Provisioning of public health can be designed to anticipate public
policy responses. By Jing Li, D. V. Lindberg, R. A. Smith,
and T. Reluga.

Bulletin of Mathematical Biology, 79(1) 163190, January, 2017.

This is one of my favorite papers  I think the mathematics is simple and
beautiful. But it was a 6 year ordeal to get it published. In
the mean time,
Wells et al, 2013 were expanding on our ideas, and Fenichel and Zhao,2014 have discussed further the ecological relevance of strategic complementarity and substituability.

 Some of the same techniques have been used by Yan and Feng (2010) to rank isolation and quarantine control performance. Amanda Ramacharan did a writeup on this for Penn State News, picked up by UPI and Science Daily.

Resource distribution drives the adoption of migratory, partially migratory, or residential strategies.
By T. Reluga and A. Shaw.
 Theoretical Ecology, March, 2015.

This is a beautiful little analysis of a spatially explicit seasonal migration model that shows how seasonality, movement costs, and resource heterogeneity can
conspire to drive coexistence, and potentially, speciation. A number of results can be obtained by hand, but there are also some open mathematical questions.

Optimal migratory behavior in spatiallyexplicit seasonal environments. By Timothy Reluga and Allison Shaw.

(Special issue in honor of Chris Cosner on the occasion of his 60th birthday, Submitted July, 2013).
I think this kind of model need some further attention. For example, I've
never been particularly happy with the economics idea of discounting, and my
work in this paper and my early paper on the discounted
reproductive number haven't asuaged my concerns. Somebody can probably
do a good job improving things with some densitydependent simulation models.

Analysis of hepatitis C virus infection models with hepatocyte homeostasis.
By T. Reluga, H. Dahari, and A. S. Perelson.
 SIAM Journal on Applied Mathematics, 69 (4):

This paper provides a complete bifurcation analysis of Harel's

predict clearance, partial infection, and bistability.
The analysis has been subsequently discussed by
DebRoy, Bolker, and Martcheva, 2009.

Backward bifurcations and multiple equilibria in epidemic models with
structured immunity. By T. Reluga, J. Medlock, and A. Perelson.
 Journal of Theoretical Biology, 252 (1): 155165, 2008.
One of the issues that bugged me when first learning mathematical epidemiology
was that it completely ignored the internal state of
the hosts changed because of immune responses. How did we know that theories which ignored the complexities of the immune response within individuals were adequate to explain populationscale dynamics? This paper is a step forward in resolving this by constructing some specific hypotheses and conditions.
(update 201208: Our results are nicely complementary to those in an earlier paper by
Hethcote, Yi, and Jing, 1999, which we were unaware of in 2008.)

Optimal timing of disease transmission in an agestructured population. By
T. Reluga, J. Medlock, E. Poolman, and A. Galvani.
 Bulletin of Mathematical Biology, 69 (8): 27112722, 2007.
This paper studies how agedependent virulence can lead to a a
socialdistancing game with two different Nash equilibria  one that
maximizes transmission and one that minimizes transmission. This is closely
related to the concept of ``endemic stability'' from veterinary science
and the paradox of moderate control in public health.
Polio is used as an illustrative example.

Reservoir interactions and disease emergence.
By T. Reluga, D. B. Walton, R. Meza, and A. Galvani.
 Theoretical Population Biology, 72 (3):
400408, 2007.
This paper provides a modelling framework for the study of diseaseemergence pathways. This is a concrete approach to riskassessment
associated with emergence patterns like those proposed by Wolfe et al..
It's model analysis contains some useful discussions of reducible branching
processes and the multivariable form of L'Hopital's rule. L'Hopital's rule is
particularly useful for multivariable generating functions because critical
processes are sure to have a double root.

A model of spatial epidemic spread when individuals move within overlapping
home ranges. By T. Reluga, J. Medlock, and A. Galvani.
 Bulletin of Mathematical Biology, 68 (2):
401416, February 2006.
This paper uses an OrnsteinUhlenbeck process to describe spatial
movement and obtains some asymptotic results for the speed of spatial spread
of an epidemic. It provides a resolution to the problem of
whether spatial epidemic spread is governed by distributed
contacts or distribution of infected, without resorting to
Baysian melding approaches.
A more recent paper exploiting this idea to a different conclusion
is by Kenkre and Sugaya (2014).

A twophase epidemic driven by diffusion. By T. Reluga.
 Journal of Theoretical Biology, 229 (2): 249261, July 21 2004.
This paper shows how a doubleepidemic might emerge from a
bioterrorism attack. In an important special case, travelling epidemic waves
can emerge even when only driven by a bioterrorism agent in 1 or 2 dimensions.
This is a pretty strange effect, and yet another example of how 3 dimensions are
special. This also provides an explanation of anomolous travelling wave speeds
found by J. Cooke.
Weinberge, Lewis, and Li (2007) have since shown that reducible systems in general can
yield anomoulus spreading speeds.
