Senior Data ScientistMatthew Dennis
Chief Executive Officer +
Senior Data ScientistMatthew has an unusually diverse background, having worked as a school teacher and a composer of classical music prior to his current role as a data scientist. Working as a teacher refined his ability to clearly convey complex ideas, and he brings an emphasis on quality and precision to his work with data. Matthew particularly enjoys using R, and gets excited about projects that involve web scraping or building applications with shiny.
Outside of work, you’ll probably find Matthew running – either on the slopes of Table Mountain, after a frisbee, or after his one-year-old daughter.
Matthew is creative, thorough + adventurous

Gavin Masterson
Senior Data Scientist
Gavin Masterson
Senior Data Scientist
As an animal enthusiast studying Zoology & Ecology was a natural choice for Gavin. He is always interested in real-world applications of knowledge so his PhD made use of occupancy modelling to map reptile species' distributions within a managed, grassland reserve. The research aimed to understand and alleviate some of the difficulty associated with studying hard-to-find reptiles.
When Gavin isn’t working you can generally find him in one of three places:
- on the hunt for adventure, looking for (and sometimes finding) snakes, interesting species of lizards, scorpions, spiders, and more,
- Swimming (particularly in open water),
- Hitting a tennis ball.
Gavin is friendly, confident + curious

James Theil
Senior Data Scientist
James Theil
Senior Data Scientist
Another member of the team to have a diverse background James has taught English in South Korea, been an addiction counsellor and worked as a post-graduate lecturer and tutor all while studying Psychology through the University of KwaZulu-Natal.
While working on his Masters James very quickly found himself pulled towards quantitative research. His Masters research, which focused on group behaviour, aimed to simulate an interacting exchange network using an agent-based model while his current PhD research makes use of reinforcement learning integrated within agent based models. The aim of his PhD research is to tap into the mechanisms that generate and sustain inequality in society.
When James isn’t working on his PhD you can find him either camping, crafting something magical at his woodworking station, fishing or whipping up some sourdough!
James is empathetic, meticulous + determined

Clarissa Willers
Technical Writer
Clarissa Willers
Technical Writer
With a PhD in Environmental Sciences, specifically focusing on Soil Microbiology, Clarissa has a passion for the “world under the microscope”. Her ability to grow any type of cell culture, microorganism, or plant, provides her with a diverse set of skills to master complex systems. She is fascinated by the fact that minuscule units can cooperate, co-exist, and communicate to form a harmonized intricate system.
Data science follows this same trend, and she’s excited when a few lines of code on a computer screen can run a whole website or social media platform. Fascinating!
After hours, Clarissa loves to spend time with her loved ones on the farm, as well as working in her vegetable and rose gardens.
Clarissa is reliable, diligent + adaptable
