About Prof Dirk Opperman
Prof Dirk Opperman obtained his PhD in Biochemistry at the University of the Free State in 2008. This was followed by postdoctoral research on directed evolution with Prof Manfred T Reetz at the Max Planck Institute for Coal Research (Germany). In 2010, he was appointed in the Department of Microbiology and Biochemistry. He subsequently established structural biology at the UFS, and his current research focus lies at the interface of evolutionary and structure-function relationships of biocatalysts, and their application in green chemistry. He is an NRF B-rated researcher with co-authored papers in Science, Nature Communications, and Angewandte Chemie.
His research has been funded by both local and international organisations, ranging from industries such as SASOL to the Global Challenges Research Fund (GCRF, UK). He has a long-standing collaboration with researchers at the Delft University of Technology (TUDelft, the Netherlands) and is currently part of a European Research Area Network Cofund (ERA-NET Cofund) partnership on Food Systems and Climate (FOSC) that develops biocatalysts for upcycling waste.

The University of the Free State (UFS) hosted NASA Deep Space engineer Christopher Jacobs on 27 March 2017 at the Bloemfontein Campus. The engagement was hosted by Prof Matie Hoffman of the Department of Physics and the Department of Institutional Advancement, in collaboration with the US Consulate General in Johannesburg.
Jacobs is stationed at NASA’s Jet Propulsion Laboratory (JPL) at the California Institute of Technology and has served as the Reference Frame Calibration task manager for 25 years. In this role he has been responsible for delivering the reference frames used to navigate NASA missions such as the Mars Science Laboratory to planetary targets.
His visit to the UFS included a presentation to the Department of Astrophysics at the Faculty of Natural and Agricultural Sciences and at the Naval Hill Planetarium in Bloemfontein where he spoke on Stellar GPS: Navigating the Solar System. He also spoke about the latest research and developments at NASA in Astrometry. The visit will establish and develop shared interests and possible collaboration with UFS and other institutions of interest in the country. “South Africa, because of its well-placed geographic location in the southern hemisphere, holds a lot of answers to astronomy,” Jacobs said.
He has an active interest in professional and public education, and outreach, having given public lectures around the world. “Astronomy brings people together and is a point of common interest that is key in solving environmental and geographical challenges such as climate change, therefore global cooperation is important,” he said.
Prof Hoffman welcomed the initiative by the US Consulate and the possible outcomes of joint efforts to position the UFS as a key partner in South Africa on NASA’s astronomy projects. In the coming weeks Jacobs will speak at high schools in Gauteng including the Mae Jemison US Science Reading Room in Mamelodi, Pretoria, a centre that is focused on promoting science education.
