Biography

Dr. Zang joined PNNL in January 2017. She is a postdoc/applied physicist in the Bioacoustics & Flow Laboratory, Energy & Environment Directorate. She got her Ph.D. degree in Applied Marine Physics from University of Miami in 2016. Her Ph.D. research focused on the acoustic Green’s function extraction in the ocean through ambient noise interferometry and long-range deep-ocean acoustic communication, with applications to acoustical oceanography and geoacoustic inversion. She is an expert in understanding sound propagation in the ocean through theory, acoustic modeling, ocean experiments and signal processing. She has participated in four research cruises and accumulated 15 days of research cruise life, with abundant experience in designing and performing ocean acoustic experiments. She got her Bachelor's degree in Marine Technology from Ocean University of China in 2011, with a mixed background in ocean acoustics and electrical engineering.

At PNNL, Dr. Zang's research extends to bioacoustics, including assessing the effect of sound and vibration from anthropogenic sources on the migration of salmon, evaluating the effect of swimbladders on the beam pattern of acoustic tags, and monitoring migrating American eels with ARIS imaging sonar. In addition, she collaborates with PNNL's battery experts to monitor the status of vanadium redox flow batteries by designing an ultrasonic nondestructive measurement device. Her expertise has extended to acoustic device design and nondestructive test, data analysis with machine learning methods, and sonar image processing. She is also interested in evaluating and mitigating the effect of marine hydrokinetic energy facilities on marine animals.
