Why Texas State (TxState)?

  • According to CSRankings, in the area of HPC alone, TxState ranks among the top 40 universities in the nation. We are one of the few institutions to have a petaflop supercomputer on-premise and have easy access to the TACC supercomputers.

  • TxState is a large public university (~40K students) located in San Marcos, just 30 miles south of the heart of Austin, TX. Austin is a vibrant city bustling with diversity in food, people, and culture. Being so close to Austin, you will have access to the city's many perks and amenities while enjoying affordable living in San Marcos. Added bonus: almost every single large company (e.g., Google, Amazon, Apple, Meta, AMD, NXP, Samsung) has an office in Austin, so opportunities for jobs and internships are aplenty. 

  • TxState is committed to providing resources and support for a diverse student body. Everyone fits right in!
