Research Abstract:

Our group focuses on aging and mental health, two increasingly pressing quality of life issues. Core competencies: molecular biology and programming.

Current projects:

1. 10X Lifespan: Manipulating the leading aging pathway, insulin/mTOR, causes a 0.1X lifespan extension. It is unclear whether this extension adds to quality years. We aim for a 10X extension of healthy living. This project is discipline agnostic, meaning we are considering theoretical, organismal, societal, and environmental approach.

2. A Molecular Diagnostic for Mood: Mental health professionals lack a rigorous diagnostic tool like physicians have with glucose, cholesterol, and cell number measurements for Diabetes, Cardiovascular disease, and Cancer, respectively. We aim to change that.

3. Disruptive Innovation of Blockbuster Drugs: Blockbuster drugs like the SSRIs/Lithium (Depression/Bipolar Disorder), Statins (CVD), Bisphosphonates (bone-involving diseases like Osteoporosis), Biguanides (Diabetes) are incumbent medicines that often have numerous reasons not to use them: they can have considerable side effects, simply not work well, and be expensive. We employ multiple technologies: CRISPR and other genetics, metabolic, computational systems approaches to identify targets for high-impact areas such as Osteoporosis and Depression/Bipolar Disorder. We have identified new targets for the Bisphosphonates and Lithium and are elucidating their biology.
