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.

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.

Big data is changing the world. Offered through the Department of Mathematics, this degree in Data Science prepares you to take part in the data revolution. Students earning a Bachelor of Science or Bachelor of Arts in Data Science will have a solid foundation in mathematics. Yet they focus on the capture, maintenance, processing, analysis and communication of data through immersion in courses in probability, statistics, data science and computer programming.

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.

Geoscientists 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; 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.

Students in Geosciences and Society will be uniquely qualified to lead in careers that promote and communicate an understanding urgent issues such as protecting water resources, natural hazards to communities, degradation of important biomes, and the impacts of climate change, from the geoscientist perspective. Offered with an emphasis in Law; Public Policy; and Science Communication.

The Hydrology and Atmospheric Science major provides students with a fundamental knowledge of the water cycle, from below the Earth's surface to above Earth's surface, in both theory and application. Students in the HAS major choose a subplan of either Environmental Hydrology and Water Resources or Atmospheric Sciences. 

The Mathematics program 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.

University of Arizona Molecular and Cellular Biology students learn cutting edge biology through innovative teaching methods and hands-on research experiences. The MCB degree provides students the strong foundation in genetics, development, and biotechnology they need to pursue careers in medicine and other health care fields, pharmaceutical and biology research, and education. 

The Department of Neuroscience offers a minor and a major (B.S.) in Neuroscience (NSCI). The NSCI major is tailored to students desiring contemporary in-depth knowledge of how neural circuits function from a molecular, cellular, and systems perspective and how disease processes compromise their performance. Students will also gain experience in laboratory research, with the requirement of at least one semester of research experience.

The Neuroscience & Cognitive Science program is designed on a strong foundation in the basic sciences, in psychology and philosophy, and in mathematics.
