David is currently employed as a senior lecturer in the department of statistics and actuarial science at Stellenbosch University, a post which he has held since January 2017. David sits on a number of committees, both internal and external to the university, including for the National Graduate Academy for Data Science. Prior to joining Stellenbosch University, David held a one year post doctoral fellowship within the STOR-i center for doctoral training, at Lancaster University.

David continues to work on the problem of finding optimal projections for clustering, and has also extended his scope into (primarily) the areas of model selection, non-parametric smoothing, and the clustering problem in general. However, he has peripheral interest in a large collection of areas relevant to data science, machine learning and methodological statistics.
