Physics Expert

**Role Title:** Physics Expert (Biophysics / Statistical Physics) **Role Type:** Contractor **Location:** Remote micro1 is engaging Physics Experts (Biophysics / Statistical Physics) to contribute to a research-level project focused on modeling bacterial population growth, stochastic two-state growth-rate switching, cell-size regulation noise, and asymptotic population growth rate. In this role, you'll apply your expertise to help train next-generation AI systems. Your work will shape how models learn, reason, and perform through high-quality, real-world input. No prior experience in AI is required — your domain knowledge is what matters. Participants may be considered for one or more assignments, including Solver, Auditor, or Adjudicator, based on subfield specialization, seniority, and hands-on experience with the relevant methods. **Scope of Work** 1. Analyze and model stochastic two-state Markov processes with gamma-distributed waiting times in the context of bacterial population dynamics. 2. Apply the Euler-Lotka equation to assess and benchmark asymptotic population growth rates under varying noise regimes. 3. Develop or review analytical approaches using perturbative expansions in small division-noise variance and validate resulting predictions. 4. Integrate renewal theory and first-passage-time analysis to derive key insights on population growth and cell-size regulation noise. 5. Document detailed methodological steps, assumptions, and findings clearly for AI training and reproducibility purposes. **Preferred Qualifications** 1. Advanced expertise in statistical physics, biophysics, or related quantitative biological modeling of stochastic processes. 2. Proven experience working with two-state Markov models and gamma-distributed waiting times in biological or physical systems. 3. Strong command of the Euler-Lotka equation, perturbative expansions, and renewal theory in the context of population or growth dynamics. 4. Demonstrated ability to conduct first-passage-time analysis and interpret implications for growth-rate fluctuations and size control. Originally posted on [Himalayas](https://himalayas.app)
