Meet Our Postgraduates

The Department of Process Engineering boasts a thriving postgraduate research environment with approximately 130 registered postgraduate candidates, including researchers from across Africa and the globe. Our department is also proud of an active Postgraduate Student Council (PGSC), which leads and serves the postgraduate cohort with academic and social support, as well as community engagement. Meet them below!

Meet our Postgraduate Student Council


I am a fun-loving person, but I enjoy music more than a lot of things in life. My hobbies reflect that: guitar playing and songwriting.

Before living in Stellenbosch, I grew up and went to school in Gaborone, Botswana. Attending an international school exposed me to many people from different places and backgrounds, which I feel has made me very welcoming and friendly.

Welcoming and International Students

I have a love-hate relationship with coffee. I like to laugh and like to think I have a sharp sense of humour, but my jokes are mostly lame. I also have a lowkey obsession with anything Korean. Shame.

Veronica Lourens

Secretary & Socials

I am an outgoing person always willing to be of help and create a welcoming atmosphere around me. I like to smile and find the bright side to every situation I find myself in. Call me an optimist!

I have been at the faculty since 2016 now and it has become a special place to me. I hope through my effort and dedication as an engineer I can make 2022 an extra fun year to be a postgraduate. Also, I like woodworking, camping, and most socials interactions in general.

Socials & PG Symposium

I am from East London, in the Eastern Cape. I enjoy console and tabletop games and a bit of music. I play the guitar, bagpipes and trumpet, although I haven’t actually touched a
trumpet in years…

Izak Schlebusch


I grew up on a dairy farm near George. I completed my BEng in Chemical Engineering at SU. During my final year project, I developed a deep interest in bioprocessing, especially anaerobic digestion. As a hobby, I enjoy playing the clarinet. I see myself as a person with a high standard of work ethics, who values honesty and pays attention to detail.

Professional Summary

I am a passionate and innovative chemical engineer with a love of learning and building things. During my school years and undergraduate degree I strived for academic excellence and I am currently applying that same philosophy towards completing my master’s degree. I also have a full year’s working experience at a water treatment company called Proxa, where I did everything from R&D to site work to assisting with consulting work.

My master’s degree focuses on environmental engineering by finding the most environmentally friendly way of recycling lithium-ion batteries. In industry, I wish to continue down a similar path by directing the local market towards green and sustainable engineering. I want to work on the front line by building plants, running experiments and advocating for a better future through the process of diligent study and scientific advancement.
