What the Program Offers

BDSY blends structured learning, hands-on research, and career preparation. Instead of focusing only on lectures or only on research, it balances both in a way that builds confidence and practical skills.

Key components include:

Morning Lectures
Students attend daily sessions taught by Yale faculty and graduate researchers. Topics include:

• Statistical reasoning
• Epidemiology
• Cloud, parallel, and distributed computing
• Machine learning
• Medical informatics
• Data ethics
• Graphical models
• Precision medicine
• Data integration, management, and visualization

Mentored Research Projects
Afternoons are dedicated to collaborative research. Students work in teams on projects in areas such as:

• Infectious disease modeling
• Genomics
• Causal inference

These projects use real datasets, giving students a true research experience rather than simulated exercises.

Professional Development and Career Exposure
The program includes dedicated sessions on:

• Graduate school preparation
• Research communication
• Networking strategies
• Career paths in data-heavy fields

Journey lectures introduce students to different professional roles within data science and public health.

Ethics and Responsible Data Use
Students receive training focused on:

• Privacy and confidentiality
• Bias, fairness, and equitable data practices
• Responsible research design

This gives participants a strong ethical foundation to guide their future academic or professional work.

Funding and Support

BDSY aims to remove financial barriers so students can focus fully on learning and research. Participants receive:

• On-campus housing for the entire six weeks
• A $1,600 stipend
• Up to $750 in travel support
• A $750 meal allowance

This makes the program accessible to students from a wide range of backgrounds.

What Makes BDSY Different

Several features distinguish BDSY from other summer programs:

• It is interdisciplinary, connecting public health, statistics, computer science, and engineering.
• Students gain direct mentorship from Yale faculty and graduate students across multiple departments.
• The program is research-driven, encouraging students to think like scientists rather than just learners.
• Participants work on real health data, not toy examples or simplified assignments.
• It is funded by the NIH, which strengthens its academic credibility and long-term value for graduate school applications.

The collaborative structure also helps students build communication, teamwork, and presentation skills, all essential for careers in data science and research.

Who Should Consider Applying

BDSY is an excellent fit for students who:

• Enjoy working with data, statistics, or programming
• Are curious about public health, medicine, or scientific research
• Are you planning to pursue graduate studies (MS or PhD)
• Want research experience but don’t know where to start
• Are interested in interdisciplinary learning
• Want to understand how data can change health outcomes and decision-making

Academic majors that often benefit include:

• Statistics
• Computer science
• Biology
• Math
• Engineering
• Public health
• Neuroscience
• Bioinformatics

You do not need prior research experience. A genuine interest in quantitative thinking and a willingness to learn are what matter most.

Application Requirements

Applicants must submit one PDF containing:

• A personal statement (up to 2 pages)
• A resume or CV
• Unofficial transcripts

At least one academic reference is required. This should be someone who can speak to your academic potential, especially in quantitative or research-focused courses.
