    My interests lie in moral and political philosophy and practical rationality, as well as intersecting areas in economics and politics. I am especially interested in issues of distributive justice, including ones arising across states and generations. My current work examines how egalitarian distributive principles should accommodate concerns with risk and with personal and collective choice and responsibility. It also explores how such principles should guide the design of social institutions that shape the prospects of children, parents, the elderly, and future generations.

    I work on quantum information, especially quantum Shannon theory, which aims at incorporating information-theoretic ideas into physics. The Shannon theoretic approach has succeeded in quantifying entanglement as a resource in information processing task, and likewise for other properties of quantum systems such as channel and storage capacities of quantum systems. One of my favourite topics is the interplay between classical and quantum information, evident in the intricate structure of local operations in composite quantum systems (LOCC), such as data hiding or "information locking". I also work on additivity and non-additivity of quantum channel capacities, quantum data compression, and zero-error quantum communication. Further quantum information interests include statistical mechanics, entropy characterization and entanglement measures. But at heart I am a mathematician and will still get fascinated by classic problems: existence of Hadamard matrices, incompleteness, etc.

    The keyword is the behaviour of fluids at nano-scale. I study the transfers of ions and water molecules through nano-metric (tens of nanometers) barrier layers of composite nanofiltration membranes. They are used, for example, to remove hardness from seawater. Another example is the transfer of ions and water through nano-porous track-etched membranes having identical cylindrical pores. I also study processes of current-induced concentration polarization of nano-/micro-interfaces where the concentration polarization is strongly-coupled to electroosmosis. Recently, I discovered that a layered structure consisting of a micro-perforated ion-exchange membrane and a nanoporous layer can have very interesting properties useful for AC electroosmotic pumps. Another topic is experimental and theoretical studies of ion transfer across polyelectrolyte multilayers where we have recently discovered very high (>1000) selectivities in the electrically-driven transfer of ions of different charge magnitudes. I'm also interested in the emerging membrane process of forward osmosis trying to understand where it can be better than the more traditional pressure-driven processes (e.g., reverse osmosis).

    Zabala's research concentrates in three areas each of which have generated several authored and edited books: ontology, political philosophy, and aesthetics. All these three areas are studied following the hermeneutic principle according to which truth is not an objective goal that philosophy must submit to, but rather the effect of the conflict of interpretations. Following the work of Martin Heidegger, Hans-Georg Gadamer, and Gianni Vattimo Zabala has emphasized the ontological nature of hermeneutics in order to demonstrate the danger of truth impositions for religious and political emancipation. His next books and articles will be on political ontology and aesthetics.

    The Middle-to-Upper Paleolithic transition in Europe has been the focus of my research for the last 15 years. This research interest has led to fieldwork at different sites, namely: (a) the Lagar Velho rock-shelter (Portugal) and its burial of an early modern human child with diagnostic Neandertal features (skeletal evidence of interbreeding at the time of Neandertal/modern contact in Europe); (b) the Gruta da Oliveira (Almonda karstic system, Portugal), where ongoing work has already exposed 11 m of deposits spanning the ~35-70 ka cal BP interval; (c) the Pestera cu Oase (Romania), site of Europe's oldest modern humans; (d) Cueva Antón (Murcia, Spain), with Mousterian painted and perforated marine shell ornaments that proved the behavioral modernity of the last Neandertals. My current research focuses on documenting the late persistence of the Neandertals in Iberian regions located to the south of the Ebro drainage and its ecological and cultural underpinnings.

    She is unraveling the impacts of global environmental changes on marine ecosystems and biogeochemistry at various time scales and complexity through multidisciplinary investigation of key marine calcifying groups at the base of the food web. Her work on the oceans in a high CO2 world is focusing on the links between CO2 dynamics, climate change and marine organisms in areas such as the Mediterranean Sea and the Southern Ocean, integrating both modern and past global changes. These changes disturb the capacity of marine systems to provide ecosystem services, which affect economic activities and human welfare. Evolving interests have led to new research on microplastics in the Mediterranean island coastlines, and invited memberships, such as the UN-GESAMP, WG 40, Sources, fate and effects of microplastics, advisory board member of the IAEA project OA-ICC, Monaco and a SOLAS/IMBER carbon group member, WG3 ocean acidification.
