University of Cape Town in 2004 and later her BSc(Hons) degree in 2005 also from the University of Cape Town. She came top of her class for honours, winning herself the James Mohr Medal. In 2006 she moved to Johannesburg where she studied her PhD at the University of the Witwatersrand under the supervision of Prof. Jo Michael. During the following 4 years Susan worked as a Teaching Assistant and lectured chemistry to undergraduates. At the end of 2009 Susan completed her PhD entitled “Vinylogous Sulfonamides in the Total Synthesis of Indolizidine Alkaloids from Amphibians and Ants”.

In 2010 Susan started working as a research scientist at Ithemba Pharmaceuticals Ptd Ltd, a start-up biotech focused on drug discovery for neglected diseases. In 2011 she was promoted to Principal Scientist and with her increased involvement in managerial activities she decided to pursue a part-time MBA through the Management College of South Africa, which she obtained in 2014. Susan joined H3D as a Research Officer in August 2013 and in 2015 she retired from the lab bench to increase her involvement in project management and operations at H3D.

He completed his PhD at the University of Pretoria under the supervision of Prof Namrita Lall, investigating the antimycobacterial and quorum quenching potential of quinoline derivatives. Carel has ample experience in the field of phytochemistry, biochemistry, microbiology, enzymology and computational biology, with a special interest in mycobacterial biofilm inhibition. During his studies, Carel was invited as a visiting scientist to the University of Albany, New York, and the University of East Anglia, UK, where he investigated the inhibition of Mycobacterial biofilms and gained insights into the kinetics of mycothione reductase inhibitors, respectively. During his postdoc, Carel worked on discovering quorum quenching inhibitors and developing new assays for screening purposes. Carel has a passion for education and has mentored and supervised several postgraduate students at honours and Masters level. Carel joined H3D as an AMR investigator to establish and elaborate on the capabilities of the platform and enhance the overall impact of drug discovery efforts in the field of antimicrobial resistance

 In 2011, he was awarded a prestigious industrial postdoc placement at GlaxoSmithKline, Stevenage, UK, where he worked on medicinal chemistry projects in respiratory therapeutics with Dr Simon MacDonald. Richard returned to UCT in 2012, and continued to work for a further two years as a post doctorate fellow in tuberculosis drug discovery as a part of the SATRII (South African Tuberculosis Research Innovative Initiative) team under Chibale. Since taking up the position at the H3D, UCT, in 2014, Richard has been responsible for overseeing TB and malaria drug discovery projects that involve multidisciplinary teams (chemistry/biology/ADME/PK) at H3D/UCT, with external partners and collaborators (including IDRI, Lilly, GSK, DDU, NIAID) within the Tuberculosis Drug Accelerator (TBDA – a Bill & Melinda Gates Foundation initiative) and Celgene Global Health (acquired by Bristol-Myers Squibb in 2019).  Furthermore, he has played a major role in implementing research project management (Jan 2017 to present) across H3D, after a 10-week management training sabbatical at the end of 2016 at Novartis Institute for Biomedical Research (NIBR) in Cambridge, MA, USA.

Liezl Gibhard

Dr Liezl Gibhard

Senior Investigator | PK and NSG mouse model for malaria

Dr Liezl Gibhard is a research professional with experience in biochemistry across platforms in research, development and scientific analysis.
Read more.

She received her BSc (Hons.) and MSc degrees from the North-West University. She then continued with her PhD in Pharmaceutics at the same institution, carried out in the fields of malaria and nanomedicines. After completion of her studies, Liezl took up a post-doctoral position in the Division of Clinical Pharmacology at the University of Cape Town. Liezl received an NRF Innovation Fellowship to evaluate the pharmacokinetic and pharmacodynamic properties of novel antimalarial compounds administered alone and in dual combinations with artemisinins and derivatives thereof in in rodent models. Liezl joined the DMPK team at H3D on a permanent basis in mid-2015.

As H3D expanded her role expanded to establish and validate the NSG mouse model for malaria.  This model is used to correlate pharmacokinetics with pharmacodynamic readouts and optimization of dosing regimens for novel antimalarial compounds.
