Joanna Morgan is a Professor of Geophysics at Imperial College London. She first became involved with Chicxulub when she co-led a seismic experiment across this impact structure in 1996 to map crater size and structure. Subsequently, she has been involved in the onshore drilling of Chicxulub, and running simulations of ejecta travelling around the globe, including its potential to ignite surface fires. She is one of the co-chiefs on IODP/ICDP Expedition 364, drilling the Chicxulub peak ring. Joanna is part of the fullwaveform inversion group at Imperial who have developed a high-resolution imaging technique for the petroleum industry to improve images across reservoirs. Joanna has used this novel technology to obtain fine-scale images of the peak ring at Chicxulub, mid-ocean ridges and subduction zones, and is currently working on imaging magma storage beneath the Santorini volcano.
