When preparing for college, prospective students and parents often ask about career readiness. How is the university preparing its students for the workforce? What’s the rate of job placement? Do the students succeed in their respective careers?

��AV has a strong track record of preparing students for careers. And the Honors College is working to make sure Honors students are ready to shine in a competitive job market.

“These are incredibly motivated students. I am beyond impressed with their enthusiasm and intellect. And they’re ready. They have all the tools to succeed in the workforce, they just need the knowledge of how to find the right opportunity,” said Jeff Shen.

Shen, who graduated from what was then known as the Presidential Scholars Program in 1996 with a degree in decision sciences, is president of Red Team Consulting and a member of the Honors College Advisory Board. Last year, he came to Dean Zofia Burr with an idea for how to prepare Honors College students for their careers: a roundtable for students to meet with professionals in government contracting, supported by the Greg and Camille Baroni Center for Government Contracting.

“I spoke with some students during graduation,” Shen said, “and in asking them about their post-graduation plans and job opportunities, I realized that these really bright and promising students were missing some of the foundations for approaching the job market: how to network, where to look for opportunities, and so on. So I thought, there must be some way we can address that gap.”

The idea for the roundtable coincided with plans to develop the Honors College Professional Development Fellows program. As part of the program, the roundtable was one of a series of workshops that help students in the program craft their resumes, build their LinkedIn profiles, practice interviewing, and otherwise prepare for internship and career opportunities.

The first roundtable event in Spring 2024 featured 12 George Mason alumni, all of whom are major executives at government contracting companies. The first was such a success that Shen and the Honors College decided to host a second event in Fall 2024.

“In government contracting, you can be a writer, a clinical researcher, a health care professional, you can be in sales: It does not matter the background, there’s going to be a position in government contracting for that person,” Shen said. “I wanted students to see the world of possibilities in terms of what they could do with their degrees.”

Students had the opportunity to speak with each executive in small groups, gaining valuable insights and advice on how to prepare for their career.

Jessica Taylor, studying music technology with a minor in computer science, was one of the fellows in the spring. “As a music major who wants to go into software engineering, I have an untraditional background that needs to be particularly explained and presented when I’m introducing myself to potential employers,” she said. “The fellows program taught me that my variety of creative experience is actually one of the things that makes me stand out.”

“We received [the mentors’] personal emails, offering the opportunity to follow up on potential career opportunities and further discussions,” said Monica Amaya, a management information systems major with a minor in computational and data sciences. Amaya attended the roundtable in Fall 2024. “The entirety of the Professional Development Fellows program has given us valuable networking opportunities to build meaningful relationships with successful government contracting leaders in the area.”

“I learned a lot about what it takes to build a business,” said cyber security engineering student Cameron Portis. “Hearing some of the stories about how these leaders overcame difficulties and changed their plans really inspired me to keep pushing toward my goals no matter what.”

The program continues to grow. In Spring 2025, the roundtable opportunities will expand to two new fields: Health administration and leadership, organized by Inova Health System’s Loren Rufino, BS Health Services ’12, and arts/performing arts nonprofit leadership, organized by Deb Gandy. Both are members of the Honors College Advisory Board.

And for Shen, opening doors for students is only part of the mission. “This is a great way for alumni and community members to get involved with George Mason,” he said. “I’m hoping this opens the door for them as well."

Research using AI to track Amazon rainforest species produces landmark results

Research using AI to track Amazon rainforest species produces landmark results Colleen Rich Mon, 11/25/2024 - 08:47

Thanks to the tenacity of a ��AV biology professor, animals in the Amazon have a lot less privacy these days, but that’s good for scientists who to want know what’s going on in the Brazilian rainforests.

David Luther recognizes the importance of playing the long game in research, but even he couldn’t have imagined the hurdles and roadblocks ahead of him following the approval of his 2019 4-VA Collaborative Research Grant proposal, “Species richness resilience to habitat fragmentation and restoration in tropical rainforests.”

His plan was to install recording equipment at 50 sites as part of the Biological Dynamics of Forest Fragments Project (BDFFP) in the Amazon rainforest of Brazil. These audio and video devices were meant to document and measure differences in animal community composition and the rate of animal recovery in secondary forest and forest fragments.

The proposed budget was devoted entirely to purchasing the wide array of materials necessary for the effort — cameras, acoustic recorders, and batteries—along with the international travel needed to bring the project to fruition.

