Hi there! I’m Dan, and I’m a climate modeler. My main area of expertise is the behavior of stratospheric aerosols and how they interact with atmospheric chemistry and with the surface climate. I am currently a Postdoctoral Researcher at Cornell University, Sibley School of Mechanical and Aerospace Engineering, working with prof. Douglas MacMartin on our newly funded Geoengineering Assessment across Uncertainty, Scenarios, and Strategies GAUSS project!
My research is currently focused on studying Sulfate Geoengineering, a form of climate engineering that aims to reduce surface temperatures by means of injecting sulfate precursors in the stratosphere in order to reflect a small part of the incoming solar radiation and thus reduce global temperatures. I’m also interested in other climate engineering methods (Marine Cloud Brightening, Cirrus Thinning) and I continue studying the effect of past and present volcanic eruptions on climate.
I work towards a deeper understanding of how different deployment strategies would impact the surface climate differently, and how we can minimise these impacts.
To do so, my research spans various topics:
- The interactions between aerosols and atmospheric dynamics (1), (2), (3) and chemistry (4) (5)
- The physical mechanisms and sources of uncertainties (6) in aerosols microphysics and aerosol-clouds interaction (7) in climate models
- The space of possible strategies (8) for controlling various climate metrics through injections at different locations and times of year (9)
- The impacts on ecosystems (10) and surface climate (11) (12)
- The international governance aspect of climate engineering
