Mahima is a postdoctoral fellow with the Weed Science Research Group at The University of Adelaide. Her current research focus is on understanding the evolutionary dynamics of summer weed resistance to pre-emergent herbicides and genetic characterisation of 2,4-D herbicide resistance in wild radish, sow thistle and Indian hedge mustard.

"Mechanisms, evolution and inheritance of herbicide resistance" 2015-2018

"Understanding resistance to 2,4-D in common sowthistle and opportunities for improving 2,4-D activity on resistant populations" 2018-2020

"Assessment of phenotypic variation in glyphosate resistant populations of feathertop Rhodes grass and awnless barnyard grass in response to the K herbicide S-metolachlor (Group K/15) and saflufenacil + trifludimoxazin (Group G/14)" 2020-2025

"Target-site resistance to 2,4-D or other group I/4 herbicides in winter and summer weed species" 2020-2025
