Bio

Gabriel Falcao graduated in Electrical and Computer Engineering from the University of Porto where he also concluded a M.Sc. degree in Digital Signal Processing. He received the Ph.D. degree from the University of Coimbra (UC) in 2010 in the area of parallel computer architectures. He is an Assistant Professor at the Department of Electrical and Computer Engineering of the UC since December 2010 and a researcher of Instituto de Telecomunicações (IT) since 2004. In 2011/12 (and again in 2017/18) Gabriel Falcao was a Visiting Professor at EPFL, Switzerland, where he developed work trying to bridge the worlds of CPU, GPU and FPGA parallel computer architectures. In the summer of 2018 he became a Visiting Scholar at ETHZ, Switzerland, working on novel processing-in-memory solutions. His research interests include the development of novel low-power parallel computing paradigms to deal with compute-intensive signal processing scenarios, in particular those related with image and data communications. Gabriel Falcao is the PI of a CUDA Research Center at the Multimedia Signal Processing Lab, a R&D unit in IT hosted at the Department of Electrical and Computer Engineering of the UC. He has successfully supervised more than 20 MSc students and 4 PhD students (2 completed), published over 90 papers in international journals and conferences, and holds an international patent (Europe, USA, Japan). He is a member of the HiPEAC Network of Excellence, of the IEEE Signal Processing Society and an IEEE Senior Member.

  • D. E. Fernandes, M. Rodrigues, G. Falcão, M. G. Silveirinha, Prémio ANACOM-URSI 2015, The ANACOM-URSI Portugal Prize was assigned to “Diffractionless Propagation of Electron Waves in Graphene Superlattices”. In this work we used a homemade Finite Difference in the Time Domain (FDTD) algorithm to characterize the propagation of electron waves in graphene. The algorithm was applied to study the dynamics of electrons in graphene superlattices, using both microscopic and effective medium approaches. In particular, it is shown that the time evolution of an electronic state and the propagation of stationary electronic states may be accurately predicted with the effective medium formalism, provided the initial state is less localized than the characteristic spatial period of the superlattice. Our results confirmed that electrons propagating in graphene superlattices with extreme anisotropy experience virtually no diffraction, 01-12-2015
