Physicists study and uncover the fundamental rules of why and how things work, from quarks to galaxies. Physicists have uncovered some really weird and unexpected things about nature. But applying these principles of physics has transformed the way we interact with the world. Physics concepts are in action all around us — in computer chips, headphones, air bags, and many other everyday devices. It has also made a major impact in healthcare with medical diagnostics and treatments like MRIs and radiation therapy.

Areas of study

Applied Emphasis

The applied emphasis gives you theoretical background to focus on the experimental aspect of physics. While not an engineering degree, this emphasis requires the same basic classes as the Bachelor of Science in Physics & Bachelor of Science in Engineering Dual Degree Program.

Astronomy Emphasis

The science of astronomy applies principles of physics to everything beyond Earth’s atmosphere. Students use what they learn in core classical and modern physics courses to study the properties of stars, planets and exoplanets, white dwarfs, neutron stars, black holes, other galaxies, dark matter, dark energy, and cosmology.

Biomedical Concentration

Do you like physics, mathematics, chemistry, and biology? Are you struggling to choose just one for a major? You don’t have to with the biomedical concentration! This physics concentration combines all of these subjects by providing a set of core courses and allowing you to choose the advanced courses you will take to prepare for your future. Whether you are looking ahead to the rigors of medical school, a program in medical physics, a future in biomedical engineering or other options, a biomedical concentration could be the perfect path for you.

Business Concentration

Combine physics with business to grow your problem-solving skills while expanding your background in business including economics, accounting, finance and marketing. This concentration requires the physics core courses and provides the flexibility to choose from 12 additional physics classes from a catalog of classes. The rest of the classes are taught in the College of Business Administration.

Science Education

Completion of the physics: science education concentration program and associated benchmark assessments will lead to endorsement for the Wisconsin teaching license in middle and high school science, grades 4-12 (2600). Students in all teacher education programs must satisfy the School of Education (SOE) core requirements.

Optics Emphasis

From lasers and light-emitting diodes (LEDs) to fiberoptics, microscopes, spectrometers and telescopes, optical instruments play a key role in how we live and study the universe around us. In this emphasis, students take specialized optics courses where they learn about the fundamental properties of light and how modern optical instruments work.

My time conducting nuclear physics research within the UWL Physics Department opened my eyes to exciting projects and career paths that physics can bring. I would not have made my commitment to pursue nuclear science had it not been for my undergraduate advisor, Dr. Shelly Lesher, and the rest of the faculty in the department.

As an international student from Hong Kong, my experience in the Physics Department was amazing. I enjoyed doing undergraduate astronomy research with Dr. Sallmen. I appreciated all the mentorship, academic and work opportunities provided by faculty, as well as the clubs and events that widened my horizons.

In the UW-L Physics program, the McNair Scholars Program and Dr. Shelly Lesher prepared me for graduate school. While the McNair Scholar program provided workshops to understanding the graduate school process, Dr. Lesher provided the experience I gained from working alongside her that assured my decision to become a nuclear physicist.
