Spotlight on Chris Lindsell

Professor Chris Lindsell, who leads the ACTIV-6 Data Coordinating Center, was featured in the February 11 issue of the ACTIV-6 Site Newsletter, which is published twice a month by Duke Clinical Research Institute. The interview is republished here with permission.


What is your role on ACTIV-6? I am privileged to lead the Data Coordinating Center. Our team has developed an innovative way of running studies by using the research record like the medical record. The data we collect includes a mix of the information we need to find out what medicines help patients feel better faster, and all of the data needed for real time study information sharing and communications. The partnership with DCRI has allowed us to create a fully integrated system that will continue to get better as we learn from this new way of doing studies. 

 

What activities or hobbies do you enjoy outside of work? I used to play rugby, but then I blew out my knees. Then I used to sail, but there isn’t much water in Nashville. I took up gardening but my brown thumb left me with little hope. For a while, I was a craft beer brewer and home vintner, which also had bad side effects. Pandemic isolation gave me a whole new lease on life and I got to teach myself the guitar while smoking bacon, chicken, salmon, turkey, brisket, cheese, bread, and even vegetables. This year I plan to master the art of pastry (or patience, or both).

 

Why do you think ACTIV-6 is important? If there is a safe medicine already available that could help people feel better faster from Covid-19, I want to know that, I think that’s important.

 

What drives and motivates you about working on the ACTIV-6 study? The challenge of finding a way to do research in totally different ways and solving the problem of what medicines help people feel better faster drives me. The passion, dedication, and excellence of the teams that are leading this research motivate me.

Yan Yan, Distinguished Teaching Assistant

New Biostatistics students in Nashville

The fall semester has begun, and these ten brilliant, engaging individuals are the newest students in our graduate program. Here are a few details about their studies, careers, and interests. We are very much looking forward to learning and working with them!

 

Nate Dowd 

BS, Biology, Colby College (statistics minor) 

After graduating from Colby, Nate worked as a data analyst intern at GlaxoSmithKline, where he developed statistical models for analyzing consumer healthcare data. Some of his interests outside of the classroom include tennis, fantasy sports, traveling, and cooking.     

 

Yeji Ko 

BS, Statistics, University of Michigan 

Yeji (rhymes with "veggie") grew up in Seoul, Korea. In Ann Arbor, she became interested in biostatistics and learned how to survive in cold weather. In her spare time, she loves traveling, exploring new places, and having great conversations over delicious meals.     

 

Lan Shi 

MS, Applied Statistics, University of Michigan
BS, Statistical Science, Chinese University of Hong Kong

Lan's research interest lies mainly in the application of machine learning to biomedical imaging data and wearable health device data analysis. She enjoys travel, hiking, music and, during the pandemic, easy dance workouts at home.

 

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.
