Research Experience
Postgraduate Scientist, National Center for Atmospheric Research: August 2010 - Current
Projects are oriented towards regional climate modeling, uncertainty quantification, and impact studies.
The SIMMER project looks at heat stress, vulnerability, and adaptive capacity in Houston. Methodology
includes survey and sampling design along with latent surface spatial models incorporating mortality and
morbidity data, census information, information related to the heat island effect, urban canyons, etc. A
second project looks at annual temperature profiles across North America using NARCCAP regional climate
models. The goal is to understand how that shape is changing in the future and the role of global climate models, regional climate models, and their interaction in that change. Methodology includes Gaussian
Markov Random Fields, Bayesian Hierarchical Modeling, and interactive graphics for model exploration. A
third project looks at Bayesian climate ensembles in the context of the NARCCAP design to identify the
roles of GCM, RCM, and their interaction.
Dissertation Research, UC Davis: September 2007 - August 2010
The majority of work was focused on developing an effective wind power forecasting method for a Solano,
California wind farm. Methodology included semi-parametric and non-parametric time series analysis and
model selection. Similar to a GLM model, we considered a link function that relates the continuous response
variable to its predictors. The goal of the second problem was to explore new ways to visualize large data
sets using interactive graphical displays and web tools such as XML, SVG, and JavaScript.
UC Davis Clinical and Translational Science Center (CTSC): September 2006 - September
2008, September 2009 - January 2009
In this graduate student research position, I was a statistical consultant to researchers at the medical school.
Analyses included longitudinal, survival, categorical, and mixed effect models in addition to regression and
ANOVA. The position was in its essence collaborative and included study design, clinical trials, data analysis, and providing written summaries to be incorporated into journal articles.
Sacramento Municipal Utility District (SMUD), Wind Energy Division: September 2007 January 2009
In collaboration with professors and staff from the UC Davis Department of Mechanical Engineering, analyzed historical data from SMUD’s Solano wind farm. This included extensive data cleaning, manipulation
of large data sets, and analysis. Delivered semi-annual reports.

UC Davis Medical School, Internal Medicine: September 2007 - September 2008
This clinical trial research position required both longitudinal data analysis and database management. In
joining the trial several years after it began, it also involved reading and interpreting the code of other
statisticians and replicating their results. Provided clear written summaries for each step of the project.
National Institute for Environmental Health Sciences, NIH: June 2005 - September 2005
During this summer internship, research centered on micro-array studies with missing values. Other topics
included multivariate analysis, order-restricted inference, and developing a method for data quality control.
Computer programs used included ORIOGEN, Ingenuity, and GOTM along with R and SAS.

Teaching Experience
Teaching Assistant: Mathematical Science of Understanding and Predicting Regional Climate:
A School and Workshop, National University of Singapore (March 2011). Developed and conducted
an introductory R boot camp for non-statisticians. Aided students in implementing course material in R.
Associate Instructor: Department of Statistics, University of California, Davis (Winter 2006,
Summer 2006, Spring 2009, Summer 2009). Instructor for Introduction to Statistics. Responsibilities included choosing a textbook, preparing lectures, exams, and homework, office hours, and supervising readers
and teaching assistants.
Teaching Assistant: Explorations in Statistics Research Workshop (June 2009, University of California, Berkeley. June 2006, University of California, Los Angeles). This weeklong workshop introduced
exceptional undergraduates to research in statistics. Worked with small groups of students to explain both
statistical concepts and programming methodology in R.
Teaching Assistant: Department of Statistics, University of California, Davis (September 2004 March 2010). Assisted for courses including Introduction to Statistics, Statistics through Computers, Statistics for the Bio-Sciences, and Methods of Teaching Statistics. Led discussions, held office hours, prepared
test questions, and graded projects and tests.
English Teacher: La Conquista, Costa Rica (May 2003 - August 2003). Volunteered at a rural middle
school teaching seventh grade English. Worked with the Costa Rican Ministry of Education, Harvard’s
Center for International Development ,and members of the community to develop appropriate curriculum.
Communicated in Spanish. Worked with limited resources.
