Please answer the following question: Information: - The Mathematical Association of America (MAA) is a professional society that focuses on mathematics accessible at the undergraduate level. Members include university, college, and high school teachers; graduate and undergraduate students; pure and applied mathematicians; computer scientists; statisticians; and many others in academia, government, business, and industry. - A mathematician is someone who uses an extensive knowledge of mathematics in his/her work, typically to solve mathematical problems. - A research university is a university that expects all its tenured and tenure-track faculty to continuously engage in research, as opposed to merely requiring it as a condition of an initial appointment or tenure. Such universities can be recognized by their strong focus on innovative research and the prestige of their brand names. On the one hand, research universities strive to recruit faculty who are the most brilliant minds in their disciplines in the world, and their students enjoy the opportunity to learn from such experts. On the other hand, new students are often disappointed to realize their undergraduate courses at research universities are overly academic and fail to provide vocational training with immediate "real world" applications; but many employers value degrees from research universities because they know that such coursework develops fundamental skills like critical thinking. - A university ("a whole", "a corporation") is an institution of higher (or tertiary) education and research which grants academic degrees in various subjects. Universities typically provide undergraduate education and postgraduate education. - Dallas is a major city in the state of Texas and is the largest urban center of the fourth most populous metropolitan area in the United States. The city proper ranks ninth in the U.S. and third in Texas after Houston and San Antonio. The city's prominence arose from its historical importance as a center for the oil and cotton industries, and its position along numerous railroad lines. The bulk of the city is in Dallas County, of which it is the county seat; however, sections of the city are located in Collin, Denton, Kaufman, and Rockwall counties. According to the 2010 United States Census, the city had a population of 1,197,816. The United States Census Bureau's estimate for the city's population increased to 1,300,092 as of July 1, 2015. - The University of Texas System (UT System) encompasses 14 educational institutions in the U.S. state of Texas, of which eight are academic universities and six are health institutions. The UTSystem is headquartered in Austin, and has a total enrollment of over 216,000 students (largest university system in Texas) and employs more than 87,000 faculty and staff. The UT System's $36 billion endowment (as of May 31, 2016) is the largest of any public university system in the United States. - A statistician is someone who works with theoretical or applied statistics. The profession exists in both the private and public sectors. It is common to combine statistical knowledge with expertise in other subjects, and statisticians may work as employees or as statistical consultants. - The University of Texas at Dallas (UT Dallas or UTD) is a public research university in the University of Texas System. The main campus is in the Richardson, Texas, Telecom Corridor, north of downtown Dallas. The institution, established in 1961 as the Graduate Research Center of the Southwest and later renamed the Southwest Center for Advanced Studies (SCAS), began as a research arm of Texas Instruments. In 1969, the founders bequeathed SCAS to the state of Texas officially creating The University of Texas at Dallas. - The Telecom Corridor is a technology business center in Richardson, Texas, a northern suburb of Dallas, which contains over 25 million square feet (2.3 million square meters) of office space and accounts for over 130,000 jobs. Located in the Dallas/Fort Worth area and home to the University of Texas at Dallas, the Corridor is a strip about long along U.S. Route 75 (US75) (the North Central Expressway), between President George Bush Turnpike and Interstate 635 (I-635) and is often considered an area of the Silicon Prairie. More than 5,700 companies, including 600 technology companies are headquartered in the area, including significant players such as AT&T, Alcatel-Lucent, Ericsson, Verizon, Samsung, Texas Instruments, and MetroPCS. Some of these companies also have offices in Telecom Valley located in California. Although the Telecom Corridor was a booming area of Dallas's economy during the late 1990s, the dot-com bust of 2001 hit the region hard. However, it began recovering in 2004, and that recovery has since picked up momentum, gaining both the operations of many non-technology-related companies and a large number of previously non-existent residential units designed in the New Urbanist style. The name "Telecom Corridor" is a registered trademark and may technically only be used to describe the area mentioned in this article. - A computer scientist is a scientist who has acquired the knowledge of computer science, the study of the theoretical foundations of information and computation and their application. - Titu Andreescu ( born 1956 ) is an associate professor of mathematics at the University of Texas at Dallas . He is also firmly involved in mathematics contests and olympiads , having been the Director of AMC ( as appointed by the Mathematical Association of America ) , Director of MOP , Head Coach of the USA IMO Team and Chairman of the USAMO . He has also authored a large number of books on the topic of problem solving and olympiad style mathematics . - Texas Instruments Inc. (TI) is an American technology company that designs and manufactures semiconductors, which it sells to electronics designers and manufacturers globally. Headquartered in Dallas, Texas, United States, TI is one of the top ten semiconductor companies worldwide, based on sales volume. Texas Instruments's focus is on developing analog chips and embedded processors, which accounts for more than 85% of their revenue.
