Alex Hansen stepped foot in a landfill this summer for the first time to study the consequences of methane emissions. What he saw sparked a growing interest in climate change research and environmental data analysis.

Hansen, a rising senior in the Paul M. Rady Department of Mechanical Engineering, spent his summer break in ��’s Summer Program for Undergraduate Research (SPUR).

The program aims to increase undergraduate research engagement and interest by pairing nearly 125 engineering students from across the college in research labs with faculty members and graduate mentors. For 10 weeks, students foster unique, hands-on research experiences—like a trip to a landfill in Los Angeles—and develop crucial skills that serve them well beyond their undergraduate journey.

For Hansen, it was a special curiosity that led him to the SPUR program. One that started from a simple conversation.

“I spoke with someone I ran into one day a while back who worked at a landfill. He was telling me how dangerous methane is and how important it is to burn off methane,” said Hansen. “I was just so fascinated by it all. When I saw the project description on the SPUR website, I knew it was something I wanted to learn more about.”

And dangerous is an understatement. Methane, one of Earth’s most potent greenhouse gases, is one of the primary contributors to climate change. Its atmospheric lifespan may be shorter than other greenhouse gases like carbon dioxide, but it can trap significantly more heat per molecule, making it extremely hazardous to human and environmental health.

According to the UN Environment Programme, methane is 80 times more potent at warming than carbon dioxide over a 20-year period. It’s also responsible for nearly 30% of global warming since pre-industrial times and is a key culprit for the formation of ground-level ozone, which causes one million premature deaths every year.

It’s a spiraling issue, but Hansen says his SPUR project titled “Characterizing Landfill Methane through a Low-Cost Ground-Based Sensor Network,” looks to attack the crisis by addressing some of the world’s most prevalent methane emissions sites.

“Landfills are one of the largest emitters of methane in the United States,” Hansen said. “I believe waste is about third for methane emissions across the entire world. If we are able to study a landfill and learn more about the way methane spreads in the atmosphere, maybe we can find a way to make improvements to landfill infrastructure and lower emissions.”

To do this, Hansen and his lab mates in Professor Michael Hannigan’s Hannigan Air Quality and Technology Research Lab started working with a network of 24 low-cost air quality sensors called L-Pods that were deployed across a landfill in Los Angeles at the beginning of 2025.

The L-Pods are equipped with two metal oxide sensors that collect air pollutant data and another sensor that tracks temperature and relative humidity. The data is then stored locally and transmitted to the cloud every 10 seconds for ongoing monitoring.

These unique sensors may not be as individually powerful as the industry-grade technology used by the Environmental Protection Agency (EPA), but they are cheap and efficient. This allows the group the ability to position more sensors across a landfill than they previously could, giving them a precise methane reading that represents a much larger region.

Hansen spent a majority of his summer SPUR experience helping the team analyze the data gathered from the sensors. But he was able to see the sensors in action firsthand at the Los Angeles landfill where they are deployed.

It was crazy seeing how much trash we make and the operations needed to contain it all,” said Hansen. “And these low-cost sensors were awesome to see, too. We can add so many more positions and measure way more often than traditional measuring devices. It’s super exciting to see the data we collect in real-time and how impactful it is.”

Hansen’s journey through the SPUR program ended with a final presentation at the end of July. It was a chance for him to share his learning and reflect on his summer.

In many ways, he said it was a rollercoaster ride filled with highs and lows. Some seasoned researchers might call that the typical research experience.

But Hansen also said it was valuable and fulfilling. So much so, that he might be eyeing a future career in research.

“Being in the lab was definitely a learning curve at first. Just learning the terminology and trying to get up to speed as quickly as possible was tough,” Hansen said. “But there’s so many opportunities to make a big impact in research. I’ve learned so much from amazing people this summer and I am definitely curious about pursuing research in a master’s program after graduation.”

Rising senior Alex Hansen spent his summer break in ��’s Summer Program for Undergraduate Research (SPUR) studying the consequences of methane emissions. His work analyzing data gathered from unique methane detection sensors can one day help researchers address the methane crisis at some of the world's most prevalent methane emissions sites.

