Hi there 👋 I'm @alextssheehan

  • 🔨 I currently work as: A Postdoctoral Research Fellow in the Centre for Integrative Neuroscience & Neurodynamics (CINN) at the University of Reading

  • ⚙️ I’m currently working on: Bi-/multilingual neurocognitive adaptation, brain dynamics, dynamical & complex systems, emergentist theory, study design development, entropy, neural complexity, fractal dimension, Lidenmayer System grammars, Bash scripting, pipeline automation, linguistic distance, functional connectivity, neural energetics & efficiency

  • 🧠 I’m currently learning: Simultaneous EEG-fNIRS, multivariate temporal response function analysis, signal complexity analysis, group iterative model estimation

  • 👀 I’m interested in: R, MRI analysis, EEG analysis, E-Prime, MATLAB, Python, neuroscience, psycholinguistics, neurolinguistics, cognitive psychology, consciousness, quantitative statistics (including GAMs & Bayesian statistics), novel research & analysis methods development, open-source tools, open science practices

  • 🌐 You can find me on: ORCID, ResearchGate, Google Scholar, CINN website, LinkedIn
