About the Instructor

University Lecturer & Youtube Statistics Teacher

Hi everyone! My name is David, and I'm a Udemy instructor for Statistics and Econometrics. I hold a PhD in Finance from the University of New South Wales, Australia, and am currently a Lecturer in Aviation Finance. I absolutely love teaching! I like to break down complex concepts into little bite-sized pieces using simple and often silly stories for my students. The look on their faces from clueless to "ah ha!" is priceless, and means a lot to me.

In particular, I love teaching Statistics and I currently have a Youtube channel ("Dave Your Tutor") devoted to teaching statistics to newbies and those struggling with the subject. My channel has over 320,000 views and 1,600 subscribers, and is growing rapidly! I also run a Facebook page "freestatshelp" where I assist students with statistics from around the world for free. Come and check it out!

Yup, I'm a nerd.

Apart from teaching, I'm also an active researcher at the university and research in all sorts of stuff. I'm particularly passionate about my following research projects:

* Using microeconomics to improve the way funds are raised for charitable causes,

* Using agent-based modelling to observe how information goes viral on social media, and

* How exposure to technology and the Internet affects children's ability to concentrate.

Once a year, I go to a village in Phang Nga, Thailand, to volunteer and teach English at a disadvantaged (poorly funded) primary school for Burmese students. I would have to say one of the best times of my life is when I was staying in a small village in Thailand (Thai Mueang), teaching English to the Burmese kids, riding my scooter, working out of ym lap top, and just living a simple life.

Beauty lies in simplicity.
