Our Research Interests

Our laboratory investigates the interplay between the host genetics, microbiome, and environmental exposures in the development of complex diseases, including Parkinson’s disease, inflammatory bowel disease (IBD), cardiovascular disease, type 2 diabetes, and craniosynostosis. We combine genetic mapping in admixed and isolated populations with systems biology approaches and experimental studies to gain a deeper understanding of the biological pathways involved in disease pathogenesis and risk transmission. A detailed description of current projects can be found under the Research tab.

The Peter Lab had a very successful 2023 that we look back on fondly. The MECONIUM Study continues to collect longitudinal samples, with the oldest participants turning 8 this year! In April 2023, we hosted the first international LRRK2 Symposium at the Icahn School of Medicine at Mount Sinai, bringing together leading investigators in the field of LRRK2 research and the foremost IBD researchers at Mount Sinai. The MELODY Trial met its recruitment goal and produced it’s first publication evaluating dietary intake of pregnant women with and without IBD in the journal Nutrients’ special issue: Dietary Patterns and Nutrient Intake in Pregnant Women. And our own lab member, Manasi Agrawal, MD, MS, launched her first study as a Principal Investigator which is now recruiting: The PLANET Study.

And on a personal level, we are pleased to have our high school summer volunteers getting into college, our college volunteers awarded grants and team members moving on new phases of life as grandparents and fiancés.

Here’s to an equally successful 2024!
