HEMI Fellow Somnath Ghosh awarded ASCE’s Raymond D. Mindlin Medal

Somnath Ghosh, HEMI Fellow and Michael G. Callas Chair Professor in the Department of Civil and Systems Engineering, has been awarded the 2022 Raymond D. Mindlin Medal by the American Society of Civil Engineers (ASCE). Given annually, this medal recognizes an individual’s outstanding research contributions to applied solid mechanics.

Somnath was honored for “outstanding novel contributions to the field of computational mechanics of materials through development of fundamental concepts in spatio-temporal multi-scale, multi-physics modeling of metals, composites and multi-functional materials, and bridging the mechanics and materials communities through strong interdisciplinary leadership.”

Somnath’s research focuses on computational engineering and sciences integrating computational mechanics, computational materials science, and integrated computational materials engineering, with an emphasis on multiscale multi-physics modeling, materials characterization, machine learning, and uncertainty quantification.

He has been invited to accept this award in person at ASCE’s annual Engineering Mechanics Institute Conference, to be held in Baltimore from May 31 through June 3.

Tamer Zaki and Jochen Mueller named HEMI Fellows

Prof. Tamer Zaki and Assistant Prof. Jochen Mueller have been appointed as two of the newest HEMI Fellows.

Zaki is currently a professor in the Department of Mechanical Engineering. He is a winner of the Office of Naval Research Young Investigator Award, is recognized for his innovative theoretical and engineering solutions to technological and environmental challenges created when turbulence meets momentum, heat, and mass.

His work offers novel applications for hydro and aero-dynamics, turbo-machinery, heat transfer, materials processing, and medical interventions with inhaled drug delivery. His research and the work of his lab, Johns Hopkins’ Flow Science and Engineering (FSE), address a classic, complex mechanics problem: Infinitesimal disturbances can cause organized fluid motion to become chaotic.

Mueller is an assistant professor in the Department of Civil and Systems Engineering. His research combines additive manufacturing, functional materials, and computational design in order to create programmable matter.

His research lives at the intersection of science, application and design. Developing novel fabrication processes to enhance the structural complexity, material versatility, and throughput speed in 3D printing, Mueller’s Laboratory for Digital Fabrication and Programmable Matter combines the fabrication processes with computational tools to create or manipulate existing materials and structures in order to change their properties and improve their performance. Mueller’s hands-on background in the aerospace and automotive industries allows him to pursue research projects that have real-world applications, improving materials used in everything from prosthetic devices to lightweight structures.

2021 AEOP Apprentices Showcase Their Gained Knowledge in Extreme Science During Final Presentations

Earlier this month, four students from high schools around the state of Maryland presented the results of their summer Apprenticeship Program  virtually to an audience of  friends, family, mentors, HEMI Fellows, and representatives from the U. S. Army – Dr. Sikhanda Satapathy (Collaborative Alliance Manager for MEDE CRA) and Mr. Brian Leftridge (U.S. Army Combat Capabilities Development Command).

Adesola Adelegan, Nahuel Albayrak, Kathy Ho, and Emma Liu each were paired with a HEMI Fellow and student mentor to complete their six-week project. During the presentations, each student summarized their research experience, answered questions, and were virtually awarded with a certificate of completion.

During the course of the presentations, HEMI Fellow hosts and mentors had a chance to reflect on each student’s accomplishments. Across the board, the students were lauded for their work ethic and ability to grasp high-level concepts.

“I’m ready to offer her a graduate position,” said Jaafar El-Awady, HEMI Fellow and associate professor in the Department of Mechanical Engineering, when speaking about his group’s intern, Kathy Ho. “She’s done such great, high-level work.”

Echoing Prof. El-Awady’s sentiments was Mitra Taheri, HEMI Fellow and professor in the Department of Materials Science and Engineering, about her group’s intern, Emma Liu. “Emma is underplaying her role in this project. Her research has moved us forward in the state-of-the-art.”

These apprenticeships, sponsored by the Army Educational Outreach Program (AEOP), allows students to gain valuable research experience before attending college. With over 40 sites from which to choose, Johns Hopkins ranks as a very competitive location. Johns Hopkins University received 185 applications for four positions this year.

HEMI Fellow Thomas Gernay Investigates Construction Applications for New Steels

Using funding from both a HEMI Seed Grant and the National Science Foundation, Thomas Gernay, HEMI Fellow and assistant professor in the Department of Civil Systems and Engineering, and colleague Benjamin Schafer, professor in the same department, are investigating if four new types of high-performance steels used in car parts can be cross-functionally used to construct more resilient and sustainable buildings.

The new steels, developed by the automotive industry and used in car bumpers and the steel cage that protects occupants in a crash, improve car handling and fuel efficiency. They are four times stronger than the steel commonly used today, but they are also more expensive to manufacture. Figuring out how to use these steels efficiently in buildings is a priority and a situation that Schafer and Gernay are trying to address.

Gernay and Schafer compiled a comprehensive data set that provides insight into the steels and how they behave under different conditions. Gernay and his team, experts in fire resiliency, tested the steels to gauge their responses to stress, strain, and high temperatures. Schafer’s research centered on the steels’ properties when formed into shapes optimized and appropriate for building construction.

They are currently entering the materials’ temperature data into Gernay’s SAFIR software, which models the behavior of building structures related to fire. Upon completion, the data and hypothetical scenarios will be available for industry use to compare different steels and determine the best material for individual projects.
