Controles tectónicos y climáticos en la evolución paleoambiental de la cuenca baja del Río Mendoza durante el Pleistoceno tardío-Holoceno.
La evolución geomorfológica y la reconstrucción paleoambiental del antiguo Río Mendoza no han sido analizadas en forma integral ni espacial ni temporalmente. Las principales reconstrucciones asociadas a este recurso fundamental del Oasis Norte de Mendoza se han abordado desde enfoques históricos y arqueológicos que difícilmente comprenden más allá de los 2.000 AD. Posiblemente este hecho ha sesgado la interpretación de las posibles causas climáticas asociadas a la dinámica ambiental de este segmento de los Andes. Sin embargo, el hecho indiscutido de ubicación de la zona de estudio en el frente orogénico activo de los Andes, asociada a una intensa actividad sísmica, permite sospechar que la tectónica pudo jugar un rol fundamental en la evolución geomorfológica de la cuenca baja del rio Mendoza. Así, la historia ambiental de Mendoza norte está asociada a la evolución y dinámica de la cuenca baja del Rio Mendoza donde los procesos geomorfológicos, climáticos y culturales están íntimamente relacionados. La comprensión de los procesos geomorfológicos es fundamental para las investigaciones arqueológicas, así como para otras disciplinas como la hidrogeología, los riesgos ambientales, e incluso la salud pública. Esta investigación es parte integral de estudios previos realizados junto a geólogos, arqueólogos, hidrogeólogos, ingenieros civiles, paleoclimatólogos y palinólogos. PICT-2019-3426 (2021-2024)

Quantitative temperature reconstruction in the Patagonian Andes (49°S) since the mid-Holocene
The scarce studies about the impact of current climatic change on high Andean modern environments of South America point out a sustained loss of the coolest areas and an upslope displacement of the vegetation belts associated with a loss of diversity. 
Tree ring studies carried out in the upper tree line in the southern Andes revealed a continuos increase on the trees annual growth since the late XX century associated to a temperature increase. As most of the paleoclimate reconstructions from southern Patagonia indicate precipitation changes, there is no idea of temperature natural variability in the "recent" past so as to figure if the historical increasing trend is part of it or an anthropogenic issue.
So, the present project aims to quantitatively reconstruct the temperature  in the southern Andes (49°S) since the mid-Holocene. In order to do this, the past dynamic of the high Andean steppe - Nothofagus forest ecotone will be assessed based on pollen records of high Andean lakes and a modern polen-climate calibration.

Climate change and landslides occurrence in the subtropical Andes since the Late Pleistocene

The present project integrates evidences of past climate and environmental changes in the subtropical Andes together with landslides occurrence and dynamics aided by modern climate research to disentangle the associated mechanisms at the synoptic scale and the climate trends at decadal scale.

The evidence from the three research lines results in (1) a broad knowledge of the palaeoclimatic dynamics of the subtropical Andes regarding winter precipitation and secondarily, summer precipitation; (2) a detailed study of landslides occurrence, frequency and timing and the associated climatic conditions from the Late Pleistocene to historical and recent times and; (3) an integral understanding of modern climate trends from the synoptic to the decadal scale in the subtropical Andes that  shed light to the links between climate and landslides occurrence. The integration of these results are key to foster future events under the current climatic change scenario and for the assessment of the related hazard and risk, which are essential to reduce social and economic impacts on vulnerable communities.

Past climatic and environmental dynamics of the southern Atacama Desert (24°-27°S) since the Late Glacial
The present project aims to trace the palaeoenvironmental and palaeoclimatic dynamics at southern Atacama Desert (24°-27°S) since the Late Glacial through the fossil rodent midden pollen record analysis. The project will be focused on tracing (1) the interaction of summer/winter rainfalls through time and space by analyzing changes in the midden pollen assemblages at different altitude and latitude complementarily supported by 18O isotopes in fossil plant macro-remains cellulose and (2) the effects of climatic changes occurred since Late Glacial on the vegetation communities at a biogegraphically hinge area as the Southern Atacama Desert.

Palaeoclimatic dynamics of western Central Andes (18°-25°S) since the Pleistocene-Holocene transition
The present project traces palaeoclimate dynamics at western Central Andes (North and Central Atacama Desert; 18-25°S) since the Pleistocene-Holocene transition by quantifying how past climatic changes affected past distribution of plants. This is carried out through the analysis of fossil pollen preserved in rodent middens with a broad spatial distribution across western Central Andes and temporal coverage. Analyzing the same proxy (pollen) from the same palaeoclimatic archive (rodent middens) through time across western Central Andes guaranty to capture the past climate variability at the same spatial and temporal scales. Thus, it will be possible to test whether the western Central Andes climate varied in phase since the Pleistocene-Holocene transition or different modes prevailed through time.

Arqueología del norte de Neuquén: geografía humana, tendencias temporales y procesos demográficos
The present project aims to trace past human societies dynamics in Neuquén province (Argentina) from a multidisciplinary approach including ecological, archaeological and palaeoecological research.  Palaeoecological research is being performed through a multiproxy approach (pollen, plant macro-remains and palaeoparasites) on fossil roddent middens encompassing the last 11ka.
