Joshua Slone 

MS, Applied Economics, Johns Hopkins University
BA, Modern Middle Eastern Studies, University of Pennsylvania

Joshua is originally from Tampa, Florida. His path to biostatistics began in 2016 when he joined an expert witness group quantifying healthcare fraud at the US Department of Justice (DOJ). He worked on matters ranging from over-prescribing to unnecessary hospice services. For such cases, he designed statistical samples and analyzes/merges claims data, electronic health records (EHRs), and internal company sources. Joshua is eager to transition from retrospectively analyzing the worst of healthcare to building predictive models to improve human health.   


Jared Strauch   

BS, Biology, University of Wisconsin-Madison

Jared is originally from Minnesota. After graduating from Wisconsin, Jared spent a few years studying adherens junctions in C. elegans and then joined the lab management team at Exact Sciences, where he became deeply interested in the statistical methods that led to the development of Cologuard and other cancer screening technologies. His main interest is in statistical genetics, with an emphasis on biomarker discovery. Outside of work, he enjoys playing volleyball, board games, and hiking with my dog, Cooper. 


Megan Taylor  

BPH, Public Health, University of Kentucky (mathematics minor)

During college, Megan worked for the Kentucky Violent Death Reporting System as a data abstractor, constructing case narratives for homicides, suicides, and undetermined deaths. She is passionate about data-driven public health improvements and mental health, which she would love to incorporate into her work. In her personal life, she is an avid board game fan, reader, and geocacher.   


Julia Whitman

MS, Epidemiology, Imperial College London
MA, University of St. Andrews   

Julia's career in public health research started at Imperial College London, where she focused on chronic disease and cancer epidemiology. During her studies, she also edited regional HIV prevention proposals in Eastern Europe and the Balkans for the United Nations Development Program. She has since worked an intern at the Fred Hutchinson Cancer Center, clinical trials coordinator in the gastrointestinal oncology department at the University of California, San Francisco (UCSF), and data manager and clinical research analyst for UCSF’s Center for Neuroendocrine Tumors, where she enjoyed collaborating with an interdisciplinary team to answer questions in areas ranging from genomic medicine and survival analysis to in-clinic quality improvement.   


Bailu (Lucy) Yan

MS, Applied Statistics and Data Analytics, Southern Methodist University
BS, Finance, Central University of Finance and Economics (Beijing)

Lucy most recently worked as a research assistant in the Department of Chemistry at Vanderbilt University, focusing on data-driven methodologies for biomolecular discovery. Before coming to Nashville, she worked in industry as a data analyst for two years, where she developed competency in both statistical research and real-world applications. Knowing the huge potential of statistical solutions in biomedicine and biological research, she's enthusiastic about embarking on an academic path toward solving open challenges in human health and diseases treatments.


Lydia Yao

BS, Data Science and Mathematical Statistics, Purdue University   

While studying data science, Lydia developed an interest in statistical methods and modeling within health and medicine. She grew up in Indiana and enjoys playing piano, guitar, and clarinet. Competitive swimming has been a big part of her life, and she still occasionally swims for exercise. She enjoys solving sudoku puzzles and cooking different cuisines.   


Elisa Yazdani

BA, Chemistry and Psychology, Washington & Jefferson College (mathematics minor) 

Elisa is originally from North Carolina. Over the course of three internships - one at Vanderbilt and two at Duke - she worked on a variety of projects, studying neurodevelopment in animals, cognitive diseases, electrophysiology, and the impacts of drugs. “Paternal THC Exposure in Rats Causes Long-Lasting Neurobehavioral Effects in the Offspring,” a paper on one of her projects at Duke, was published in the Neurotoxicology & Teratology Journal. Her interests include pharmacokinetics, electrophysiology, cognitive disorders, and clinical trials. In her free time, she enjoys watching classic movies, sports, working out, and cooking.

Spotlight on Vanderbilt Biostatistics: Pei-Ying (Emily) Lin

This week’s spotlight series features Dr. Pei-Ying (Emily) Lin, a visiting scholar from the National Taiwan University Hospital in Taipei City, Taiwan. She is a specialist in pulmonary and critical care medicine, focusing on thoracic oncology. Her research interests include translational cancer research, data science, and precision medicine in cancer treatment.

What have been the major findings so far in your research? What could be the impact?

My major research field is lung cancer, the leading cause of cancer-related death worldwide. The driving force of lung cancer oncogenesis varies over different subtypes. My research topics primarily focus on dissecting mechanisms in order to develop therapeutics for current unmet needs. For example, CNS penetration, drug resistance, and poor response to immune checkpoint blockades in driver mutation positive cases.

What lessons have you learned throughout your career? How have these lessons drawn you to Vanderbilt?

After years of training in many topics, from clinical medicine to translational cancer research, I am a strong proponent for the importance of data science in this new era of medicine. High-dimensional data - whether structural or non-structural, genomics, proteomics, radiomics, or medical records - are becoming the core of modern medical research. Data integration and elaboration based on solidified analytical and verification processes and clinical experiences are now common practice. These are the reasons I am here at Vanderbilt – to further develop my understanding of data science and precision medicine.

What is your philosophy about research?

My philosophy about research is to discover the undiscovered etiology and/or mechanism of an unsolved problem, which can be a biological phenomenon or a disease, and to be honest and respectful to the data and findings. One should always integrate and interpret data properly, so that the research findings can make good to what inspires us to initiate the research project in the first place.

What are your thoughts on the debate between modern data science and traditional statistical practices?

The increasing importance of data science in the biomedical field is clear. Its application is most successful with strong teamwork and collaboration between data scientists and other researchers. Working to incorporate new techniques will only improve health and research outcomes.

Tell us about your life outside of Vanderbilt.

While my professional life keeps me very busy, I try to maintain my hobbies in music and arts. I enjoy listening to music and exercising to stay healthy and balance my work and life.
