Dhanushkodi Mariappan selected to participate in the NAE Symposium

Later this month, the mechanical engineer from GE Research Dhanushkodi Mariappan will join 83 other hand-picked early-career engineers for the National Academy of Engineering (NAE) The Grainger Foundation Frontiers of Engineering 2022 Symposium.

The four themes of the symposium are: 1) microbes: the good, the bad and the ugly; 2) conversational artificial intelligence; 3) technology and racial justice and equity; and 4) hydrogen: a new “universal” energy carrier for a carbon-free future.

“I am delighted to meet with this group from industry, academia and government,” Dhanush said. “Of the four themes, hydrogen is of particular interest to me and part of my work at GE. I look forward to discussions, learning what issues people are working on, and exploring and creating opportunities for partnerships.

Dhanush completed a summer internship at GE through the Massachusetts Institute of Technology (MIT) International Science and Technology Initiatives (MISTI); he joined GE Research full-time in 2004 after earning a master’s degree in mechanical engineering from MIT in his home country of India. He spent two years in research working on electromechanical system design and product development.

Self-taught, Dhanush’s next step was entrepreneurship. He and a team formed an engineered products company focused on creating mechatronics and software solutions for product performance, durability testing, virtual prototyping, and vibration analysis for the automotive and aerospace industries.

In 2015, after a successful exit from his startup, Dhanush returned to MIT to work on his doctoral dissertation, then joined GE Research at Niskayuna in 2019 upon completion of his doctorate. Today, Dhanush works in the Mechanical Materials and Systems organization within the Mechanical Components and Systems team. His recent/current work focuses on three technologies/programs:

superconducting generator: GE Research is integrating superconducting magnets – typically used in particle accelerators for fundamental physics studies and magnetic resonance imaging (MRI) scanners – into offshore wind turbines. These magnets promise more power in a smaller, lighter package. Find out how it works. Dhanush worked on various aspects of the mechanical design of the field coil assembly to meet structural, thermal and electromagnetic specifications.

hydrogen plane – Dhanush is using its expertise to tackle the design of a viable onboard hydrogen storage solution. He is excited to further explore the world of hydrogen at the NAE Symposium as GE’s work in this area progresses.

Printed electronics – Dhanush is part of GE’s efforts to advance the design and manufacture of 2D and 3D printed electronics (sensors) to facilitate inspection and preventive maintenance of critical assets. He is involved in sensor design and testing focusing on the mechanical aspects of sensor design including sensing parameters, material selection, adhesion, performance, durability testing protocols, etc

“The ability to envision what is not yet possible, to create solutions to today’s problems that will benefit all of society in the future, and to be open, inclusive and diverse in our thinking and our abilities and those of others – these are the characteristics of exceptional engineers,” NAE President John L. Anderson said in the NAE press release. the Grainger Foundation helps foster this collaborative spirit among young engineers based in the United States by bringing together a diverse group of different technical fields and work sectors to stimulate innovation, broaden their perspectives on new approaches to engineering problems and develop long-term, long-term relationships that are essential to advancing our nation’s future.

Participants for the next NAE symposium were hand-selected based on nominations from other engineers or organizations. Congratulations, Dhanush!


In addition to the Grainger Foundation, sponsors for the 2022 U.S. Symposium include Amazon, the National Science Foundation, the Air Force Office of Scientific Research, Office of the Undersecretary of Defense for Research and Engineering, and Cummins . Read more.
