Wits alumnus and biologist expert Sive honored for her contribution to science
Professor Hazel Sive was awarded an honorary doctorate in engineering by Wits University. Photo: SuppliedLearning about the development of frogs at Wits University in the late 1970s sparked an interest in the young student Hazel Sive that led to her now being considered a world-renowned expert in the study of facial deformities as well as fundamental mechanisms underlying face and brain formation.
A research project assigned by her Wits lecturer, Professor Barry Fairbairn, investigated the South African claw-toed frog I was tasked with collecting frog eggs, growing them to the next step called embryos, which grow to become tadpoles. I did this on the top floor of the Wits biology building, keeping thousands of embryos in rectangular plastic dishes.
Sive then led research groups that contributed unique and crucial knowledge and defined dozens of genes and novel processes by which cells work together to build the face and brain."Much of our work has used frogs as a model for people, the same kind of South African frogs I first met in the biology building. What I learnt about frogs at Wits has eventually made me a world expert in this system," Sive said.
Maybe 10 ridges, exactly the same height and exactly parallel. I had no idea what this meant, but I thought it was amazing that such perfect geometry could be built in an ant.
