Dr. Francis Collins, Director of the NIH, wrote a blog post summarizing our recent Science paper and earlier work on RSV. Link here: https://directorsblog.nih.gov/2020/06/02/will-warm-weather-slow-spread-of-novel-coronavirus/
I have a new paper out in Climatic Change, co-authored with the brilliant Ayesha Mahmud and Jessica Metcalf. The first figure in the paper is this striking correlation between state-level estimates of varicella R0 (a measure of disease transmission potential) and average humidity for those states. In the paper we do a lot of work to move from this high-level observed correlation, to a richer understanding of the climate drivers of varicella, disentangling other factors that might bias this observed relationship. In the process we attempt to synthesize mechanistic approaches that capture the dynamics of these types of diseases very well, with statistical approaches required to tease out climate effects from observational data records. Nevertheless, this macro-level correlation still stands to motivate our intuition: our main result (after much more modeling work) supports this observed relationship.
The cool thing about our method is we end up being able to generate future simulations that capture the known dynamics of the disease and incorporate climate dependence. When we force these simulations with projections for changing environmental conditions, we find that climate change could cause a seasonal shift in cases from winter to summer months. This finding, that climate change may interact with the dynamics of airborne diseases, may have implications for public health provision. It is something we hope to investigate further in future research!

I recently defended my PhD. A big thanks to my committee: Michael Oppenheimer (my adviser), Tom Vogl, Solomon Hsiang (UC Berkeley) and Bryan Grenfell.
I recently convened a session at the American Geophysical Union Annual Meeting 2017, on the Climate Drivers of Infectious Disease: Past, Present and Future. The session is now available to view on Youtube! Check out this link to hear all the talks.
