Research and Teaching Assistant
As a Swiss-Colombian native, I lived in the USA where I received a Bachelor of Science degree in Psychology at the University of Texas at Austin. Currently, I am a second-year masters student at the University of Geneva. Under the co-supervision of Prof. Evie Vergauwe and Dr. Lea Bartsch, from the University of Zurich, my masters thesis is focused on disentangling the neural mechanisms of working memory, specifically that of attentional refreshing, by studying the brain’s electrical activity with EEG. As an RA in the lab, I am assisting with different projects also focused on working memory in adults: uncovering cognitive strategies such as verbal rehearsal with artificial intelligence (Dr. Kim Uittenhove), decoding verbal memory using EEG (Prof. Vergauwe and Dr. Bartsch), and better understanding the vulnerability of working memory (Dr. Naomi Langerock). Along with other lab members, I also take part in the Swiss Reproducibility Network Geneva Local Node’s activities, such as the ReproducibiliTea Journal Club, which promotes open and reproducible research practices in an interdisciplinary context.
Hitting refresh (master’s research project)
Refreshing is known to be a spontaneous mechanism for reactivating and maintaining information in working memory, when sufficient attention is available. Although it is well-known in the behavioral literature, the existence of refreshing and its characteristic properties are still debated today. Thus, in my master’s thesis, we are seeking to identify the neural underpinnings of refreshing in adults by decoding it using multivariate pattern analysis on electroencephalographic (EEG) data. By assessing WM representations and the brain’s electrical activity together, we may be able to better explain the nature of spontaneously reactivated working memory representations.

To be or not to be relevant: the long-term consequences of prioritization of working memory
There are many ways in which we can guide our attention in order to focus on the tasks at hand. Working memory allows us to flexibly prioritize and maintain certain memories over others. Moreover, priority-based allocation of attentional resources has shown robust effects in working memory. The impact of these effects in long-term memory, however, are much less clear. In this study, we compared cue-based vs. reward-based prioritization in working memory, and assessed their differential impact in long-term memory.
