Experience
-
2025 - Current Postdoctoral Researcher
Johns Hopkins University School of Medicine, Baltimore, Maryland - Built automated pipelines to convert unstructured neuroimaging and behavioral datasets to BIDS-compliant format for integration with modern analysis tools
- Migrated workflows to HPC clusters and containerized pipelines with Singularity to ensure consistent execution across compute environments
-
2019 - 2025 Graduate Researcher
Florida International University, Miami, Florida - Developed a k-means clustering pipeline to characterize dynamic brain state changes associated with learning in longitudinal fMRI timeseries data
- Built post-processing pipelines using fMRIPrep and MRIQC to extract and denoise timeseries data, minimizing motion artifacts and increasing signal-to-noise for downstream statistical modeling
- Created statistical models (e.g. Linear Mixed Effects, Structural Equation Modeling, Latent Profile Analysis) to examine brain-behavioral relationships
- Analyzed staff demographic data for the ABCD Study consortium using R, implementing hypothesis testing and data visualization to inform decisions for a multi-site research task force
- Designed and delivered an introductory workshop on R programming and Tidyverse for the Diversity, Equity, and Inclusion program, instructing 20+ graduate students on data manipulation and visualization
- Provided statistical consultation on collaborative projects, applying latent and linear methods to neuroimaging and tabular data
-
2020 - 2022 Graduate Teaching Assistant
Florida International University, Miami, Florida - Provided instructional support and targeted tutoring for undergraduate psychology statistics courses
-
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 Software
-
2025 - Current nifti2bids
- Developed a Python package to standardize unstructured neuroimaging datasets by creating utilities to create and extract metadata information (e.g. single and multi-band slice timing) from NIfTI headers for BIDS sidecar generation
- Created tools to parse and convert semi-structured behavioral experiment data (including proprietary E-Prime formats) into BIDS-compliant event files
-
2024 - Current NeuroCAPs
- Developed a Python package for fMRI brain state identification using k-means, achieving 5x faster multi-subject processing via multiprocessing with checkpointing support
- Incorporated clustering validation (e.g. Davies-Bouldin, Silhouette), KD-tree interpolation for volumetric-to-surface mapping, temporal dynamics metrics (e.g. transition probabilities), and an interactive visualization suite
- Deployed via Docker with headless VTK rendering and CLI/Jupyter interfaces; maintained >90% test coverage across OS platforms using pytest and GitHub Actions
-
2023 - Current 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 (precision, recall, F1) with CLI output and visualizations, including ROC and Precision-Recall curves with AUC scores using trapezoidal rule
