Colin Raymond
I am currently an Assistant Research Scientist at the University of California, Los Angeles, with a secondary affiliation at the NASA Jet Propulsion Laboratory. My research centers on better understanding how weather systems interact with geographical features to produce climate extremes (especially heat, humidity, and precipitation) at local and regional scales. Sequences and combinations of variables which result in 'compounded' or 'correlated' societal risks figure prominently. My projects draw from a variety of observational and model-based data sources. My interests also include producing and communicating climate information such that it is most useful for decision-making, through contributions to impacts assessments, stakeholder conversations, and educational and outreach activities.

Professional Service and Activities
-Co-lead of the Risk KAN Compound Events working group (~250 members); have been organizing regular webinars and other networking activities since April 2020.
-Primary organizer of the "Workshop on Correlated Extremes", a ~175-person event held at Columbia University in May 2019. Our goal was to weave together multiple physical- and social-science perspectives on correlated climate extremes -- an emerging topic spanning meteorology, climatology, natural hazards, and policy/finance -- and to help build research networks and shape research directions in this area. More information is available at our website. Recordings of all talks are available on Youtube.
-Other conference organization and chairing:
Como Training School on Compound Events 2022
"Climate change as a systemic risk" session at EGU 2022
Workshop on Compound Weather and Climate Events, January 2021
"Correlated/compounding climate extremes" sessions at AGU Fall Meetings, 2019-22
"Extreme heat events: processes, impacts, and adaptation" session at EGU 2019
