I am a geographer and engineer interested in understanding land change as coupled human-natural systems, with an aim to develop solutions to address sustainability challenges in Southeast Asia.
Presently, I am the Global Head of Remote Sensing and Geospatial Analysis at ClearWind, a Singapore-based company developing nature-based carbon projects across Southeast Asia.
Previously, I was a senior researcher at the National University of Singapore (2016–2023), most notably at the Centre for Nature-based Climate Solutions where I led, managed, and coordinated its regional Carbon Market Integrity R&D programme in Southeast Asia.
Prior to joining academia (c. 2000–2015), I was a conservation practitioner-scientist and worked with international, national, and local conservation organisations including Fauna & Flora International, Foundation for the Philippine Environment, and Haribon Foundation.
I am a member of the Global Land Programme, Biodiversity Conservation Society of the Philippines, Philippine Geographical Society, and a science team member of the ALOS Kyoto & Carbon Initiative, an international research collaboration led by Japan Aerospace Exploration Agency.

In Southeast Asia, we found that existing rubber plantations were being converted to oil palm, with 1.9% and 2.6% for Indonesia and Malaysia, respectively—this conversion was estimated at 10500 ha per year.
Here, we applied Emergent Threat Analysis a process—integrating Emerging Hot Spot Analysis of deforestation, visual classification of deforestation outcomes over time, and spatial quantification of contemporary forest condition—to tropical Southeast Asia, a global epicentre of biodiversity threatened by deforestation.
Here, we showed how data misrepresentations can degrade the performance of species distribution models, undermining their use for empirial research and conservation science.
Here, we assessed how much savanna had changed in Yunnan over three decades in terms of area and fragmentation, and how much of these changes were due to human intervention versus vegetation transition. We also assessed how climate, landscape accessibility, and fire had altered transition rates.
Our savanna change analysis in Yunnan is featured in the Chinese Academy of Sciences Newsroom.
