Biology

Biology

The major in Biology provides a solid foundation in modern biology. As opposed to majors with an emphasis on specific fields of biology (e.g., Molecular and Cellular Biology, Biochemistry, Ecology and Evolutionary Biology), Biology offers broad training in biological systems from their component parts, biological molecules and cells, up through organisms to communities to whole ecosystems, as well as the biological processes that organize such systems and allow their development and evolution.

Chemistry

Chemistry

Chemistry is often called the central science as it provides the connection between mathematics and the physical, life and applied sciences. Chemistry is the science of molecules and their transformations. Chemists study the composition, properties and reactivity of matter and synthesize and discover new molecules and materials. Since the transformation of matter is integral to the modern world, the study of chemistry can lead to a diverse variety of careers. These include research and development jobs in environmental, materials or forensics chemistry, energy production, biotechnology and medicinal chemistry, and the food, cosmetic and textile industries as well as employment in sales, management, law and consulting.

Computer Science

Computer Science

Computer science emerges from the interaction of two powerful kinds of machines: computers and the human brain. Computer scientists are inventive, innovative, collaborative thinkers creating software solutions and synergies on the cutting edge of technology. The Information Age is here; computer scientists are shaping it.

Ecology & Evolutionary Biology

Ecology & Evolutionary Biology

Ecology and Evolutionary Biology (EEB) deals with the integration of biological systems across all levels of organization, from molecules within cells up through global ecosystems. As such, the department covers a very wide range of topics, from the genetic analysis of complex traits, evolution at the molecular level, phylogenetic analysis, organismal form and function, population and community ecology, genomics, and mathematical modeling.

Geosciences

Geosciences

Geologists study the Earth. We look at the Earth’s origins and how it has changed, and continues to change, over time. We study all of the Earth’s components, from its core to the highest mountains and from its thousands of different minerals to its interaction with the rest of our solar system. UA Geosciences students and faculty are involved in everything from predicting earthquakes to finding and extracting minerals from mines to monitoring coral reefs. We even have a project on Mars!

Mathematics

Mathematics

The mathematics department offers degrees in two different majors: Mathematics and Statistics & Data Science (SDS). Our programs allow the student to choose a major and emphasis that best suit the individual's talents, interests, and career goals. A student may prepare for a variety of careers by selecting the appropriate degree, major, emphasis, and minor. Students choosing a mathematics or SDS major can take advantage of the full range of mathematical resources available on campus.
