TIME Core Room 1625

The TIME Core Biostatistics & Bioinformatics Service provides integrated quantitative and computational support for basic researchers and clinician-scientists across the research lifecycle.

Led by Dr. Omar Cruz, the service supports study design, statistical analysis, bioinformatics and reproducible research workflows, helping investigators move from project conception through analysis, interpretation and publication.

Biostatistics & Bioinformatics Services

The service provides collaborative support for both clinical and preclinical research projects.

Services include:

Experimental design consultation
Power and sample size calculations
Statistical analysis of clinical and preclinical datasets
RNA-seq, single-cell and long-read sequencing analysis
Multi-omics integration
Spatialomics data interpretation
Data visualization
Development of analysis pipelines
Machine learning applications
Guidance on data management, sharing and reproducibility

Statistical Analysis

Biostatistical support is available for a wide range of research questions, including comparisons between groups, adjustment for covariates and development of predictive or classification models.

Examples of analyses include:

t-tests
ANOVA
Kruskal-Wallis tests
Chi-square tests
Fisher’s exact tests
Adjustment for sex and other covariates
Logistic regression
Support vector machine models

Preparing your data

Data submitted for analysis should ideally be provided as a comma-delimited (.csv) file with:

No blank rows or columns
Clear and simple column headers
A separate file defining column headers where needed

Preparing data in a consistent format helps streamline analysis and reduce delays at the start of a project.

Pricing

Omar's services are free to primary appointed faculty in the Department of Medicine (DOM). For researchers outside of DOM, these services are available for $120/hour

Planning your project

Need support with study design or data analysis?

Contact Dr. Omar Cruz with a brief summary of your project. Early consultation can help ensure that study design, sample size and analysis plans are aligned with your research goals.
