About Khir Johari
Born and raised in Kampung Gelam, Khir Johari rediscovered his roots while living in Silicon Valley. A mathematics educator by training and a foodie by birth, Khir gets a kick from getting kids excited about learning mathematics and wouldn’t mind cheese tasting in class to teach the concept of percentage and angles in a circle. The combination of history addiction and the love for Nature’s beauty has made him an incorrigible traveler.
