THE SIMON AND CLAIRE BENSON AWARD

The most prestigious undergraduate student award given by CEGE, the Simon and Claire Benson Award, recognizes outstanding undergraduate performance. The award was established in memory of two former CEGE students who were killed in a car accident. This year, in an unprecedented move, the committee decided to give two awards. Stefano Gonella, Chair of the Awards Committee, announced the awards saying, “This year, we have two ex-aequo (equally placed) Benson award winners: Marhta Burket and Anne Tuttle. Both these students deeply impressed us, with their records, their determination, and their demeanor during their interview. Both winners graduated with degrees in Environmental Engineering. Each embodies a distinct, personal path towards excellence.”

MARTHA BURKET's performance was impeccable throughout her studies. What most impressed the Committee was her inquisitive, curious, and creative mindset. She was involved with research in a number of labs, most notably in the past couple of years working under the guidance of Prof. Leif Olmanson (Forest Resources) in the area of remote sensing of water resources. There she compared methodologies for remote sensing of water color as an indicator of chemical and biological activity in the water.

ANNE TUTTLE was involved with research in Prof. LaPara’s group in the field of wastewater treatment, studying the effects of Minnesota water on the hypoxic zones in the Gulf of Mexico. Her approach to coursework and academics was a constant statement of determination and hard work, which led her to excellent academic results, but, more importantly, to the development of a sincere and thoughtful passion for environmental science and engineering. The Committee was impressed by the maturity of her reflection on her academic path and by her ability to work through challenges, progressively leading to a stronger and stronger connection with her field of study.

FACULTY NEWS

PAUL CAPEL hosted a group of nine scientists from Brazil and Paraguay in August 2022, as part of an international cooperation with the U.S. Geological Survey. The visiting scientists represented the Brazilian Federal University for Latin American Integration (UNILA) and Itaipu Binacional, a bi-national hydropower agency and facility that supplies all of the electricity to Paraguay and a major portion of power to Brazil. While in Minnesota, the visiting scientists observed research and teaching laboratories and talked with researchers about issues of soil erosion and transport of sediment, nutrients, and man-made chemicals.

XUE FENG, McKnight Land-Grant Assistant Professor, has received a research award in the amount of $505,165 over three years to study snow hydrology. Salli Dymond (Institute on the Environment) is her co-principal investigator. The researchers propose to look at how forest controls snowpack timing and duration, and how that gets mediated by frost and lateral flow of water. They will use models and field measurements from a catchment in northern Minnesota.

QIZHI HE received a U of M Informatics Institute seed grant award. He and Ju Sun are developing a physics aware machine learning framework to help predict and reduce defects in metal additive manufacturing (3D printing). Their novel, knowledge-augmented, machine learning tool will quickly and reliably predict thermal mechanical behavior and the induced defects by using thermomechanical models and process monitoring data.

MIKI HONDZO was elected to a three- year term on the National Harmful Algal Bloom (HAB) Committee (NHC). The mission of the NHC is to facilitate coordination and communication of activities for the U.S. HAB community at a national level, to provide a collective voice of the academic, management, and stakeholder communities interested in national issues related to harmful algal bloom.

JOHN HOURDOS is part of an Inter- Sections grant project. InterSections is a new research funding initiative by the College of Science and Engineering; its goal is to bring together resources from around the College to encourage intersectional, collaborative research. Hourdos was instrumental in connecting Sarah Swisher from the Department of Electrical and Computer Engineering, Andreas Stein from Chemistry, Philippe Buhlmann also from Chemistry, and Arthur Erdman from Mechanical Engineering. The team will be prototyping a continuously monitoring sensor, so doctors can do some experimentation. And secondly, they will work on creating such a device at the nanoscale. Their goal is to use the InterSections seed funding to demonstrate the feasibility of manufacturing a kind of nano-needle that can measure what is desired, and then to develop a micro-electronic that allows doctors to receive continuous measurements.

ALIREZA KHANI presented his research as part of a panel at the ATA Conference. The panel titled “Recommendations for Developing Charging Station Infrastructure for Commercial Fleet Operations” was picked up in the Transport Topics, a newsletter for the Trucking and Freight Transportation industries (March 21, 2022).

JIA-LIANG LE and JOE LABUZ received $457,000 over three years through an NSF Grant for their project, “Objective Stochastic Modeling of Quasibrittle Damage and Failure Through Mechanistic Mapping of Random Fields.” Understanding stochastic structural response is central to reliability-based engineering designs. Quasibrittle structures can exhibit complicated failure mechanisms governed by varying material length scales. Without considering these length-scale variations when modeling the random constitutive properties, stochastic finite element simulation (a tool widely used to investigate the probabilistic behavior of structures) can be severely limited in its prediction capacity. The goal of this research is to develop a new computational framework for stochastic analysis of quasibrittle damage and fracture. The framework is anchored by a mechanism-based projection of random fields of constitutive properties onto the finite elements. The model will be validated through a unique set of experimental data on the effects of specimen size and geometry on the probabilistic failure of a porous rock. The research will be integrated with educational activities for high-school, undergraduate, and grauate students.

