I am an enthusiastic academic researcher, project leader, and research instructor. My overall research interests and skills include experimental, analytical, and field-based geology, petrology, volcanology, and mechanics of multiphase magmas and volatiles in the Earth’s interior. I have fieldwork experience in a broad range of environments, ranging from sedimentary to metamorphic, from plutonic to volcanic. I am skilful in high-pressure and high-temperature experimentation and multiple micro-analytical techniques, including tomographic microscopy, to address chemical and physical aspects of:

1) Multiphase magma rheology

2) Fluid migration in magmas

3) Magma degassing, transport, unrest, and eruption

4) Magma differentiation and evolution of the Earth's lithosphere.

I apply a creative approach transcending traditional disciplinary boundaries in my research and in my lectures.

Currently, I am building up my new experimental Petrology and Volcanology Laboratory MAGMA MIA... Coming soon!

Research Interests:
  • Multiphase Magma Rheology in Earth’s Crust and Volcanic Systems

Magma FlowDuring my PhD research studies at ETH-Zurich (Switzerland), I investigated the rheology of crystal- and bubble-bearing magmas using high-pressure and high-temperature experimentation. I quantified the simultaneous influence of gas bubbles and crystals on the rheology of multiphase magmas. The major results show that: i) the limited presence of exsolved gas diminishes viscosity of crystal-rich mushes (> 50 vol%) by four order of magnitude, with a consequent increase of their rheological mobility during transport and emplacement in the Earth’s crust, ii) the gas extraction during deformation of crystal-poor systems (< 50 vol%) favours an increase of viscosity with increasing deformation rate, which ultimately leads to magma fragmentation. This research represents the first milestone of my academic career allowing me to be able of combining both chemical and physical parameters to address the physics of magma transport, emplacement, and eruption.

  • Fluid Transfer during Magma Mixing and Rock-Rock Interaction

Magma Mixing

During my first postdoc fellowship for which I received independent funds, I explored the chemical and physical conditions of volatile transfer during interaction of magmas of different composition and crystallinity. The transfer of volatiles is dictated by gradients of volatile concentrations between two interacting systems and, during volatile migration by diffusion from one magma to another, the liquidus temperature swings as response of volatile depletion, inducing simultaneous crystallisation in the system releasing volatiles, and partial melting of the system affected by volatile addition. The most outstanding result of this process named as “chemical quenching” is the experimental replication of unidirectional solidification textures or comb layering, commonly found in plutonic rocks and ore deposits that fascinated the scientific community for several decades. Following this research line and similar experimental design, I also explored how fluids (water and melt) influence chemical and textural changes of pervaded rocks during transport and how they chemically react with surrounding minerals. Fluid transfer can be effective in causing textural changes without changing the bulk chemistry of the pervaded rock. Diffusion of water and migration of limited amount of melt can be chemically stealthy and, thus, remain cryptic when studying natural rocks.

  • Synchrotron-based, In-Situ & Time-Resolved / -Elapsed Vesiculation in Magmas

Vesiculation

Since my PhD studies, I have adopted experimental approach at the forefront, which includes in-situ, real-time observation of magma vesiculation at high temperature at the synchrotron source. TI also contributed to the technological design, development, construction of high-temperature furnaces for these experiments. This experimental approach allows performing experiments that capture the kinetics of vesiculation of magmas “on-air” and allows overcoming the typical challenges of reconstructing dynamic processes based on post-experiment analyses alone. This experience gave me the opportunity to design new pioneering investigations and work side by side with technicians, external contractors, and scientists from research fields other than Earth Sciences.

  • Melt Percolation Processes in Crustal Rocks

Gas Filter Pressing

Since my postdoctoral stage, I investigated the chemical and physical conditions at which residual melts from partially crystallised magmas can infiltrate within rocks, ascend through the crust, and become eruptible at Earth’s surface. In particular, I investigated the role of volatiles in driving melt extraction from crystal-rich magmas or mushes. For instance, I experimentally determined the optimal conditions of melt extraction driven by gas filter pressing during magma cooling and by water diffusion during magma mixing. The experimental observations have offered precious insights into the generation of crystal-poor melts and their efficiency to be mobilised and become eruptible at active volcanoes.

  • Volcanic Arc Systems

KanagaDifferentiation and transport of mantle-derived, hydrous, basaltic magmas is a fundamental process that produces the evolved intermediate to silica-rich magmas that form the Earth’s crust. During my “overseas” postdoctoral period, I focused my research on the the influence of water and oxygen fugacity on the fractional crystallization or liquid line of descent of hydrous (i.e., water-bearing) basalts in order to evaluate the switch between calc-alkaline (“Fe-poor”) and tholeiitic (“Fe-rich”) magmatic trends at shallow crustal levels. The experimental effort was accompanied by a unique field mission in the Western Aleutians in September 2015. During this incredible geological adventure, I sampled many kilos of volcanic rocks and helped with installing novel equipment for seismic stations to monitor the nine volcanoes I explored between Buldir (westermost island) and Kanaga (eastermost island).

  • Pluton Emplacement and Construction in the Earth’s Lower Crust

MastalloneMultidiplinary investigation using fieldwork, analysis of natural rocks, and rock physics modelling help determine magma emplacement mechanism in the lower crust. Specifically, I conducted fieldwork in the Ivrea-Verbano Zone (Italy) to study the Permian Mafic Complex and unravel the physical and chemical architecture and construction of a large mafic body by repetitive emplacement of sills. Currently, I am applying 3D rock fabric analysis using micro-tomography data with TomoFab open-source MATLAB package to determine shape preferred orientation (SPO) of rock-forming elements, including minerals, aggregates, and pores. This research is part of the large-scale research initiative DIVE of ICDP, for which I am one of the six leading PIs: https://www.icdp-online.org/projects/world/europe/ivrea-italy/details/
