Acoustics, Mechanical Engineering, Noise Control, underwater acoustics, Vibration

Dr. Andrew Barnard is the director of the Great Lakes Research Center and an associate professor of Mechanical Engineering-Engineering Mechanics at Michigan Technological University, where he has been a faculty member since 2014. He previously was a research associate at the Applied Research Laboratory at Penn State University for eight years. He received his BS and MS in Mechanical Engineering from Michigan Tech in 2002 and 2004, respectively. He received a Ph.D. in Acoustics from Penn State University in 2010. Dr. Barnard is Board Certified by the Institute for Noise Control Engineering (INCE) and is a Certified LabVIEW Developer (CLD). Dr. Barnard has interests in acoustics, noise control, and vibration, as well as water resources and marine technology. Currently, he is interested in the commercialization of thermoacoustic thin-film loudspeakers made from carbon nanotubes (CNT). He is also interested in noise control methods for underwater electro-mechanical machines, such as electric motors and actuators. Though-ice acoustic propagation and on-ice source localization and tracking using machine learning are another current areas of study for Dr. Barnard. Finally, he is interested in the implementation of the maritime autonomous vehicles in commercial and defense applications.

Acoustics, Aircraft Safety, Levitation, Mechanical Engineering, soundwaves, Ultrasonics, Ultrasound

Professor Bruce Drinkwater is based in the Department of Mechanical Engineering. His research involves the use of ultrasound to test for engineering defects and cracks in safety critical structures such as power stations, oil and gas plants, sewage pipes, and aircraft engines. This method of non-destructive testing is used to intercept and prevent serious damage. He was awarded the Roy Sharpe Prize for his work in ultrasonic imaging that led to the invention of a special probe used to ensure that aircraft are safe to fly. Professor Drinkwater is also developing the use of sound waves to move and manipulate very small materials, a process called acoustic levitation that has potential applications in small-scale manufacturing, 3D printing and the assembly of living tissue. He co-invented the world鈥檚 first stable ultrasonic tractor beam - which attracted major media interest - and was awarded a Royal Society Wolfson Research Merit Award for this work. He is also Director of the EPSRC CDT in Future Innovation in Non-Destructive Testing (FIND).

Acoustics, Speech Intelligibility, Voice analysis

Pasquale Bottalico earned his bachelor鈥檚 degree in Telecommunications Engineering from Univerist脿 Mediterranea di Reggio Calabria (Italy), while simultaneously pursuing a degree in Opera Singing at the F. Cilea Music Academy of Reggio Calabria (Italy). In 2005, he moved to Turin where he earned his master鈥檚 degree in Telecommunications Engineering from Politecnico di Torino (Italy). For his master鈥檚 thesis, Dr. Bottalico combined his studies of engineering and music to explore musician perceptions of acoustics and the correlation with objective index from ISO 3382.
 
Dr. Bottalico earned his PhD in Metrology, studying acoustics with particular attention to the uncertainty of measurements and statistical analysis of data. For his dissertation, he investigated classroom acoustics of primary schools and its relationship with safety, examining the students and the teachers separately. Specifically, he: 1) described the speech intelligibility in the classroom, which affects students鈥 learning; and 2) examined how the acoustical features of a classroom can influence vocal performances. Dr. Bottalico is particularly interested in the professional voice user and singer techniques, as well as the definition and the quantification of vocal load. Other fields he is interested in are Speech Intelligibility, Room Acoustics and Musical Acoustics. Bottalico is also a professional chorister, performing under such prestigious directors as Rafael Fr眉hbeck De Burgos, Yuri Ahronovitch, Jeffrey Tate, Juanio Mena, Gianandrea Noseda, Ottavio Dantone, Wayne Marshall, Helmuth Rilling, Christopher Hogwood, Robert King and Ivor Bolton.
