Christian Krohn

Dr Christian Krohn is an early career researcher at RMIT University’s ARC Training Centre for the Transformation of Australia’s Biosolids Resource. His research explores how microbial ecology underpins the stability and efficiency of wastewater and biosolids treatment processes. Combining meta-omics, long-read sequencing, and time-series modelling, he develops diagnostic tools to link microbial community dynamics with methane yields, foaming, and digester health. Christian completed his PhD in Soil Science and Microbial Ecology at La Trobe University, where he investigated how soil microbial diversity mediates the breakdown of persistent organic pollutants. His work has produced 19 peer-reviewed publications (h-index 8) and attracted multiple institutional and national awards, including the Nancy Millis Medal and the C.G. Stephens Medal. He is an active science communicator, industry collaborator, and mentor, contributing to public engagement on the microbial foundations of a circular, low-emission bioeconomy.
