30-04-2024 Caracterización de eventos de oleaje extremo y su influencia en lagunas costeras – analisis de serie de tiempo
Este proyecto tiene como objetivo investigar los efectos de eventos de olas extremas en estuarios, lagunas y humedales en Chile central. Estos eventos, caracterizados por marejadas durante las mareas altas de sizigia, aumentan el volumen de agua y alteran la morfología de las lagunas costeras. Como resultado, las olas oceánicas pasan por encima de las barras de arena de las playas, introduciendo agua salada y sedimentos en las lagunas, lo que provoca diversos impactos físicos e hidrodinámicos, como inundaciones costeras y cambios en la estratificación de la salinidad y los niveles de oxígeno disuelto. El proyecto se centrará en el análisis de series de tiempo de datos (nivel del agua, marea, oleaje) de sitios en Chile Central (Cahuil, Pichicuy, Ligua-Petorca). Los resultados esperados incluyen determinar las condiciones en las que se producen estos eventos y analizar sus caudales episódicos.Es probable que durante el proyecto haya oportunidades para ayudar en trabajo en terreno.

30-04-2024 Characterizing extreme wave events and their influence on central Chilean estuaries, lagoons, and wetlands - time series analysis
This undergraduate research projects will study the influence of extreme wave events in coastal estuaries, lagoons, and wetlands. Large waves (marejadas) that occur during spring high tides are observed to increase the water volume and change the morphology of coastal lagoons. During these events, oceanic waves pass over the beach sandbar and bring salt water and sediment into the lagoons. Physical and hydrodynamic impacts include coastal flooding, changes to salinity stratification and dissolved oxygen. Quantifying conditions and impact of these events will be carried out using time series analysis using data (e.g., estuarine water level, tide, wave) from sites in Central Chile (Cahuil, Pichicuy, Ligua-Petorca) and California (Pescadero). Expected outcomes include: a parameterization of when these events occur, and an analysis of the episodic flow rates. There will likely be opportunities to assist with field data collection during in the Central Chilean sites.

07-06-2021 Study about the electrophysiological decoding of cognitive processes
This study will analyze the rhythmic activity of the electrophysiological signals produced by the brain, which is one of the most approachable manifestations of the brain activity underlying cognitive functions. One of the most important tasks in this approach is to select the relevant information and filter the environmental and internal noise. Therefore, an algorithm must be implemented that allows the raw data to be extracted and transformed into a signal that corresponds to the cognitive processes that are being evaluated. In this course, the student must implement algorithms for classification, decoding and description of the oscillatory activity of the EEG signal in humans, during the development of tasks that mainly assess memory and attention. For this we will use standard computational signal analysis tools.
