The Matthews Lab works on a range of animals and plants, and uses a range of imaging techniques, including microscopy and time-lapse photography, for visualizing biological processes. A sample of videos and photos showing work done in the lab can be seen here

Videos

Co-flow microfluidic chip producing droplets of PDMS silicone as the starting point for manufacturing implantable fluorescent O2 sensors

Time-lapse video showing the embryonic development of four-spot skimmer dragonflies (Libellula quadrimaculata) from 2 hours after the eggs were laid until pre-hatch (4 days in total). Darkfield microscopy

Time-lapse video showing a thermogenic flower of Victoria cruziana water lily opening at sundown. These flowers bloom only at night, with each flower opening twice over two consecutive nights. This flower is opening for the first time. It is in its female stage and is ~8 °C warmer than the surrounding air. (Filmed at the University of Stellenbosch Botanical Gardens, Stellenbosch, South Africa)

Time-lapse video showing a flower of the Victoria cruziana water lily opening at sundown on its second night of flowering. It is at most a couple of degrees warmer than the surrounding air. It is now in its male phase with the stamens shedding their pollen. (Filmed at the University of Stellenbosch Botanical Gardens, Stellenbosch, South Africa)
