Staff Profile

Dr Samuel Logan

Plant Research Team Leader/Deputy Technical Manager


My background is in plant population genetics. However, I have a broad range of interests including ecology and conservation, plant biology, biodiversity, ornithology and entomology. I have been involved in plant research at Newcastle University since 2012.

In my current role I lead the plant research technical team providing support to the School's plant research projects. I oversee the plant research labs and growth facilities on campus and the greenhouse and plant trials at Cockle Park farm. I manage the long-running Palace Leas Hay Meadow Trial and run the Elementar Vario Macro Cube.

I work on population genetics research of Tilia (lime trees) from the UK and across Europe, and from western Siberia. We currently use microsatellite markers to discriminate between species, hybrids, and clonal cultivar groups.

We tested for the first time 13 markers to discriminated between the species and hybrid, and we assessed the population genetic diversity of the two UK species, T. cordata and T. platyphyllos, (Logan, Phuekvilai and Wolff, 2015). We have highlighted the within-population genetic diversity of the rare Siberian lime (T. sibirica) and proposed a putative Pleistocene split from the small-leaved lime (Logan, Chytry and Wolff, 2018). We have assessed genetic diversity, relatedness, clonal reproduction, and range effects of two European species (Logan et al., 2019). Tilia research in our lab is on-going and we continue to work with collaborators from American (Conover et al., 2019) and European Universities.
