Esther Bhaskar is a prominent researcher in the field of infectious diseases, with a particular focus on the intersection of HIV treatment and public health. Her recent work has significantly contributed to understanding the metabolic changes associated with antiretroviral therapy in specific populations, particularly among Black women living with HIV.

In 2024, she published a pivotal study in the journal HIV Medicine, which explored the weight and metabolic changes experienced by participants in a phase IIIb clinical trial. This research is crucial for informing treatment protocols and improving health outcomes in marginalized communities.

Additionally, Bhaskar's research extends to the epidemiology of viral infections, as evidenced by her 2022 publication in Open Forum Infectious Diseases. This study compared the rates of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infections during the Delta and Omicron waves in Johannesburg, South Africa, providing valuable insights into the dynamics of viral transmission and public health responses.

Through her scholarly contributions, Esther Bhaskar continues to advance the understanding of infectious diseases and their impact on diverse populations, making her a vital voice in contemporary public health discourse.
