João Peça, PhD - Group Leader

 

I grew up and studied in Coimbra, Portugal where I received my Licentiate degree in Biochemistry (2004, UC). During this time I worked and volunteered in the laboratories of Carlos Bandeira Duarte, Carlos Faro, Paula Veríssimo and Sandra Macedo-Ribeiro, where I gained expertise in molecular biology, protein biochemistry and cell biology. In 2005, I was selected to the BEB international PhD program and moved to Durham, North Carolina where I worked with Guoping Feng at Duke University. During my Ph.D. (2011) I created the first transgenic mice for channelrhodopsin-2, at the time a novel tool that greatly facilitated optogenetic-assisted dissection of neuronal circuitry. In 2011, I moved to MIT as a postdoctoral fellow funded by the Autism Speaks Foundation. There I characterized the Shank3 gene and uncovered a new role for cortico-striatal dysfunction in autism spectrum disorders. In 2013 I was named “FCT Investigator” and offered a position in the Synapse Biology Group at the Center for Neuroscience and Cell Biology. In 2018, I became Principal Investigator and started an independent group at CNC – the “Neuronal Circuits and Behavioral Laboratory”.

I am currently Assistant Professor at the Department of Life Sciences, Faculty of Science and Technology, University of Coimbra, teaching classes ranging from molecular biology to neuronal circuit analysis. Currently, my group is involved in several projects aimed at understanding how specific neuronal circuits control animal behavior, and the genetic and environmental effects that modulate circuit assembly and function. To achieve this we use a combination of mouse molecular genetics, in vivo and ex vivo electrophysiology, behavioral tests, optogenetic manipulations and more recently, organoid technology. To date I have been Lead PI in seven (7) , co-PI in three (3) and member of the team in two (2) grant projects. A total of 4 Ph.D. students and 10 MSc students have performed their graduate work under my direct supervision.

My work has accrued >2800 citations and as led to primary research papers in high impact, peer-reviewed journals, including Nature, Nature Communications, PNAS, and Neuron, and review work in Current Opinion in Neurobiology, Cell and Annual Reviews in Neuroscience. Recently, our work was acknowledged with the “2019 Pfizer Prize” in Basic Research, the oldest and one of the most prestigious prizes in Portugal in the area of Biomedical Sciences.

Ana Luisa Cardoso, PhD - Senior Researcher

 

I am originally from Coimbra and graduated in Biochemistry from the University of Coimbra (UC) in 2004. In the same year I received an international Ph.D scholarship to work on the development of lipid-based nanoparticles for treatment of acute brain lesions, under the supervision of Prof. Conceição Pedroso de Lima (Biochemistry Department, UC) and Prof. Sérgio Simões (Faculty of Pharmacy, UC and Bluepharma). This project was performed in collaboration with Prof. Ernst Wagner (Faculty of Pharmacy, LMU, Munich, Germany) and Prof. Nikolaus Plesnila (Institute for Stroke and Dementia Research, LMU), giving me the opportunity to work in both their laboratories between 2006 and 2007.
After obtaining my Ph.D. in Biochemical Technology in 2008, I integrated CNC.IBILI as a Post Doc, aiming to investigate the role of miRNA deregulation in CNS diseases, including glioblastoma and Alzheimer’s disease (AD). In 2013, I was granted a two-year position as Invited Assistant Investigator at UC to work in the EU funded project “New strategies to manage brain diseases” and from 2013 to 2016 I was able to focus my research in the field that I am truly passionate about, which is Neuroimmunology. During this period, I investigated the contribution of miRNAs to the modulation of brain immunity and microglia function, which allowed me to start my trek to scientific independence.

In 2017, I accepted a new professional challenge and integrated, as a Senior Researcher, the recently formed Neuronal Circuits and Behavior Group, led by Dr. João Peça. My most recent work has focused on understanding the crosstalk between the immune system and neuronal homeostasis mechanisms, with the ultimate goal of unveiling the role of chronic and acute neuroinflammatory events, such as those observed following exposure to early life stress, in synaptic architecture and in the development of neuropsychiatric and neurodegenerative disorders.

Since 2005 I have published 34 peer-review papers, including original work in Nature Communications, Neuropsychopharmacology, Journal of Controlled Release and Alzheimer & Dementia, as well as reviews in Aging Research Reviews and Expert Opinion in Pharmacology. I have also successfully supervised 9 Master and 3 Ph.D students and organized/participated in several international Advanced Courses, academic juries and international Consortiums.

Catarina Seabra, PhD

 

I initiated my scientific path at the University of Aveiro where I enrolled in the Biomedical Sciences course followed by a Master’s degree in Molecular Biomedicine. My first scientific project was developed at the Population Genetics Group, at IPATIMUP, Porto, with a focus on the genetic variants underlying male infertility. For my PhD, I was selected for the competitive GABBA Program of the University of Porto, which allowed me to obtain international experience in Boston, USA, at the Molecular Neurogenetics Unit of the Center for Genomic Medicine and Broad Institute of MIT and Harvard. During this period, I built a strong background in different scientific fields from human genetics to neurodevelopment, stem cells and gene editing with CRISPR/Cas9, as I worked on the functional genetics of autism and contributed to publications in journals such as Nature Genetics, Nature Neuroscience and Molecular Autism.

In 2018, I was awarded a Marie Skłodowska-Curie Individual Fellowship by the European Commission to implement a novel line of research at the Peça Lab, Center for Neuroscience and Cell Biology (CNC), Coimbra, to develop 3D brain organoids to study neurodevelopmental disorders such as autism, in collaboration with the Pediatric Hospital of Coimbra (HP-CHUC, EPE) and the Faculty of Medicine (FMUC). As an educator, I have supervised undergraduate, Master and PhD students and taught advanced PhD-level courses at the University of Coimbra. Besides, I am an avid advocate of public engagement and education outreach and had the opportunity to reach large audiences through interviews for different media channels from national television to radio. 

Joana Guedes, PhD

 

I am originally from Oeiras, although I moved to the north of Portugal at the age of 10. Coimbra was the city I choose to pursue my bachelor’s and master’s degrees in Biochemistry. In 2011, I was selected to the BEB international PhD program where I studied under the supervision of Conceição Pedroso de Lima and Ana Luísa Cardoso at the Vectors and Gene Therapy Group. During my PhD, I dissected the role of miRNAs in the phenotype of monocytes in Alzheimer’s disease. I the last year of my PhD, I was a visiting researcher at the Massachusetts General Hospital (Boston, USA) where I collaborated with Joseph El Khoury, a world-renowned neuroimmunologist.

In 2016, I started my postdoctoral studies at the Peça lab, focusing on the effects of environmental and genetic insults in neurodevelopmental disorders. Here, I had the opportunity to explore my main research interest: understand how microglia dysfunction underlie circuit and behavioral deficits. I became particularly interested in the cerebellum, a brain region involved in several neuropsychiatric disorders. Importantly, I trained as an electrophysiologist. In 2017 I was awarded a competitive FCT postdoctoral scholarship mentored by João Peça and Gouping Feng (MIT). Since then I have been involved in several research projects in the lab.

Overall, I published 15 peer-reviewed papers and book chapters, namely in high impact journals, such as Nature Communications, Neuropsychopharmacology, Journal of Neuroinflammation and Alzheimer & Dementia. Additionally, I was an author/co-author of 18 posters and oral presentations in international conferences. 

From a social point of view, I believe in bringing people together to disseminate knowledge, having participated in several outreach activities. Also, I have been part of organizations and forums, such as the Portuguese American Postgraduate Society and the CNC.IBILI postdoctoral researchers aiming at debating alternative scientific paths.
