Belay Gebregergis

Computational Neuroscientist | PhD | Building production-ready ML pipelines for biotech and neuroscience

I apply machine learning and advanced signal processing to neural recordings — translating electrophysiology data into biological insight. My work spans seizure detection, spectral analysis, connectivity, cross-frequency coupling, signal complexity, and sleep staging.


EEG Analysis Portfolio — C9orf72 Mouse Model of ALS/FTD

Six end-to-end analysis pipelines applied to longitudinal dual-channel hippocampal CA3 + cortex EEG recordings from WT and C9orf72-KO mice across 3, 6, and 12 months.

Repository Analysis Key methods
eeg-seizure-detection Automated SAD detection + ML classifier Adaptive thresholding, Random Forest, ROC-AUC 0.85
eeg-spectral-analysis-c9orf72 Longitudinal band power, CA3 + cortex Welch PSD, Mann-Whitney U, heatmaps
eeg-connectivity-c9orf72 Hippocampal-cortical connectivity Coherence, PLV, Granger causality, transfer entropy
eeg-cross-frequency-coupling-c9orf72 Phase-amplitude coupling Modulation Index, comodulogram, cross-channel PAC
eeg-signal-complexity-c9orf72 Signal complexity SampEn, MSE, permutation entropy, LZC, Hjorth
eeg-sleep-wake-c9orf72 Sleep-wake classification Rule-based staging, state proportions, state-specific analysis

Key finding: C9orf72-KO mice show a U-shaped elevation in theta band power (4–8 Hz) at 3 and 12 months with convergence at 6 months in both CA3 and cortex — consistent with progressive network dysfunction in ALS/FTD.