In March 2020, all of Luther’s efforts came to a halt due to the pandemic. Additionally, one of the key members of the planning team, Tom Lovejoy, passed away in December 2021. Lovejoy was recognized as one the world’s leading conservation biologists and often referred to as the “godfather of biodiversity.” With Lovejoy’s passing, Luther lost a mentor and a critical member of the team.

However, Luther stayed the course, revamping his team and rewriting the schedule. Finally, in June 2022, he received the green light to move ahead. Between June and October 2022, 136 cameras and 81 acoustic devices were installed across 50 sites at BDFFP.

Today, to Luther’s great delight, the results have proved far more successful than he could have ever anticipated. Tens of thousands of animal images from camera traps and audio recordings have already been collected.

To analyze the data, Luther built a team of 15 George Mason undergraduate researchers, artificial intelligence (AI) experts, and members of Arbimon, a nonprofit organization that specializes in analyzing acoustic recordings from the tropics to identify animals.

The student volunteers on this project included Alexis Lembke, Amanda Jones, Adriana Em, Madison Cheung, Morgan Ellingsworth, and Grace Carriero. Aline Medeiros, a PhD student in environmental science and policy, helped manage the undergraduate researchers working on the audio files. Medeiros will also use the captured data as the basis of her PhD research.

Another set of students helped identify animals in the camera images and entered that information into a large database. Hibo Hassan, Jordan Seidmeyer, Katie Russell, Carolian Sanabria, Adrian Em, Alix Upchurch, Piper Robinson, Tristan Silva-Montoya, and Estefany Umana spent hours creating this treasure trove of records. Emilia Roberts, a master’s student in environmental science and policy, managed these undergraduate researchers.

Discussing the project, Luther explained that, for the acoustic recordings, they built templates for 250 bird species and trained AI models to automatically detect and classify songs for each.

“The model performed very well in our evaluations. We have already detected 201 of the 250 species,” said Luther, who teaches in the Biology Department of George Mason’s College of Science. “Thanks to our model, new recordings can be passed through it to automatically detect species calls, facilitating long-term monitoring and efficient analyses moving forward. We are now working with local experts in Manaus, Brazil, to apply the same platform for frogs at our study sites in the Amazon rainforest.”

The biodiversity data is being used to assess how each species responds to variations in forest structure and recovery from forest fragmentation. Luther brought on Konrad Wessels from George Mason’s Geography and Geoinformation Science Department to assist with satellite information from the Global Ecosystem Dynamics Investigation instrument, which uses high-resolution lasers to provide detail in three-dimensional forest structure. These results will build predictive models to study how the forest structure can forecast mammal and bird diversity and individual species occurrence in tropical rainforests.

In an important finding, the team has determined that the three-dimensional complexity of the forest structure, as measured by foliage height diversity, is the biggest predictor of mammal and bird diversity at this research site, and potentially others, in the Amazon rainforest.

The project continues to gain traction. The team has created a website featuring the results of the acoustic portion of the research, which has been very well received. Some of the acoustic training models have been used by teams competing for the X-Prize, a competition designed to encourage technological developments supporting “radical breakthroughs for the benefit of humanity.”

Building on the 4-VA funded study, Luther also received a $200,000 National Science Foundation grant to continue both the camera and acoustic research. Luther and Wessels recently submitted a grant to NASA to expand on the research findings and apply them to the entirety of the Amazon basin.

“Through 4-VA@Mason, this project is up, running, and delivering fantastic information that will help scientists worldwide better design monitoring schemes for biodiversity in remote tropical forests, as well as those interested the relationship between habitat structure and degradation and species resilience to disturbance,” said Luther.

Since putting the first man on the Moon in 1969, scientists have continued to push our knowledge and understanding of life and existence in vast unknown frontiers of space. Whether through Mars colonies or alien life forms, we're all wondering what and who can survive beyond Earth's atmospheres.

In this episode of Access to Excellence, associate professor of computational and data sciences Anamaria Berea discusses her research on Mars settlements and Unidentified Aerial Phenomenon as she and President Gregory Washington debate the question on everyone’s mind: is there life beyond Earth?

^{"So we have an unidentified phenomenon, so it might be a new physical or atmospheric phenomenon that we haven't discovered yet, right? Because we don't know everything in science right now. Until we can actually scientifically analyze these, it's really difficult for us to say: what are these things? And we cannot say that only based on public opinion or allegations. We do need rigorous scientific studies so that we can turn that unidentified into identified."}
