    Living cells are internally highly organized, yet also very dynamic. How is dynamic order generated? The cytoskeleton plays a critical role in this process by forming an active filament network that provides a mechanically stable coordinate system for the internal organization of cells. The Surrey lab studies the properties of the microtubule cytoskeleton with a particular interest in its ability to organize itself into different networks in different cell types or at different times of a cell's life cycle. The Surrey lab has pioneered several biochemical in vitro reconstitution approaches in which minimal cytoskeletal subsystems can be generated from purified components. Observing the behaviour of these reconstituted systems by advanced fluorescence microscopy provides insight into the molecular mechanisms underlying cytoskeleton dynamics and function. Our goal is to uncover the design principles governing active biological network organization which is essential for cell function.

    He works in the field of theoretical (bio)inorganic and supramolecular chemistry, and works on transition-metal complexes, metalloproteins, and DNA. The development of computational tools for these studies is an important ingredient, to which he has contributed largely both with his own software (QUILD, DRF90) as in contributions in general purpose software (ADF, NWCHEM). One of the main areas where these tools are applied is in the field of transition-metal chemistry, the spin states involved, and the effect this has on reactivity, selectivity, chemical bonding and spectroscopy. For this he developed spin-state consistent density functional (SSB-D, S12g).  His received the Young Scientist Excellence Award (2005), the MGMS Silver Jubilee Prize (2012), and a special award by the Serbian Chemical Society for his continuous support for advancing chemical sciences in Serbia (2017).

    The research work carried out by Albert is in advanced materials for energy applications. In particular, he has been developing innovative concepts for improving the performance of different solid state energy devices such as Solid Oxide Fuel and Electrolysis Cells (SOFC/SOEC), ThermoElectric Generators (TEGs) or Li-ion batteries for energy storage and portable power applications. In the last years, Albert has been specifically developing new concepts for the unexplored field of Nanoionics and Iontronics. They are called to drive a new revolution similarly to Nanoelectronics, underlining the relevance of size effects and interfaces on mass transfer, transport and storage. Albert's group is pioneer in implementing interface-dominated nanomaterials in devices for radically new applications. In this direction, he was awarded with an ERC CoG to implement disruptive Nanoionics concepts in Si-integrated micro-SOFC technology and two FET Proactive projects on new microenergy technologies.

    My main research areas are Fourier Analysis and Approximation Theory. Particularly, I study the relationship between "smoothness" of a function and the possibility to approximate or to represent this function by a sum of "simple" functions. The case when "simple" functions have wave structure is of special interest.

    My studies are raising the question about the geographical, linguistic, religious, cultural and mental borders of the multi-layered legacy in the centres and peripheries of the Medieval Worlds. First, I have analyzed the Europe-wide intellectual attraction and radiance of the Parisian abbey of Saint-Victor in the mirror of its exegetical and theological production, focusing on the German, Anglo-Saxon, French, Italian and Hispanic areas. Then, I have broadened my panorama to reconstruct European religious and intellectual identities by conducting extensive research on texts of Christian-Muslim encounters and perceptions in Europe. On this basis, I have been able to pursue studies on early Christian polemics against Islam, on the linguistic and religious borders between Christians, Jews and Muslims, and on processes of religious and cultural passages, entanglement and dis/integration among the members of the three monotheisms, especially in the Carolingian and Iberian Worlds.

    I work in mathematical analysis. My research deals with complex analysis, Fourier analysis and geometric measure theory. Particularly, I am interested in the relationship between analytic notions such as analytic capacity or harmonic measure, and geometric concepts like rectifiability. In a sense, analytic capacity measures how much a set in the plane is visible or invisible for analytic functions. On the other hand, rectifiability tells you if a set is contained in a countable collection of curves with finite length. Around 2002 I proved that analytic capacity is semiadditive. This was an open problem since the early 1960s. More recently I have studied related problems in higher dimensions. In particular, in a collaboration with F. Nazarov and A. Volberg I have proved the so called David-Semmes conjecture in the codimension 1 case. This result has important applications to the study of harmonic measure, which is another of my main interests.
