@sqwishy What is the chance that Prof. Loh's wife is named Debbie and the one on this forum made by Prof. Loh is also known as Debbie?
I could be wrong, but I doubt that raising three children will really take that much time (Unless Debbie has other things to do).
Also, even though she might not have a formal math background, she did teach herself math. I believe that Debbie could learn this because it is only for middle school competitions. Also, the website states that Debbie taught her kids math so she must have had some teaching experience.
Debbie's location is Pittsburg and even though I could not find where Prof. Loh lives, I did find that Carnegie Mellon University(The place that Prof. Loh teaches) is also located in Pittsburg.
I could be wrong because I'm not a stalker and I don't plan to trace her IP address and fly to her.
