This is quite a bad picture, but bear with me, my 4-year old digital camera has decided now is a good time to die.
This is Chad. Chad works for BGI. He used to work in the US and while I was in BGI, I made it my business to send him irritating e-mails about S&P 500 data. He has now come to the UK. This reinforces my personal belief that the whole world revolves around me and people travel from countries far away just to be close to the great Joel. I would note that Chad has not confirmed or denied this to date.
He is not related in any way to St. Chad, despite the apparent halo which is simply an unfortunate visual anomaly, nor the Republic of Chad. I would also like to quash the theory that he stars in One Tree Hill, a show I have never watched; you must be thinking of a different Chad.
