4D SPIM (Selective Plane Illumination Microscopy)
Developing zebrafish lateral line (a sensory organ analogous to the mammalian inner ear that senses water movements in the fish). This organ develops from a primordium that starts migrating and deposits a group of cells called neuromasts, that contain mechanosensory hair cells and support cells. A combination of transgenic lines was used to label undifferentiated and support cells (membrane Tomato) and track hair cell development (cytoplasmic GFP) for 36 hrs.

Oil film floating on water

Thin film of volatile oil floating on a water surface. Evaporation occurs in isolated pools a few microns deep. Flow instabilities at the edges bring oil into the centers of the pools, forming droplets. Coalescence leads to bigger drops that have more volume per unit of surface area, and slower evaporation. Interference colors dramatize the motions. The complex microscopic fluid dynamics are relevant to the longevity of fuel spills.

Paul Maddox
Assistant Professor and William Burwell Harrison Fellow University of North Carolina at Chapel Hill, Department of Biology
Paul S. Maddox, Ph.D. is an Assistant Professor and William Burwell Harrison Fellow, Department of Biology, University of North Carolina at Chapel Hill, North Carolina, USA. Dr. Maddox completed his Ph.D. under the mentorship of renowned cell biology microscopist E. D. Salmon at the University of North Carolina at Chapel Hill. His current research interests include using light microscopy to understand chromosome and microtubule dynamics. Dr. Maddox’s experimental philosophy mandates using the light microscope to “see” results in the most quantitative manner possible. Dr. Maddox has over 19 years of experience with light microscopy and has been an instructor in light microscopy courses around the world including Europe, South America, and at the Marine Biological Labs in Woods Hole, USA. He has published over 60 peer-reviewed papers in his career.
