Warnow T, Tabatabaee Y, Evans S
J Comput Biol
. 2024 Nov;
32(1):3-27.
PMID: 39582425
We address the problem of how to estimate a phylogenetic network when given single-nucleotide polymorphisms (i.e., SNPs, or bi-allelic markers that have evolved under the infinite sites assumption). We focus...

Mean-field interacting multi-type birth-death processes with a view to applications in phylodynamics
DeWitt W, Evans S, Hiesmayr E, Hummel S
Theor Popul Biol
. 2024 Jul;
159:1-12.
PMID: 39019333
Multi-type birth-death processes underlie approaches for inferring evolutionary dynamics from phylogenetic trees across biological scales, ranging from deep-time species macroevolution to rapid viral evolution and somatic cellular proliferation. A limitation...

Evans S, Hening A
Stoch Process Their Appl
. 2019 Nov;
129(5):1622-1658.
PMID: 31680715
Suppose that ( ) is a one-dimensional Brownian motion with negative drift -. It is possible to make sense of conditioning this process to be in the state 0 at...

Evans S, Lanoue D
Adv Appl Math
. 2018 Sep;
96:39-75.
PMID: 30220760
Given an edge-weighted tree with leaves, sample the leaves uniformly at random without replacement and let , 2 ≤ ≤ , be the length of the subtree spanned by the...

Choi H, Evans S
Stoch Process Their Appl
. 2017 Oct;
127(7):2428-2445.
PMID: 28966434
We consider a Markov chain that iteratively generates a sequence of random finite words in such a way that the word is uniformly distributed over the set of words of...

Evans S, Molchanov I
Trans Am Math Soc
. 2017 Jan;
369(3):1797-1834.
PMID: 28065980
A metric measure space is a complete, separable metric space equipped with a probability measure that has full support. Two such spaces are equivalent if they are isometric as metric...

Schraiber J, Evans S, Slatkin M
Genetics
. 2016 Mar;
203(1):493-511.
PMID: 27010022
The advent of accessible ancient DNA technology now allows the direct ascertainment of allele frequencies in ancestral populations, thereby enabling the use of allele frequency time series to detect and...

Evans S, Hening A, Schreiber S
J Math Biol
. 2014 Aug;
71(2):325-59.
PMID: 25151369
We consider a population living in a patchy environment that varies stochastically in space and time. The population is composed of two morphs (that is, individuals of the same species...

Wachter K, Steinsaltz D, Evans S
Proc Natl Acad Sci U S A
. 2014 Jul;
111 Suppl 3:10846-53.
PMID: 25024186
Evolutionary processes of natural selection may be expected to leave their mark on age patterns of survival and reproduction. Demographic theory includes three main strands--mutation accumulation, stochastic vitality, and optimal...

Schraiber J, Griffiths R, Evans S
Theor Popul Biol
. 2013 Sep;
89:64-74.
PMID: 24001410
We investigate the properties of a Wright-Fisher diffusion process starting at frequency x at time 0 and conditioned to be at frequency y at time T. Such a process is...
