| Key Skills: |
Vibration, acoustic, and structural design, measurement, study, and consultation. |
| Technical Experience: |
Wide range of design Expertise including finite element modeling and analysis (time history, frequency response function, modal analysis) of structures, dynamic soil-structure interaction analyses, design and specification of vibration isolation systems, and noise specification and design. As the principal structural dynamics, he has been responsible for developing new concepts affording robust design and major cost savings. Has has published many peer-reviewed articles such as:
- “Vibration Impact of a 150-MW Cogeneration Plant on a Semiconductor Fab”, (with B. Davis), presented at ASA/INCE Baltimore, April 2010.
- “Conversion of Old Fabs/Labs – The Vibration Design Perspective”, (with B. Davis), presented at IEST ESTECH 2004 Conference, April 2004.

| Selected Project Experience: |
- Pacific Northwest National Laboratory, Richland, WA
Vibration design of 200,000 sq-ft 5-building nuclear materials research complex. 3-D FEM structural models allowed sensitive SEM/TEM imaging to operate in close proximity to mechanical equipment.
- US Army MRICD Replacement Facility, Aberdeen Proving Ground, Vibration design of new chemical/biological defense laboratory and animal holding facility. SEM/TEM and NMR labs required attention to fill material and slab isolation. Upper floors required dynamic design to accommodate mechanical systems and adjacent labs.
- University of Washington / Sound Transit LRT Impact, Seattle, WA Represent university in assessing vibration impact of $1.6B regional light rail project crossing campus. Conduct large-scale vibration surveys and assess impact on high-precision, vibration-sensitive laboratories.
- Inotera Fab 1, Taoyuan, Taiwan
Vibration design for new 100,000 sq-ft semiconductor manufacturing cleanroom facility. Created global 3D FEM models for structural design. Mitigate vibration from adjacent 300MW cogeneration plant.
- LANL CINT Gateway Facility, Los Alamos, NM
Vibration design for new 35,000 sq-ft nanoscale research gateway facility. Accommodate vibration-sensitive labs on first and second floors, and multiple structural concepts for the upper floors. Assess traffic-induced vibration impact.
- UCSF Community Center, San Francisco, CA
Structural dynamic evaluation and design of a gym floor directly above an Auditorium. Seattle Ferry Terminal Structural dynamic testing and evaluation of a terminal due to hydraulic lift system vibration and passenger traffic.
- SFPUC SEP Biosolids Digester Facility Project (BDFP), San Francisco, CA
Acoustic and Vibration Design of the multi-billion dollar existing facility modernization. We performed indoor acoustics, outdoor 3-D noise modeling of the entire facility and developed appropriate noise and vibration specifications.
- San Francisco SFO Terminal 3 West, San Francisco, CA
Acoustic and Vibration Design of the existing 3W terminal upgrade and expansion. We performed indoor acoustics modeling of the departure spaces, addressed Baggage Handling Systems noise and vibration, outdoor-indoor noise mitigation and design of the façade and the terminal envelope, mechanical noise and vibration design and mitigations. I was the principal in charge and project manager for this project.
