Congratulations to all the FABIans that were capped at the University of Pretoria’s Autumn Graduation. A bumper cohort of eight PhD, 17 MSc and 35 Honours students from FABI were capped – a wonderful achievement and testament to the research excellence in the Institute. FABI is also especially proud of Dr Khotso Mokhele, one of South Africa’s most distinguished science leaders, who received an Honorary Doctorate: Doctor of Science (honoris causa) on 8 May in recognition of his extraordinary intellectual and leadership contributions to science, higher education and innovation in South Africa and globally. He has, for the past 15 years, served as an advisor to the leadership of FABI, supporting the development of its Avocado Research Programme. This led to the creation of a Research Chair at UP, funded by the Hans Merensky Legacy Foundation, which Dr Mokhele chairs.
