Career Q&A with Recent Physics Alum Jason Barbier

Can you tell us about your career before coming to the University of Maryland in 2020?

I began my career in 2014 on active duty in the United States Air Force as a full-time radio communications technician at the Royal Air Force Croughton in the United Kingdom. I coordinated communications to the battlefield by maintaining a fixed satellite communication relay station. This involved building a range of skills in electronics repair, network testing and operations management. In 2019, I chose to cross-train to a reserve aircraft maintenance position at the 459th Air Refueling Wing in Joint Base Andrews, Maryland. I inspected, serviced, fueled and launched our fleet of KC-135 refueler aircraft to support long-range missions. 

Serving gave me the opportunity to grow as a professional in several exciting fields. I am immensely thankful for my many family members, mentors, and fellow servicemen and women who encouraged me to pursue my bachelor’s full-time at UMD starting in fall 2020.Barbier in front of 459 ARW Andrews

Why did you decide to study physics at UMD and what do you hope to do with your degree?

Since I was a kid playing with circuit kits and disassembling items around the house, I’ve been drawn to technical fields. When I was working in the military, I found myself pondering deep questions about the nature of reality. As a technician, I spent my time learning how to use the equipment; I wanted to know how and why everything worked. I was curious about everything from quantum particles to the behavior of black holes.

In my travels as a service member, I experienced the world in ways I’d only heard or read about. I saw issues like resource scarcity and environmental degradation everywhere I traveled and decided that I wanted to be part of the solution.

This led me to build an interest in the potential of nuclear fusion power (for energy and space travel). I decided to go into research to move this field forward while learning the intricacies of particles and the current state of reactors. My ultimate goal is to solve energy and environmental challenges with sustainable power sources.

How have you taken advantage of opportunities on campus to pursue your career goals?

First off, from the Terp Vets community, I have found support from other ambitious Terps who transitioned from the military to higher education.

Then in the University Career Center, I made use of essential guidance and career prep resources. After some searching into research projects to join, I found a promising one at the intersection of both CMNS and the Clark School of Engineering. I joined a research team in beam physics at the Institute for Research in Electronics and Applied Physics. Here, I developed my ability to use tools for constructing and testing elements of an electron accelerator. Across the board, I have had so much support from UMD interested in seeing me succeed.

What kind of career guidance and one-on-one feedback did you receive from the University Career Center @ CMNS?

At the Career Center, I spoke with [University Career Center @ CMNS Program Director] Becca Ryan who helped me understand my goals and prepare for internships. In our first meeting, Becca informed me that physics is a degree with many marketable skills, like analysis and research, that can match well to a range of internships and job postings. 

Barbier with PSC in backgroundAfter attending the university’s spring career fair and interviewing with a company of interest, UCC counselors encouraged me by suggesting the skills I would need to succeed and coaching me through the unfamiliar parts of the process such as negotiation. 

As I interviewed, there were questions specific to the industry that I was unsure how to answer. Becca recommended studying material beforehand and asking staff members about the company’s priorities. She also helped me decide what to do with the job offer I received and determine how the job aligned with my goals and career path. Once I made my decision to decline the job offer and pursue graduate studies instead, Becca helped me vocalize it clearly and effectively.

What do you think your next stop after graduation will be (or what do you hope it will be)?

Now that I have graduated with my B.S. in physics, I hope to build upon my physics background and connect to engineering and business to solve needs in the world through products or a startup. I am currently enrolled in the accelerated business master’s program (here at UMD!) to combine my scientific and engineering skills with industry and leadership. It’s a one-year program that will give me the business, financial and communication skills so I can develop technologies that can reach the marketplace.

Next summer, I’ll be looking to gain internship experience this summer and apply for jobs before graduating with my master’s.Barbier with dog

What advice do you have for fellow Science Terps who are looking for internships and jobs?

I am honored by the opportunity to be a Terp and study in such an encouraging and idea-abundant environment! I encourage other Science Terps to speak with the UCC and meet with employers and labs. You never know what skills of yours are in demand until you get yourself out there.


