Deepa Mele Veedu joined NTU as an ASE student in 2014 and started her first study on the Parkfield tremors with Sylvain Barbot, in which she discovered slow and fast ruptures on the same patch. After publishing that work in 2016, she wanted to produce slow-fast ruptures in a laboratory setup. With that in mind, she visited the National Institute of Geophysics & Volcanology, Italy in 2017 using the Stephen Riady fund. In Italy, she collaborated with Carolina Giorgetti, Marco Scuderi, and Cristiano Collettini. On a beautiful day, they witnessed laboratory events slipping slow and fast, one after another, in granular quartz material. Hence, they validated the numerical results. To test if another laboratory setting can reproduce the same slow-fast phenomenon, Deepa has extended her collaborations with Chris Marone, Penn State University, in 2018 using the second-time Stephen Riady funding. With the team at Penn State University, she reproduced the same slip behaviour in quartz material with six different grain sizes, once again showing that the results are robust, and it can be applied to a range of slip observations from natural faults.
