Key research themes
1. How does iron deficiency influence eukaryotic translation and what molecular mechanisms mediate this effect?
Research investigates the role of iron as an essential cofactor for enzymes involved in translation in eukaryotic cells, especially how iron deficiency impairs translation initiation and regulation, focusing on yeast as a model organism. Understanding these mechanisms is vital for insights into cellular adaptation to iron deprivation and the broader implications for human health and disease.
2. What are the advancements and challenges in leveraging iron for sustainable low-carbon energy technologies?
This research theme explores iron's applications in emerging energy technologies such as combustion fuels, iron-based batteries, and thermochemical cycles for hydrogen production, alongside sustainable methods for iron production and recycling. These investigations address iron's potential to contribute to decarbonization and energy storage, balancing economic feasibility and environmental impact.
3. How has the innovation, adoption, and spread of iron metallurgy influenced socio-political and economic systems in the ancient Near East and Eurasian steppes?
Research focuses on archaeological, textual, and metallurgical evidence tracing iron's origins, spread, and socio-economic impacts in ancient societies. It distinguishes technological innovation phases from broader adoption and usage patterns, emphasizing the relationship between material properties, social context, and empire formation, with particular attention to the Mongolian Plateau and the Xiongnu Empire's role in advancing iron metallurgy.
4. What molecular interactions govern the binding and speciation of Fe(II) and Fe(III) with organic matter and mineral interfaces, and how do these affect corrosion and environmental transport?
This theme encompasses studies on iron speciation at interfaces like iron-cement and its complexation with organic matter, especially humic substances, which influence iron corrosion products formation, retention, and mobilization. Such knowledge is crucial for applications ranging from concrete durability to contaminant transport modeling and biogeochemical cycling.