CMNS students have access to career advisors and programs that are personalized to their unique career interests in STEM fields. In this Q&A series, we are spotlighting how Science Terps are capitalizing on the resources, support and guidance that the University Career Center @ CMNS provides.

‘Not Alone’: Mental Health Task Force Analyzes Well-Being of UMD Physics Graduate Students 

Grad school should challenge students’ minds but not their mental health, according to physics graduate students at the University of Maryland who are using scientific principles to understand their peers’ perspectives.

Formed in 2016, the Department of Physics’ Graduate Student Mental Health Task Force (MHTF) is a small, student-led group that conducts surveys to identify the unique challenges faced by physics graduate students. While all of the task force members are researchers, they are also part of the very group they are analyzing.

“When you are studying a population that you yourself are a part of, you come with your own biases, but you also come with an understanding of the group,” said physics graduate student and MHTF member Adam Ehrenberg. “And as somebody who for most of undergrad struggled with their mental health relatively openly, the MHTF seemed like a good way to think about those things in a slightly more official way.”Patrick Banner speaks with colleagues.

The group works together to create surveys and get them approved by the campus Institutional Review Board—a recommended step for research involving human subjects. They then conduct statistical analyses to gather insights, which are condensed into a report and made publicly available online. Some surveys are broadly focused on students’ mental health, while others hone in on a specific issue.

The MHTF’s last report shed light on the high rate of impostor phenomenon among physics graduate students, especially among those who identify as female or nonbinary. People who experience this phenomenon often report feeling like “frauds” who have not earned their spot in a job or academic department. 

Physics graduate student and MHTF member Patrick Banner explained that impostor phenomenon can cause anxiety, depression and low self-esteem, and can even prevent people from pursuing scholarships, fellowships or career opportunities.

“One really harmful aspect of impostor phenomenon is that someone experiencing it may feel that they do not deserve the opportunities they receive and therefore don't pursue them,” Banner said.

Banner said the task force’s next report, slated to publish sometime this semester, will dive deeper into this phenomenon and the role that academic advisors can play in a student’s experience. 


“We had a specific question that we wanted to know, which is: Can the relationship between a student and their advisor affect impostor phenomenon feelings?” Banner said. “We asked not only questions about impostor phenomenon, but also about how students perceived their relationship with their advisor, and we can look at some quantitative correlations between those variables.”

While the MHTF is still analyzing data, preliminary results show that the quality of advising can affect how students view themselves and their place in the physics department. One of the group’s recommendations to advisors is to head off students’ feelings of inadequacy by helping them understand why they might be struggling with a task.

“Grad school is an inherently difficult process to go through, and there are always going to be struggles. Things are going to fail sometimes,” Banner said. “I think the best advisors are good at making that clear and reframing struggles to say, ‘No, it’s not you. This is a hard thing that you’re doing.’”

Steven Rolston, the physics department chair, said the MHTF’s methodical and compassionate approach to mental health has been “gratifying” to witness.

“They address the issue as scientists, using validated tools and raising the levels of statistical analysis as they refine their surveys,” Rolston said. “Simply addressing the topic out in the open—and showing their fellow students that they are not alone and that people do care—can make a big difference.”

The MHTF also produces and manages two resources for grad students: the UMD Physics Grad Student Guide and the Mental Health Resources page on the physics department website. To expand its scope even further, the MHTF started hosting more social events—from movie nights to coffee breaks—to help students feel more connected with their peers. 

In 2021, MHTF members participated in a mental health panel hosted by the American Physical Society and, more recently, shared preliminary results of their newest survey during a meeting of the Chesapeake Section of the American Association of Physics Teachers.

Chandra Turpen, a physics assistant research professor who advises the MHTF, lauded the group’s ability to not only gather data but to effectively share their results with a larger audience.

