About this course

Background for Research in the Rob Phillips Physical Biology Laboratory This independent educational primer introduces scientific concepts relevant to research themes in the Rob Phillips Physical Biology Laboratory at the California Institute of Technology. It is not an official Caltech or Rob Phillips Laboratory course and does not imply endorsement or affiliation. For ambitious high-school students and early undergraduates with high-school biology and algebra; probability is helpful. Approximately 40–45 minutes including six video-first lessons and assessments. Mastery-only certificate eligibility at 80%, without a capstone or Research Defense.

Syllabus

Module 1

Quantitative Biology and Gene Regulation

Counting, minimal models, and sequence-to-expression measurements.

Module 2

Life Out of Equilibrium

Energy, fidelity, collective materials, and viral ecology.

Concepts you'll master

  • Active matter and molecular motor energy consumption

    Identify local energy consumption in active materials.

  • Binding energy, occupancy, fold-change, and allostery

    Connect copy number, binding energy, fold-change, and ligand-dependent allostery.

  • Biological fidelity, energy expenditure, and error correction

    Explain why fidelity requires mechanism-specific coupling and evidence.

  • Biological numeracy, scale, and order-of-magnitude reasoning

    Estimate biological quantities with units and order-of-magnitude reasoning.

  • Coarse-graining and predictive minimal models

    Distinguish a minimal model, a fitted parameter, and a prospective prediction.

  • Collective microtubule–motor dynamics and emergence

    Connect motor interactions to emergent microtubule dynamics and measurements.

  • Equilibrium versus nonequilibrium biological processes

    Distinguish equilibrium discrimination from driven processes.

  • From measurement to model across biological scales

    Apply measurement-to-model reasoning while preserving causal limits.

  • Information footprints and regulatory-architecture inference

    Interpret information footprints without claiming protein identification.

  • Quantitative viral genomics and bacteriophage ecology

    Interpret viral-genomics and phage-ecology observations within their dataset.

  • Regulatory DNA and massively parallel sequence-to-expression measurement

    Explain sequence-to-expression reporter measurements.

  • Statistical mechanics of transcriptional regulation

    Relate statistical weights to occupancy under stated assumptions.
