Exploring the Tian He UMN Undergraduate Program: A Deep Dive
The University of Minnesota (UMN) offers diverse and innovative undergraduate programs, particularly within the College of Science and Engineering (CSE). Among the distinguished faculty is Tian He, a McKnight Distinguished Land-Grant Professor and an associate professor in the Department of Computer Science and Engineering. This article delves into various aspects of UMN's undergraduate programs, with a focus on the contributions and research areas associated with faculty like Tian He and the broader impact of the Computer Science and Engineering department.
A Legacy of Innovation: Computer Science and Engineering at UMN
The Department of Computer Science and Engineering (CSE) at UMN boasts a rich history, tracing its roots back to the earliest days of computing in Minnesota. Since 1970, the department has evolved from a small group of visionary numerical analysts into a nationally recognized force in computing education, research, and innovation. Over the past half-century, the department has granted over 10,600 undergraduate and graduate degrees, with enrollment figures demonstrating continuous growth.
Tian He's Research and Impact
Tian He's work exemplifies the interdisciplinary approach fostered at UMN. As an IonE resident fellow, Tian He collaborates with faculty from across the University of Minnesota system to address global grand challenges. His research interests include utilizing metropolitan-scale taxi networks for urban pollution monitoring and reduction. Smart vehicles equipped with sensors like GPS, accelerometers, and gyroscopes enable crowd-based sensing, a technique that offers unprecedented flexibility, scale, and resolution in gathering information. Crowd-based sensing has the potential to generate a comprehensive view of phenomena, such as urban traffic patterns, real-time city pollution maps, and the micro-scale monitoring of land use, which was previously difficult or impossible to achieve.
Tian He's previous work focused on improving the efficiency and reducing the cost of public transportation systems, especially taxi networks. He proposed modeling behaviors of urban transportation systems with massive multi-modal online feeds and applying effective local and global cyber-control. His group has investigated the Capital BikeShare system in Washington D.C., using online data feeds provided by Arlington County to identify key control issues, such as imbalanced bike usage leading to faster bike deterioration and high overhead in rebalancing bikes with trucks.
Tian He's extensive publication record showcases his significant contributions to the field. His work includes:

Cutting-Edge Research and Innovation
Beyond the work of individual faculty members like Tian He, UMN's CSE department is actively involved in numerous cutting-edge research projects. Professor Zhi-Li Zhang is the PI on a two-year, $7M project aimed at improving 5G networks to enable autonomous vehicle (AV) teleoperations. The DRIVE-SAFE project is creating teleoperation systems that allow human operators to remotely control AVs in complex situations, such as construction and accident zones.
UMN is also at the forefront of Artificial Intelligence (AI) research and its applications. Assistant Professor Aryan Deshwal won the Innovative Deployed Application Award at the Association for the Advancement of Artificial Intelligence (AAAI) Innovative Applications of Artificial Intelligence (IAAI) Conference. Furthermore, CS&E PhD candidate Sean Dorr is using data visualization tools to foster relationships between Indigenous communities and climate scientists, connecting these communities to their lands, waters, and skies. Xianhao Carton Liu studies human-AI teaming in spatial AR, revealing the trade-off between spatial mapping and AI over-reliance. Chunggi Lee and Hayato Saiki present ViSTAR, an AR coaching agent that turns 3D motion reconstruction + joint kinematics into LLM-generated, kinesiology-style feedback.
The University of Minnesota's commitment to AI is further demonstrated by Professor Kumar's appointment to a 40-member panel providing independent, evidence-based assessments of AI to inform global understanding of its opportunities, risks, and societal impacts.
Undergraduate Research Opportunities
UMN offers numerous opportunities for undergraduate students to engage in research. These opportunities allow students to work alongside faculty members like Tian He and other leading researchers, gaining valuable experience in their fields of interest. Undergraduate research can take many forms, including assisting with ongoing research projects, conducting independent research under the guidance of a faculty mentor, and presenting research findings at conferences and in publications.