“This team has consistently done top-notch work—gathering evidence, building relationships with stakeholders across these graduate programs, persuasively communicating their results and making requests to transform our graduate programs,” Turpen said. “Their work embodies many of the best practices for leading inclusive system change efforts.”

Going forward, the group hopes to recruit new students to MHTF—three of the five current members plan to graduate this year. Anyone interested in joining can email the group at This email address is being protected from spambots. You need JavaScript enabled to view it.

And they hope to keep the momentum—and the conversation—going. Erin Sohr (B.S. ’10, physics and astronomy; Ph.D. ’18, physics), who co-founded the MHTF as a graduate student in 2016, said it has been meaningful to see the physics community rally around students’ mental health.

“I think the most important impact is around starting this conversation within the department, normalizing struggles and just making mental health something we notice and talk about together,” said Sohr, who is now a physics assistant research scientist at UMD.

Banner agreed, stressing the value of undertaking these surveys and having difficult conversations.

“Just having the conversation is a way of saying that mental health is a serious issue,” Banner said. “We don’t want to sweep this under the rug. We want everyone to be happy and healthy, so having these conversations is the first step to making that happen.”

Solving the Mystery of the Stinky Vapor Plumes on Campus

Billowing white columns of vapor rise silently from sidewalks and manholes around the University of Maryland campus when it gets chilly. These mysterious plumes are sometimes accompanied by a strange odor or a lingering warmth. Like ghosts, the hazy wisps seem to come and go without much explanation. But what’s the cause of this foggy, strange smelling campuswide phenomenon and where is it coming from? 

“It’s definitely not intentional or desirable,” said UMD Physics Professor Daniel Lathrop. “You’re not supposed to see or smell it at all. In fact, it’s just one component of a much bigger problem. This visible vapor is a sign that our underground utilities infrastructure is aging and inadvertently helping to cause water and heat waste across our campus.”Dan Lathrop.

Like a leaky pipe, this leaking vapor can cause serious problems including infrastructure damage, energy waste and pollution to the natural areas surrounding UMD. 

The university’s infrastructure—some of which dates back over 150 years—naturally deteriorated over time. That includes the decades-old tri-generation energy system that the majority of the campus runs on today.

“Our current energy generation system was installed in 1999. It heats, cools and powers over 250 campus buildings,” explained Lathrop, who also holds joint appointments in the Departments of Geology and Physics, the Institute for Physical Science and Technology, and the Institute for Research in Electronics and Applied Physics. “A natural gas-fired turbine generates most of the electricity we use and the heat that this turbine produces is recaptured to produce steam, which produces additional electric power. The steam is then also used to heat and cool our buildings.” 

Gregg Garbesi, assistant director of utilities and energy management at UMD’s Facilities Management, says the visible vapor comes when liquid (like groundwater, city water leaks, stormwater leaks, etc.) physically contacts the underground steam line. He compares the campus’ visible vapor to steam caused by pouring cold water into a hot pan on a stove. He explains that the odd smells accompanying the vapor occur when organic materials come into contact with the leaked vapor, which is generated underground or in a steam manhole. 

According to Garbesi, seeing these vapor plumes signals energy loss. 

“For every pound of vapor generated, a pound of steam is condensed in the steam pipes,” he said. “All the energy that went into making that pound of steam—which could have been used to power campus—is lost, and if 100% of the condensate doesn’t return to the energy plant, that water is also lost.”

“We’re wasting about a million gallons of water a day now,” Lathrop added. “The loss in 2019 alone is estimated to be 700 million gallons, costing us an estimated $4 to $6 million a year. And that’s just the financial price tag that we know about.”

That’s why Lathrop is leading a multidepartment, cross-disciplinary Grand Challenges team that aims to map and pinpoint locations where steam is being lost and get a better look at challenges with energy consumption, water quality, methane emissions and air quality on UMD’s campus. With colleagues and students from the Departments of Geology, Atmospheric and Oceanic Science, Geographical Sciences, and Environmental Science and Technology, Lathrop hopes to tackle these interrelated issues by pinpointing the biggest problems and providing concrete solutions.

