Currently, as a PhD candidate, Hines is actively involved in George Mason’s Clayborne Research Group where her graduate research initially focused on nanoscale aluminum clusters using density functional theory (DFT). Inspired by her participation in NASA’s Dragonfly Guest Investigator Program, her current work explores computational studies of molecular co-crystals in astrophysics and astrochemistry.

The Dragonfly Guest Investigator Program facilitated Hines's collaboration with NASA's Jet Propulsion Laboratory, where she participated in a Planetary Science Summer Internship. This program pairs students with NASA scientists to bolster early career opportunities in STEM fields. During her internship, Hines investigated the behavior of complex mixtures of organic and aqueous ices pertinent to Titan's conditions, directly contributing to NASA's exploration objectives.

"The program has been transformative, providing me with hands-on experience and expanding my scientific horizons," said Hines.

Hines said that her George Mason mentors, including Gerald Weatherspoon, College of Science’s associate dean for undergraduate and graduate student affairs, have been a source of encouragement and inspiration. Her research advisor, acting associate dean of faculty affairs in the college and chemistry professor Andre Clayborne, introduced her to computational chemistry and has been instrumental in helping her understand and explore new areas of research.

Hines offers this advice to aspiring STEM students: "Believe in yourself and follow your dreams. Build connections and seek research opportunities early." She encourages all eligible students to consider applying for the DoD SMART Scholarship.

Looking ahead, she envisions a career as a research scientist, leveraging her experience to continue making discoveries and collaborating with top scientists in her field.

George Mason scientist identifies 1,000-year-old seedling linked to biblical myrrh Katarina Benson Wed, 01/08/2025 - 14:50

George Mason �鶹�� researcher Andrea Weeks played a key role in identifying an ancient seedling linked to the biblical myrrh. The seed, a yellow and fragrant resin from the Commiphora tree, was discovered in the Judean desert and revived by a team of researchers.

Weeks was invited to join the project, led by Hadassah �鶹�� Medical Center in Jerusalem, because of her expertise in the evolutionary biology of Commiphora. Her extensive DNA sequence database played an instrumental role in analyzing the genetic makeup of the ancient specimen. Morgan Gostel, Weeks’ former PhD student and current research botanist at the Botanical Research Institute of Texas, also played a critical role in this research.

While the team confirmed the seedling’s genus, they have yet to pinpoint its precise species. “Its exact species remains unclear, highlighting the need for further biodiversity research. No lab has yet tested every species of Commiphora,” said Weeks, who is an associate professor in the Department of Biology in the College of Science and the director of George Mason’s Ted R. Bradley Herbarium.

One of the most puzzling aspects of the discovery is the seed’s location. Found in a Levantine cave, the seed had been preserved for centuries in an area far outside the modern range of Commiphora.

“Radiocarbon dating reveals that this seed formed long after biblical times, but that doesn’t explain how or why it ended up in a cave in the Judean desert 800 to 1,000 years ago,” said Weeks.

Funding from previous grants awarded to Weeks by the National Science Foundation (NSF) helped lay the groundwork for her involvement and impact in this discovery of the ancient seed, which the researchers selected to call “Sheba.” “The use of NSF-funded data in identifying Sheba shows how foundational research can have lasting, unexpected benefits,” she said.

The study’s findings could significantly influence future research on biodiversity by enhancing our understanding of historical flora and their evolution within current ecosystems.

The interdisciplinary nature of the research, combining archaeology, ethnobotany, chemistry, and plant taxonomy, contributed to the team’s success. Moving forward, Weeks and her lab plan to deepen their exploration of Commiphora diversity. “Like most scientific inquiries, this project leaves us with more questions than answers,” Weeks said. “It sheds light on the complexity of biodiversity and also serves as a reminder of life’s interconnectedness across time.”

Ermagun, assistant professor in the Department of Geography and Geoinformation Science in Mason's College of Science, leads a National Science Foundation (NSF)-supported project titled “Snuff It Out: Extinguishing the Disparity of Access to Shelters for Disadvantaged Communities in Wildfire-Prone Areas” to optimize response to the growing menace of wildfires.

The project will address shelter access when wildfires occur and has the potential to revolutionize disaster preparedness and response strategies, serving as a blueprint for fostering resilience in communities facing the escalating threat.

This collaboration, supported by a $397,365 NSF grant, focuses on disaster resilience in Lake County, California, which grapples with persistent wildfires. The comprehensive examination of shelter access differences, in a broader sense, also seeks to better comprehend the challenges faced by marginalized communities in California.

“Access to shelters is indispensable in transforming wildfires from potential tragedies into manageable emergencies,” said Ermagun. "The project involves the development of an interactive map, serving as a platform for both public officials and community members to plan and implement disaster resilience strategies.”

Since 2015, wildfires have consumed more than 60% of the county, disproportionately impacting its disadvantaged residents. With wildfires increasing in severity and frequency, Ermagun stresses the urgency of this research, which unfolds in three phases: assessing disparities of access, optimizing equity through preparedness strategies, and developing an interactive model to reduce the vulnerability of marginalized communities to wildfires and the cascading hazards such as debris flows and flooding.

The “Snuff It Out” project employs an interdisciplinary approach, collaborating with Farshid Vahedifard from Tufts �鶹��, Chief of Police Kathy Lester of the Sacramento Police Department, Leah Sautelet from the Lake County Sheriff’s Office, and Nick Widmer and Gabriela Perez Albarracin from the American Red Cross.

Vahedifard emphasized the importance of community collaboration in addressing natural hazards, stating, “Having been fortunate to have very supportive community partners in the study area, we aim to work closely with the community to co-develop and implement a methodological framework to improve access to shelters during natural hazards and extreme events for all communities while prioritizing marginalized communities to account for their lower risk threshold and adaptive capacity.”

Echoing the commitment to community collaboration, Sautelet, serving as the emergency services manager for Lake County, articulated the synergy between the project’s aims and local emergency management objectives. “Utilizing this innovative interdisciplinary approach, the project has the potential to strengthen both public welfare and emergency management endeavors," she said. "Rooted in Lake County’s steadfast dedication to protecting public safety, the project seamlessly aligns with our overarching objective of enhancing community resilience as a whole. By providing crucial data for comprehensive planning and preparation, it seeks to reinforce our ability to respond effectively during times of crisis.”

Lester, expressing support for the initiative, highlighted its potential to make a significant societal impact. “This research project has potential widespread benefits to society by improving the resilience of disadvantaged communities and helping first responders with science-based tools to improve outcomes.” Lester’s enthusiasm underscores the project’s aim to empower both communities and first responders through evidence-based strategies.

Adding to the collective vision, Ermagun focused on the project’s commitment to addressing social inequalities, “We aim to address equity discrepancies and enhance community resilience faced by the residents during these ongoing challenges,” underscoring the project’s community-centered methodology.
