The aim of my research is to understand how coastal systems have been altered by both extreme events (storms, tsunamis) and gradual environmental changes over the Holocene. My objective is to extend the short-term instrumental record, and through this improved understanding of impacts and processes, enhance our ability to forecast how coastal systems will respond in the future. Many of the best reconstructions of coastal systems have been derived from sedimentary and paleontological proxies. Primarily I use sedimentary, mollusk, and microfossil evidence to better understand the paleo-record in a variety of coastal systems (temperate, tropical, and arid environments). My current research interests fall into, but are not limited to, three broad themes.

1) The application of microfossils in monitoring and reconstructing coastal environments and inland environments

2) The role of earthquakes, storms and tsunamis on coastal evolution

3) Human impact of coastal change

I am currently working on the foraminiferal assemblages in the 2018 Sulawesi tsunami sediments from Palu Bay, Indonesia. Looking at the foraminifera deposited by this recent event is useful in identifying potential records of past tsunamis from overwash sediments. These records provide insights to help us understand the variability in magnitude, frequency and impacts of past extreme events. Additionally, learning about the characteristics of past tsunamis gives context for current and future coastal vulnerability and coastal hazard assessments.

I am interested in the environmental aspect of Earth Sciences. This includes natural hazards, water resources, and climatology. I am currently pursuing an Honour鈥檚 thesis that involves identifying paleo-tsunami deposits in Hawke鈥檚 Bay, New Zealand using grain size data and geochemical analysis with X-ray fluorescence.

My research interests involve using microfossils (e.g., foraminifera) and sediment grain size to reconstruct coastal environments. Specifically, I am interested in using these techniques to identify tsunami deposits in the geological record.

The aim of my research is to understand tsunamis affecting the Sendai coast ofJapan. Using a microfossil called foraminifera, I am trying to determine the sediment provenance ofthe 2011 Tohoku-oki tsunami event. With this information, future studies can compare the sediment provenance to paleotsunamis uncovered in the same region to try and better understand differences inregionaltsunami intensity. Understanding the tsunami record can help communities along coastlines prepare for future inundation events.

I'm a second year masters student at the University of Southern Mississippi in the Marine Science, Geological Oceanography program. My research investigates post depositional change of tsunami deposits laid down during the 2004 Indian Ocean Tsunami on the north-western coastline of Sumatra, Indonesia. The tsunami deposits contain distinctive marine material, including foraminifera, that can be indicative of marine provenance when found within anomalous sand layers in low energy terrestrial environments. I recognize post-depositional change by looking at foraminiferal taphonomy overtime. Conclusions from this study will allow for a more robust framework with which to investigate tsunami deposits and offer caveats when considering post depositional change.
