molds or tooling, which can be expensive and time-consuming. With 3D printing, prototypes can be created quickly and cost-effectively, allowing for faster iteration and refinement of designs.

However, 3D printing is not limited to prototyping alone. It has the potential to replace traditional manufacturing methods in certain applications. For example, in industries such as aerospace and automotive, where complex geometries are often required, 3D printing can offer significant advantages over traditional methods. By eliminating the need for molds or tooling, 3D printing can reduce costs and lead times while enabling the production of lightweight and optimized components.

Customization and Personalization: The Power of 3D Printing in Meeting Customer Demands

One of the key advantages of 3D printing is its ability to create customized products. Traditional manufacturing methods often involve producing large quantities of identical products, which may not meet the specific needs or preferences of individual customers. With 3D printing, each product can be easily customized to meet the unique requirements of each customer.

This ability to create customized products has a significant impact on the customer experience. Customers today are increasingly looking for personalized products that reflect their individual tastes and preferences. By offering customized products, companies can differentiate themselves from their competitors and build stronger relationships with their customers.

Reducing Costs and Waste: The Economic Benefits of 3D Printing in Manufacturing

One of the key advantages of 3D printing is its potential to reduce manufacturing costs. Traditional manufacturing methods often involve multiple steps and processes, each adding to the overall cost of production. In contrast, 3D printing simplifies the manufacturing process by directly creating objects from a digital design, eliminating the need for molds or tooling.

By reducing the number of steps and processes involved in manufacturing, 3D printing can significantly reduce costs. This is particularly beneficial for small and medium-sized enterprises (SMEs) that may not have the resources to invest in expensive molds or tooling. With 3D printing, SMEs can compete with larger companies by offering customized products at a lower cost.

In addition to reducing costs, 3D printing also has the potential to reduce waste. Traditional manufacturing methods often result in significant material waste, as excess material is removed during the production process. With 3D printing, only the required amount of material is used, minimizing waste and reducing environmental impact.

Sustainability and Environmental Impact: How 3D Printing is Helping to Reduce Carbon Footprint

In addition to reducing waste, 3D printing also has the potential to reduce carbon footprint. Traditional manufacturing methods often involve transporting raw materials and finished products over long distances, resulting in significant carbon emissions.
