Jonathan Levy
Biography: Jonathan is a musician returning to his mathematical roots, pursuing a renaissance-view of marrying the endeavors of humanity in the face of practical specialization. His interests within biostatistics revolve around being an advocate for scientists who have critical questions and for those who need a voice from someone trained in the field of statistics, who will look at the science and literature as well as issues not related to science, to shed light on health issues, rather than simply taking refuge in the most highly promoted establishment views.

Sara Moore
Biography: Sara is a Biostatistics Ph.D. candidate in her final year of study at UC Berkeley. She received her B.A. in Computer Science and Psychology from Duke University and subsequently worked as a researcher in brain imaging labs at Duke and Emory Universities. Her current research focuses on machine learning methodology for the prediction of adverse health-related outcomes in trauma care patients, prediction of mass trauma events using social media data, data visualization, and statistical software package development. She also currently works as a consultant at Genentech in South San Francisco.

Rachael V. Phillips
Rachael is a Biostatistics Ph.D. student. She received an MA in Biostatistics in May 2018 from UC Berkeley. She graduated with Cum Laude honors from Texas Tech University in 2015, receiving a BS in Biology with a Chemistry minor and a BA in Mathematics with a Spanish minor. Rachael’s current research involves the application of machine learning methods, nonparametric statistical estimation, statistical computing, and causal inference to large biological datasets to solve real-world problems in human health, molecular biology, and meta-analysis. She is also passionate about online mediated education and responsible conduct in research. Rachael actively works with the UC Berkeley Superfund Research Center and the National Cancer Institute Division of Cancer Epidemiology and Genetics.

Prof. Romain Pirracchio
Biography: Prof. Pirracchio is a French M.D., Ph.D., hailing from Paris. He obtained his M.D. in 2003, with a specialization in Anesthesiology and Critical Care Medicine. In 2008, he obtained a Master’s degree in Medical Research Methodology and Biostatistics. He completed his doctoral studies in the Department of Biostatistics and Medical Informatics (DBIM, unité INSERM U-1153) at Hôpital Saint Louis, Paris, France in 2012 under the guidance of Prof. Sylvie Chevret. In 2012-2013, He spent a year as a postdoctoral fellow in Biostatistics in the School of Public Health at the University of California, Berkeley, where he worked under the supervision of Prof. Mark J. van der Laan and Prof. Maya L. Petersen. Back in Paris, he was the director of the surgical and trauma ICU at European Hospital Geroges Pompidou (2013-2015) and a researcher in Biostatistics at the INSERM U-1153 unit. In January 2015, Dr. Pirracchio joined the Department of Anesthesia and Perioperative care at the San Francisco General Hospital & Trauma Center (UCSF) as Associate Professor.
