About me:

My scientific interests include any thing and every thing cell death, oxidative stress, lysosomes, nanoparticles and microscopy. I joined the Sarosiek lab to further understand cell death processes and apply this knowledge to either induce cell death (in case of cancer) or inhibit cell death to prevent some of the disease pathologies. My particular interest is to characterize the intrinsic cell death pathway following lysosomal leakage.

I did my grad school at the University of Connecticut (not far from here) where I studied silica induced oxidative stress and cell death in alveolar macrophages. Silica is responsible for the fibrotic lung disease silicosis in workers exposed to silica dust over a long period of time in certain occupational settings. Using live cell imaging, I have tracked the fate of macrophages from silica particle uptake to death. We found that silica can generate reactive oxygen species independent of NADPH oxidases and cause phagolysosomal leakage to induce cell death. Further, there is heterogeneity in cell death, where in, most cells die by apoptosis whereas some by necrosis. Please check out some of the movies from my work:

During summers I like to bike (wouldn’t call myself a cyclist) and kayak. During winters, I enjoy exploring Boston.
