A. TEACHING
(1)Average teaching feedback (lectures and tutorials) over last 3 years was
about 4.6. Average teaching feedback over the previous 22 years was about 4.3.
(2) Lectures presented at NTU
I have presented the following lectures at NTU:
1) Non-Destructive Testing (NDT),
i) Ultrasonics, X-ray, Eddy Current, Magnetic Particle, Liquid Penetrant
2) Aerospace Engineering
i) Aircraft Structures
ii) Aircraft Failures
iii)Fracture Mechanics
3) Materials Engineering
i) Metals, Composites, Microelectronics and other materials
ii) Advanced Materials Characterization Techniques, SEM, TEM, EDAX etc
iii)Corrosion
4) Mechanical Engineering
i) Engineering Measurements
5) Physics
I have worked for eleven years in the UK NDT industry engaged in R and D work
and writing and overseeing NDT procedures for manufacturing companies. I
experienced working in the heavy fabrication industry (2 years with
International Combustion Ltd) and the aerospace industry (9
years with Rolls Royce Ltd). I have worked in NDT collaboration projects with
RSAF (Republic of Singapore Air Force) for the past 17 years.
I consider this industrial background unique for a university lecturer and this
enables me to teach NDT at university level. This knowledge and experience is
difficult to derive from text books. My students reach near level 3 capability
in ultrasonics, xray, eddy current, magnetic particle and liquid penetrant
testing. Level 3 is the highest qualification level required to work
in the NDT industry. I have received good feedbacks from students.

(2) Achievements with local significance (Research activities)
I was a collaborator for an A-Star funded project (S$1,600,000) to develop the
world’s first automated aircraft wing inspection system. I supplied all the non-
2
destructive testing knowledge required for the system and designed the
ultrasonic testing head required. The system had been used for the automated
inspection of the RSAF’s (Republic of Singapore Air Force) F5 fighter
aircraft. The system remains the world’s first and only automated dripless
immersion ultrasonic system capable of following any surface contour by
automatically the specimen surface contour using a vision camera and laser range
finders carried with a single arm robot. The system is patented.
I have collaborated with RASF for 17 years on Non-destructive testing projects
which have resulted in them developing more effective and efficient nondestructive testing procedures in all the main NDT techniques. The most
significant was developing the lock-in thermographic testing technique for RSAF
aircraft. Theoretical models were developed to predict results enabling enhanced
setup and testing efficiency. As a result of this work RSAF purchased an
identical system since they were so confident in its testing capability and
their system is currently part of RSAF inspection procedures. Recently RSAF
provided me with a fund of $S30,000 to conduct a feasibility study to
evaluate and design a automated radiographic system for their use.
I am currently working as a collaborator for a Simtech funded project (S$1.2M)
on “Development of a 3D carbon nanotube xray system”
Recently a MOU was signed between A-Star, Boeing, EADS, Rolls Royce and Pratt
and Whitney to jointly fund Aircraft MRO projects in Sim-tech. A survey carried
out last year amongst all aircraft MRO companies in Singapore found that
Aircraft Non-Destructive Testing (NDT) should be a major research area. Of the
first four projects selected to receive significant funding from this agreement,
two are in NDT, Sonic Techniques and Thermography. These projects which have
just started each have a funding of $S1,200,000. I am a collaborator to both
projects.
I have also collaborated with numerous other local companies on NDT projects,
E.g. Singapore Airlines, ST Aerospace, SMRT and Matsuhita Refrigeration
Indusries. Nearly all final year projects which I propose are sponsored by
industry. About 15 part time MSc dissertation students have graduated under my
supervision conducting projects of relevance to their companies. NDT is a
valuable essential technology which need to be developed by all advancing
countries like
Singapore. It is required in many areas of technology e.g marine, construction,
oil and gas, electronics etc. The most important area is in aerospace, the
subject of NTU’s new degree course.
I am familiar with essentially all NDT procedures used by companies in Singapore
and I can develop and write NDT procedures for their testing problems.
I gained 11 years of Research and development and in manufacturing in NDT when I
worked in the UK and I have been able to impart this knowledge to many students
and companies in Singapore.
I consider I have benefited the local industry considerably with my knowledge of
this valuable subject in both collaborative research projects and teaching.
(3) Achievements earning significant publicities for the University (External
research funding)
In 2001, General Electric (GE), USA, fully funded a NTU project under my
supervision to develop software to generate radiographic techniques. This was as
3
result of them reading one of my papers, “A computer program to generate
radiographic and magnetic particle inspection techniques", British Journal of
Non-Destructive Testing, UK, Vol. 32, No. 6, pp. 303-307, 1990 “. The paper
highlighted for the first time, the theoretical logical procedure needed to
determine specimen and defect through thickness values using radiographic film
density or real time sensor grey level measurements. The funding provided was
S$140,000. The project resulted in software which GE are utilising internally.
(4) Service as editor for international journals

(6) Service as a reviewer

local chapter) on Experimental Mechanics (230 papers accepted).
(7) Session chairman / (special) session organizer in conferences
