The UT Tower


110 Inner Campus Drive

A 307-foot sentinel at the heart of the Forty Acres, the Main Building’s Tower is one of Texas’ most notable landmarks. Just a foot shorter than the nearby Capitol Building, the UT Tower was built on a hilltop, higher above sea level than its neighboring landmark. The building interacts with — and holds critical information about — the natural world: The National Weather Service has long used the Tower to help measure Austin’s cloud ceiling, and lately a peregrine falcon has made its home in the belfry. Massive collections of plant specimens and life sciences texts, beautiful images of scientific discovery on the UT campus, and artwork that celebrates the wonders of nature over time all have a place within Main. And over the years, eight University presidents occupying the top leadership office on campus here on the fourth floor did so after having started as faculty members in the sciences.

A female peregrine falcon, nicknamed “Tower Girl,” nests in a wood box high up on the north side. The public learns from scientists in the University’s Biodiversity Center who help explain the usually solitary falcon and what her experience as a wild urban predator tells us about broader issues of land use and species interaction in Texas.


Life Science Library

The Life Science Library on the second floor displays a sculpture on loan from New York’s Metropolitan Museum of Art. Sculptor Walter Dusenbery used geometric calculations to guide how limestone would be carved into a structure that celebrates the wonders of nature through time. Pedogna is made from a type of limestone called travertine, containing mineral and biological impurities within the white stone that imbue the piece with a rainbow of hues. The sculpture is one of several scientifically or nature-inspired art pieces procured by Landmarks, the university’s public art program, which makes art free and accessible to all on campus.

Science Out in the Open
The UT campus


University Avenue and Inner Campus Drive

Between more than a dozen buildings where Natural Sciences research and learning take place are spaces where our Texas Science community explores, investigates and engages with life all around in the great outdoors. Natural habitats like Waller Creek and the UT turtle pond offer a scientific sandbox, where students of the life sciences have up-close encounters with organisms large and small, with whom they share the campus. Among the researchers are leading biologists in our top-ranked ecology, evolution and behavior program, including several members of the National Academy of Sciences. Their research is illuminating new insights into the health of critical species, from honeybees to salamanders. The groundbreaking research these scientists do happens not only on campus and in biological science buildings such as J.T. Patterson Labs, Neural and Molecular Science, Moffett Molecular Biology and Biological Laboratories but also at UT’s top-notch field stations, which are located off the Forty Acres.

The Turtle Pond on UT Campus


Waller Creek

Waller Creek, a verdant corridor teeming with life, is a little bit of wilderness tucked away in the heart of campus. While its picturesque waters and the nearby slopes enhance the beauty of the Forty Acres, it also serves as a laboratory for students and citizen scientists to get a taste of field work. The creek boasts an impressively diverse list of species, with more than 500 kinds of plants, animals, insects and fish, according to the team of biologists, geoscientists and volunteers who maintain a digital archive of the biota of Waller Creek. Members of the Freshman Research Initiative examine sources of bacteria in the creek, following in the footsteps of earlier scientists whose discoveries there led to breakthroughs. For example, a rare, fast-growing type of blue-green algae found only in Waller Creek was first identified in the 1950s. Today, because of its tendency to feed off of sunlight and carbon dioxide, it is being explored as a potential resource to fight greenhouse gas emissions.

Can you take a snapshot of a memory within the brain—elusive and diffuse as a wisp of smoke, encoded like some secret spy code in the shapes and sizes of delicate connections between brain cells? Neuroscientist Kristen Harris is aiming to do just that by pioneering methods for reconstructing the 3D structures of synapses and other important features of the nervous system using electron microscopy. Her work is leading to a deeper understanding of the physical changes that occur in the connections between brain cells as we make memories and learn, as well as how diseases like Alzheimer’s alter brain structures. Harris’s research is part of the National Science Foundation’s Brain Initiative, which is pursuing one of science's grandest challenges: understanding how the brain works.

Gearing Hall


200 W 24th Street

Through the halls and picturesque courtyard of Gearing Hall have walked true giants of child development, nutritional science, public and community health, and textiles and apparel. Among them were some of the first women to chair university departments anywhere—and to preside over this University in particular. Here big thinkers came up with ideas that have changed the contours of fixtures in many everyday lives, shaping the trajectory of everything from Sesame Street to Head Start preschools. And today students and researchers continue delving deeply into the science at the crux of our human experiences. For Longhorns that means getting real—in laboratories, research, internships and projects — with learning that’s active and ideas that matter.

