Research in solar and stellar physics has been tremendously influenced these past decades by the use of seismic techniques that allowed us for the first time to explore the interior of stars. For the Sun, it is possible to go even further with high resolution and high cadence imaging. Thus, since the years 2000 a new field as emerged called “local helioseismology” that gives us the ability to probe in details and in quasi real time the most superficial layers beneath the solar photosphere.The first part of this document reports my activities and contribution in the field of local helioseismology. I show how I actively contributed to the development of the numerical tools that were needed to analyze the new high ...
