Research Interests

Fungi play an important role as integral part of our ecosystem. They are source of food as raw material as well as fermentation products and enzymes. Furthermore, they produce bioactive secondary metabolites including food contaminating mycotoxins (e.g. aflatoxin, sterigmatocystin, fumonisins), antibiotics (e.g. penicillin, cephalosporin) and many other pharmaceuticals have great impact on human activities on earth. Our research focuses on detrimental and beneficial features of fungi. We try to prevent detrimental features of fungi such as mycotoxin production and contaminating food sources while we try to enhance beneficial features such as enzyme production, pollutant degradation using our expertise of molecular biology and fungal physiology. We have been working with a number of fungal organisms including model filamentous fungus Aspergillus nidulans, opportunistic human pathogen Aspergillus fumigatus, plant pathogen and aflaxotin producer Aspergillus flavus, model organism Neurospora crass, model system yeast Saccharomyces cerevisiae. In addition to these filamentous fungi and yeast, we have also established expertise for mushrooms to cultivate these organisms for enzyme and biomass production.

Our research has got more than 5,250 citations according to the Google Scholar, and many of our papers are available as open access and in platforms like Researchgate. We have been collaborating with leading researchers from countries, Macau, Brazil, USA, Austria, Germany, Japan and Korea. We are expert in discovering protein complexes that regulate fungal secondary metabolite production. We have published landmark papers in regulation of mycotoxins. Transcriptional regulatory complexes, velvet complex (Science) (Genetics), Epigenetic Methyltransferase Complex, (Developmental Cell), COP9 complex (PNAS), the MAPK complex, the STRIPAK complex, F-box proteins and SCF complexes (PLoS Genetics), Fbx15 complex (PLoS Pathogens) the chromatin binding KERS complex (Nucleic Acids Research), Gliotoxin regulatory complex (Nature Communications) are few to name.

Our papers have been highlighted by a variety of national as well as international science and technology news agencies including Science News (USA), Irish Times (Ireland), Siliconrepublic (Ireland), EurekAlert (USA), newsWise (USA), AZO Life Sciences (UK) Phys (UK).

Our major research interest include:

  • Understanding mycotoxin production of fungi using molecular biology and epigenetic tools.
  • Reducing mycotoxins in food and feed sources for food safety and security.
  • Use of fungal enzymes for bioremediation of pollution.
  • Use of fungal biomass production.
  • Using fungi and fungal enzymes for circular economy

We will be organising Europes largest Fungal Genetics Conference, 17th European Conference on Fungal Genetics (ECFG) in Dublin, Ireland in March 2025. We encourage all fungal researchers and plant pathologists working with fungi to participate in 17th ECFG.

NURoFE_MSCA IF EF ST_LEANDROASSIS PI The dependence of mankind on petroleum- and oil-based fuels as the main energy source is widely recognised as being accompanied by several problems that impact the global economy and environmental health. In recent years, the conversion of plant biomass to biofuels, in a process called 1st- (1G) and 2nd-generation (2G) biofuel-production, has gained significant interest as an environmentally friendly and naturally abundant alternative, renewable energy source. The EU (European Union) legislation implements that by 2020, 20% of energy must be derived from renewable sources, showing the importance that renewable energy source production will play in the future. Saprobic microorganisms, such as filamentous fungi of the genus Aspergillus, are of particular interest for this process as they secrete a vast array of plant biomass hydrolyzing enzymes. A major drawback in the production of renewable biofuels is built-up of glucose during enzymatic hydrolysis of plant biomass, resulting in the transcriptional repression of fungal enzyme-encoding genes and subsequent secretion. The here described fellowship is proposing to uncover novel proteins involved in the regulation of hydrolytic enzymes and secondary metabolites production in the filamentous fungus Aspergillus nidulans that can be explored for biotechnological processes. To implement this project, the candidate will be hosted at the National University of Ireland in Maynooth in the laboratory of Fungal Genetics and Secondary Metabolism, under the supervision of Dr. Ozgur Bayram. 26/05/2021 25/05/2023 196590.72
