Additional work regarding ancient starch research came in a 2018 paper which addressed issues within this field of research with reference to taphonomical as well as taxonomical issues, helping to create new guidelines and criteria for future ancient starch analysis. In 2021 he published a paper titled "Earliest Olduvai hominins exploited unstable environments ~ 2 million years ago. This paper discovered the earliest archaeology at Olduvai Gorge and showed that the earliest hominins here were occupying diverse unstable environments. This ability to occupy unstable environments allowed hominins to move out of Africa into diverse habitats.

Similar research regarding human evolution, subsistence and technology saw him investigate a chimpanzee stone tool site in the Ivory Coast, where he found evidence in the archaeological record of repeated use of nut-cracking, evidenced by an accumulation of unintentional flaked stone tools and nuts. This brought implications for Human evolution as a whole, as this behaviour mimicked site formation as well as stone assemblages of early hominins. In a 2009 paper he found evidence of wild sorghum processing on tools through starch analysis from the cave site of Ngalue in Mozambique. This showed that early homo sapiens in Southern Africa were eating both above ground grasses as well as underground plant resources.