MICHAEL LEVIN recently completed a project with MnDOT that could affect the daily commute for thousands of people. Levin and graduate student Simanta Barman started working on this project in September 2019. They applied a new adaptive method for controlling signal timings, called max-pressure control. The method has been mathematically proven, but its performance was not well-known in practice. Levin and Barman conducted methodological improvements and simulation experiments on a calibrated model of seven intersections in Hennepin County. They found that max-pressure signal timing achieves higher throughput during peak demand and is more responsive to queues.

SONIA MOGILEVSKAYA and JOSEPH LABUZ will represent the geomechanics group in the project titled “Diagonal,” which was recently funded by the European Commission. Diagonal involves a consortium of four European institutions (University Carlos III of Madrid, Spain; University of Seville, Spain; Institute of Fundamental Technological Research, Poland; School for Advanced Studies Lucca, Italy) and six partner universities (University of Florida, USA; Northwestern University, USA; Texas A&M University, USA; University of Minnesota, USA; Monash University, Australia; Universidade Federal de Santa Maria, Brazil). Diagonal will advance the state of the art in flow and fracture of brittle and ductile functionally graded materials through (1) training and knowledge sharing activities and (2) a series of international workshops for doctoral candidates and postdoc- toral researchers from the consortium. The scientific objective is to extend the use of functionally graded materials, including fabrication with additive manufacturing techniques, in the construction of parts designed for critical structural applications in the transportation and security industries.

RAPHAEL STERN is contributing to research on deer-vehicle collisions. “The idea is to identify hot spots and see what might be contributing to these collisions,” said Stern, who is working with MnDOT. The research appeared in the Star Tribune September 19.

JUDY YANG, Assistant Professor in CEGE, has received four substantial research grants. 1) Yang received $110,000 over 2 years through the Doctoral New Investigator (DNI) grants program. She will study “Pore scale investigation of the impacts of swelling clay on oil-brine transport in porous media.” 2) A $553,400 NSF grant through the Hydrological Sciences program will support her project, “Multiscale Experimental and Numerical Investigation of Impacts of Turbulence and Vegetation on Flow and Solute Transport in Hyporheic Zone.” Her co-PI is Peter Kang (Geosciences, UMN). 3) A $326,000 grant from the Legislative-Citizen Commission on Minnesota Resources (LCCMR) was awarded for her project titled “Mitigating Cyanobacterial Blooms and Toxins Using Clay-Algae Flocculation.” She and co-PI Miki Hondzo will investigate solutions to excessive algae growth in Minnesota’s lakes and rivers. 4) She received a second NSF grant in excess of $300,000 for her project “Collaborative Research: Grain to Channel Scale Experimental and Numerical Investigation of Cohesive Sediment Transport.”

YANG also published a new study Geophysical Research Letters, the leading journal in earth science. Said Yang, “I think our work is really transformative and fun. We constructed a transparent wetland out of glass. We tracked the movement of a fluorescent dye, and found that vegetation can increase the exchange of surface and subsurface water because it induces turbulence and spatial heterogeneity/variation in flow. Our results could have a profound impact on understanding and prediction of contaminant transport in wetlands.”  Her work was partially funded by the Minnesota Water Research Fund. Yang also presented, "Seeking to Improve Stream Restoration to Ensure Safe Drinking Water and Fisheries," at an event hosted by the Minnesota Water Research Fund.

Corrections (oops!)

Itasca’s contribution to the project was the neural network, not the sensor. Many thanks to David O. DeGagné for correcting our misstatement. ITASCA INTERNATIONAL, INC., won a MN Tek Award for 2021 in the category of Machine Learning. A local construction company asked Itasca to look into the problem of cranes and similar equipment being prone to toppling when moving over ground of varying deformability. Itasca developed an artificial neural network bundled into a webapp that reads raw data files from in-situ testing equipment and notifies the engineer whether the location is suitable for walking the cranes safely. Dr. Varun, Senior Geomechanics Engineer, and Dr. Jason Furtney, Chief Technical Officer and Senior Engineer, led the effort.

Graduation year correction: ROBERT KRUSSOW (BCE 2004, PE LEED AP) joined 3M as the Facilities Civil Engineer. He provides civil engineering and project management services to 3M facilities in the U.S. and Canada.

Mariette is a civil engineering student in the first year of his Master of Science degree. He had a summer internship in CEGE. Mariette shared this about his experience: "I am very happy that Prof. Marasteanu welcomed me into his research team to work on the evaluation of rheological parameters to predict non-related cracking susceptibility of asphalt binders. It was an American way to approach this topic, and I found it very interesting. It has been rewarding to understand how the research community works here in the United States.”

ADEL SOROUSH, now a postdoctoral Researcher at the University of Illinois Chicago, completed his Ph.D. in 2021, advised by William A. Arnold and R. Lee Penn (Chemistry). His thesis explores “The role of continuous contaminant exposure and natural organic matter on the evolving reactivity of iron oxide nanoparticles.” The findings of this research demonstrated that the reactivity of iron oxide particles evolved during exposure to contaminants, and reactivity depends on the iron oxide phase, hydrodynamics of water flow, and the presence of other environmentally relevant components like natural organic matter. By advancing our understanding of iron oxide reactivity in the subsurface environments, better prediction of the efficacy and optimization of remediation methods are possible.
