Dr. Nathan Lenssen is an Assistant Teaching Professor in Applied Mathematics and Statistics at Colorado School of Mines and a Project Scientist at the National Center of Atmospheric Research (NCAR). He received his PhD in Earth and Environmental Sciences and MA in Statistics from Columbia University. As an instructor, Nathan develops data science and climate science curricula with a focus on project-based learning and using statistics to better ask and answer questions about the world. His research aims are to better understand variability, predictability, and change of the climate system, while accounting for uncertainty in observational data and biases in dynamical climate models.  He develops statistical and dynamical models as well as the computational methods needed to apply these models to extremely large datasets.
