Performance Analysis


3D Motion Analysis

I have been using VICON Nexus for 3D motion analysis alot of over the years, especially currently for my PhD. Recently I have learned and helped to conduct studies using other systems such as the XSens and the SIMI.


Automation, Signal processing (e.g. 3D motion analysis, EMG etc), data wrangling and analysis and Creating Awesome Balls of Fire


I mainly use R for Data Analysis and Visualisation. An example can be seen in the Projects - Data Analysis

SQL and Athlete Management System (Database)

Over the years as a coach, I have accumulated thousands of spreadsheets, data etc. A few years ago, I started trying to organise them, especially when as Sports Science Coordinator, I had to consolidate data from different disciplines (e.g. YPIs, training programs, medical, physiological, nurtitrional plan, videos). This triggered my passion for database management. And as more coaches will tell you, the more information we have about the athelete, the better we can train them.

Notational Analysis

As a rugby coach, I am always interested in notational analysis, which is the study of strategy and tactics in team sports. I have recently published two such papers, one on hockey and one on water polo.

Strength and Conditioning

Strength and Conditioning Coach for the past 14 years. And have worked with a wide variety of athletes across the whole development spectrum


Other than Strength and Conditioning, I also coach Rugby, Athletics and Weightlifting


Emergency Medical Technician (Basic). I started out my sports science career as a Sports Masseur/Sports Trainer (i.e., first aider/rehabilitation assistant) and spent several years providing first aid, other medical support and rehabilitation to fellow athletes. Earning my Emergency Medical Technician (Basic) was a natural progression to achieve a higher level of skill and competency. And while I have moved into the area of Biomechanics, I make it a point to always maintain my currency and competency in these skills as I sincerly do enjoy doing it.


Experienced in venipuncture for the purpose of drawing blood.

AusREP (Level 3)

Australia Register of Exercise Professionals (AusREP). Level 3 (Advanced) represents an exercise professional who has a more progressed level of knowledge and skill and has considerable experience to draw upon. It is expected that a professional at this stage of development can combine the use of competencies, experience and critical thinking skills in practice.

Athletic Training Competency

The Athletic Training Competency (ATC), is the culmination, of more than 4 years of practical coaching experience and reinforced by numerous studies and observation that looked at the development of Singaporean youths at the Singapore Sports School. The results is a 4-5 years program long term physical development that is based on the youth’s biological maturity (pre-pubescent, pubescent and post-pubescent) and guided by their actual physical capabilities. The ATC is a guide on what to teach/coach and focus on for each individual athletes and can be used by any trained PE teacher or Strength and Conditioning Coach. It does not require any invasive determination of the youths’s biological maturation and instead depends on a fairly consistent tracking of the youths physical development (eg. height etc.). One of the best project that I had the honor of leading and working on.

Stretch Shorten Cycle Across the different Maturational Stages (Pre, Pubescent and Post).

At the Singapore Sports School, we embraced the Long-Term Athletic Development Philosophy. However at that time, LTAD, was still largely empharical especially for Asian youths. I embarked on a project to try to understand the development of stretch shorten cycle across the different maturational stages (Pre, Pubescent and Post).

Youth Specific Basic Movement Screening @ Singapore Sports School

Created a youth-specific basic movement screening to assess, the movement and physical competency of the new students (aged 11 to 12) to the Singapore Sports School. The physical screening ensured that we were able to spot any deficiencies in basic movement patterns due to early specialisation in sports and/or lack of exposure to other basic movements. This helped to ensure a more even and holistic physical development and time for the students at the school.

Projects (Data Analysis)

Some of my initial projects that I embarked on to develop my Data Analysis skills using publicly availiable data

Determinants of Red Wine Quality-.

Research Question: Which chemical properties influence the quality of red wines? Background: Red Wine quality is graded by experts on a scale of 0 (very bad) to 10 (very excellent). To help understand what are the factors that determine the wine quality, the physicochemical properties of the wine was investigated. This is a qualititave measurement. By examining the physicochemical properties of wines of different grades, it might be possible to investigate whether there are factors or variables that can help determine the quality of red wine. This can help to quantify some of the grading process of the what is eitherwise a very qualitative measurement. This information in turn can be used in the future to help create a preliminary grading of wine quality (based on quantifiable measures) or something smiliar alomg that line.

Testing a Perceptual Phenomenon - The Stroop Effect

In this project, I investigated a classic phenomenon from experimental psychology called the Stroop Effect.

The Story so Far…….

Summary * Ground Up - From Sports Massuer to Sports Scientist and PhD Candidate * Broad based and interdisciplinary * Deepening specialisation

1) Ground Up I am most proud of the fact that I started my journey in this industry from the ground up and through continuous upgrading and learning, rose through the ranks. I started as a Sports Masseur after compleing my Basic Sports Massage ourse. During my times as a Sports Masseur, I took additional course to upgrade myself such as the Sports Trainer cours, which allowed me to take additional roles and responsibilitities such as Sports Trainer to sports teams in Singapore. During my 3 years as a Sports Trainer, I completed my undergrdaute degree in Science (Sports Science).

Upon completion, I took on the role of Strength and Conditioning Coach at the Singapore Sports School for more than 6 years, in which I completed 2 post-graduate degrees as a full-time student while working full-time at the Singapore Sports School. I am especially proud of my Masters by Research, in which I was able to conduct a research project on the development of stretch shortening cycle in youths across different biological maturation. During this time, I also expanded my knowledge and skills in the area of notational and performance analysis. These provided me a complimentary skills and allowed me to see sports science and training from a more holistic point of view.
