==Please tell us about yourself==
I am Pengliang Yang, an associate professor from School of Mathematics, Harbin Institute of Technology in China. I started to use Madagascar in 2013 when I was a visiting PhD student at University of Texas at Austin under the supervision of Professor Sergey Fomel. I benefit from the use of Madagascar even in my postdoctoral research in France on multiparameter seismic full waveform inversion. A lot of computer programs I developed when employed as scientist by Electromagnetic Geoservices ASA in Norway has a strong imprint of the coding style I learned from Madagascar. I wish I can pass the skills and the good practices learned to the next generation of the students.

==When did you first hear about Madagascar?==
It was 2010 on an international workshop on in Hainan Island. An invited speaker - Professor Tariq Alkhalifah - mentioned that there exists a useful seismic data processing software called Madagascar, which is open source and shares similar features as Seismic Unix but more advanced in certain aspects.

==What was the most difficult part in learning Madagascar?==
Understanding the data processing workflow built by SConstruct using many programs developed by other developers is more challenging for me. In particular I am unaware of the impact of the parameters used in these programs if they are not properly commented. Indeed, Madagascar is an effort of a number of volunteers with detailed knowledge based on personal logics which can may sometimes be difficult to know.

==From your contributions to Madagascar, which one is your favorite?==
The [https://reproducibility.org/RSF/book/xjtu/ numerical modeling and full waveform inversion codes] I wrote using CUDA GPU programming.

==What advice would you give to those who wish to learn Madagascar or to contribute to it?==
Learn by use; follow the examples that you can understand, adapt them for yourself.
To contribute such that others can benefit from what you did, you should develop codes with good practices - in a way that can be easy to understand, more consistent with math and physics. Sometimes, give a credit to important references that may help the users a lot!
