# Estimating superinfection prevalence

We have published 2 papers in the last year related to superinfection. That is the phenomenon by which a single … More

# Stochastic solvers for dynamical systems

So there are two main ways that we might typically take a dynamical system (expressed as a set of interacting … More

# Compound interest cure

So I guess I never got around to summarizing our paper published last year in Scientific Reports (PAPER). The paper … More

# Immunology is a complex/nonlinear system, which is cool…

if you like typically analytically intractable math. The humanist motivations for studying immunology are, frankly, trivial to state. But what … More

# Euler’s Proof

I was reminded of Euler’s proof that there are infinitely many prime numbers in reading my new (used) copy of … More

# Extinction in an HIV model

Via Professor Jessica Conway’s really nice paper and complete notes in her supplementary file, I’m redoing a calculation for my own … More

# Lognormal and power law distributions

Where does a log-normal distribution “come from”? The log-normal distribution shows up all over the place because it arises from a quite … More

# Hyrien tricks for model fitting

In meeting with Ollivier recently, we discussed the proper approach for fitting a dynamical system model to time series data, … More
