As an educator, Dr. Tu’s highest priority is to teach strong fundamentals and to relate them to real-world problems. At the graduate level, Dr. Tu teaches Principles of Structural Vibration (MAE 513). This course is an introductory course on mechanical vibration that follows a traditional exposition. He places a strong emphasis on the formulation of vibration problems and an additional emphasis on its broad applicability beyond mechanical systems, such as music and science. Dr. Tu will introduce a new course in Precision Laser Material Processing in the coming semesters for both graduate students and seniors.
At the undergraduate level, Dr. Tu teaches Manufacturing Processes (MAE 496M) and Analysis for Mechanical Engineering Design (MAE 415). In MAE 496M, the goal is to review the major manufacturing processes, how design is carried out using these processes, and how these manufacturing processes solve engineering problems. Dr. Tu shows through proper dimensioning how different processes are integrated to achieve required tolerances. In MAE 415, Dr. Tu teaches design from the perspective of how required precision is achievable; bringing manufacturing into the design process from the beginning.
The role of lasers in engineering is fascinating; lasers are unique in that they operate on the basis of a purely human-made physical phenomenon and their use brings in understanding of electrodynamics, mechanics, and thermodynamics, making the subject rich and complex — the number and variety of applications are almost limitless. Dr. Tu expects his graduate students to have a strong sense of urgency and be an active thinker to attack problems, moving forward aggressively. This philosophy will help students to develop into confident solvers of engineering problems, making them well-prepared for the workplace.
Outside of work, Dr. Tu enjoys spending time with his family and playing tennis. As hobbies, he enjoys photography, collecting classical cameras from the perspective of precision machine design, and rebuilding musical instruments based on engineering vibration analysis.

Dr. Tu is interested in laser material processing, high speed machining/spindle technology, precision engineering, mechatronics, modeling, monitoring, and control of dynamic systems. Dr. Tu's long term goal is to contribute to the advancement of lasers in engineering. Currently, Dr. Tu is 1) studying the fundamental mechanisms in laser welding of aluminum to improve the repair of fatigue cracks in aerospace materials, 2) using lasers as a manufacturing tool and design approach to improve the energy efficiency of solar panels, and 3) studying laser micro-hole drilling for fuel injectors, nozzles, and medical devices. Laser micro-hole drilling offers significant advantages resulting from its ability to produce high depth-to-cross-section ratios and fast material removal rates.
