UM Joins National Cohort of Universities Studying Disaster ReadinessOXFORD, Miss. – A University of Mississippi professor has begun studying the impact of mining waste structures as part of a national initiative to improve disaster readiness. The U.S. Department of Commerce’s National Institute of Standards and Technology and the National Science Foundation have awarded more than $7 million in grants to support natural hazard preparedness to 15 universities across the nation, including Ole Miss. Each university will tackle an aspect of disaster readiness, from how to build structures that can survive storm wave impacts to creating damage prediction models for earthquakes, fires and floods. The Disaster Resilience Research Grant allotted nearly $400,000 to Thomas Oommen, UM chair and professor of geology and geological engineering, and Sidike Paheding, assistant professor of computer science at Fairfield University, to study mine tailing impoundments, massive structures that store mining waste. “With the increased interest in green energy and battery technology, the need for critical minerals and mining is increasing,” Oommen said. “That means mine tailings are going to be more and more prevalent, but monitoring these dams is a challenge.” Mining operations leave behind massive amounts of slurry, or solid waste, that is stored behind dams constructed of the same waste material, Oommen said. While some of the materials are harmless – such as rock, sediment and other debris – others are toxic, including arsenic, lead, uranium and other compounds.
The Kennecott tailings dam near Salt Lake City failed in 1941, 1964 and 1998. In a project funded by the National Institute of Standards and Technology, UM professor Thomas Oommen and Sidike Paheding, of Fairfield University, are using satellite imagery and environmental data to develop ways to assess the integrity and safety of mine tailing impoundments to avert such disasters. Submitted photo When these dams fail, a flood of waste has been known to reach more than 6 miles from the dam site, Oommen said. A dam in Brumadinho, Brazil, failed in 2019, sending a wall of waste and mud into a small town more than half a mile away, killing more than 240 people. “Mine tailings dams are really large geotechnical, earthen structures, and they’re prone to failure with extreme weather events,” Oommen said. “The consequences of failure can be catastrophic both in terms of casualties and environmental effects.” Similar failures have happened in Mississippi. In 2005, a phosphate mine tailings dam failure allowed more than 17 million gallons of acidic liquid to pour into surrounding marshland, killing vegetation near Bangs Lake in Jackson County. Some 12,563 mines are active across the United States, but there is no rough count of how many mine tailings dams exist. When mines shut down, oversight of the impoundments often becomes lax, Oommen said. “The challenge is when the mining operation is happening, there is a lot of interest in the dam and its upkeep, but once the operation is done and there is no more revenue being generated, the companies are gone,” he said. “So, who is going to maintain this? Often, it becomes no one’s property or it falls into the hands of the government to maintain it. “So, maintaining and monitoring these tailings dams is a challenge, especially if you have to do it manually, using traditional methods.” Oommen and Paheding’s research will use satellite and environmental data to detect whether a dam is at risk of failure. They will also use historical weather records to determine what correlation, if any, there is between hazardous weather and dam failures. “We need to prevent environmental damage, especially if there are residents living in nearby areas,” Paheding said. “Our goal is to provide a technological solution to prevent these incidents.” Using satellite imagery and environmental data, Paheding and Oommen hope to develop an advanced machine learning model that can identify potential issues, Paheding said. If successful, the technology would allow remote monitoring of mine tailing impoundments and help predict when a dam is becoming unstable, Oommen said. “From my perspective, I hope we can have a sophisticated algorithm that can be utilized to solve this problem,” Paheding said. “We don’t want have something that works in theory; we want to have something applicable in a real-world scenario.” This material is based upon work supported by the National Science Foundation under grant No. 2414588. |

OXFORD, Miss. – The University of Mississippi is once again one of the nation’s “Great Colleges to Work For,” according to The Chronicle of Higher Education.
This is the 14th year that the university has been named a Great College to Work For. Ole Miss joins 42 other Honor Roll schools recognized this year as standouts in their size categories.
“This outstanding distinction of being a great place to work is an incredibly high honor especially our recognition on the Honor Roll and across all 10 categories,” Chancellor Glenn Boyce said. “It really speaks to the culture of caring and collaboration that permeates our campus community.
“Our tremendous people deeply believe in and support our mission, which makes this university a truly special place to live, work and learn.”
The results were released Monday (Sept. 11) in a special insert of The Chronicle. Of the 194 institutions participating in 2023, 72 were recognized as a Great College to Work For.
For the first time, the university earned honors in all 10 recognition categories. The categories are:
- Job Satisfaction and Support
- Compensation and Benefits
- Professional Development
- Mission and Pride
- Supervisor/Department Chair Effectiveness
- Confidence in Senior Leadership
- Faculty and Staff Well-being
- Shared Governance
- Faculty Experience
- Diversity, Inclusion and Belonging
Great Colleges to Work For is one of the largest and most respected workplace recognition programs in the country.

