EXPERIENCE
Associate Consultant (Jul. 2025 – Present)
ZS Associates (Boston, MA)
Senior Bioinformatics Scientist (Jan. 2022 – Oct. 2024)
Parexel International (Remote)
- Streamlined latency of data delivery by 10x for a major pharmaceutical client by developing novel data ingestion pipelines in R, Python, and Bash to drive biomarker discovery
- Collaborated across bioinformatics and data engineering teams to deliver 1000s of genomic datasets (GWAS & eQTL) scaling to terabytes in size, integrating data and metadata from UK Biobank, 1000 Genomes Project, FinnGen, Open Targets, GWAS Catalog, and more
- Automated high-throughput quality control workflows to enable 24-hour client turnaround
Postdoctoral Researcher (Jun. 2018 – Jan. 2022)
University of Texas Southwestern Medical Center (Dallas, TX)
- Led a multi-group collaboration to publish novel single-cell RNA-seq datasets in neurobiology, resulting in a co-first-author paper in Science (145+ citations) and a second-author paper in Nature Communications (30+ citations)
- Independently analyzed large-scale single-cell RNA-seq data by applying computational pipelines, dataset integration, unsupervised clustering (k-nearest neighbor + Louvain method), and statistical modeling to generate biological insights across research domains
- Delivered spatial transcriptomics capabilities to research group, encompassing molecular library preparation, data and analytics pipelines, documentation, and training for new users
INDEPENDENT PROJECTS
Project ESPAÑOL (https://github.com/dmerullo/project-espanol)
- Generated a dataset of 10,000+ Spanish-language poems (>2.5 million words) using high-throughput web scraping (rvest)
- Developed an unsupervised clustering (k-means) pipeline in Python to classify poems into 4 difficultly levels based on verb usage
- Built an interactive Plotly Dash web application for text exploration and visualization
