Collaboration between the DECIMALS research teams and experienced SRM modelling scientists is a crucial part of the DECIMALS research process. While the DECIMALS scientists are experts in modelling the local impacts of climate change, few have worked on SRM before. Therefore, each team has been paired up with at least one SRM modelling expert and they will work together remotely over the duration of the DECIMALS projects. Eight of the world’s most experienced SRM modellers have volunteered for the research collaborator role, which is unpaid. The research collaboration should be mutually beneficial, with the SRM experts learning about local climate impact modelling, and the DECIMALS scientists learning more about the wrinkles of modelling SRM geoengineering. Further, the regular collaborations between the DECIMALS teams and the pool of collaborators will help connect the teams with the people, debates and opportunities of the wider SRM research community.
The DECIMALS research collaborators are:
Dr Pete Irvine (British)
University College London
Dr Pete Irvine is a Postdoctoral Research Fellow at the Harvard School of Engineering and Applied Sciences working in Prof. David Keith’s group. Dr Irvine conducts research on the climate and broader impacts of solar geoengineering and works to put those findings into perspective with the risks posed by climate change. Dr Irvine was awarded his PhD on the climate response to solar geoengineering in 2012 and worked after this as a post-doc at the Institute for Advanced Sustainability Studies, Potsdam. In recent work, Dr Irvine has worked on novel analyses for evaluating solar geoengineering’s performance at offsetting climate change, and is currently working to evaluate the effects of solar geoengineering on drought and aridity. Beyond this, Dr Irvine has published on the sea-level rise response to solar geoengineering, produced reviews of its climate impacts, and collaborated to produce several interdisciplinary pieces addressing the broader socio-political implications of solar geoengineering.

Dr Doug McMartin (Canadian)
Cornell University & California Institute of Technology
Douglas MacMartin splits his time between Mechanical & Aerospace Engineering at Cornell University and Computing and Mathematical Sciences at the California Institute of Technology. His primary research focus is on solar climate engineering, or geoengineering; working to develop the knowledge base for society to make informed future decisions on these technologies. This includes addressing questions such as estimating climate impacts, using design principles to improve outcomes, how to assess and manage uncertainty in predictions, and attribution. While too little is known today, it is plausible that these ideas could become an additional element of an overall strategy to minimize risks from climate change. In addition to geoengineering, research also includes applying engineering dynamics and feedback analysis to study climate dynamics and variability more broadly, and he is also involved in control design for the Thirty Meter Telescope project. He has authored or co-authored more than 60 journal articles and 70 conference papers, as well as several book chapters on flow control and patents on active noise control. In 2017, he testified in the US Congress at a hearing on geoengineering, and provided briefings to state government and to IPCC lead authors. He received his Bachelors’ degree from the University of Toronto in 1987, and Ph.D. in Aeronautics and Astronautics from MIT in 1992. Prior to joining Caltech in 2000, he led the active control research and development program at United Technologies Research Center.
