Members of the SDASL Lab attended the 37th International Modal Analysis Conference at the end of January 2019. At the conference, ninr students presented papers along with other papers and presentations by faculty.
The SDASL always makes a significant set of presentations at this international conference each year. Many of the papers spanned a wide range of topics currently under development in the SDASL for funded and unfunded projects including Eglin Air Force on Nonlinear Response Analysis, NSF Sustainable Energy Pathway for Wind Turbine Blade Manufacturing, NSF CMMI funded Novel Acoustics-based Structural Health Monitoring of Wind Turbine Blades, Naval Underwater Warfare Center Bragg Scattering research, Honeywell and Sandia Fixture Neutralization efforts, Redstone Arsenal work on Optical Dynamic Measurements and other projects. Many of the conference's attendees noted the high caliber of research and especially the quality student presentations at the conference.
During the conference, Zhu Mao also gave the very prestigious Sage Publishing Young Investigator Lecture entitled “Non-Contact Modal Testing and Uncertainty Quantification in Structural Dynamics Identification”. Also, note that Zhu Mao received the Young Investigator Award from the US Air Force Office of Scientific Research in 2018 as well as the SEM D. J. DeMichele Scholarship Award in 2011.
In attendance were: Deborah Fowler (PhD candidate ’21), Murat Inalpolat (Assistant Professor Mechanical Engineering), Tyler Doveno (MS candidate ’19), Tim Marinone (ATA Engineering - BS/MS ’12’), Lou Thibault (MIT-LL BSMS ’12), Yuanchang Chen (PhD candidate ‘19’), Julie Harvie (Sandia Labs - BSMS ’13’), Jesus Reyes (Visiting Professor UML PhD ‘16’), Dagny Joffre (PhD candidate ’19’), Aral Saffari (PhD candidate ‘19’), Peter Avitabile (Professor Mechanical Engineering UML PhD ‘98), Javad Baqersad and wife (Kettering University UML PhD ’15’), Dan Rohe (Sandia PhD candidate ’21), Chris Beale (PhD candidate ’19’), Brandon Zwink and wife (PhD candidate ’20), Chris Niezrecki (Professor Mechanical Engineering), Zhu Mao (Assistant Professor Mechanical Engineering), Patrick Logan (PhD candidate ‘19’), Tina Dardeno (PhD candidate ‘19’) and Ryan Schultz (PhD candidate ‘19’).
