Dr Ioanna Kalantzi is a post-doctoral researcher in the Hellenic Centre for Marine Research (HCMR) – Institute of Oceanography. She holds a PhD in Environmental Chemistry (2013) from the Biology Department (University of Crete) and an MSc in Environmental Sciences (2004) from the Environmental Engineering Department (Technical University of Crete) and a bachelor in Chemistry (2002). Her work has contributed to the understanding of the human risk assessment through the consumption of seafood and the bioaccumulation, bioavailability and trophic transfer of contaminants, such as metals, elements, POPs, and nanoparticles, in the marine environment and in marine organisms, and the aquaculture ecosystem interactions. 
She has been involved in 24 RTD projects (12 national and 12 EU funded) focused on the anthropogenic impacts on the marine environment, the marine organisms, the human nutrition and the atmosphere and on the interactions of the environment with aquaculture, such as Water Framework Directive, AQUACOSM, TAPAS, POSEIDOMM, AQUA-NANO. 
Results of her work have been published in 28 international peer reviewed journals (2 more are under review), and in several conference presentations and posters. Her h-index is 14 and the citations on her work are more than 650 (Scopus, 15/03/2022). 
She was the Principal Investigator of the JERICO-NEXT Transnational Access to Coastal Observatories (EU) project: ‘Monitoring of Organic Contaminants in the water of the Southern Europe with Passive Sampling’. Currently, she is the Principal Investigator and Coordinator of the MetaFRisks project which is funded by the Hellenic Foundation for Research and Innovation (HFRI) under the “2nd Call for H.F.R.I. Research Projects for the support of Post-doctoral Researchers”.

To this end, she has focused on the development of quantitative analytical methods for total metal determination and speciation of metals in environmental samples by the use of ICP-MS. Moreover, she has participated in activities for the determination of other impacts on marine ecosystem, for the implementation of Water Framework Directive and for the estimation of the impact of important pressures (e.g. nanoparticles) on the marine environment.

She has also participated in numerous oceanographic research campaigns in national and international marine research projects.
