Meet the NLM Investigators: Dr. Zhiyong Lu is Teaching Computers to Think Like Scientists
Let’s meet Zhiyong Lu, PhD, a Senior Investigator for our National Center for Biotechnology Information (NCBI) Computational Biology Branch and member of the NLM Intramural Research Program. He is leading a team of research scientists to harness the power of machine learning and artificial intelligence (ML/AI) to advance the ways our products and services work—advancements … Continue reading Meet the NLM Investigators: Dr. Zhiyong Lu is Teaching Computers to Think Like Scientists
A Rare Public Health Challenge
Most public health challenges may seem obvious. The COVID-19 pandemic, for example, swept the globe and in some way touched the lives of everyone. But not all public health challenges are as readily apparent.
NCBI-NIAID Beyond Phylogenies Codeathon was a success!
SARS-CoV-2 genomic data is critical for monitoring the viral spread and evolution of the COVID-19 pandemic, identifying newly emerging variants, and developing and evaluating the countermeasures. As of September 2022, over 13 million SARS-CoV-2 genomes have been sequenced across the world, making it the most sequenced pathogen ever. A cornerstone of genomic analysis is building … Continue reading NCBI-NIAID Beyond Phylogenies Codeathon was a success!
