Hard working, innovative and motivated individual with over seven years of research experience in basic life sciences involving experimentation, troubleshooting, planning and developing research projects. Proficient in reading, writing and scientific analysis of academic publications with excellent written and verbal skills. Currently seeking peer review experience pertaining to reviewing original research publications and/or reviews focusing on aging, insulin signaling, TOR (Target of rapamycin) pathway, stress response pathways, pathways/genes involved in maintenance of protein homeostasis and stem cell biology especially with respect to age associated changes in stem cell and diseases.

Dissertation involved studying the role of homeodomain protein kinase -1(hpk-1) in C. elegans aging and stress response. hpk-1 encodes a dual specificity serine threonine kinase that has broad functions in cellular growth, proliferation and mediating stress signals in mammals. However, little is known about its molecular functions and mechanisms in C. elegans. An epistasis study previously done in the lab, identified hpk-1 as one of the genes which acts in hsf-1 pathway to influence aging. The overall goal of the project was  to understand the biology of how this gene acts to influence worm aging and heat shock response. My thesis work elucidated novel role for hpk-1 in aging via maintenance of protein homeostasis through two distinct mechansims. First, HPK-1 positively modulates HSF-1 (Heat Shock Transcription Factor 1) to promote gene expression of chaperones that mitigate toxic effects of proteotoxic stress and second, HPK-1 activity is essential downstream of TORC1 (Target of Rapamycin Complex 1) inhibition to promote autophagy that has also been linked with clearance of protein aggregates. Using extensive genetic and molecular experiments, I was able to show essential roles for hpk-1 in normal as well as TORC1 mediated longevity.
