My Ph.D thesis focused mainly on elucidating the role of host factors in host-pathogen interaction. During my graduate studies, I found Wnt5A-mediated actin remodeling to be an essential regulator of autophagy-mediated killing of pathogenic bacteria. My finding on the role of Wnt5A in the containment of bacterial infection opened new avenues for future research, where Wnt5A has been proven to be a critical host factor for the survival of commensal gut bacteria. My graduate studies have resulted in 5 first authored publications.
During my postdoctoral studies I focused mostly on neuroinflammation and the effect of Chromogranin A on neurodegeneration. My Postdoctoral studies already resulted in one first author publication and other publications are in process.
1. Uncovering Wnt5A induced autophagy in host-pathogen interaction.
Wnt5A was known to affect bacterial phagocytosis by altering the cytoskeletal dynamics in macrophages. But whether Wnt5A can be instrumental in containment of bacterial pathogens was unknown. My study revealed the role of Wnt5A in autophagy mediated killing of pathogens like Pseudomonas sp, Streptococcus sp.

2. Discovery of Wnt5A-Arp2 axis mediated actin modulation as a dictator to differentiate between pathogens and non-pathogens
Wnt5A regulates the phosphorylation of Arp2 and successive actin dynamics based on the pathogenic potential of the bacteria. This differentiated actin modulation affects the phagosomal maturation in the macrophages and results in killing of pathogenic bacteria but survival of non-pathogenic ones. This finding paved the way for further research where Wnt5A can be crucial for maintaining commensal in the gut.

3. Wnt5A signaling in phagocytes in the gut helps in the survival of gut commensal
Wnt5A signaling is intrinsically associated with the fate of the bacteria inside the host based on its pathogenic potential. Further, we saw Wnt5A signaling is necessary for the survival of commensal in the gut phagocytes through actin remodeling and maintenance of T-cell homeostasis. This finding has enormous clinical significance in gastrointestinal disorders.

4. Analysis of antibody response in SARS-CoV-2 Infection and Vaccination in India
I was involved in a study to analyze the antibody response from plasma in a large cohort as an aftermath of the SARS-CoV-2 Infection in India.

5. Exploring the function of Chromogranin A and its derived peptides in systemic metabolism
After joining UCSD, I started working with experts in granin biology (Dr. Sushil K. Mahata), inflammation (Dr. Gourisankar Ghosh) and tauopathy mediated neurodegeneration (Dr. Chen). I have contributed significantly to an ongoing work on the role of Chromogranin A in regulating systemic glucose metabolism, where we found that Chromogranin A-depleted mice develop improved insulin sensitivity with age.

6. Exploring the function of Chromogranin A and its derived peptides in tauopathy mediated neurodegeneration
During my postdoctoral tenure I did a comprehensive study on the role of Chromogranin A and derived peptides on tauopathy mediated neurodegeneration in PS19 mouse model. I found that depletion of Chromogranin A is beneficial for attenuating tauopathy mediated neurodegeneration.
