Alice Delmer: From Waves to Localisation

Alice Delmer

Alice Delmer is a PhD student in signal processing at the laboratory for systems and applications for information and electrical energy technologies (SATIE - Université Paris-Saclay, ENS Paris-Saclay, CNRS). Her thesis studies "parsimonious goniometry of radio sources: models, algorithms and robust implementations".

Tell us about your thesis subject.

I work in the field of signal processing, a combination of applied mathematics and applied physics. My specific interest is in signals received by antennas including mobile phone and radio signals.

I try to understand where they come from and locate the transmitters. Then I model the signal with mathematical equations. To find the solution, I search for algorithms and criteria that can be optimised.

What is your academic background?

I studied electrical and electronic engineering at ENS Paris Saclay and graduated with a Master’s in signal processing and imaging. The programme included a one-year research internship abroad that I loved. It gave me time to get my teeth into my subject and to pursue my chosen direction thoroughly. Continuing with a thesis was the next logical step. The particularity of my thesis is that it involves a partnership between a company and a research laboratory (CIFRE thesis). I work at Thales part time to help them find solutions to their problems. I like the fact that my subject has potential for concrete industrial application. Working with people with different perspectives also helps me to develop an approach that is both academic and industrial.

Why did you decide to participate in the My Thesis in 180 Seconds competition?

It is very complicated to explain a thesis subject to non-specialists. Reflecting about how to present it in three minutes was an interesting exercise. And it is extremely motivating to present in public and manage your stress. And learn how to develop an explanation and deliver it in context.

What do you intend to do when you finish your thesis?

I would like to continue with research, but in the business sector. I want to pursue concrete applications and not be detached from real life. Perhaps at Thales.
