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.

- Biological membranes play important roles in shaping the cell, sensing the external environment, molecule transport, and generating energy for life. One of the most significant biological membranes are the thylakoid membranes produced in plants, algae and cyanobacteria, which carry out the light reactions of photosynthesis.
- A billion years ago, a single-celled eukaryote engulfed a cyanobacterium—an organism capable of converting the sun's energy into food in the form of carbohydrates. In one of the single most pivotal events in the history of life, instead of the bacterium being digested, an endosymbiosis was formed, with the bacterial cell persisting inside the host […]
- Scientists from the University of Liverpool have revealed new insight into how cyanobacteria construct the organelles that are essential for their ability to photosynthesise. The research, which carried out in collaboration with the University of Science and Technology of China, has been published in PNAS.
- Algae hold a lot of untapped potential for use in industry. So far algae have provided invaluable nutrition in the health food sector but have struggled to be competitive against petroleum-derived chemical production. Algae are more favorable to petroleum from an environmental standpoint but the production cost of culturing, collecting, extracting and refining adds up […]
- Cyanobacteria, commonly referred to as blue-green algae, are the first organisms on earth that learned to extract electrons from water and convert sunlight to usable energy through photosynthesis. Using cyanobacteria as a model organism, the details of photosynthesis—the key process that supports all forms of advanced lives on earth—have been studied for many decades. And […]
- Biological builders like beavers, elephants, and shipworms re-engineer their environments. How this affects their ecological network is the subject of new research, which finds that increasing the number of "ecosystem engineers" stabilizes the entire network against extinctions.
- Cyanobacteria hardly need any nutrients and use the energy of sunlight. Bathers are familiar with these microorganisms—often incorrectly called "blue-green algae"—as they often occur in waters. A group of researchers at the Karlsruhe Institute of Technology (KIT) has discovered that the multicellular species Phormidium lacuna can be genetically modified by natural transformation and could thus […]
- Reservoirs in the heart of an ancient Maya city were so polluted with mercury and algae that the water likely was undrinkable.
- Heading to the lake this summer? While harmful algal blooms can cause health problems for lake visitors, satellite data can provide early detection of harmful algae, resulting in socioeconomic benefits worth hundreds of thousands of dollars from one harmful algal bloom event, a new study finds. A Resources for the Future (RFF) and NASA VALUABLES […]
- Science fiction came up with machine-intelligent hunter drones and they have now become science fact with a new HKU-codeveloped autonomous 'hunter drone' that seeks out targets at night using a scanning laser.
