Introduction
I am a geoscientist studying the influence of arc-continent collisions on carbon sequestration. I examine the effects of rapidly uplifting orogens in mid-latitude regions, and the competing influence of silicate weathering versus enhanced nutrient supply and marine productivity. I employ multidisciplinary methods in my research, integrating geochemistry, sedimentology, and statistical modeling to better understand these complex processes.

An investigation of allogenic forcings on shallow‐marine strata of the Miocene–Pliocene Kueichulin Formation, Taiwan Western Foreland Basin, reveals that shifts in palaeoenvironments were strongly controlled by: (1) orogenesis and basin subsidence, (2) precession‐driven hydroclimate and (3) obliquity‐driven atmospheric and ocean circulation. Shifts...
Late Cenozoic changes in the intensity of the East Asian Summer Monsoon (EASM) are reconstructed using both terrestrial and marine proxy records; however, proxies from terrestrial (e.g., loess, pollen, and pedogenic isotopes) and marine environments (e.g., foraminifer assemblages and geochemistry) commonly display large discrepancies both in the di...
Climate oscillations preserved in sedimentary archives tend to decrease in resolution further back in Earth's history. High‐frequency climate cycles (e.g., ∼20‐Kyr precession cycles) are especially prone to poor preservation due to sediment reworking. Recent studies have shown, however, that given sufficient basin accommodation space and sedimentat...
Storm-flood-dominated deltas are sedimentary systems in which a complex interplay of hydrodynamic processes occurs during storms (e.g. tropical cyclones) due to the coeval action of continental and oceanic processes. This paper reports on a superbly exposed, 135.5 m thick stratigraphic succession of the Pleistocene Cholan Formation exposed along th...
The appraisal of sedimentary archives is key for predicting sea level changes and extreme weather event behavior under varying greenhouse gas levels. Here, we assess the hydroclimate variability of the northwest Pacific realm during the Pliocene-Pleistocene transition by using a continuous record of gamma-ray log data from two boreholes comprising...
The Taiwan Western Foreland Basin is thought traditionally to have received sediment mainly from Eurasia until the late Pliocene-early Pleistocene, after which time, the Taiwan orogen became the dominant source. However, a combination of clay mineralogy, δ 13 C org and C/N of organic matter, and mass-specific magnetic susceptibility of late Miocene...
Collision between the Philippine Sea Plate and the Eurasian Plate in the late Miocene-early Pliocene resulted in the uplift of Taiwan, and lithospheric flexure to the west formed the adjacent Western Foreland Basin (WFB). Petrographic studies of late Miocene to Recent sediment and sedimentary strata in the WFB indicate that Taiwan was the main sedi...
Variations in bed- and bedset-scale permeability in bioturbated siliciclastic rocks result in heterogeneity that is difficult to model at a reservoir scale. This paper presents a technique to upscale permeability, such that the permeabilities of the bioturbated zones are explicitly included in the upscaled values. Study of 28 cored wells of the Low...
Facies-scale trends in porosity and permeability are commonly mapped for reservoir models and flow simulation; however, these trends are too broad to capture bed and bed-set heterogeneity, and there is a need to up-scale detailed, bed-scale observations, especially in low-permeability reservoir intervals. Here we utilize sedimentology and ichnology...
The majority of naturally occurring freshwater on small islands is groundwater, which is primarily recharged by precipitation. Recharge rates are therefore likely to be impacted by climate change. Freshwater resources on small islands are particularly vulnerable to climate change because they are limited in size and easily compromised. Here we have...
Bioturbation is generally perceived to be detrimental to bulk permeability by reducing primary grain sorting, homogenizing sediment, and introducing mud as burrow linings and feces. Recent studies show, however, that some ichnogenera and biogenic fabrics can serve to increase porosity and permeability. In tight oil and gas reservoirs, subtle change...
