Dr. Arunachalam Ramaiah
Director
Pathogen Genomics Center of Excellence &
​Bioinformatics

Dr. Arunachalam Ramaiah is a Director of Pathogen Genomics Center of Excellence at Georgia Department of Public Health, United States. He has received his PhD jointly from MS University, India and Abo Akademi University, Finland, where he studied influenza A/H1N1 virus. After his doctoral research, Dr. Arun had multiple postdoctoral research experiences at the Indian Institute of Science (IISc), Bangalore (bacterial genomics), U.S. Centers for Disease Control and Prevention (CDC), Atlanta (tick metagenomics and vector-borne pathogens), and the Stanford University School of Medicine, Stanford (food allergy and human TCR diversity). Then he served as Senior Scientist (Faculty) at Tata Institute of Genetics and Society (TIGS) at Institute for Stem Cell Science and Regenerative Medicine (inStem), Bangalore and led a group of scientists to investigate SARS-CoV-2 and many other RNA viruses. During his tenure at TIGS, he spent two years as the Visiting Scientist at University of California (UC), San Diego and also served as the Assistant Project Scientist at the UC, Irvine. Most recently Dr. Arun was a Group Leader (Bioinformatics) at the Milwaukee Public Health Laboratory, Wisconsin.
Dr. Arun is a subject matter expert in the field of Bioinformatics, Pathogen Genomics, Host-Pathogen Interactions, and Genomics Epidemiology. He has an outstanding academic career partnering with researchers across the globe, CDC and WHO. Dr. Arun’s work played a crucial role in implementation of genomics in interpreting emerging public health challenges in the US and globally, which were published in Cell and Nature groups, and other reputed journals in the field. He received several awards and pinnacle of these are prestigious ISID-New Investigator Award, DBT-Young Scientist Award, APHL-CDC Bioinformatics Postdoctoral Fellowship, and Centre for International Mobility Scholarship. He is an elected Fellow of the UK Royal Society of Public Health and serves as a member of many national and international societies. Dr. Ramaiah is an Academic Editor in PLoS ONE, Review Editor in Frontiers in Microbiology, Frontiers in Genetics and Frontiers in Ecology and Evolution journals, and also a reviewer for dozens of international peer-reviewed journals.
