Hi, I'm Stu Dunn
Founder of SDL Behavioural Science Consultancy, FACS Certified, New Zealand's Micro Expressions, Body Language & Deception Detection Expert.

Becoming proficient with non verbal communication and teaching what I’ve learnt over the years has become an absolute passion of mine; starting with beginning the SDL Behavioural Science Facebook Page, then set up my first online course in 2011, and my first book on the subject True Lies, A Guide to Reading Faces, Interpreting Body Language & Detecting Deception in the Real World was published in 2013. 

During this time I’ve helped thousands of people around the world become proficient in reading body language, micro expressions and detecting deception – and I’d love to help you too.   

Here's a little about me:
I became the first Facial Action Coding System (FACS is the most detailed de-coding of the face, and universally recognized by psychologists and physiologists worldwide) Certified consultant in New Zealand, and continuing to study psychology, body language, micro expressions and FACS has helped me to become New Zealand's leading expert in this area. I was also one of the first in the world to achieve Master Level on Humintell's Mix Elite Micro Expressions software. 

I've worked with participants from New Zealand, Australia, United States, United Kingdom, India, Canada, Germany, Afghanistan, Portugal, Switzerland, Poland, Macedonia and Sri Lanka so far. This includes working with participants from the NZ Defence, IRD Fraud Investigators, Sri Lankan Customs, Homeland Security, Telecom NZ and Vodafone to name a few.

My main areas of expertise include: micro expressions, emotions and emotional surveillance, body language, deception, interviewing, training, business consulting, video analysis (evaluating truthfulness & credibility), FACS coding (videos, pictures and animation), sales training, assistance with criminal and private investigations.

This courses will change the way you look at interacting with people. Stu's course explains in detail how to develop the skills of analysing and interpreting non-verbal language. As an IT Analyst this skillset has created a major improvement in the outcomes I can achieve from interactions with colleagues and customers. 

I now have the skillset which helps identify when someone I'm dealing with is having an issue they're not willing to discuss, or is being less than truthful with me. The online course combined with Stu's constant Facebook "what's this expression mean" challenges are allowing me to develop and strengthen this skillset at a pace that suits me.

I'm half way through the course and loving it. My learning increases daily; this information opens up a new realm of understanding, whether for personal or professional needs. Stu Dunn has created the program to provide challenging exercises which are very achievable. 

He is always available for prompt and clear feedback, and the Facebook groups he's created allow for course-specific interactivity. I think this is invaluable, affordable training for anyone, no matter what reason you wish to develop this skill.

Dr. Svetlana Mamkina (Berlin, Germany)

The program is very very good, well structured. Being a Doctor in Math for me means it is always better when there is not too many extra words in study materials. And what is provided is just perfect.

I would actually like to take the time to thank you. I was very pleasantly surprised how well the course was organized. The modules were very well planned, easy to understand and to memorize. But what impressed me the most is amount of time and effort you put in to respond all my questions and giving all feedback, always in a detailed way. The knowledge received will be extremely useful not only in my work, but also in life. Thank you again.

Ceilidh Ap-Farendar (United Kingdom)

I did an enormous amount of trawling through all that Internet had to offer regarding online courses within this subject matter, as it has long been a fascination of mine, & so to find the best possible for me was very important, before choosing to go with Stu, & I can very happily say that it was absolutely the best decision & that I have loved every second!

Stu's teachings are packed full of quality information that's easily accessible & that steer you through the process of learning how to look & listen, & to understand & apply what you're perceiving. If this is already easy for you, then you will hone your skills & add to them exponentially, & if it's not then you will have everything you need, & with all the feedback & support you require! It is a lot of work, but I managed to complete each module in approximately a fortnight, around a busy life & very limited Internet access, & you are actually allotted plenty more time than that if needed. Each assignment was marked & the new module sent remarkably quickly, within a few days at most, with relevant feedback each time so I never felt out of the flow.

Couple that with the remarkably inexpensive Course fee & you really can't go wrong.
