Assoc Prof Aravind Babu DasariDr Dasari’s major research emphasis is on the development of in-depth understanding of the various facets of processing-structure-property relations in hybrid polymer nanocomposites to achieve synergistic properties for different end applications. These facets include: 1. Thermal stability and flame retardancy (with eco-benign agents) 2. Functional properties (electrical/thermal conductivities, biodegradability and UV shielding) 3. Electrospinning techniques 4. Wear/scratch damage at different scales (macro/micro/nano) 5. Deformation and Fracture mechanisms 6. Active food packaging

Prof David WardleDavid Wardle’s research explores the links between aboveground and belowground communities, and how these in turn drive the functioning of terrestrial ecosystems. A large proportion of this work is field based and in natural ecosystems, including in forested ecosystems around the world as well as subarctic and subalpine tundra. Current projects focus on the community and ecosystem effects of invasive animals and plants; the ecological consequences of wildfire; ecosystem changes across successional, retrogressive and elevational gradients; aspects of island ecology; and the ecological role of forest understory vegetation.

Asst Prof Faizah Binte ZakariaI am currently working on a book manuscript based on my PhD dissertation titled, "Spiritual Anthropocene: Ecology of Conversion in Maritime Southeast Asian Uplands." The book is under contract with University of Washington Press (anticipated publication, 2021). My project uses the North Sumatran highlands as a case study to examine how mass religious conversion from animism to monotheism was catalyzed by the transformation of the environment as well as large- scale migration working as a holistic system embedded in global networks. I am building on this research to develop a monograph that demonstrates how religious beliefs about the natural world have a dialectical impact on environmental management due to this interconnected global network. Of central interest are the following questions: how do religious beliefs shape a maritime Southeast Asian environmentalism? Conversely, how do changes to our local environments impact religious thought? The project will also further interrogate the idea of the Anthropocene to examine how the concept goes beyond geology and material landscapes as well as time by factoring in how sacred landscapes overlay natural ones. With support from various grants, I am also developing new projects on the history of charismatic megafauna as well as multi-faceted, long-term impacts of volcanic eruptions in the Southeast Asia region. More broadly, my research interests sits at the nexus of history and anthropology, including: world and imperial history, indigenous peoples and religions, environmental justice and sustainability, mass violence, human rights and the Anthropocene.
