Research Overview

I study how reef systems and sea level have changed through time by pairing high-precision U–Th geochronology, carbonate geochemistry, and coral proxy records with transparent, Python-based workflows. I’m especially interested in extracting seasonal to multi-decadal signals (e.g., ENSO) from coral archives and improving chronologies in challenging materials such as meteoric calcite within altered fossil corals.

Research Focus

Coral core and slab used as paleoclimate archive Coral Paleoclimate Archives

Seasonal to multi-decadal reconstructions from coral trace elements and isotopes (e.g., Mg/Ca, Li/Mg) measured by LA-ICP-MS and complementary tools.

U–Th preparation and instrumentation U–Th Geochronology

High-precision dating of carbonates, including meteoric calcite phases in altered fossil corals, to refine Holocene sea-level histories.

Analytical setup for trace-element and REE workflows Method Development

Instrument optimization, standards and QC design, and REE/trace-element workflows at ultra-low levels with reproducible data-reduction notebooks.

Current Projects

Altered fossil coral showing meteoric calcite Sea Level from Meteoric Calcite

U–Th dating of meteoric calcite in highly altered fossil corals. Trace-element screening, micro-sampling, and open-system checks improve chronologies and reduce uncertainty.

Time-series concept for ENSO signals in coral geochemistry ENSO from Coral Proxies

LA-ICP-MS Mg/Ca and Li/Mg time series with seasonal removal and anomaly detection toward consistent metrics of ENSO amplitude and frequency.

Mid-Holocene coral slabs and laser sampling, Heron Reef Mid-Holocene Coral Paleoclimate (Heron Reef)

Two ~60-year snapshots at ~6.9 and 5.2 ka from fossil corals. Laser profiles of Mg, Sr, Mn, and REEs test ENSO and monsoon behavior and link climate swings to coastal water quality.
