holds a BSc in Earth Science and MSc in Geology from the University
of Bern (Switzerland).
She graduated in 2008 with a thesis on climate variability recorded in a
50,000-years old stalagmite from Northern Turkey. Before
starting her university studies Heidi worked as laboratory assistant in biology
and environmental science, (1989-2002). Her interest in Geology and cave
research rose from several years caving in Switzerland.
Heidi joined the Palaeoclimate Research Group in UCD in 2008 as a PhD student,
studying Irish speleothems to reconstruct the climate variability in the last glacial

PhD project title: Climate variability during the last glaciation investigated by Irish
speleothems (working title)
Supervisor: Prof. Frank McDermott
Several uranium-thorium dated speleothems from Crag cave S.W. Ireland, indicate sporadic speleothem deposition between 131.51 ± 0.56 ka and the Holocene. The new data constrain for the first time in an Irish terrestrial record the timing and duration of short-lived warming events (Dansgaard-Oeschger events) during the last glaciation. Stable oxygen and carbon isotopes give further insights into these warm intervals. Cold time periods and especially Heinrich events are indicated by non-deposition of speleothems.
A key component of the PhD work was to establish the U-series method in the UCD laboratories including chemistry protocols, spike calibration, optimising of measurement conditions (Thermo Fisher Neptune with Airdus II Desolvating Nebulizer System), data reduction and age calculation.
