Dr Usha .K

Assistant Professor

School of Health Sciences

Dr Usha .K did her graduation and post-graduation in the field of Microbiology from Sri Venkateswara University, Tirupati. Her Ph.D., was a collaboration work with Sri Venkateswara university, Tirupati and Sri Venkateswara Institute of medical sciences (SVIMS), Tirupati.
In her doctoral thesis, she revealed for the first time the sero-types that cause scrub typhus fever in Southern part of India and a few sequences were submitted to NCBI-Genbank. She has over 9 years of research experience.
She is a recipient of Early career Scientist (PI) for a project funded by DBT under BioCARE Scientist Scheme at Indian Council of Medical Research – National Institute of Nutrition (ICMR-NIN), Hyderabad (Project Cost: 41.95 Lakhs) and worked on reverse genetics in Blue Tongue Virus and its molecular characterization.
Currently she is a recipient of Principal Investigator as Young scientist for a project funded by Department of Health Research through Jawaharlal Institute of Postgraduate Medical Education and Research (JIPMER), Pondicherry (Project Cost: 51.90 Lakhs) to carry out molecular objectives on Mycobacterium tuberculosis and Non Mycobacterium Tuberculosis.
Her specialization in the field of Infectious disease, molecular biology, antibiotic resistance mechanism, molecular virology – reverse genetics and immune evasion made her to publish her findings in reputed journals. She participated in many conferences and seminars and presented her work.
