Seeing greening better than the eye can

Today we were working with Ed Etxeberria and Pedro Gonzalez on a camera developed by a group of engineers at UF.  The camera uses polarized light filters to filter for starch, which accumulates in leaves affected by huanglongbing.  The camera was intended for use as a remote sensing application, but we are attempting to use it on a small scale to detect the very early onset of HLB symptoms in our studies without destroying leaves to test for the bacterium that causes it.

Citrus cosmetics

Working today on project to trace the initial stage effects of CLas, the bacterium thought to cause citrus greening.  To do this we have to find a way to get the psyllids in the cage ↓ to bite in just one spot.

To do this, along with Ed Etxeberria, we’re testing what materials we can cover the leaves with to prevent psyllid bites in some areas without spoiling their appetite for the part that is exposed.

Student Mentorship

Mentoring is broad, but in my case it includes everything from training my newer colleagues in methods of production or laboratory methods, editing and commenting on their writing, advising them on statistical analyses, or even just how to deal with challenging courses.
