Gernon obtained his B.Sc. (Hons) in geology from University College Dublin, and obtained a Ph.D. in Earth Sciences from the University of Bristol (with Prof Sir Steve Sparks). He held postdoctoral positions at the University of Bristol from 2007-2008 where he worked on the geology of the Snap Lake kimberlite, Arctic Canada. After a period as Lecturer in Geology at Trinity College Dublin (2008 to 2009), he joined the University of Southampton as Lecturer (Assistant Professor) in Earth Science, and was promoted to Associate Professor in 2016, and Professor in 2023. He was named a Turing Fellow in 2018, and again in 2021. He has led or co-authored over 70 peer reviewed papers in international scientific journals including Nature and Science and has delivered over 50 lectures at international conferences, workshops, seminars and public talks.

Elected Fellow, UK Higher Education Academy

Southampton undergraduate teaching: Structural Geology (coordinator), Volcanic and Mantle Processes (lecturer and fieldtrip co-leader), and Independent Mapping (coordinator). During the Covid-19 pandemic, I developed an interactive online course on physical volcanology, and coordinated an innovative hybrid geospatial mapping exercise for our undergraduate students to give them the best possible experience. I have also contributed to teaching Dynamic Earth, Earth Materials, Geohazards & Earth Resources, and Advanced geological field skills (coordinator).

2008 - 2009

Trinity College Dublin undergraduate teaching: Global Igneous Petrology, Geochemistry (coordinator), Field Geology (coordinator) and Broad Curriculum Geology (coordinator)
