Who am I? Where do I come from? And what am I doing?

Hey. Everyone, welcome to my blog.

I will introduce u myself and give you a quick view of my PhD topic.

Who am I? Where do I come from?

My name is Xin WANG. It is a typical Chinese name, and yes. I am from China.
For the first year of my undergraduate, I studied underwater acoustics in China. Then I moved to France.
I studied acoustics as an undergraduate in Université du Maine. Then, for my master, I changed my major to electronics and continued my study in Pierre and Marie Curie University.  
Now I am working in a European project named  'INFRASTAR' and doing my PhD thesis in BAM (Bundesanstalt für Materialforschung und -prüfung), Berlin.

What am I doing?

My PhD topic is 'Advanced ultrasonic instrumentation for interferometric monitoring'. So what I do is to monitor the concrete using ultrasonic sensors. But why we do this? Concrete is the single most widely used material in the world especially for the civil infrastructures. The neglecting and excessive use of the existing public infrastructures has led to the accelerated deterioration of bridges, buildings, transportation systems, etc. The performance of structure is gradually degraded or be damaged. In the material of an engineering structure like concrete or steel, fatigue damage could not be seen and failure occurs suddenly and without any early warning. Therefore, it is necessary to monitor the health of concrete including the damage, fatigue, load distribution, etc. The most common monitoring method is ultrasonic pulse velocity test, because of its limitation; a new method ‘Coda wave interferometry’ is developed.

As I am in this European project, I need to cooperate with other ESRs (Early stage researchers). Especially with the ESRs from Work Package 1 (Of course, I am also from WP1). We share datas and analyse together. For example, I collect the ultrasonic data and Antoine ESR2 (click to know more about Antoine) he collects fibre optics data.

Well that's a quick introduction about me and my works.

And I really appreciate this opportunity to work with all the other ESRs and all the supervisors.

And luckily,  we have a very 'funny' project manager Hakim who helps us a lot and makes our work more relax and interesting.
