Experienced Data Science Leader - Driving results through advanced methodology which generates Real World Evidence

Raleigh, NC

How does this work?

As a strategy-driven Data Science Leader with a strong and consistent track record of success in helping companies to achieve their goals in the healthcare field, I am a biostatistician, physician, and epidemiologist who possesses deep experience in overseeing teams in data analytics, in building predictive machine learning/ artificial intelligence models, and in multidisciplinary problem-solving. I revel in the challenge of accomplishing goals through novel statistical method development and multidimensional data approaches. During my career, I have successfully overseen the development of production-level enterprise applications. In addition, as a leader, I have managed several employees while earning a reputation as an empowering leader. A few of my recent successes include: ► Presented a statistical model using RWE showing that HIV pre-exposure prophylaxis (PrEP) was the most important factor in the decline of the incidence of HIV cases in the United States from 2012-2017; showcased this model at the largest peer-reviewed HIV meeting (IDWeek) in 2019. ► Demonstrated that using an appropriate data model in a semi-automated approach can yield the efficient and rapid evaluation of safety signals. ► Described a complex statistical model for antimicrobial resistance based on mathematical models of bacterial transmission; this model provided a novel explanation of current and future trends.

Work experience

Feb 2012 - Dec 2020

Gilead Sciences

Executive Director of Real World Evidence / Machine Learning

In this role, I created an RWE group that utilized a data warehouse and a Hadoop data lake to carry out multiple studies using an innovative statistical methodology. I introduced in-database analytics geared toward large amounts of data, and I also added interpretable machine learning algorithms. I additionally created models that can be applied to adverse events and health outcomes. Furthermore, I developed RWE applications for risk identification and the assessment of outcomes/ efficacy given various exposures. ►One of my major achievements in this role is that I used 30+ global PrEP implementation projects over six years to establish that HIV seroconversion rates in PrEP program conditions are significantly better than those in clinical trials. I presented this result at a peer-reviewed meeting, emphasizing that the implementation of PrEP works well at the program level. ►I also helped to significantly reduce the number of false positives over the course of three years by developing a Bayesian methodology for detecting safety signals in large databases.
