Using the yeast Saccharomyces cerevisiae as a model organism, we are interested in understanding and controlling aging and replicative lifespan at the single-cell level. We apply quantitative systems biology methods and a high-throughput microfluidic platform to the study of cellular aging. Our immediate and long-term goals are to: (i) uncover deterministic and stochastic factors affecting replicative lifespan and survival distributions, (ii) elucidate how gene expression levels and genetic noise are altered by the aging process, (iii) identify the components of the master regulatory network governing aging, (iv) characterize the connectivity among the network components including feedback loops, (v) discover chemical compounds that are able to modulate basic aging process and extend lifespan.

Compound in Testing: NIH Interventions Testing Program (ITP) website is updated with the 2019 cohort of compounds-in-testing, listing the AcarLab-discovered/proposed chemical compound Mycophenolic Acid (MPA). ITP is a multi-institutional study investigating treatments with the potential to extend lifespan, and delay disease & dysfunction in mice.
