 Being a master inventor for me means but supporting others especially young researchers in our lab in the patent development process. Usually there are lots of good ideas around but the step from writing up a disclosure that is sound is not straightforward and I see my task in helping those people to achieve this. I think there is a secret recipe and that is a lot of curiosity and a little bit of ignorance maybe. So the curiosity drives you to explore new fields, to discover new areas and this helps you to find the dots and then you have to connect these dots and to connect these dots that's where maybe you need a little bit of ignorance or to put it in another way you need to be able to detach from the common knowledge. So my first part was about the work we were doing an IBM flash system back in the day working in the flash system controller and trying to improve the performance and reducing the overhead of the cleanup process or garbage collection. This garbage collection is basically the process that your mobile phone goes through after you're overwritten or deleted and erode a new many pictures and you might notice a slowdown and that's typically due to the system trying to clean up the space to make up for new space for you to write to. So we had an idea that the process could be dramatically improved by identifying hot pieces of data that you should let age more before trying to clean them up and a senior researcher part of the team at the time suggested that it was a kind of idea. He walked me through the process and the drafting and reviewing of the parent submission and got granted actually in 2017 and I never thought that a problem that you solve for your day-to-day work could lead up to a parent.
