CIS Student Being Recognized by CRA Outstanding Undergraduate Researcher Award for 2022

Andy Nguyen, a Junior student pursuing a CS degree at the University of Oregon, has been selected for an Honorable Mention for the Computing Research Association’s (CRA) Outstanding Undergraduate Research Award for 2022 (

The CRA’s Outstanding Undergraduate Research Award recognizes undergraduate students in North American colleges and universities who show outstanding research potential in area of computing research. Andy is the only student from a university in Oregon to have been selected for this prestigious award.

For the past 15 months, Andy has been working with Professor Jee Choi in the CS department on designing a new fast, scalable, and performance-portable algorithm and data structure for calculating sparse tensor factorization on GPUs. Sparse tensors are ubiquitous in many critical real-world applications, such as data mining, social network analysis, cybersecurity, healthcare, and more. His research paper, titled “Efficient, Out-of-Memory Sparse MTTKRP on Massively Parallel Architectures,” presents the very first tensor factorization software that can process extremely large tensor data sets that do not fit in device memory, and demonstrates up to 23.39x faster performance compared to prior state-of-the-art software.

Andy enjoys competitive programming and have participated in the International Collegiate Programming Contest (ICPC). Andy has also recently been invited to present his research at the Society for Industrial and Applied Mathematics (SIAM) Parallel Processing Symposium.
