### Department Faculty

## The Mathematics Program

The interests and expertise of the mathematics faculty cover a broad range of mathematical areas, including algebra, analysis, topology (modern geometry), discrete mathematics (mathematics of computer science), number theory, statistics, and applied mathematics. With this spectrum of faculty knowledge, the student is afforded an opportunity to learn the contemporary view of mathematics. Inside the classroom, student comprehension is the main concern of the faculty. Outside the classroom, the faculty offers opportunities for independent study, undergraduate research, and internship supervision.

Courses in mathematics vary from the theoretical to the applied. Thus, a Bachelor of Science degree in Mathematics can be a foundation for a career in industry, government, teaching, or the pursuit of a higher degree in graduate school. The department faculty encourages double majors, giving students entrance to a wide variety of fields upon graduation. Majors in other disciplines can be enhanced with one of our minors in mathematics, applied mathematics, or actuarial science.

The University of Mary Washington hosts a chapter of Pi Mu Epsilon, a national honorary mathematics society, and a chapter of the Mathematical Association of America. The Oscar Schultz Award in Mathematics represents the department’s top academic honor and is given annually to a junior or senior in the department. Four additional scholarships are available. The recipients of the Meredith C. Loughran ’94 Scholarship are selected based on their meritorious academic record, citizenship and leadership in public service. The Merrilyn Sawyer Dodson/class of 1968 Scholarship and the Mary Farley Talley ’66 Scholarship each recognize the scholastic achievements of mathematics majors, while the Louise W. Robertson, M.D. ’56 Scholarship is awarded to a student majoring in mathematics or a health field.

Qualified mathematics majors having at least a 3.5 GPA in mathematics courses and an overall GPA of at least 3.0 may graduate with Honors in Mathematics by completing a directed study or undergraduate research which culminates in an approved Honors thesis.

Majors are encouraged to fulfill the general education experiential learning requirement by completing URES 197, MATH 491, MATH 492, or MATH 499. Alternatively, majors may meet this requirement by participating in an approved supervised on-campus or off-campus experiential learning activity developed in consultation with the department (such as the UMW Summer Science Institute or a similar program at another college or university). To complete the experiential learning requirement through a summer research experience, contact the department chair for more details.

## Requirements for the Mathematics Major

A minimum of thirty-eight (38) credits are required. Twenty-three (23) credits must be from the following mathematics courses: MATH 122, 224, 300, 330, 431, 471 and either 432 or 472. An additional twelve (12) credits must be taken from MATH or STAT courses at the 300-/400-level with at least three (3) credits from 400-level MATH or STAT courses. Three (3) additional credits must be from MATH or STAT courses numbered 207 or above; computer science (CPSC) courses numbered 220 or above (except CPSC 302); physics (PHYS) courses numbered 105 or above (except PHYS 108); or PHIL 306. Mathematics majors must meet the department’s computer programming requirement by taking one of the following courses: MATH 351, 421, CPSC 110, 219, or 220. Courses used to satisfy the programming requirement may also be used elsewhere in the major. At most six (6) credits of directed study (MATH or STAT 491/492) will count for the major. No internship (MATH or STAT 499) credits will count for the major.
