I am Bijan Seyednasrollah,

Quantitative environmental scientist, leading the PhenoCam Dataset.

I am broadly interested in understanding complex spatial and temporal processes of the environment using big data and ecoinformatics to tackle major environmental issues.

My projects often consist of






I often use hierarchical modeling, geospatial techniques, remoteley sensed / field data and numerical analyses to solve my problems. I employ combinations of platforms, tools and programming languages to implement/interpret my projects.

Here’s some examples of my recent projects

Ranging from environmental sciences to cutting-edge engineering problems.
