Academic Research

As a Loyola student, you have the opportunity to work alongside our talented professors to partner in collaborative research. Learn more about some recent research and projects currently underway.

Social and Biological Influences on Primate Behavior and Reproduction

Dr. Evan Zucker, Professor of Psychology, studies the social and biological influences on the behavior and reproductive outcomes of nonhuman primates, as well as studying naturally-occurring patterns of human behavior (human ethology) and other aspects of social phenomena. His recent research has focused on the relationship between familial social status and life-history variables, as well as how indices of health in black howling monkeys are related to ecological factors, group composition factors, and reproductive status.

Conservation of imperiled Okaloosa Darters

Since 1992, Professor Frank Jordan and students from the Department of Biological Sciences and the Environment Program have been collaborating with stakeholders from the US Geological Survey, the US Fish & Wildlife Service, and the US Air Force to study the biology, ecology, and conservation of imperiled Okaloosa Darters. This species of small fish is geographically limited to six small streams that are located primarily on Eglin Air Force Base in northwestern Florida. These studies included annual population monitoring surveys at a network of about 20 sites; periodic range-wide surveys at over 50 sites; development of sampling statistics and evaluation of visual sampling methods; characterization of microhabitat abundance and use; restoration of impounded stream sections; analysis of population genetic structure; analysis of movement and longevity; and most recently quantifying effects of canopy removal. Collectively, results of these studies largely informed the decision to “downlist” the species from Endangered to Threatened status in 2011 and more recently to the proposal by the USFWS to remove Okaloosa Darters from the Endangered Species List altogether. This will be a significant conservation milestone because – once listed – few species are recovered enough to come off the List. Read more about this study here.

Biology Research Seminar Series

The Department of Biological Sciences holds a series of seminars each Fall and Spring semester in which Loyola faculty and guest speakers from around the country present their latest research findings. A list of this semester's lineup and an archive of past research seminars is provided here. Seminars are at 12:30 in Monroe Hall 610 unless noted otherwise.

Effects of Rouseau Cane on Coastal Wetlands

For almost a quarter century, Loyola University New Orleans biologists and ecologists Donald Hauber, Ph.D., Craig Hood, Ph.D, David White, Ph.D., and numerous undergraduate honors students, have studied the origination and effects of the common reed known locally as Rouseau Cane on the marshes and coastal wetlands of southeast Louisiana.

“Rouseau Cane has dramatically increased in the coastal wetlands along the Atlantic and Gulf Coasts during the past century,” White said. “The species’ spread is mainly due to the introduction of new gene types from Europe. These invasive types are becoming more common in the interior marshes of the Mississippi River Delta, land that is extremely rich in nutrients.”

The Mississippi River Delta covers an area roughly 521,000 acres, but during the last 40 years, it has been significantly reduced due to lack of river sediment coupled with high natural subsidence.

P. australis is the dominant emergent vegetation in the Delta’s outer two-thirds and is believed to play a major role in stabilizing these extensive marshes by breaking wave action and storm surges from the open Gulf while also capturing and retaining river sediment. “This stabilizing role protects the diverse interior marsh communities that provide food and breeding habitat for wildlife, particularly birds,” said White.

In recent years however, the new European gene types of P. australis, have begun to expand into the interior marshes displacing food and habitat resources for wildlife. This new invasion into these inner marshes is thought to have negative impacts on sustaining the migratory and local wildlife.

The researchers have been monitoring the spread of the Rouseau Cane through aerial views of the wetlands to study the impact from above. Flights have confirmed that the invasive types of P. australis is spreading throughout their research sites in the inner marshes of the delta. In a similar flight during the spring of 2006, White observed small areas of the invasive P. australis that are now much larger and spreading to other areas outside the delta. The Deepwater Horizon Oil Spill caused some coastal wetlands loss along the very margins of the delta’s shoreline, according to the researchers. "The total wetland loss in the delta is remarkably low as a result of the spill, though any loss is very troublesome,” White said. “The small amount of loss is partly due to the freshwater sheet flow that kept oil away from the delta freshwater wetlands, and partly because of the peripheral stands of the P. australis which became the frontline physical barrier to oil invasion inland.”

Virtual Reality Simulations for Physics Education

When studying physics, we can study large systems (such as free fall under gravity or even galaxies) or small systems such as atoms in a crystal. For many technological applications, it is essential to study the property of matter rooted in the arrangement of atoms in solids. Solid-state physics is a branch of physics that focuses on how the arrangement of atoms can lead to different (electrical, magnetic, mechanical, etc) properties of materials. This is critical when looking for materials to advance the current technologies or to propose new solutions. In real life, physicists and engineers investigate small-scale physics (for example, using advanced transmission electron microscopy techniques). They measure properties of that same system and try to come up with theories that build the bridge between the arrangement of atoms and the properties that we can measure in the lab (for example, electrical resistance). One challenge that all of us face when doing this kind of research is the three-dimensional visualization of atomic structures. Our books, our notes, even monitors provide two-dimensional visuals... 
Dr. Beik Mohammadi and her research team use virtual reality (VR) simulations to developed interactive three-dimensional structures to enhance solid-state physics education. Using such models helps us dive deeper into the three-dimensional word of atoms in a fun interactive way! The hope is to teach solid-state physics to physics and even non-physics majors!

