The Doctor of Philosophy serves as our primary research-based degree. To earn a PhD, candidates must submit a substantial thesis (approximately 300 pages or 100,000 words) that demonstrates original discoveries, interpretations, and communication of new knowledge. This research should meet publication standards in respected international and national peer-reviewed journals, representing work achievable by a dedicated student within three to four years of full-time study (or five to seven years for part-time or split-site programs). Examiners also assess the candidate's comprehensive understanding of their research field.
This program examines pivotal moments in Earth's history through collaborative research involving geochemists, paleontologists, and climate modelers. Key areas of investigation include analyzing mass extinction events, studying the chemical evolution of ocean-atmosphere systems and their connection to biological development, reconstructing ancient ecosystems and biodiversity patterns, and exploring historical climate dynamics.
