Chronobiology & Circadian Medicine
Chronobiology studies biological rhythms — molecular (BMAL1/CLOCK), physiological (cortisol, melatonin), and behavioral (sleep-wake) — and applies them clinically as chronotherapy: dosing drugs, scheduling surgery, and managing shift-work fatigue based on circadian phase.
Default learning track
4 phases · ~16–22 weeksA baseline path through this sector with milestones, prerequisites, and concrete projects. Click Personalize this roadmap above to have the AI tailor pace, depth, and resources to your background and goals.
Phase 1 — Foundations
Build the conceptual and quantitative base needed to read papers and follow tutorials in the sector.
Prerequisites
- Comfortable with basic biology / health-science vocabulary
- Ability to install software and use a terminal
Skills you'll build
Hands-on projects
Walk through a published tutorial in Python + pyActigraphy + MetaCycle (R) and reproduce its results on the provided sample data.
Deliverable: GitHub repo with a Jupyter/Quarto notebook, environment.yml, and README
Milestones
- Set up reproducible Conda/Mamba environment and a public GitHub repo
- Read and summarize 3 review papers covering the sector landscape
- Complete an intro statistics or scripting course end-to-end
Phase 2 — Core tools & datasets
Learn the standard analytical stack of the sector and the canonical public datasets used by professionals.
Prerequisites
- Completed Phase 1 reproducible notebook
- Working Python/R environment
Skills you'll build
Hands-on projects
Pick one study from MESA / UK Biobank accelerometer subset + CircaDB, reproduce the headline result, and write a short technical note on what you found.
Deliverable: GitHub repo + 3-page PDF write-up
Milestones
- Run the official Python + pyActigraphy + MetaCycle (R) tutorial end-to-end on real data
- Download and explore one full dataset from MESA / UK Biobank accelerometer subset + CircaDB
- Document a clean QC + analysis pipeline that another person could rerun
Phase 3 — Applied projects
Move from tutorials to original analyses on real questions. Start showing your work publicly.
Prerequisites
- Phase 2 dataset deep-dive complete
- Comfortable with the sector's primary tooling
Skills you'll build
Hands-on projects
Extract rest-activity rhythm parameters (amplitude, acrophase, IS/IV) from a public accelerometer dataset and correlate with a health outcome.
Deliverable: Notebook + 8-page report with cosinor and non-parametric analyses
Milestones
- Ship one original mini-analysis on a public dataset with clearly stated hypothesis and limitations
- Engage with the Society for Research on Biological Rhythms (SRBR) (post a question, answer one, or share a notebook)
- Get peer feedback on at least one project and iterate
Phase 4 — Portfolio & career launch
Package your work, target real roles, and prepare to interview in the sector.
Prerequisites
- Phase 3 capstone project shipped
- 2+ public repos under version control
Skills you'll build
Hands-on projects
Curate 2–3 of your strongest sector projects into a portfolio site with clear case-study writeups, plus a 1-page CV tailored to the target role.
Deliverable: Live portfolio URL + PDF CV + cover letter template
Milestones
- Publish a portfolio site or pinned GitHub README linking to 2–3 projects
- Tailor CV to 3 real job ads in the sector and submit applications
- Practice 5 mock technical interviews with sector-specific case studies
