Research Topics & Areas of Expertise
Geographic Information Systems (GIS), Remote Sensing, Spatial Modeling, and Data Mining for urban and environmental analysis and planning. Some of my recent research has focused on mapping urban land cover (green space, impervious surfaces, etc.) and monitoring forest health using fine resolution satellite imagery.

In Remote Sensing
In object-based image analysis (OBIA), the appropriate parametrization of segmentation algorithms is crucial for obtaining satisfactory image classification results. One of the ways this can be done is by unsupervised segmentation parameter optimization (USPO). A popular USPO method does this through the optimization of a “global score” (GS), which...

The advent of very high resolution (VHR) satellite imagery and the development of Geographic Object-Based Image Analysis (GEOBIA) have led to many new opportunities for fine-scale land cover mapping, especially in urban areas. Image segmentation is an important step in the GEOBIA framework, so great time/effort is often spent to ensure that...

Commissioned Report
Bangladesh, being one of the most vulnerable countries to natural disasters and global climate change, faces different individual and catastrophic shocks creating severe impact on the lives and livelihoods of the marginal segment of the population. In the context of climate change, action research within an experimental design is needed to identify...

In Satellite Earth Observations and Their Impact on Society and Policy
REDD+, a policy framework through which developing countries can receive incentives for reducing their greenhouse gas emissions in the forest sector, heavily relies upon Earth observation (EO) data for policy implementation. Thus the quality and quantity of the EO data used can have an impact on the effectiveness of REDD+. In this chapter, we: (1)...
Conference Paper
Proceedings of the 16th World Lake Conference
Land cover (LC) has a significant impact on rainfall-runoff dynamics of a watershed, so LC maps are often incorporated into hydrological models to simulate how changes in climate or land management will affect water quantity/water quality within the watershed. The accuracy of a LC map can thus affect the accuracy of hydrological modelling results...

Literature suggests a significant potential for synergies among climate change adaptation and mitigation (CCA & M) policies, especially in urban areas. However, the understanding of how best to integrate CCA &M is limited despite the fact that there is an increasing interest, particularly in Southeast Asian countries, in achieving the integration...
