Sarah Armstrong

RPS

Professional/research interests:
I am an Assistant Acoustic Consultant at a large consultancy firm. My work largely involves carrying out surveys and delivering reports for clients in support of planning applications, or in response to noise complaints.

What would you like UKAN to do for you?
I'm new to the field, and would like to broaden my knowledge of acoustics and eventually pursue a specialism in an area of interest. I would also like to engage and participate with the wider acoustics community to learn more about my field, and its future direction.

How would you like to contribute to UKAN?
I can offer insight into acoustic consultancy, and may submit research and observations noted over the course of work.

PHD Emmanuel ATTAL

Professional/research interests:
My researches are focused on acoustics in air media (acoustic wave in non homogeneous materials), signal processing and in biomedical acoustics (acoustophoresis)

What would you like UKAN to do for you?
I would like to find a professional opportunity (postdoctoral position), either in acoustic applied to air media or in biomedical acoustics in order to discover new topics and to work with new collaborators

How would you like to contribute to UKAN?
I would like to bring my knowledge in each topics where i have acquired an expertise. I wish to contribute to the development of new acoustic experimental setup.
