# About me: Hui

Hi. My name is** Ian Huitson** but everyone, except my Mum, calls me** Hui**…

I work as a Consulting Mining Engineer in Perth, Australia. I have a Bachelor of Engineering Degree (Mining) from the Ballarat College of Advanced Education in Australia.

I am passionate about scheduling and budgeting, simulation and mathematics but more importantly is their application to real world problems.

I have been using spreadsheets since Visicalc and have used Lotus 123, Open Access, Quatro Pro, 20/20 and Excel.

I was first awarded a Microsoft MVP (Excel) Award in October 2013 for my contributions to the Excel community. It was re-awarded in October 2014.

I should add that these contributions are mostly here at Chandoo.org and at Excel Hero, see below.

Why do I start equations with a =+ ? Because Open Access used to start equations with a + and it has just stuck, although I am getting better at not doing this.

Open Access also had a great function ! which I often wish Excel had. In use you could do something like convert Celsius to Fahrenheit Enter =(9/5)*!+32 into a cell. Then enter say 20 into the same cell and the cell would display 70. The ! took the input directly into the cell and used it in the formula and displayed the answer in the same cell. The cell still has the equation.

I am married to Eva, and have 5 children. You can see a few wedding snaps here.

In 2009 I took 9 months off work and we did a bit of traveling and during this time I started answering questions on Chandoo’s, newly setup, forums where I have helped out ever since.

In May 2010, Chandoo asked me would I write an article on Monte Carlo Simulation after I had described the process in a post. This resulted in the well received Data Tables & Monte Carlo Simulations in Excel a Comprehensive Guide. I have written a further 70+ posts since then as well as Starting and Authoring the Formula Forensics Series.

I hope you enjoy my contributions below:

In the early 2000’s I used to be a Beta Tester for John Walkenbachs PUP utilities.

During this period John and I would correspond regularly.

When I developed the Excel Mandelbrot without VBA I sent John a copy

Unbeknown to me John acknowledged the effort with this: Excel 2007 Bible