“Over the past 14 years, it has been rewarding to watch UM continue to gain momentum with the GCTWF recognition, with this year hitting the peak of honor recognition in all 10 categories,” said Andrea Jekabsons, chief human resources officer. “Specifically, the HR team contributes to the success in the areas of compensation and benefits, professional development and faculty-staff well-being.”
Jekabsons said she strives “to lead by example” by encouraging campus supervisors and managers to provide the tools, resources, coaching and time off for employees to experience balance and an enriched work-home environment.
“Offering a supportive and encouraging environment contributes to the employees’ well-being and, in turn, provides the benefit of an exceptional experience for our students,” she said. “There is no doubt that we are a great place to work because of our people, and this is further evidence of that.”
ModernThink, a strategic human capital consulting firm, administered the survey and analyzed the results. Results are based on a two-part assessment process: an institution questionnaire that captured employment data and workplace policies from each institution, and a survey administered to faculty, administrators and professional support staff.
Employee feedback is the primary factor in deciding whether an institution receives recognition.
Richard K. Boyer, principal and managing partner at ModernThink, said that this year’s Honor Roll designees outperformed the applicant pool by an average of 38 percentage points on the survey statement, “Senior leadership shows a genuine interest in the well-being of faculty, administration and staff.”
That 38-percentage-point difference was mirrored on the statement, “Senior leadership provides a clear direction for this institution’s future.”
“Once again, leaders at the institutions recognized in this year’s Great Colleges to Work For program have demonstrated their collective commitment to the stewardship of their institutions’ cultures,” Boyer said. “Their commitment to the well-being of their faculty and staff is second to none.”

Geology student awarded national geophysics scholarship
As a child, Ole Miss geology student Elsie Buskes loved dinosaurs.
She planned on studying paleontology to pursue this interest – until a super internship opportunity sparked her interest in geophysics, especially issues related to water quality.
Her passion for this field is why she is the sole undergraduate recipient for this year’s Environmental and Engineering Geophysical Society (EEGS) scholarship. The $1,000 award goes to students interested in pursuing a career in near-surface geophysics to help meet the challenges of the future.
Elsie will be recognized for this honor at the 2024 Symposium on the Application of Geophysics to Engineering and Environmental Problems, as well as having her essay published in the EEGS news magazine.
This award is a testament to the hard work and dedication Elsie has put into her work, and I am proud of her accomplishments to date. I hope this award will serve as a springboard for greater achievement in her study.
– Leti Teklu Wodajo, Research Scientist, National Center for Physical Acoustics
Learning about water problems
In January 2022, Elsie heard about an internship with the National Center for Physical Acoustics (NCPA) through an Honors College email.
The porous media group within the NCPA was looking for a geology or geological engineering student who could help with their research into drinking water problems in a time of increasing population demand. It’d require the use of geophysics to help discover water sources and determine the best way to extract it.
Elsie explained that she didn’t know much about the field, but she was excited to learn about it.
She spent her first months undertaking preliminary research tasks under the guidance of NCPA research scientist Leti Wodajo. Basically, this helped Elsie gain basic physics knowledge and learn how to apply to real situations.
By the summer of 2022, she was able to take part in her first geophysics survey. The team used electrical resistivity tomography – a technique using multiple electrodes to investigate groundwater and soil moisture.
I learned tons about surveying methods. We were looking for an aquifer at the Ole Miss Field Station and trying to figure out the best place to drill a well.
– Elsie Buskes
The team presented their findings at the Geological Society of America and Mississippi Water Resources Conference, and Elsie gave an explanatory talk at the Ole Miss Field Station.
Elsie’s work for the NCPA will be the basis for her honors college thesis.
Wodajo highlighted that “this is a great example of the collaborative work between the School of Engineering and the NCPA, where students gain hands-on research experience tackling pressing problems the nation is facing.”
Expanding her knowledge
Like all Ole Miss geology and geological engineering (GGE) students, Buskes spent two weeks at field camp in Oklahoma as course credit.
In the classroom, she’d used cardboard to learn how to measure strike and dip – the convention for describing the plane orientation of a geologic feature. But, at the 2023 field camp, she was able to put this into practice, identifying mineral structures and characteristics.
“I was able to take my textbook knowledge and actually apply it. It was great to take measurements on real bedding surfaces. I definitely learned a lot.”
– Elsie Buskes
She also learned about working with others.
She and the other students were tasked with estimating the cubic volume of rock at a historic site known as Ten-Acre Rock. Some students walked the perimeter, measured the height and calculated the volume from there. Others used GPS and geometry to try to solve the problem, while another group took a calculus route.
I think it was better to let people do what they want and pull the data together at the end. That way, everyone could test out their approach and learn from others which way was the best.
– Elsie Buskes
She also worked on a U.S. Geological Survey research project for GGE professor Jennifer Gifford. Five students helped map out a small section of the Big Horn Mountains – at a dizzying height of 9,000 feet and higher.
Elsie is from Oxford, MS. She’s a junior, majoring in Geology and participating in the Sally McDonnell Barksdale Honors College.
Geohazards Expert to Lead Geological Engineering Department
Thomas Oommen brings more than 10 years of experience in research and academia

