A long-standing research area primarily concerned with computer simulation of the growth and movement of problem cyanobacterial blooms and strategies for their management.
I have been interviewed several times for ITV and BBC news following outbreaks of toxic blue-green algae affecting waterbodies, such as lakes and rivers used for recreation and/or fishing.

- In the past decade, scientists have paid more attention to studying light harvest for producing novel bionic materials or integrating naturally biological components into synthetic systems. Tehir inspiration is the imitation of natural photosynthesis in green plants, algae, and cyanobacteria to convert light energy into chemical energy. Photosystem II (PSII) is a light-intervened protein complex […]
- An international study led by Helmholtz Zentrum München has revealed the structure of a membrane-remodeling protein that builds and maintains photosynthetic membranes. These fundamental insights lay the groundwork for bioengineering efforts to strengthen plants against environmental stress, helping to sustaining human food supply and fight against climate change.
- While invasive zebra mussels consume small plant-like organisms called phytoplankton, Michigan State University researchers discovered during a long-term study that zebra mussels can actually increase Microcystis, a type of phytoplankton known as "blue-green algae" or cyanobacteria, that forms harmful floating blooms.
- Lake Victoria, which came under the spotlight in 2004 by the documentary "Darwin's Nightmare," is not only suffering from the introduction and commercialisation of the Nile perch. A study lead researchers from the University of Liège (Belgium) has highlighted other worrying phenomena, particularly climatic ones, which have an equally important impact on the quality of […]
- A new study conducted by the researchers at the University of Liverpool reveals how the ancient photosynthetic organisms—cyanobacteria—evolve their photosynthetic machinery and organise their photosynthetic membrane architecture for the efficient capture of solar light and energy transduction.
- Taking action on phosphorus in Lake Champlain would bring tens of millions in dollars in benefits to Vermonters, researchers say.
- Certain cyanobacteria can change the absorbing light colors for photosynthesis using a green- and red-light sensing photosensor protein. A Japanese research group elucidated the molecular structure of RcaE, a representative member of the photosensors. They revealed the unique conformation of the bilin chromophore and the unique protein structure that potentially functions as a proton transfer […]
- Oxygen levels in the world's temperate freshwater lakes are declining rapidly—faster than in the oceans—a trend driven largely by climate change that threatens freshwater biodiversity and drinking water quality.
- Carbonic anhydrases are essential enzymes that are present in virtually all living things; all eight classes of carbonic anhydrases that have been identified to date need a metal ion to function. But now, researchers from Japan have discovered that metal is not crucial for all carbonic anhydrases.
- Rubisco is arguably the most abundant—and most important—protein on Earth. This enzyme drives photosynthesis, the process that plants use to convert sunlight into energy to fuel crop growth and yield. Rubisco's role is to capture and fix carbon dioxide (CO2) into sugar that fuels the plant's activities. However, as much as Rubisco benefits plant growth, […]
