Hubler Research Group

Dr. Hubler’s research group addresses construction material design for structures under unique loading conditions and for improved lifetime. The overarching goal of our research is to develop the means to create metamaterials which capitalize on valuable fracture, fragmentation, and energy dissipation mechanics behaviors seen in rock, concrete, and colloidal structures. In pursuit of this goal, current work aims to build a better understanding of the mechanics of random multiscale materials through experimental and analytical methods. Ongoing research involves the design of cementitious materials, micro-structure quantification, carbon sequestration, electromagnetic shielding, fracture mechanics, micro- and meso-scale testing, energy dissipation, creep, and dynamic fragmentation.

Regueiro Research Group


Ren Research Group

The Ren group develops and applies novel materials for energy and environmental applications. We develop materials from wood, fungal, algal, and bacterial biomass for renewable energy production and storage, water and wastewater treatment, water desalination, carbon capture and utilization, and commodity chemical production. We also develop reactors to characterize and optimize different materials such as electrodes, catalysts, membranes and resins for system scale-up and engineering applications. The group conducts interdisciplinary research with collaborations with many labs at CU, NREL and other institutions. Current projects are funded by NSF, ONR, DOE, and Industry for microbial electrochemical energy production, electrochemical energy storage, microbial electrosynthesis, carbon capture and utilization, membrane bioreactors, and energy-positive wastewater treatment and desalination.

Song Research Group

Computational material engineering for metal alloy system and polymer composites. We focus on developing computational framework to provide a predictive computational infrastructure for optimizing material design/manufacturing processes in a manner that ensures the performance of the relevant macroscopic products on demand. As a key to tailor and enhance the mechanical performance of the final products in macro scale, multiphysics phenomena involved in the microstructure evolution are predicted and subsequently up-scaled to macro scale through a coupled computational multiscale/multiphysics analysis approach. Some of our current research topics include, but not limited to: (1) Developing physics-based computational analysis methods to investigate material behaviors in micro (atomistic)/meso (quasi-continuum)/macro (continuum) length scales; (2) Developing computational predictive framework to identify the relation between 3D metal printing process parameters and the mechanical response of the final products; and (3) Developing multiscale/multiphysics Integrated tool to predict manufacturing-induced defects in autoclave polymer composites through coupled chemo-mechanical analysis.

Srubar Research Group

The Srubar Research Group focuses on polymer- and cement-based infrastructure materials for sustainable infrastructure applications. Materials of current focus include (1) low-calcium alkali-activated (geopolymer) cements, (2) bioaerogels, (3) superabsorbent biopolymers, (4) natural fiber composites, (5) engineered wood products, and (6) ordinary portland cement concrete. We focus our experimental efforts on elucidating fundamental process-structure-property relationships, carbon sequestration, and long-term durability and our computational efforts on transport phenomena, service-life modeling, life cycle assessment, and energy simulation of buildings. Our current work is supported by the National Science Foundation, Industry, and the University of Colorado. Website: http://spot.colorado.edu/~wisr7047/