Public health is rooted in lessening health disparity and noticing trends in different demographics. That is what I'm passionate about. It’s interdisciplinary and it’s global, with a mixture of statistics, culture, history, social sciences and natural sciences. It will make me a more well-rounded doctor. – Kayla Eboreime, pre-med and public health major

Public health is one of four undergraduate majors housed in the School of Human Ecology, along with Human Development and Family Sciences, Textiles and Apparel and Nutritional Sciences.


For nearly a century, local preschoolers have learned on campus, while child development researchers learn from them. One class returned to campus 70 years after they were preschoolers together and reunited with their UT teacher.

A Scientific Hub at UT’s Heart
Welch Hall


105 E 24th Street

The largest academic building on campus, Welch Hall serves as a nucleus of discovery, learning and research, as chemists, biophysicists, molecular bioscientists and students blend approaches to make cutting-edge discoveries. The people who walk these halls begin in one area, like our highly ranked chemistry program, and go on to create lasting impact in industry, academia and government. This is hallowed ground, where discoveries have been made that mean life-saving medical diagnoses and technologies that improve the devices which today power our lives. The project list continues: from solar energy to microprocessors to determining the structure of proteins responsible for Alzheimer’s disease. Modern research and learning spaces here are catalyzing the next generation of breakthroughs.

Learning Laboratory


The building, currently under renovation, is known for its grand hallway, which when it reopens will be a brightly lit gathering area celebrating scientific discovery and community on the UT campus.

For more than seven decades, chemistry research here has been linked to breakthroughs that help prevent birth defects. In 1941, in the original wing of the building, UT biochemist Esmond Snell discovered folic acid, which was later shown to prevent birth defects like spina bifida. Decades after Snell’s experiments (involving four tons of spinach!), a scientist who studied under Snell helped to train Dean Appling, a current professor in the Department of Molecular Biosciences. Appling was among the scientists who urged fortifying more foods with folic acid. The change has led to a dramatic drop in birth defects and related disabilities and deaths in babies around the globe. Working in Welch Hall, Appling’s team also discovered a gene that, when functioning improperly in mice, causes embryos to be born with birth defects. He continues, alongside other faculty on campus, to research factors in the prevention and treatment of birth defects.

Professor Eric Anslyn's “Supramolecular Sensors” research stream, a lab within the Freshman Research Initiative, lets students apply technology to construct differential chemical sensors that are capable of distinguishing the subtlest of differences in various samples. The tests can illuminate different varietals of wine, for example, revealing—forensic-investigator style—the chemical fingerprints of a wine sample. That can be helpful in preventing counterfeits and a lot more.

“I like to present cool case studies of scientists using techniques similar to ours to detect diseases,” says Brenden Herrera, now a graduate student and mentor for the lab that he first entered as an undergraduate researcher himself. “We have to make it relevant.”

Pushing Beyond the Known


2515 Speedway

On a campus where we say, “What starts here changes the world,” people in the Physics Mathematics Astronomy building know that what starts here changes conceptions of the universe. World-class educational and research programs in physics, math and astronomy usher in new understanding, made possible by mathematical solutions to technological and natural problems and new experimental discoveries about happenings in faraway galaxies or distant solar systems. Physicists established one of the world’s most powerful lasers in the basement; on the roof, campus visitors peer through a telescope to explore the cosmos; and in between, learners and researchers unravel mysteries in some of the nation’s best-ranked programs in mathematical and physical sciences. The top-to-bottom boundary-pushing happens not only here but also beyond these walls, as these scientists leverage the power of world-class facilities like UT Austin’s McDonald Observatory in West Texas and the Texas Advanced Computing Center at the JJ Pickle Research Campus.

Physics, Math and Astornomy Library at PMA

The entry floor of the building, on the fourth floor, is home to one of the most prominent on-campus displays of winners of the annual Visualizing Science contest. Hosted by the College of Natural Sciences, the competition celebrates where art and beauty collide with science and the scientific process, as hundreds of students, faculty and staff researchers submit their favorite images of their work. Among the winners in 2017 was mathematics graduate student Arun Debray, whose image shows a Newton fractal. To make it required applying what is known as Newton's method to understand where a function is equal to zero. Small changes in the input can lead to large differences in the output, resulting in the fractal graphed here. Color represents the output of the algorithm, while shading represents its convergence time.
