My original research area was primarily concerned with computer simulation of the growth and movement of problem cyanobacterial blooms and strategies for their management. I was lucky to work with colleagues such as Colin Reynolds at the Institute of Freshwater Ecology in Windermere and mentors Pauline Kneale, Mike Kirkby and Adrian McDonald at Leeds. My PhD students including Basak Guven and Mark Easthope carried this work forward and have excelled in their own careers.

- Huge pink flocks of millions of flamingos—flamboyances of flamingos—are one of nature's great spectacles. But colleagues and I have uncovered worrying trends in the salty and highly-alkaline "soda lakes" of east Africa where most of these birds live.
- Plenty is known about the existential threat of climate change to plants and animals. But by comparison, we know very little about how microorganisms will be affected by climate change.
- The sea is the world's largest ecosystem, and it harbors two photosynthetic organisms that produce approximately half of the oxygen on Earth. The cyanobacterium Prochlorococcus is the most abundant photosynthetic organism in the oceans and fixes approximately 4 gigatons of carbon each year, comparable to the net global primary production of the world's agriculture industry.
- Cyanobacteria—also called blue-green algae—are known as the "plants of the ocean" because they carry out photosynthesis on a gigantic scale, produce oxygen and extract the greenhouse gas CO2 from the environment. However, to do this they need additional nutrients such as nitrogen.
- Nitrogen is a nutrient essential for all life on Earth. Although nitrogen gas (N2) is plentiful, it is largely unavailable to most organisms without a process known as nitrogen fixation, which converts dinitrogen to ammonium—a major inorganic nitrogen source.
- A research team at Friedrich Schiller University Jena, Germany has now found a bacterium that forms a team with a green alga. Both microorganisms support each other in their growth. Additionally, the bacterium helps the microalga to neutralize the toxin of another, harmful bacterium. The fundamental understanding of algal-bacterial interactions also plays an important role […]
- One ecosystem's trash could be another ecosystem's treasure, according to scientists studying cyanobacteria, more commonly known as blue-green algae.
- Phytoplankton is the primary energy source for all marine ecosystems: These tiny plants floating in the seawater use photosynthesis to bind energy in the form of biomass, which is then passed on step by step in the marine food webs all the way to different types of fish and piscivores.
- Microalgae, including cyanobacteria and green algae, represent the most important biological systems for producing biomass and high-value products. It is estimated that microalgae can fix about 90 billion tons of carbon dioxide per year, which accounts for more than 40% of the global net photosynthetic carbon fixation.
- Iron ore is a big deal in Australia.
