Administrative Experience/Highlights

Chair, Department of Mathematics and Statistics, Texas Tech University (6/1999-9/2009).

The Department of Mathematics and Statistics, with 47 tenured/tenure track faculty, 94 full time graduate teaching assistants and approximately 20 instructors and lecturers, teaches more student credit hours than any department at Texas Tech University.  The department teaches approximately 58,000 student credit hours in an academic year of which 3,300 are graduate hours.

From fall 1999 to 2008, the number of graduate students in mathematics and statistics increased by 30% and the number of doctoral students more than doubled.  During the past five-years the department has awarded 32 PhDs and 121 masters degrees.

The department had 170 undergraduate majors in fall 2007 compared to 120 in 2000, and has awarded an average of 40 bachelor degrees for the past five years.

In 2007 the department, with a grant from the National Science Foundation, established the South Plains Mathematics Scholars Program (SPMSP) to support academically talented students from low-income families by providing scholarships for undergraduate study leading to a degree in mathematics.  The inaugural class of 12 SPMSP scholars enrolled at Texas Tech for the fall 2008 semester and receive nearly full

In 2008 the Department of Mathematics and Statistic, in collaboration with the Department of Chemistry and Biochemistry, was awarded two National Science Foundation grants that will enhance graduate and undergraduate enrollment.  A G-K12 Fellowship grant of $2.7 million dollars will provide fellowships of $30,000 to doctoral-level graduate students who will partner with in-service secondary teachers to enhance interdisciplinary educational experiences for mathematics, engineering, and science teachers.  A grant of $740,00 will provide $20,000 stipends to Texas Tech Noyce Scholars who will be seeking teaching certification in mathematics and chemistry.

The number of departmental scholarship endowments has increased from 21 in 1999 to 28 while the total amount of the endowments has grown from $680,000 to more than $1.8 million.  From these endowments the department now awards approximately $200,000 a year in undergraduate and graduate scholarships.

In 2006, the department was awarded the statewide Collegiate Partnership in Education Crystal Award by the Texas Association of Partners in Education, in recognition of outreach to K-12 schools.

Since fiscal year 2000, the department has averaged than $849,456 per year in external funding.  For fiscal year 2008 the department received a record amount of funding of $1,543,853. 

The first endowed chair in Mathematics and Statistics, the “Dick” and Martha Brooks Endowed Professorship, was established in 2004 and successfully filled in 2006.
