Dr. Arunachalam Ramaiah is a Group Leader (Lead Bioinformatician) at the City of Milwaukee Health Department (MHD). Before joining MHD, he was a Faculty (Senior Scientist) at the Tata Institute for Genetics and Society, Bangalore. Dr. Ramaiah did his postdoctoral research at the Indian Institute of Science, India (IISc), Centers for Disease Control and Prevention, USA (CDC), Stanford University School of Medicine, USA, and the University of California, Irvine/ UCSD, USA. Dr. Ramaiah received his PhD in Bioinformatics jointly from the Manonmaniam Sundaranar University, India, and Abo Akademi University, Finland. He is a recipient of the prestigious ‘ISID New Investigator Award – 2016’ from the International Society for Infectious Diseases (ISID), USA, for his research on T-cell epitope evolution in Mycobacterium tuberculosis strains from India. He is also a recipient of highly competitive APHL-CDC Bioinformatics Postdoctoral Fellowship and Finnish Government Scholarship. In 2022, Dr. Ramaiah has been elected as a Fellow of Royal Society for Public Health and member of Royal Society for Biology, UK. He is a life member of ISID and American Society for Rickettsiology. He is one of the two leads, who have assembled and annotated a ground-breaking new reference genome for the Asian Malaria mosquito Anopheles stephensi and discovered thousands of new gold-standard genes vital for targeting pathogen transmission and immunity. His lab research at MHD, focuses on studying the genomic epidemiology of the SARS-CoV-2, transmission patterns, and studying the RNA viruses (i.e. SARS-CoV-2, Zika virus, Influenza virus) evolution and viral molecular and immunological interactions with their host.
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 more than ten international peer-reviewed journals. Dr. Ramaiah is a member of the International Society for Infectious Diseases, Infectious Diseases Society of America, International Society for Computational Biology, American Society for Microbiology, and American Society for Rickettsiology. He has 12 years of academic experiences gained from leading Institutions in India, Finland and USA and has made academic visits to several countries. He received 25 awards/fellowships/recognitions from both national and International organizations.
