Professional History:

Dr. Trousil completed her B.A. degree in physics and mathematics at the University of Wisconsin Eau Claire in 1993. She earned her M.A. (1995) and her Ph.D. (2002) in physics from Washington University in Saint Louis.

As a graduate student in the Laboratory for Ultrasonics under the direction of James Miller, Dr. Trousil studied the interaction of ultrasound with anisotropic, inhomogeneous biological and man-made materials. The title of her Ph. D. dissertation was Ultrasonic Propagation in Inhomogeneous Media: Toward Quantitative Ultrasonic Imaging. Graduate students in the Laboratory for Ultrasonics are encouraged to become active participants in the strong medical and industrial collaborations that the research group has fostered for many decades. Early in her graduate career Dr. Trousil participated in the ultrasonic characterization of a novel, site-targeted ultrasonic contrast agent, developed by Cardiology collaborators at the Washington University School of Medicine. In 1999, she spent six months at ATL Ultrasound in Seattle, Washington continuing her research on the ultrasonic characterization of cardiac tissue and facilitating a new collaboration with this ultrasonic imaging system manufacturer.

In 2001, Dr. Trousil joined the staff of the Washington University Physics department as a Lab Coordinator for the introductory physics program. In that capacity, she trained and mentored graduate teaching assistants, developed laboratory curricula, administrated the introductory physics program, and served as a liaison between course instructors, teaching assistants, and students. In 2003, she joined the Physics faculty as a Lecturer. She teaches calculus-based introductory physics (Phys 117/118) and a course for graduate students on physics instruction (Phys 597/598).

Dr. Trousil is a member of the American Association of Physics Teachers, the Acoustical Society of America, and the IEEE Ultrasonics, Ferroelectrics, and Frequency Control Society.

Education Outreach:

Summer Science Content Institutes: Develop and lead science content workshops for K-8 in-service teachers in the Riverview Gardens School District.

Hands-On Science K-8 Education 6000 Courses: Instructor for Washington University graduate course (ED6011: Sound and Light) for in-service K-8 teachers. The course is part of a series of inquiry-based science courses for teachers that blend science content with classroom appropriate activities.
