Caleb L Geister

I am a Biological Technician in the Deepwater branch of the USGS Great Lakes Science Center.

I assist in the collection of fisheries data through the Large Vessel Program. My work encompasses both field and laboratory processes. My main focus in lab work is the aging process of predator and prey fishes of the Great Lakes.
