Associate Professor Alan Hogg
Qualifications: MSc DPhil Waikato
Assoc. Prof. Alan Hogg is the Director of the Waikato Radiocarbon Dating laboratory. He is recognised as an international authority on radiocarbon tree-ring dating, including development of the Southern Hemisphere (SH) 14C calibration curve, SHCal13 (Hogg et al. 2013a) allowing accurate calendar ages to be derived from SH 14C determinations.
Current research centres upon 14C calibration and palaeoclimate as well as 14C wiggle matching. Alan was lead researcher on a large international study measuring atmospheric 14C in Younger Dryas (~12,950 - 11,600 years ago) tree-rings (Scientific Reports, 2016; Radiocarbon, 2016). He also led a study to obtain precise calendar ages for North Island pā, by 14C wiggle matching preserved palisade posts (Journal of Archaeological Science: Reports, 2017). Other research has established the timing of arrival and impacts of Māori in New Zealand and 14C dating the key tephra marker beds, the Kaharoa, Taupo and Kawakawa/Oruanui Tephras.