“Methane emissions, carbon dioxide emissions and pipeline water loss from our campus play a big role in stream water and air contamination nearby,” he said. “It’s our goal to measure these impacts and figure out how we can remediate these challenges to reduce our campus’ climate footprint and improve the environment here.”

Diagnosing and treating an aging energy system

When Lathrop began this project in spring 2023, his first step was to work with Facilities Management to learn more about the campus’ utilities-related challenges, particularly the steam issues caused by underground pipelines. He soon realized that his ongoing U.S. National Science Foundation-funded research—to develop sensors capable of detecting geophysical anomalies—could play a key part in this new project. 

“My lab was originally developing geophysical sensors to look for landmines and unexploded ordnance, but we recognized that this same system could be used to find buried utilities,” Lathrop explained, referring to a project that was named a UMD Invention of the Year in May 2022

Credit: Dan LathropUsing these sensors and historic infrastructure blueprints provided by Facilities Management, Lathrop and his team sketched out an extensive map of steam-emitting sources on campus. They concluded that UMD’s energy system had at least 55 active steam vents. 

A group of undergraduate physics majors taking Lathrop’s PHYS 499X class added to those findings when they hand-built a calorimeter (an instrument that measures heat from chemical and physical reactions) in fall 2023 as a course project. 

The students used the calorimeter to identify dozens of campus hot spots and learned that some of these accidental vents lost more than 60 kilowatts of heat energy via escaped condensation. For reference, a standard incandescent light bulb uses about 60 watts of electricity on average—meaning that the steam and heat leaking from some of these vents could power approximately 1,000 of those light bulbs. 

Lathrop estimates that this loss alone could equate to approximately $50,000 per year but he believes that identifying and analyzing the factors that led to the hot spots was invaluable.

“This is a team effort and having everyone on the same page can really make a difference when it comes to fixing things on campus and allocating resources appropriately. Our work has already started to help the university identify and patch sites on campus with water leaks,” he said. “We were able to prevent local building damage and protect students, staff and faculty from potential safety hazards.”

Putting together pieces of a bigger puzzle

Other members of the Grand Challenges project team are also on the ground looking for ways to locate and address the campus’ interconnected water and air quality problems.

Geology graduate student Julia Famiglietti and Geology Chair and Professor James Farquhar tracked gas leaks on campus through the sewer system to create a methane inventory (list of methane sources and sinks). They identified a contamination source underground that they suspect is related to the aging steam system.

“We think that the contamination has something to do with steam additives accidentally coming into contact with and reacting to methane,” explained Famiglietti, who sampled the air in campus sewers at least once a month to determine the composition of gases found in emissions. “We’re focusing on understanding the chemistry behind this contamination signature and directly discussing with the steam plant management personnel how to address the problem.” 

Geology Associate Professor Karen Prestegaard and Professor Sujay Kaushal found similar results while working with student groups to monitor the water quality of streams and storm drains. They discovered that water discharging from steam vents into storm drains had noticeably higher pH values and higher salt contamination than natural rainwater—potentially encrusting pipes with buildup and impacting wildlife in the Paint Branch waterways. 

Other efforts to gather and analyze the researchers’ environmental data include Project Greenhouse, in which First-Year Innovation & Research Experience (FIRE) undergraduates are drafting a sustainable methane budget for UMD.

Lathrop hopes that this multiyear campuswide team effort will help UMD reduce water and steam waste (and the associated environmental and fiscal costs) by 30% by the end of the project in June 2026. He believes this project can serve as a model for other research efforts to analyze similar urban environmental impacts for cities or large organizations like universities. 

“Our campus is a microcosm of urban and suburban environmental impacts, so evaluating UMD’s impact on the environment leads to a better understanding of how humans impact climate on a local, national and global level,” Lathrop said. “We’re all doing our part to protect our campus and the people living and working here.”
