Welcome to the School of Natural Sciences at ϲʿ’s University.

In keeping with ϲʿ’s Holy Cross mission, we educate the hearts and minds of aspiring scientists, equipping them with the knowledge and experience to tackle difficult problems, grapple with the moral and ethical implications of their work, communicate effectively with broad audiences, and help ensure that scientific progress benefits the whole of humanity and not just a select few.

Comprising six departments, we offer courses in astronomy, bioinformatics, biology, chemistry, computer science, forensic science, general science, kinesiology, mathematics, and physics. Most of our classes and labs take place in the John Brooks Williams Natural Sciences Center — two of the newest academic buildings on campus, built specifically for the needs of science in the 21st century. With our facilities and focus on undergraduate education, we are able to offer unparalleled student research opportunities. Many of our students present their work on campus and at local, regional, and national conferences, often winning awards recognizing the quality of their research projects. Our faculty are innovative teachers and leaders in their fields, dedicated to the success of all students.

The School of Natural Sciences offers more than 30 undergraduate major, minor, and certificate programs, including the new BS in environmental biology and climate change, a certificate in data analysis, and minors in bioinformatics, fitness and conditioning, and recreation management. Our BA in health systems & administration provides an opportunity for working healthcare professionals to complete a bachelor's degree and open doors for leadership roles in their fields. In addition, our partnerships with other universities throughout the U.S. allow students to build on their ϲʿ’s education and earn two degrees in five years—one from SEU and one from the partner institution—with guaranteed admission and financial aid for those who qualify. Examples include multiple engineering programs at ,clinical laboratory science at UTMB, and the ESTEEM program in entrepreneurship at Notre Dame.

Our NSF-funded Institute for Interdisciplinary Science (i4) was established to build capacity in interdisciplinary sciences, informatics, and emerging technologies as we increase students’ readiness for the 4th Industrial Revolution. Paid summer internships are among the opportunities i4 makes available for our students.

We also operate the Wild Basin Creative Research Center and manage the 227-acre Wild Basin Wilderness Preserve, located a short drive from campus. Faculty, staff, volunteers, and the public have direct access to Wild Basin, a small piece of and gateway to the 30,000+ acre Balcones Canyonlands Preserve.

The past few years have brought many challenges,but the School of Natural Sciences remains a vibrant and inclusive community of learners, teachers, scholars, and professionals. We are preparing the next generation of scientists to meet these challenges in the pursuit of a more just world. Please don’t hesitate to reach out to me if you have questions or would like to learn more.
