3nd ACIP Workshop : Cardio Reconstruction MRI


During the morning of Thursday, July 22, the “Cardiac Reconstruction MRI” workshop was held, where our researchers and guests presented their work in the area of ​​cardiac magnetic resonance imaging.

Within the presentations we can highlight the variety of research carried out on this topic, ranging from the theoretical to the experimental.
Among the speakers we have PhD. Evelyn Cueva, post-doctoral researcher of our nucleus and her theoretical work on the physics of cardiac magnetic resonance images and the researcher of our project PhD. René Botnar with the use of cardiac images for the study of cardiovascular diseases.

As for the international guests, we have PhD. Gastao Cruz (King’s College London) and PhD. Thomas Küstner (University Tübingen) who in their presentations combined MRI with the development of inverse problems and machine learning respectively.

The organization of the workshop was in charge of the researchers, PhD. Claudia Prieto (PUC) and PhD. Axel Osses (UCh). With this activity, the ACIP Workshop cycle ends and whose main objective was to create an instance of encounter between the members of the Millennium Nucleus ACIP, researchers and students, as well as national and international guests related to the nucleus’ research areas to promote collaborations and interdisciplinary work.



2nd ACIP Workshop: Adaptive Optics

Precisely on July 5, 2021, the second of the workshops organized by the Millennium Nucleus ACIP took place where the main topic was Adaptive Optics (AO). National and international speakers participated along with ACIP researchers who shared on different aspects of the subject.

Clémentine Béchet, alternate director of ACIP and part of the organization of the workshop, highlights the mix between introductory presentations and other more specific ones, which provided a broad vision of the subject. Andrés Guesalaga, ACIP researcher and co-organizer of the activity, comments on the importance of these meetings, which allow us to know not only what is done at the international level but also the work that is done at the national level in different universities. This allows for better planning of future collaborations.

Both agree that the development of AA in Chile goes hand in hand with the formation of human capital. In this sense, C. Béchet highlights the broad participation of students and postdocs in the workshop. It is an important event in their training, giving them privileged access to interact with the exhibitors. It is important that, thanks to these students and young people, larger work groups can be formed in Chile. This allows participation in more projects already under development and the creation of new ones.

Regarding the next steps in this area within the ACIP, Professor A. Guesalaga tells us that “the Millennium Nucleus ACIP has started a joint work with the Marseille Astronomical Laboratory in France, where our master’s student Francisco Oyarzún will join a mutual PUC-LAM project related to the development of new pyramidal wavefront sensors. We hope that the student will stay in France for 2 months from December of this year ”. For his part, Professor C. Béchet mentioned that the ACIP should participate in the international workshop “Wavefront Sensing in the ELT Era”, organized locally in 2021 by Professor Esteban Vera from the Pontificia Universidad Católica de Valparaíso.

We recall that this activity corresponds to the cycle of 3 workshops focused on the main research areas of the Millennium Nucleus ACIP, where the first of these was in Neurostimulation, which was held on May 20. To end this cycle, the deep learning Heart Imaging Reconstruction Workshop will take place on July 22.

Next Activity

On July 5 and 15, the Adaptive Optics and Cardio MRI workshops will be held, respectively, which are within the ACIP Workshop cycle, belonging to our millennium nucleus.

The objective of these activities is to introduce basic concepts and problems related to the main research topics of the project. On July 5 from 9:00 a.m. to 4:30 p.m. is the adaptive optics turn while on July 15 from 9:00 a.m. to 12:00 p.m. the central theme is cardiac images and MRI where they will meet exhibitors from different nationals and internationally to discuss the advances in these matters and thus stimulate possible collaborations between the various groups with the nucleus. The target audience is researchers and students related to the Millennium Nucleus ACIP, but also possible collaborators and future students.

Adaptive Optics Training

The Millennium Nucleus ACIP together with the Engineering School UC have organized in January 2021 the third Adaptive Optics Training.

More and more instruments at big observatories in Chile are equipped with Adaptive Optics (AO) requiring their staff to understand how an AO system works in order to help produce the best observations out of it. These complex systems are designed to remove the blurring induced by our atmosphere on the ground-based observations. They are just 

indispensable to some kind of astronomical observations. It is thus important that astronomers and engineers working at the observatories get trained to AO.

This AO training, organized together by the Engineering School UC,  the Astro-engineering Center UC (AIUC) and the Millennium Nucleus ACIP, is an introduction to AO designed for engineers and astronomers working at the observatories who might be involved in developments, comissionnings, operations and maintenance of these systems. The training, unique in Chile, allows to train together participants coming from the European Southern Observatory (ESO), the Gemini Observatory, Las Campanas Observatory and ALMA. The training is also an opportunity to create mutual interactions and possible new collaborations between observatories and UC.  

The AO training 2021 (held in January 2021) included the participation of Millennium Nucleus ACIP that has allowed 6 engineering students (from UC and Pontificia Universidad Católica de Valparaíso) to participate in the training. The training consists in about 30 hours of theoretical lectures and 2 sessions of numerical simulations, all given online because of the contingency. Another very important aspect of the training is the hands-on sessions in an optics laboratory at UC during which the participants have the chance to make an AO system work. Because of their key contents for the training, a particular effort has been made to maintain these practical sessions in 2021 despite adapted conditions due to the contingency.

1st ACIP Workshop: Neuroestimulation Modeling


During the morning of May 20, the first workshop of our millennium nucleus, Neurostimulation Modeling, was held. In this instance, it allowed the meeting of our researchers and students around the area of ​​neurostimulation.

The activity was carried out remotely, which allowed the participation of international exhibitors such as Brian Howell (Duke University), Irina Pettersson (Chalmers University of Technologie) and Faouzi Triki (Grenoble Alpes University) and also national Romulo Fuentes (University of Chile).

The day’s welcome was given by our director Eduardo Cerpa, who made known the Millennium Nucleus ACIP, the goals that it has and highlighted the importance of this activity as the first organized by the project to then give way to the exhibitions.

Each of our guests presented his research, all of them related to neuroscience, experimental or theoretical. An important part was the instance for questions and discussion of ideas about what was presented.

This is the first in a series of 3 workshops that focus on the main areas of study of our Millennium Nucleus ACIP.
