## Abstract

Big Data Predictive Phylogenetics with Bayesian Learning
Abstract
Andrew Holbrook, Ph.D., is a Bayesian statistician with a broad background in applied, theoretical and compu-
tational data science. His proposed research Big Data Predictive Phylogenetics with Bayesian Learning tackles
viral outbreak forecasting by combining Bayesian phylogenetic modeling with ﬂexible, `self-exciting' stochastic
process models. The development and publication of open-source, high-performance computing software for his
models will facilitate fast epidemiological ﬁeld response in a big data setting. Dr. Holbrook will apply his method-
ology to the reconstruction of the 2015-2016 Zika virus epidemic in the Americas, focusing on identifying key
geographical routes of transmission and phylogenetic clades with enhanced infectiousness.
 Candidate: Dr. Holbrook is Postdoctoral Scholar at the UCLA Department of Human Genetics. He earned his
Ph.D. in Statistics from the Department of Statistics at UC Irvine, during which time he completed his dissertation
Geometric Bayes, an investigation into Bayesian modeling and computing on abstract mathematical spaces, and
simultaneously participated in scientiﬁc collaborations at the UC Irvine Alzheimer's Disease Research Center.
The proposed career development plan will establish Dr. Holbrook as an independent leader in data intensive
viral epidemiology by 1) facilitating coursework to build biological domain knowledge, 2) affording Dr. Holbrook
the opportunity to lead his own project while remaining under the expert oversight of UCLA Prof. Marc Suchard,
M.D., Ph.D., and 3) allowing Dr. Holbrook to continue his focus on quantitative viral epidemiology once he has
moved to a faculty commitment.
 Mentors: During the ﬁrst three years of the award period, Dr. Holbrook will work closely with Prof. Suchard,
continuing their current schedule of weekly meetings. Prof. Suchard is a leading expert in both Bayesian phylo-
genetics and high-performance statistical computing; and with his medical background, Prof. Suchard will advise
Dr. Holbrook in his expansion of domain knowledge in viral epidemiology. As secondary mentor, Prof. Kristian
Andersen, Ph.D., of the Scripps Institute will advise Dr. Holbrook in the impactful application of his statistical
and computational methodologies to the 2015-2016 Zika virus epidemic. Dr. Holbrook and Profs. Suchard and
Andersen will maintain their collaborations after the postdoctoral period.
 Research: Bayesian phylogenetics successfully reconstructs evolutionary histories but fails to predict viral
spread. Self-exciting point processes are devoid of biological insight and fail to account for geographic networks
of diffusion. Aim 1 addresses deﬁciencies in these two complementary viral epidemiological modeling techniques
by innovating a combined model where the phylogenetic and self-excitatory components support each other.
Aim 2 makes widespread adoption a reality by publishing open-source, massively paral...
