Experience
-
2025 - Present Postdoctoral Researcher
Johns Hopkins University School of Medicine, Baltimore, Maryland - Advisor: Dr. Kristin Bigos
- Developed a custom BIDS converter for multi-session pharmacological fMRI data lacking source DICOM/JSONs, reconstructing metadata from image headers and vendor documentation to enable integration with modern analysis pipelines (GitHub)
- Established the lab's first scalable neuroimaging infrastructure by migrating local GUI-based workflows to reproducible, containerized HPC pipelines using Apptainer with version-pinned neuroimaging tools (e.g., fMRIPrep, AFNI, FSL)
- Built an end-to-end fMRI analysis pipeline using SLURM job arrays and dependencies to parallelize and chain first-level GLM/gPPI modeling, parametric and nonparametric group inference, MNI region labeling, and subject-level cluster beta extraction (GitHub)
-
2019 - 2025 Graduate Researcher
Florida International University, Miami, Florida - Advisor: Dr. Angela Laird
- Developed and published a k-means clustering pipeline to characterize dynamic brain state transitions in longitudinal fMRI data, identifying distinct transition patterns across timepoints
- Applied mixed effects, structural equation, and latent profile models to multi-session fMRI and behavioral data to identify dissociable brain-behavioral profiles, contributing to two peer-reviewed publications
- Analyzed staff demographic data for the ABCD Study consortium, implementing hypothesis testing and data visualization to inform decisions for a multi-site research task force (GitHub)

Graduate Researcher
-
2019 Medical Laboratory Scientist I
Florida Department of Health, Miami, Florida - Conducted confirmatory diagnostic testing for HIV and syphilis for public health surveillance programs
Open-Source Projects
-
2025 - Present NIfTI2BIDS
- Developed a Python package for post-hoc BIDS conversion of NIfTI datasets lacking source DICOMs, reconstructing JSON sidecars with acquisition metadata derived from image headers
- Built configurable parsers for Presentation and E-Prime behavioral logs, automating timing and accuracy extraction for block and event-related fMRI designs into BIDS-compliant events files
- Implemented cross-platform testing across Python 3.10-3.14 on Linux, macOS, and Windows, maintaining >90% code coverage
-
2024 - Present NeuroCAPs
- Built a Python package for brain state classification using k-means, with multiprocessing for multi-subject timeseries extraction
- Incorporated clustering validation (e.g., Davies-Bouldin, Silhouette), KD-tree interpolation for volumetric-to-surface mapping, temporal dynamics metrics (e.g., transition probabilities), and integrated visualizations (e.g., surface maps, network alignment)
- Deployed via Docker with headless VTK rendering and CLI/Jupyter interfaces; maintained >90% test coverage across several OS platforms using pytest and GitHub Actions
-
2023 - Present vswift
- Created an R package for ML model evaluation, implementing custom stratified sampling, cross-validation, and nested cross-validation for hyperparameter tuning, with parallel processing support at the fold-level
- Designed a unified interface supporting classification algorithms (e.g., Regularized Logistic Regression, SVM, XGBoost, Neural Networks) while preserving algorithm-specific parameter tuning
- Incorporated automated missing data imputation and multi-metric performance assessment (e.g., precision, recall, F1) with CLI output and visualizations, including ROC and Precision-Recall curves with AUC scores
Teaching & Workshops
