Civil Engineering Ph.D. to Attend SIAM Conference in Computational Science and Engineering

The new year has only just begun, but one civil engineering Ph.D. student is already planning to pack his bags and hit the road.

Saeid Karimi has received a travel award from the Society of Industrial and Applied Mathematics (SIAM) to attend the 2015 SIAM Conference in Computational Science and Engineering (CSE15). The award includes a registration fee waiver and cash award. Karimi, who’s advisor is civil engineering assistant professor Kalyana Babu Nakshatrala, will be delivering a talk and presenting a poster for student competition at the conference. The title of his talk is “Monolithic multi-time-step coupling methods for transient systems.”

Under this research, funded by the National Science Foundation, robust numerical frameworks have been developed for problems involving multiple mathematical scales, which has been a subject of great interest in computational mathematics and engineering. A systematic theoretical study (e.g., error analysis, stability, propagation of errors) has also been performed on the proposed numerical formulations. The research work provides the much-needed accurate simulation tools for solving multi-scale and multi-physics problems like fluid-structure interaction (e.g., blood flow in deformable arteries), and soil-structure interaction. The research on a multi-time-step method for elastodynamics has been published in the Journal of Computational Physics, and the research on multi-time-step methods for advective-diffusive-reactive systems has appeared in Computer Methods in Applied Mechanics and Engineering.

“I was quite excited to receive the award,” Karimi said. “Some of the past winners have become faculty members or scientists in national laboratories.” He said he’s looking forward to meeting some of the leading figures in computational sciences. “It’s one of the most important gatherings in my research area.” The conference will be held in Salt Lake City, Utah from March 14-18.

What’s in the Water? Hurricane Harvey Renews Attention to UH Research on Galveston Bay Pollutants

In the days after Hurricane Harvey slammed into the Texas Gulf Coast, thousands of evacuated families returned to their homes to survey the flood damage and begin the long road to repairs.

But the dream to rebuild isn’t a realistic one for many families in riverfront neighborhoods east of Houston, where industrial waste from the notorious San Jacinto Waste pits, a Superfund site, may possibly have contaminated the land.

Rigzone: Advice for Geotechnical Engineering Graduates from UH Civil Engineer

Geotechnical engineers toil in the mechanics of soil and rocks to design and build structures, roadways, levees and other systems that are supported by soil or rock. Career opportunities abound for graduates in the geotechnical engineering field, but obtaining certain skillsets in this field can give geotechnical graduates an advantage in landing their dream job.