Robots and chemistry isn’t just a fun combo. Bruns says it’s the future

Robots and chemistry isn’t just a fun combo. Bruns says it’s the future Alexander Jame… Fri, 06/06/2025 - 16:02

Carson Bruns is working to lend chemists a hand—literally—by bringing collaborative robots into chemical wet labs.

Bruns, an assistant professor in the Paul M. Rady Department of Mechanical Engineering at ��, is leading the charge on a project that he and his team like to call “robochemistry.” Their goal is to create robotic sidekicks that can assist chemists with burdensome or unsafe tasks that they may encounter in a wet lab on a daily basis.

According to the U.S. Bureau of Labor Statistics, chemists and materials scientists held nearly 100,000 jobs in 2023 and overall employment is expected to grow eight percent over the next 10 years.

But unlike other large and growing industries, Bruns says chemical research and development has remained devoid of robots, often leading to injuries and considerable risks in the workplace.

“There are a lot of potential benefits for introducing robots into a chemical lab that haven’t been explored yet,” said Bruns, who is also affiliated with the ATLAS Institute, Biomedical Engineering Program and Materials Science and Engineering Program. “Our angle involves trying to reduce work burdens and safety risks, develop robots that collaborate with humans instead of replacing them, and increase accessibility so that even people with disabilities can perform chemistry.”

Middle school students exploring the intersections of robotics and chemistry during one of the "robochemistry" interactive workshops led by Bruns and his team.

The project, funded by the National Science Foundation, is in collaboration with researchers from the University of North Carolina at Chapel Hill and ��’s Department of Computer Science. It started with an extensive observation-based task analysis that allowed Bruns and his team in the Emergent Nanomaterials Lab to develop a strong understanding of the various tasks that chemists were performing regularly in a wet lab.

After observing, interviewing and surveying their chemist test subjects, Bruns and his group were able to identify an array of different tasks that can potentially benefit from human and robot collaboration.

“We learned right away that chemists don’t really like doing a purification task called dialysis that is very common in a wet lab. It’s repetitive, it takes a lot of time and sometimes chemists have to come back to the lab in the middle of the night to change dialysis bags, which they don’t want to do.” Bruns said. “It seemed like a great case for a robot, so we built a robotic system automating the dialysis process.”

Bruns says his team of researchers has a list of other potential benefit areas, as well, including simple tasks like stabilizing a flask or offering a third hand to hold something for chemists when they need it. They are even trying to find solutions for more complex safety issues so that chemists can stay far away from violent and dangerous reactions.

But that’s not where the project ends. There is also an outreach portion aimed at improving science education and enhancing youth interest in science.

Led by PhD student Diane Jung, Bruns and his team ran a four-day interactive workshop series at a local middle school in Boulder. These workshops invited middle school students to build robots with Legos and use them to perform various chemistry experiments—something that’s already happening in Bruns’ lab.

“We’ve been building ordinary automation tools out of Lego because it’s cheaper and reconfigurable. When you don’t need it anymore, you just disassemble it and build it into something else,” said Bruns. “So we thought we could use this Lego thing we had going on in our lab already to appeal to a younger audience and show kids the fun and evolving intersection between chemistry and robotics in real time.”

During the workshop series, Bruns noticed various groups of students approaching experiments with unique perspectives and ideas. He said it was inspiring to see young kids actively engage with the science in front of them.

But most importantly, he saw the kids have fun.

“Thinking back to young Carson when he was a kid—it always just seemed very fun to me,” Bruns said. “I had positive role models in my life who also believed science was fun, so that was our goal with this part of the project. To help kids have a more positive association with the idea of science and engineering.”

Assistant Professor Carson Bruns is leading the charge on an NSF-funded project that he and his team like to call "robochemistry." Their goal is to create robotic sidekicks that can assist chemists with burdensome or unsafe tasks that they may routinely encounter in a wet lab. But that's not all: this unique blend of bots and beakers can also inspire youth interest in science.
