PROTECT visiting scholar completes tenure at NU

Farewell-Jie-300x225Dr. Jie Peng, Associate Professor of Geotechnical Engineering at Hohai University in Nanjing, China, recently completed his tenure as a visiting scholar with the PROTECT Center at Northeastern University. Under the guidance of Professor Akram Alshawabkeh (Project 5), Dr. Peng assisted in developing and conducting experiments on the fate and transport of contaminants in soil and its impact on soil physicochemical and geotechnical properties. We thank Jie for all of his contributions during his time in the states and look forward to continued collaboration in the future.

Alshawabkeh receives prestigious ASCE award

Dr. Akram Alshawabkeh, along with Dr. Mishac Yegian, Ece Esellar-Bayat, and Seda Goyker, has been awarded the 2014 ASCE Thomas A. Middlebrooks Award for the group’s research on liquefaction mitigation by Induced Partial Saturation (IPS). The award, based on nominations put forward by the Geo-Institute of ASCE, recognizes a paper contributing to geotechnical engineering. This is a prestigious ASCE award within the field of geotechnical and geoenvironmental engineering, with a distinguished list of prior award winners. Congratulations to Professor Alshawabkeh and colleagues!

Local students, teachers perform research in Alshawabkeh lab

Akram Alshawabkeh hosted local high school students and a teacher as part of Northeastern Center for STEM Education’s summer programming through the PROTECT Center.  The month-long program gives opportunities for hands-on research.  This year, Dr. Alshawabkeh hosted Rocco Cieri, a teacher from Medford High School, as part of the Research Experiences for Teachers (RET) program, and  Diana Abbas, a student at Commonwealth School, and Michael Wagner, a student at Belmont High School, as part of the Young Scholars Program (YSP).  The three worked closely with PROTECT Project 5 trainees, particularly postdoc Lily Rajic.  Pictures from their time at Northeastern are below, as well as a video prepared by Rocco Cieri.

Alshawabkeh work profiled in NIEHS SRP Research Brief

Akram Alshawabkeh and his PROTECT Project 5 team recently saw their work in novel methods for groundwater decontamination published by the Superfund Research Program as part of its Research Briefs series.

The Research Brief, published in July, highlights a recent paper by the Project 5 team which developed a method to remediate TCE.

Changes to Alshawabkeh Lab Team

Alshawabkeh Lab Postdocs Dr. Chris Butscher and Dr. Xuhui Mao have both recently secured professorships in their respective home countries of Germany and China.  Dr. Butscher will be at the Karlsruhe Institute of Technology.  Dr. Mao is at Wuhan University.  Congratulations!!

Visiting Scholar Kitae Baek also recently returned to his home country of Korea.

Songhu Yuan joins Alshawabkeh Team

Dr. Songhu Yuan from  State Key Lab of Biogeology and Environmental Geology, China University of Geosciences in Wuhan, China has recently joined the Alshawabkeh research team as a visiting assistant professor for one year.

Dr. Yuan’s expertise is in electrochemical remediation of wastewaters, soils and groundwaters, zerovalent iron remediation and adsorption/desorption.   During his time at Northeastern,

Dr. Yuan will investigate the Pd-based indirect electrochemical oxidation/reduction of TCE in groundwater.

Welcome Songhu!

Preventing Ground Failure Due to Earthquakes

 

Professors Mishac Yegian and Akram Alshawabkeh were awarded a $1.2M NSF grant from the George E. Brown, Jr. Network for Earthquake Engineering Simulation (NEES) to use Induced Partial Saturation (IPS) to try and prevent ground liquefaction from occurring under structures during earthquakes. The goals of this research are to conduct fundamental research exploring the feasibility of inducing partial saturation under field conditions, and to demonstrate the effectiveness of IPS in preventing the occurrence of liquefaction. The outcome of this research will have significant impact on human safety and protection of property from earthquake hazards.
