MicroGen Biotech R&D Team

Our R&D team has over 30 years of experience in bioremediation of pollutant impacted soil and promotion of crop health and yield through microbial-plant-soil interaction. Our core team had over over 70 international peer reviewed publications and over 200 conference and technical publications including presentations, posters and conference proceedings including cover on Nature Biotechnology. We also have Patents on our technologies and products both in Ireland and China.

Dr. Kieran Germaine has over 15 years of experience in both research and industry focusing on bioremediation. He has led a number of large scale PAH and TPH bioremediation projects in Ireland and China.



Daniel Dowling has a BA in Natural Sciences from Trinity College Dublin and a Higher Diploma in Business Management from IT Carlow. He continued his education with a MSc in Evolutionary Biology from the University of Bonn (Germany) and a PhD from the University of Münster (Germany) specialising in bioinformatics and the evolution of novel protein-coding genes.



Dr. Madigan has a strong microbiological background. In the past decade, he was awarded a research MSc relating to forest pathology in Scotland followed by a PhD associated with the soil microbiome in Australia. He subsequently conducted postdoctoral research related to soil carbon dynamics in Ireland.



In 2016 Junyan Zhang obtained a masters degree of engineering majoring in biochemistry from  Tianjin University.  Since then Junyan has been working in Maikezhen company, and is responsible for laboratory research and development and related management.


2014-2017, Wenguan Zeng graduated from Shandong Agricultural University with a master’s degree in Crop Genetics and breeding.
Since 2017, he has been working as a product verification and other research and development issues in Microgen. Presently he also holds the position of deputy general manager.


Prof. Vangronsveld had published over 250 peer-reviewed papers mainly in the area of phytoremediation of soil and groundwater contaminated with heavy metals, BTEX, TCE, petroleum hydrocarbons and explosives. His research focus is on combining fundamental studies of plants and microorganisms in order to optimize remediation of real-world sites (e.g. Ford Motor Co., Belgian military sites). He deploys traditional plant and microbial biological techniques in combination with next generation sequencing technologies and modern analytical tools to enhance remediation outcomes.



Professor Rafael Rivilla is our scientific advisor. He has 25 years experience in the area of plant-microbe Interactions, environmental regulation of motility and biofilm formation, biocontrol and pseudomonas genetics and genomics. He has also coordinated several multi-million euro EU projects with industries and third level researchers.



Professor Yiping Wang is the director of gene regulation and microbe functional genomic laboratory in Peking University,China. He is an international pioneer in nitrogen fixation research with over 80 peer reviewed publications. Prof. Wang is also the chief scientist of the “973” Development Plan of the Chinese State Key Fundamental Research in developing sustainable environment and agriculture.
