Ramaiah serves as Director of Bioinformatics, Project Director, and Principal Investigator for the CDC-funded Pathogen Genomics Center of Excellence (PGCoE) at the Georgia Public Health Laboratory (GPHL). He received his PhD jointly from Manonmaniam Sundaranar University and Åbo Akademi University. Following his doctoral research, Ramaiah completed multiple postdoctoral research appointments at the Indian Institute of Science, the US Centers for Disease Control and Prevention (CDC), and the Stanford University School of Medicine. He brings over 18 years of experience spanning academic institutions and local, state and federal public health laboratories in the United States and internationally. His expertise addresses emerging public health challenges across viral, bacterial, immunological, human, and disease vector–related research.
Ramaiah has authored 52 peer-reviewed publications, including articles in Nature and Cell group journals. He has received several awards and recognitions, most notably the highly competitive International Society for Infectious Diseases (ISID) New Investigator Award in 2016, recognizing his scientific contributions to Mycobacterium tuberculosis genomics and bioinformatics. Ramaiah began his US public health laboratory career at the CDC as an APHL-CDC Bioinformatics Postdoctoral Fellow, contributing to vector-borne pathogen genomics and advancing bioinformatics within the Rickettsial Zoonoses Branch. He later served as Lead Bioinformatics Scientist at the Milwaukee Public Health Laboratory (MPHL), leading SARS-CoV-2 genomic surveillance and managing multiple CDC-funded projects. Since 2019, he has held leadership roles at the Tata Institute for Genetics and Society and MPHL, served as visiting faculty at UC San Diego and UC Irvine, and currently holds senior leadership at GPHL.
As the Founding Director of Bioinformatics at GPHL, Ramaiah has been instrumental in advancing bioinformatics analytics and data modernization. Under his leadership, the division supports near–real-time genomic surveillance for multiple CDC programs, including the Emerging Infections Program (EIP), Antimicrobial Resistance Laboratory Network (AR Lab Network), National Wastewater Surveillance System (NWSS), and PGCoE. His work provides critical support across the Georgia Department of Public Health (GDPH), including Epidemiology and Information Technology, and has significantly strengthened the state’s capacity to recognize and respond to emerging and re-emerging infectious disease threats. Notably, Ramaiah leads multidisciplinary teams of staff and APHL fellows to develop and implement whole-genome sequencing (WGS) assays for Respiratory Syncytial Virus (RSV) and influenza viruses, the first such implementation at GPHL. He has also spearheaded automation of end-to-end data analytics workflows, from raw sequencing data transfer to analysis and reporting within an AWS cloud environment. These efforts serve as a model for advancing public health genomics in state and local laboratories.
As Project Director and Principal Investigator of Georgia-PGCoE, Ramaiah works closely with laboratory and scientific teams across GDPH and oversees budgets, work plans, and contracts with five Georgia-based universities and one Texas-based university. Since 2022, these partnerships have fostered innovation and built capacity in pathogen genomics, molecular epidemiology, and bioinformatics, enabling faster and more effective responses to emerging infectious diseases. To date, Ramaiah has secured approximately $17 million through the PGCoE program, along with several million dollars through the Epidemiology and Laboratory Capacity (ELC)–Advanced Molecular Detection (AMD) program. Ramaiah also serves as an investigator for multiple CDC-funded programs, including ELC, EIP, and NWSS, and as Business Officer for Georgia-PGCoE, leading administrative coordination with CDC and academic partners. He plays a critical role in translating and implementing both wet-lab and bioinformatics workflows for routine pathogen genomic surveillance, outbreak investigations, and genomic epidemiology. In addition, Ramaiah serves as the AMD Workforce Development Leader for Georgia, coordinating seminar series, hands-on workshops, and online training programs across the Southeast Region. Through collaborations with public health, academic, and industry partners, he has developed curricula in genomic and molecular epidemiology covering next-generation sequencing, antimicrobial resistance, pathogen genomics, and wastewater surveillance. He has ensured training materials are publicly accessible, benefiting laboratories nationwide.
Ramaiah is deeply committed to mentorship, supporting staff, fellows and interns from APHL, CDC and PGCoE in their professional development, conference presentations and peer-reviewed publications. Drawing on his expertise, he has contributed to APHL initiatives including the Molecular On-call Network, Genomic Epidemiology programs, the PGCoE Network, and the AMD Workforce Development program, and he serves as a Bioinformatics Training Leader in Georgia for the Southeast region.
