Bio

The focus of my research is on the systems biology of aging, taking an integrative view of a biological process that disturbs a broad range of cellular and physiological functions in a complex and global fashion. We explore concepts from engineering (complex systems, robustness, control theory) to decipher the biology of aging at the intersection of experimental, computational, and theoretical biology. We have established an aging model for post-mitotic cells through “Energy Restriction in Quiescence” (ERiQ), resembling stress responses and transcriptional regulation seen in many aging tissues.

We have suggested that aging is a robustness tradeoff of complex evolutionary systems, which provides evolutionary theories of aging with an engineering-oriented view. We use feedback loop motifs from control theory in conjunction with rule-based descriptors to assemble generic whole cell models predicting the progression of aging. The approach demonstrates the interaction of ongoing damage, stress response, and adaptive-regulatory mechanisms. Such models can be executed rapidly and repeatedly to study the effect of molecular mechanisms on the aging phenotype.

In 2007, I co-organized a first workshop on the Systems Biology of Aging at the Santa Fe Institute, NM, entitled "Complexities of Aging in Biological Systems." Subsequent 2008 and 2009 meetings promoting systems approaches in aging included seminars held at ASU and NIH-NIA, under the title of "Systems Biology in Human Aging," which was continued as SBHA-2010 in Philadelphia, PA.

My teaching interests are in Biosimulation, Principles of Systems Analysis, Biostatistics and Bioimaging.
