Two HEMI Students Receive Alex Charters Student Award from Hypervelocity Impact Society

Congratulations to PhD candidates Debjoy Mallick (Dept. of Mechanical Engineering) and Gary Simpson (Dept. of Mechanical Engineering) for receiving the Alex Charters Student Scholar Award from the Hypervelocity Impact Society!

Students are selected through a competitive evaluation of nominations submitted by their academic advisors. Receiving the award makes them eligible for reimbursement of travel and accommodation expenses to attend the 2019 Hypervelocity Impact Society Symposium. This year, the event will be  held April 14-19, 2019 in Destin, Florida.

This is the second time Mallick has received the Award. The first instance was in 2017.

Prof. Paulette Clancy from the Department of Chemical and Biomolecular Engineering Joins HEMI

Please join us in welcoming the newest HEMI Fellow, Prof. Paulette Clancy! Prof. Clancy is the head of the Department of Chemical and Biomolecular Engineering. She studies the modeling and simulation of semiconductor materials ranging from traditional silicon-based compounds to all organic materials.

As the former Director of the School of Chemical and Biomolecular Engineering at Cornell University, Clancy was the first female director of the school and the first woman to chair an engineering department in Cornell’s College of Engineering. Professor Clancy joined ChemBE as Department Head on Aug. 1, 2018.

Welcome to HEMI, Prof. Clancy!

 

Prof. Somnath Ghosh Recognized by Three Professional Societies

Congratulations to Prof. Somnath Ghosh, HEMI Fellow and M. G. Callas Chair Professor in the Department of Civil Engineering, on receiving significant recognition from three professional societies: the American Society of Mechanical Engineers (ASME), the Society of Engineering Science (SES), and the International Conference on Computational Methods (ICCM). 
 
ASME has awarded him the 2019 Ted Belytschko Applied Mechanics Award, which is given to an outstanding individual for significant contributions in the practice of engineering mechanics, and he will be officially recognized at ASME’s International Mechanical Engineering Conference and Exposition in Salt Lake City in mid-November 2019.
 
He has also been elected as an SES Fellow, which recognizes outstanding individuals for significant contributions in the practice of engineering mechanics; contributions may result from innovation, research, design, leadership or education. He will be honored during SES’s 56th Annual Technical Meeting in St. Louis in October 2019.
 
Finally, the ICCM awarded him the International Computational Method Medal at their international conference in Rome, Italy, last August.
 
We are very proud of the great work being done by Prof. Ghosh.

Building Better Vehicle Armor

The average soldier carries at least 60 pounds of gear, with some specialized fighters carrying loads almost twice that weight. A significant portion of this is body armor. Typically made of a combination of ceramic and polymer materials, body armor worn by infantry members weighs  about 30 pounds.

This equipment is critical for the job, shielding vital organs from the potentially lethal shock of bullets and other projectiles. But even though modern body armor works pretty well for what it’s intended to do, explains Beatriz Medeiros, a third-year materials science and engineering student at the Whiting School, it can be cumbersome.

To lighten soldiers’ loads and to improve their protection within military vehicles, Medeiros is working in the lab of Timothy Weihs, a professor in her department, to develop new types of vehicle armor materials. She recently received the prestigious Undergraduate Research Apprenticeship Program internship, which is co-sponsored by the Army Research Office and the Center for Materials in Extreme Dynamic Environments (CMEDE). CMEDE is the Army’s largest, basic research program focused on improving protection materials for military applications and is located within the Hopkins Extreme Materials Institute. Together, these sources provided the financial support that made it possible for her to continue her research at Johns Hopkins over the summer.

Medeiros is working to produces an alloy which, after proper thermomechanical processing, can form nano-precipitates that can slow down or block dislocations, the atomic-scale defects in materials that are produced and then propagate upon impact.

“A soldier’s job is hard enough,” Medeiros says. “By improving their armor, we’re hoping to make their jobs a little bit easier.”To further strengthen these alloys, Medeiros, under the mentorship of graduate student Suhas Eswarappa Prameela, is exploring different thermomechanical processing methods. These include rolling, which presses the material between two rollers, and equal channel angular extrusion, which pulls it through an L-shaped chamber. Both methods can change the material’s average crystal grain size  and precipitate size, which in turn affects its strength.

HEMI Adds Andrew Proulx as Grants & Contracts Analyst

We are pleased to welcome Andrew Proulx to the HEMI team as our Grants and Contracts Analyst!  Andrew comes to us from his former position as a Financial Representative/Relationship Banker with M&T Bank. A 2013 graduate from Towson University, majoring in Economics with a minor in Business Administration, Andrew began his career at JHU in 2017. Before taking up his newest position, Andrew worked in various positions at Hopkins, including at the Office of Internal Audits, the JHU Research Administration, and at Sponsored Project Shared Services.

Andrew will oversee funds management, including proposing and submitting budgets, account oversight, and billing. He will manage a variety of grants and contracts, and work to ensure that everything funding-wise runs smoothly.

 

Prof. June Wicks Selected as HEMI Seed Grant Recipient

Congratulations to the recipient of the 2018 HEMI Seed Grant, Prof. June Wicks!

Professor Wicks is an Assistant Professor in the Earth and Planetary Sciences Department. Research interests include planetary interiors and evolution; building equation of state and phase diagram models of matter at extreme conditions; kinetics of phase transitions at extreme conditions. In addition to funding her project “Bridging Accessible Strain Rates in the Lab to Recreate Meteorite Impacts”, she will be using the grant to expand the capabilities of her research group.

The HEMI seed grants are given each year to fund research in fundamental science associated with materials and structures under extreme conditions. All faculty and researchers at the Johns Hopkins University, as well as Applied Physics Laboratory (APL) Staff, who can serve as Principal and Co-Investigators are eligible to apply.

HEMI Graduate Student Jason Parker Receives American Society for Composites PhD Scholarship

Congratulations to Jason Parker, a PhD candidate in the Department of Mechanical Engineering, who is one of this year’s recipient of the American Society for Composites (ASC) PhD Scholarship!

First awarded in 2000, the annual graduate student research scholarship grant program was created for formally enrolled Ph.D. students in engineering or science whose dissertation research is focused on some aspect of composite materials. Up to four awards will be given, each consisting of two parts – one portion to support the student’s research and the other to register and attend the ASC Technical Conference.

Parker accepted his award at the ASC banquet on September 25, 2018 at the ASC Technical Conference in Seattle, Washington.
