Kaveh Research Group 

My research is primarily in the areas of statistical signal processing, communications, and image processing. My students and I are especially interested in problems of wireless communications using multiple antennas, sensor array signal processing, image enhancement and restoration.

An example of our work in signal processing is the development of algorithms for antenna arrays for…

Poerschke's research seeks to understand the evolution of materials in complex chemical, thermal, and mechanical environments. Combining experimental observations with theoretical models, he develops design-performance frameworks to accelerate the development of new materials offering improved performance. His past efforts have lead to the development of improved ceramic coatings for use in jet engines and provided new understanding of the life-limiting oxidation processes in ceramic…

Chancellor builds and critically evaluates human-centered artificial intelligence (AI) for high-risk health behaviors in online communities. Using machine learning, she uses digital trace data from millions of interactions on social media to identify high-risk behaviors. At the same time, she critically evaluates these predictive approaches and develops more ethical and compassionate research practices for computer science. She is especially interested in dangerous behaviors like pro-eating…

• Harmonic Analysis, especially Fourier analysis.
• Convex analysis and convex geometry.
• Partial differential equations.

Konstan's work lies broadly in the field of human-computer interaction. Most of the work relates to recommender systems -- personalization software -- and how personalization algorithms can be improved to provide better user experience. He also works more broadly on social computing -- challenges in how technology supports (or fails to support) collaboration and on health applications of technology (particularly web and mobile behavioral interventions for…

• Non-equilibrium plasma physics and chemistry
• Plasma technologies for environmental, chemical, energy, biomedical and decontamination applications
• Plasma-surface interactions
• Plasma diagnostics
• Multiphase plasmas in and in contact with liquids

Zhu-Tian's research seeks to augment human intelligence in everyday activities. He approaches this by studying data visualization, human-computer interactions, augmented/virtual reality, and the broader realm of visual computing. His recent work focuses on enhancing human-data and human-AI interactions in AR environments, with applications in sports, data journalism, education, and biomedicine. Ultimately, his research paves the way towards a vision where human intelligence is seamlessly…

Polymer structure and dynamics, self-assembly

We are pursuing a molecular-level understanding of polymer structure and dynamics. Currently, we are most interested in multicomponent systems -- copolymers, homopolymer blends, and their mixtures -- in solution and in the bulk state. Such materials are of great commercial interest, due primarily to the potential flexibility for tailoring superior combinations of physical properties. The overall scientific challenge is to understand how the…

• Stochastic engineering dynamics and mechanics
• Uncertainty quantification for complex systems
• Structural reliability
• Risk based optimization
• Signal processing for stochastic systems

Dr. Arndt is a Professor Emeritus, University of Minnesota. His major research interests are in the area of fluid mechanics with emphasis on turbulent shear flows and vortex flows; cavitation; aeroacoustics including jet noise and turbomachinery noise; alternate energy with an emphasis on hydropower and wind turbine technology; and aeration technology with a view towards developing cost effective environmental remediation techniques. His research experience includes cavitation in pumps,…
