I am currently @ Stockholm Resilience Center, Stockholm University, Kräftriket 2B, SE-10691 Stockholm, Sweden
I am a Postdoctoral Scientist at Stockholm Resilience Center in Stockholm University, and affiliated to the Planetary Boundaries research group. I am also an Earth-Doc at the Earth League international research alliance. Since the beginning of 2016, I have been involving myself in the activities of several international research networks and projects concerning global dynamics, e.g. TWI 2050 and AIMES. I serve as a member of the Society of Environmental Toxicology and Chemistry (SETAC) and European Geosciences Union (EGU), and am a U.S. Department of State Alumni. I am also an enlisted urban planner of the capital development authority (RAJUK) of Bangladesh.
My primary research focuses on the patterns of Anthropocene. This involves a deep understanding of the variability of several anthropogenic processes, e.g. climate and land use dynamics, degradation of land and water resources, across spatiotemporal scales and underpinning their human and ecological impacts. My interdisciplinary research also involves cross-scale socio-cultural, socio-economic and social-ecological dynamics, and their interactions with earth system dynamics.
I apply a data-driven empirical approach and spatiotemporally explicit statistical modelling in my research. I possess theoretical and hands-on expertise in Geographic Information Science and Systems (GIS) and Spatiotemporal Statistics (SS). Development of novel GIS and SS tools, and advancement of existing GIS and SS tools through command line environment (C++, Shell) and (co)interfacing open source software packages, i.e. R and GRASS GIS, are integral parts of my research. Besides big data management and pattern identifications, my research concerns data scarcity and filling data-gaps using novel algorithms to reduce uncertainty of spatiotemporal variability modelling.
I teach and supervise courses and theses concerning cross-scale climate, land use, environmental and social dynamics. I give tutorials on how to employ command line environment and open source software packages for GIS and SS analyses.
In my pastime, I enjoy photography, play guitar, sing and travel. This website gives you an overview of my research, supervision and teaching, lists my publications and gives access to them on request. Moreover, it hosts an interactive blog “Spatiotempotal@Avit”, which is dedicated to publish insights, theories, methods, tools and code snippets for spatiotemporal analyses. It also introduces you to the photographs I have captured and places I have traveled so far.
The word cloud is based on the highlights from my publications (see publication section for details). Identification of the highlights and creation of the word cloud was performed using the R package wordcloud.
Software and Tools
SSTP: Spatially Shifted Temporal Points. This is an alternative method for pooled within-time series variogram computation and developed on the open source software R.
ATRIC: automated Accumulation Threshold selection and RIparian Corridor delineation. This tool enables automated stream network extraction and upstream riparian corridor and catchment extraction from digital elevation models at large scales.

- Global Ecology and Biogeography
- International Journal of Climatology
- Earth Science Informatics
- Geomatics, Natural Hazards and Risk
- Journal of Environmental Informatics
- Water Science and Technology: Water Supply
- Journal of Health and Pollution
