Jorge Almeida

Curriculum vitae

I grew up in Lisbon, Portugal, where I received my BA in Psychology (2003; Faculty of Psychology, University of Lisbon). There I worked with Leonel Garcia Marques on topics of person perception, and Paulo Ventura on semantic memory. I then moved to Cambridge MA, USA, where I did my PhD (and MA) in Psychology at the Department of Psychology Harvard University (2011) with Alfonso Caramazza in the Cognitive Neuropsychology Laboratory and Ken Nakayama in the Vision Sciences Lab. I focused on the kinds of information that are processed unconsciously under continuous flash suppression, and on the processing of tools/manipulable objects. After my PhD I started working on the neural processing of tool items, focusing on how different types of tool-related information are processed in the brain and on how tool-related regions modulate the signal in other tool-related regions.

I am currently an Associate Professor at the Faculty of Psychology and Educational Sciences – University of Coimbra, Portugal. I am now focusing on how object-related information is mapped in the brain and how local object-selectively is defined within domain-specific networks via long-range connectivity. To do so I use fMRI, neuromodulation and behavioural testing. I am currently the PI or Co-PI in 4 FCT research projects, and the PI of the first ERC grant in the field of Psychology in Portugal – ContentMAP. My core research topics are cognitive neuroscience, object recognition, neural organization of conceptual knowledge, category specificity in the brain, neuroplasticity, and effects of neurostimulation on neural processing. To address these questions, I have the pleasure of collaborating with fantastic researchers around the world namely Bradford Mahon and the CAOs Lab now at Carnegie Mellon University; Angelika Lingnau at Regensburg University; Yanchao Bi and Fang Fang at Beijing Normal University and Peking University respectively; Mel Goodale and Jody Culham at Western University, among others. 

Most importantly, I have been fortunate to have the help of an outstanding group of researchers at the Proaction Lab – you can meet them below!

Post-Doctoral Researchers

André Peres

André Peres holds a degree in Medical Physics from the University of São Paulo (2005), a Master's (2008) and PhD (2012) from the same University. He was a postdoctoral researcher at the Brain Institute - UFRN (2012-2016) and worked as an assistant professor at the Edmond and Lily Safra International Institute of Neurosciences - Santos Dumont Institute (2016-2019). Currently, he is a Junior Researcher at PROACTION Lab.

André's academic interests are centred on the dynamics of sensory processing, the integration between sensory systems and how environmental information is perceived by individuals. In human studies, he has used fMRI combined with machine learning techniques to understand how semantic categories are organized in the brain. In animal models, he used the electrophysiology technique with multi-electrode matrices. André has been also developing methods for brain stimulation as a neuronavigation system and protocols to assess the mismatch between the measured and nominal parameters of TMS.

During his undergraduate studies, being able to participate in a research project on the effects of chronobiology and ageing on attentional processes helped to cement his aspirations for pursuing a career in cognitive neuroscience.

Currently, he is assisting in two research projects: one assessing the effects of high-frequency tRNS applied over hMT+ on coherent motion perception; the other evaluating the effects of tool affordance in spatial attentional shifts using eye-tracking. He is interested in delving into neurolinguistics and possibly memory research.

She has been collaborating with Proaction Lab since her second year of bachelor (October 2017), assisting the research by applying experiences to the subjects and analysing data with Matlab and SPSS. Her first collaboration was in a neuromodulation project involving a classical conditioning experiment (fear extinction) with transcranial direct current stimulation and its effect on anxiety. Later she began helping in a project about visual and visual-motor processing of hands and tools (ventral vs. dorsal streams), and right now Joana is focused on topics such as neuroplasticity and functional connectivity, working in projects with congenitally deaf participants, fMRI and analysing data with Brain Voyager.