Quantum Optics

Experiments using light quanta – photons – have proven to be very effective probes of a large range of phenomena, including quantum entanglement. This phenomenon has long fascinated scientists, and exemplifies the mystery and ‘weirdness’ of quantum physics. It also points the way towards the possibility in the future of extremely powerful quantum computers.

In the Quantum Optics Lab in the Physics Department at Loyola University we have done a successful version of a test of Bell's Theorem using entangled photons.  Our results violate an inequality -- known as the Clauser, Horne, Shimony, Holt (CHSH) inequality -- to a high degree of confidence. These results are in agreement with the laws of quantum mechanics, but inconsistent with any 'hidden variable' extension which attempts to impose locality.

Students are involved in all aspects of the work, from putting together and aligning optical components, to building electronics, to using computers to acquire, analyze and model the data. We have automated most aspects of the experiment and are currently pursuing a variation of the initial experiment.

Gravitational Physics



There is a long history in gravitational physics at Loyola. Professor Emeritus Carl Brans is world-renowned for his development of the scalar-tensor theory of gravity. Known as the Brans-Dicke theory, this modification/extension of Einstein’s theory of General Relativity is still very relevant, and generates a lot of interest, particularly in cosmology, even today.  Carl’s collaboration with the Torsten Asselmeyer-Maluga resulted in their book, Exotic Smoothness and Physics, which surveys extensively exotic differentiable structures on 4-dimensional manifolds and their potential impact on physical theories involving spacetime models.

Former Loyola faculty member Tirthabir Biswas also worked in the area of gravitation and cosmology. He collaborated with a number of Loyola students over the years on theoretical ideas in gravitation with implications for cosmology.

Professor Martin McHugh worked for many years on the experimental side of gravitation. First in tests of the equivalence principle, then in the effort to detect gravitational waves. He worked on resonant mass gravitational wave detectors, then with interferometers when he joined the LIGO Science Collaboration. After being part of that group for nearly 10 years he left to pursue other research interests. However, he was quite gratified when LIGO made the first direct detection of gravitational waves, reported in 2016. That work led to the Nobel prize for the leaders and founders of the project, and gravitational waves have become a tool to study astrophysics, cosmology, and as a probe to a better understanding of the gravitational interaction.

Finally, Professor McHugh has done some work in the history of gravitational physics, in particular the pioneering work of Robert H. Dicke. Dicke made significant contributions in many areas of physics over the second half of the twentieth century. A short list of his accomplishments include the invention of the microwave radiometer, work in atomic physics on the narrowing of spectral lines by use of a buffer gas (sometimes referred to as ‘Dicke narrowing’), and foundational work on the theory of superradiance. But Dicke is best known for his work in gravitational physics – both his pioneering experiments, and his role in the development of the Brans-Dicke theory. The latter, as noted above, done with Loyola Professor Emeritus Carl Brans when he was a graduate student at Princeton. Dicke also played a pivotal role in the discovery of the Cosmic Microwave Background.

Senior Capstone Projects

All majors in French, Latin American Studies, and Spanish prepare a senior Capstone project which is normally presented during their last semester at Loyola. Projects vary greatly, from literary analysis, to concerts, to social research, or whatever makes sense with the student's background and interests. For some examples, click here.


Dr. Walkenhorst is a physical biochemist whose research involves studying the structure, function, and stability of peptides and proteins in solution.  He uses chemical, biological, and instrumental techniques to study several classes of proteins.  His most recent project involves studying the effect of environmental factors such as pH, ionic strength, toxic ions, and surface type on the activity of a new class of membrane active antibiotics called antimicrobial peptides.  He conducts research with undergraduate students interested in careers in biochemistry and medicine.  Dr. Walkenhorst is a founding member of the New Orleans Protein Folding Intergroup (NOProFIG) which began in January 1999 and meets every two weeks to discuss research results of local researchers in related fields.

Dr. Walkenhorst's work has been published in journals such as Antimicrobial Agents and Chemotherapy, Biochemica Biophysica Acta: Biomembranes, Biochemistry, Journal of Molecular Biology, Protein Science, Journal of the American Chemical Society, Analytical Chemistry, and Protein Engineering.

Research in the Schoeffler Lab centers on exploring the sequence-structure-function paradigm as it relates to enzyme specialization. This means we're interested in understanding how changes at the genetic level lead to functional changes in proteins, optimizing them for particular jobs or particular environments. We study “interesting systems with hidden differences”: DNA modification enzymes that work at either near-boiling or near-freezing conditions, RNA modification enzymes that have the same shape but recognize dramatically different biochemical targets. In studying these systems, we ask: What small differences at the atomic level are driving these big differences in the macromolecule, and thus the organism? To interrogate these relationships, we use tools from computational biochemistry and bioinformatics, biochemistry, and structural biology. Our work is basic in nature but has implications for big problems like antibiotic resistance, bioengineering, and the search for extraterrestrial life.

Students and Faculty Work Together on Effective Altruism

Loyola undergraduates Melody Bigelow-Monssen, Emily Ortiz, and Kalya Koonz worked with philosophy professor Leonard Kahn on two effective altruism projects in the spring of 2019. The results was a panel discussion during the university's Earth Week celebration and a scholarly review of William MacAskill's Doing Good Better, co-written by Ortiz and Kahn, which was published in the journal Philosophy in Review.
