Research
Through cutting-edge research, faculty in the Department of Physics, Astronomy, and Geosciences contribute to the latest developments in scientific discoveries and integrate their findings into their classrooms.
PAGS faculty encourge student involvement in research and collaboration across departments and agencies outside of TU.
Student Research
Faculty in PAGS strongly encourage students to become involved in some form of experiential learning as part of their educational program.
This can take the form of:
- research with faculty at TU
- participating in summer research programs at other institutions
- involvement in internships
Students find these experiences transformational, motivating and influential regarding career decisions.
Connect with a PAGS faculty member about how you can get involved.
Collaboration
Faculty in the Department of Physics, Astronomy, and Geosciences have expertise in all the fields of astronomy, geology, physics and science education. Additionally, the newly constructed Science Complex houses many instructional and research labs equipped with the latest state-of-the-art technology.
The department welcomes collaborations with outside institutions and agencies who wish to partner on research projects. For more information, please contact the department office (410-704-3020, pags AT_TOWSON).
