Currently living in Dublin, I work as a technical engineer in digital imaging. I obtained my BSc (hons) in Zoology from the University of Aberdeen and then my MSc in Microscopy and Image Analysis from University College Dublin. In my spare time I enjoy collecting and restoring antique microscopes and telescopes. Through this I have gained a great appreciation for the history and technology of imaging, which I hope to share through the writing I do for BSB. When not nerding it up I like to spend my time outdoors with my dogs.

Color Transmission Electron Microscopy

There are two types of electron microscopy—transmission electron microscopy (TEM) and scanning electron microscopy (SEM). SEM creates fascinating 2D images by bouncing electrons off the surface of the sample. I highly recommend searching for SEM samples on Google images. While SEM images are aesthetically amazing, the TEM images bring us inside the world of the…

Microscopy – a Numbers Game

While the microscope is synonymous with biology, it is a child of physics and technology. When we learn about the microscope we learn physics—specifically, we learn about optics. Many great resources are available that explain the inner working of microscopy. And, like most things in physics, the inner working of microscopes comes down to a numbers…

Halogen vs LED Lighting in Digital Microscopy

When it comes to light sources for microscopy, there is really no such thing as the “best.” The type of light source you use depends on the system you are working with and the type of result that you want. Digital systems are usually designed to work with either a halogen or a LED light…