OXFORD, Miss. – Thomas Oommen, an expert in geohazard risk assessment, is slated to join the University of Mississippi School of Engineering as chair of its Department of Geology and Geological Engineering.
“I believe in the immense potential of the department, and I am committed to creating a positive and supportive environment for all the members,” said Oommen, who is coming to Ole Miss after spending more than a decade at Michigan Technological University.
“As the department chair, I will prioritize academic excellence, promote scholarly research and foster a culture of collaboration and innovation.”
At Michigan Tech, Oommen is a professor in the Department of Geological and Mining Engineering and Sciences and the director of its computational science and engineering doctoral program.
His research interests include geohazard risk assessment and critical infrastructure system monitoring. He has adopted an interdisciplinary research approach that integrates geological engineering concepts with tools from two main areas: remote sensing for obtaining data and artificial intelligence and machine learning for data processing and modeling.
He has received more than $10.5 million in research and travel grants for his work. One of his recent projects, funded by the National Science Foundation, is designed to help develop tools that rural counties can use to enhance flooding and coastal disaster resilience.
He also has received a grant from the Federal Railroad Administration to create an automated decision support system to monitor ground hazard risks such as landslides.
His ambitions extend to the geology and geological engineering department.
“I aim to enhance the department’s reputation and visibility by cultivating research partnerships with other institutions, organizations and industries,” he said. “I am eager to showcase the accomplishments of the department’s members to a broader audience and raise awareness of the department’s contributions to the field.”
Oommen has led Michigan Tech’s computational science and engineering doctoral program since 2019. Since, he has significantly grown the program – leveraging the available resources and attracting new faculty to participate in the interdisciplinary program. He also has mentored several students in pursuing prestigious fellowships.
“To drive a successful graduate program, it is important to have funded research projects and it is equally important to mentor students to apply for competitive fellowship programs like the NSF graduate research fellowship, NASA’s FINESST program, the Department of Defense’s SMART fellowship and more,” he said.
Oommen received his doctorate in civil and environmental engineering from Tufts University with an emphasis in geotechnical engineering. Before that, he obtained a master’s in geological engineering department of the University of Alaska at Fairbanks and his bachelor’s in engineering from Bangalore University.
He joins the School of Engineering team in August. Gregg Davidson, who has been the department chair since 2013, will return to full-time faculty status.
Drilling Down on a Win-Win Collaboration

OXFORD, Miss. – A joint research drilling project between the Mississippi Mineral Resources Institute at the University of Mississippi and a northeast Mississippi mining company is producing benefits for both partners.
MMRI and Profile Products in Blue Mountain are in the middle of the ongoing project, which began in May. Profile Products mines the clays of the Porters Creek Formation in Tippah County and produces products used to construct and maintain athletics fields across the country.
Researchers and students at MMRI and the UM Department of Geology and Geological Engineering are drilling a series of test holes on property leased by the company.

“The project is an ideal opportunity for both Profile Products and the University of Mississippi to collect important research data,” said Greg Easson, MMRI director and professor of geology and geological engineering.
“The UM research team was provided access to an ideal site to conduct a drilling campaign that can be used to validate geophysical methods for subsurface characterization. In addition, the team gets samples of the clay for a geological analysis of its character and origin.
“Meanwhile, Profile Products acquires the data they need to determine the amount of clay reserves on the property and samples for testing in their in-house lab to maintain consistency in the products they produce.”
The team is using a drill rig purchased with funds provided by the Mississippi Legislature through a grant program from the Mississippi Board of Licensure for Professional Engineers and Surveyors. During the drilling process, data are collected from the layers of clay being mined and continue through the different types of soil underneath the earth’s surface.
Subsurface samples collected are divided in the field, with half of them provided to Profile Products for testing in its lab to see if the material meets its specifications.
The other half of the samples for each depth will be retained and analyzed by the UM research team to help understand the geological history and origin of this geological formation. Findings will form the core of an Ole Miss graduate student’s thesis.
As part of the research team is drilling, other researchers and students are collecting geophysical data along the same path. The methods for collecting geophysical data include ground-penetrating radar, electrical resistivity and passive seismic (the detection of natural, low-frequency earth movements).

Data collected using these methods will be compared to the drilling data to determine the accuracy of the geophysical methods.
“Profile Products has agreed to provide the UM team access to the site so that we can process the data, reconfigure the systems and collect another set of data,” Easson said. “This research will provide the UM research team with validation of the level of accuracy of the geophysical data to show how these methods can be used in areas where drilling is not allowed, such as levees on the Mississippi River.”
The partnership between the company and MMRI is mutually beneficial, said Chas Goff, plant manager at Profile Products.
“The reserve data will allow Profile Products to expand our operations,” Goff said. “The students are learning how to drill safely and how to sample and work with clients.”
The drilling and reserve estimate for the project will be completed by the end of July, with analysis and additional geophysical data collection continuing into September.
