Aalto Science Fellows
AScI Alumni fellows
Per Austrin was born in Sweden. He received his PhD in 2008 from the Royal Institute of Technology in Stockholm, Sweden. Following this he spent a semester at Institut MittagLeffler, one year at New York University as a Research Scientist, and two years at the University of Toronto as a postdoc. His research area is computational complexity, with a focus on approximation algorithms and their limitations. From the beginning of 2013 Per Austrin has been appointed as associate Professor at KTH. He continues at his Aalto Science Fellowship until summer 2013 on a parttime contract.
Marcelo Dias was born in Brazil. In 2005 he received a B.Sc. degree in Physics from the State University of São Paulo, Brazil. He continued on the academic path and received a M.Sc. in Theoretical Physics from the same university in 2007. In the fall of 2007, he started the physics graduate program at the University of Massachusetts Amherst, USA. During that time his research focused on problems related to soft condensed matter, more specifically the geometry and mechanics of shape formation in nature and in engineer applications. He received his Ph.D. degree in Physics in September of 2012. Soon after, he joined the School of Engineering at Brown University as a Postdoctoral Research Associate, where he worked on questions related to biophysics, locomotion at LowReynolds number hydrodynamics, fluidstructure interactions, and shape transformation in LiquidCrystal Elastomers.
His research interests lie within a broad range of topics in theoretical soft condensed matter. He uses techniques in Differential Geometry and Continuum Mechanics to understand how mechanical properties, that an elastic body acquires, arise from a careful design of its internal geometry rather than from its material composition. Understanding these questions is relevant to shine light on topics such as shape formation in nature, biomechanics, mechanics of structured materials, controlled design and functionality of thin plates and shells. Marcelo Dias's fellowship is together with Nordita.
Viveka Erlandsson was born in Sweden. She received her B.Sci. and MA degrees in mathematics from San Francisco State University, and her PhD degree in mathematics from the City University of New York.
Her research interests lie in hyperbolic geometry and its related fields. In particular she studies higher dimensional real as well as complex hyperbolic spaces, and the discrete groups and quasiisometries acting on these spaces. She defended her thesis entitled "The Margulis region in hyperbolic 4space" in 2013.
Filippo Federici Canova (2015–2017)
Filippo was born in Italy where he got an M.Sc. in experimental physics. He then moved to Helsinki and Tampere where, in September 2012, he obtained a Ph.D. in computational physics, focussing on theoretical modelling of atomic force microscopy. Right after graduation he went to Tohoku University, Japan, where he worked as associate researcher until January 2015.
During his research career, he collected experience of various computational tools for solving physics problems, such as molecular dynamics and abinitio calculations, up to meso and macroscale modelling. His recent activities include the study of atomicscale friction and lubrication dynamics of ionic liquids, and in particular, how to connect atomistic simulations to macroscopic measurements using multiscale models. Among his interest also include machinelearning techniques such as neural networks and evolutionary algorithm, and their application to physical problems.
Eve Hoggan was born in the UK. She received her M.A. in Computing Science and Music in 2005 and Ph.D. in Computing Science in 2010 from the University of Glasgow, UK. During her Ph.D. she undertook internships in Nokia Research Center, Helsinki and Telefonica I+D, Barcelona. Following her Ph.D., she spent 3 years at the University of Helsinki as a postdoc. Her thesis was entitled “Crossmodal Audio and Tactile Interaction with Mobile Touchscreens”.
Her current research focuses on the creation of novel interaction techniques, interpersonal communication and nonvisual multimodal feedback. The aim of her research is to use multimodal interaction and varying form factors to create more natural and effortless methods of interaction between humans and technology regardless of any situational or physical impairment. Eve Hoggan's fellowship is mainly funded by Academy of Finland postdoctoral researcher grant.
Kaie Kubjas was born in Tartu, Estonia. She received her undergraduate degree in mathematics from University of Tartu. She moved to Berlin for her graduate studies and will be completing her PhD in mathematics in May 2013 at Free University Berlin. During her doctorate she studied algebraic and combinatorial properties of statistical models coming from evolutionary biology.
Her main research interest is applying combinatorial methods to problems coming from applications.
Daniel RayneauKirkhope (2012–2015)
Daniel RayneauKirkhope was born in Oxford, UK. He received an M.Sci. degree in Mathematical Physics in 2008 from the University of Nottingham (UK), completing a masters research project in the field of random sequential adsorption. Continuing work at the University of Nottingham he completed his Ph.D. in physics with a thesis entitled “Statistical Physics of Structural Design” (2012).
His current research focuses on problems of structural optimisation approached through both analytic and computational methods. Examples of highly complex architectures achieving particular structural properties are widespread in nature: the tendon as a tension bearing linkage, the bone as a structural scaffold and the cellulose aggregates in wood for structural stability, to name but a few. The functionality of these examples depends on structural hierarchy: the structure’s stability at one lengthscale is dependent on a substructure of a smaller lengthscale (this substructure may or may not have internal, nontrivial, substructure). The effect of this hierarchy and the theoretical limit of fractal design has been a particular focus of much of his work. Daniel RayneauKirkhope received Academy of Finland's Postdoctoral Researcher's funding and continued his research at the Aalto University School of Science Department of Applied Physics research group on Molecular Materials.
Cordian Riener was born in Memmingen, Bavaria. After finishing Gymnasium (highschool) he started to study Mathematical Economics in Ulm, where he in 2003 also began studies towards a Bachelor of Philosophy degree. In 2004 he was studying in Bordeaux, France, where he graduated with a Master's degree in Mathematics. Back in Germany Riener did an internship in a bank before finishing his Mathematical Economics and Philosophy studies. In 2007 he began his PhD in Mathematics at the University of Frankfurt, under the supervision of Thorsten Theobald. He defended his thesis "Symmetries in Semidefinite and Polynomial Optimization" in 2011. Since April 2011 he has been an Associated Fellow at the Zukunftskolleg at the University of Konstanz.
His research focuses on optimization whereby he tries to exploit structure in order to make hard problems easier.
Louis Theran was born in Boston, Massachusetts. He received a BS (2005), MS (2006), and PhD (2010) in Computer Science from the University of Massachusetts, Amherst. Theran has held postdoctoral appointments at Temple University and Freie Universität Berlin. Additionally, he has been on the research staff at the Open Software Foundation and Nokia Research Center.
