Student researchers at UAH are being encouraged to submit abstracts of 250 words maximum outlining a design and research project relevant to the aerospace industry for consideration for the 7th Wernher von Braun Memorial Symposium coming to UAH Oct. 27-29.

Abstracts should be submitted online at http://www.vbsposters.org by Friday, Sept. 12. Authors will be notified of acceptance by Tuesday, Sept. 16 and an electronic poster template will be provided. Final posters are due by Wednesday, Oct. 15.

Abstracts on atmospheric science, earth observation, space life sciences, space health, aerospace systems engineering and design, astrophysics, space weather, optics, economics, business, policy, sustainability, history, international relations, education, science, STEM outreach initiatives or related areas are requested.

UAH’s first Tech Trek an unqualified success
UAH’s first Tech Trek an unqualified success

MAIN

This July, UAH hosted its first-ever Tech Trek, a weeklong residential camp to promote interest in the science, technology, engineering, and math (STEM) fields among rising eighth-grade girls. And by every measure, says Camp Director Dr. Rhonda Gaede, it proved to be an unqualified success.

"On Sunday, the girls were names on forms to me; by Friday, they were friends that I hated to see go," says Dr. Gaede, who also serves as an associate professor of Electrical and Computer Engineering at UAH. "On more than one occasion, parents used the words 'life changing' and 'once in a lifetime' about the camp."

That's because Tech Trek offered students the freedom to be creative - a freedom missing from most middle school curriculums. "The girls said that, at school, it was about getting the right answers. But at Tech Trek, it was about exploring possibilities and understanding that failure is part of the process," she says. "The process is so much more important than any answer, because the questions are going to change during the course of a forty-year career."

Biography

George Nelson received his Bachelor of Science, Master of Science, and Ph.D. degrees in Mechanical Engineering from the Georgia Institute of Technology in 2003, 2006, and 2009.  While pursuing his Ph.D., his research involved modeling and analysis of fuel cells and electrolyzers, with an emphasis on mass transport in porous fuel cell electrodes.  After completing his Ph.D., he served as an Assistant Research Professor at the University of Connecticut from 2009-2012.  His projects at the University of Connecticut focused on the investigation of mass and charge transport in electrochemical energy storage and conversion devices, primarily fuel cells and batteries.  During this time he also contributed to the development of three-dimensional imaging methods for energy materials based on x-ray nanotomography.  Dr. Nelson started as an Assistant Professor at UAHuntsville in August 2012.  His general research interests include transport phenomena, energy storage and conversion devices, sustainable energy systems, and multi-scale modeling and analysis.
