Monaliza's primary research interest lies in marine ecology, with a focus on plankton ecology and biological oceanography. She has also extended her research towards marine pollution, particularly related to water eutrophication and hypoxic environments, for prediction, management, and mitigation of Harmful Algal Blooms (HABs). Monaliza is also working on marine toxicology related to toxin-food safety produced by toxic microalgae and pufferfish. Currently, she is exploring the application of environmental DNA (eDNA) as a monitoring tool for aquatic population dynamics, ecological monitoring, and ecosystem assessment. She is an expert in marine and freshwater plankton identification at the genus and species level, as well as enumeration and analysis of plankton diversity indices for ecological studies. During her doctoral studies, Monaliza utilized next-generation molecular tools, such as 18S rDNA metabarcoding, to investigate the diversity and distribution of HAB species in eutrophic marine ecosystems. Furthermore, she investigates the effects of eutrophication-related drivers and hypoxia as an ecological marine disaster.
