Current Research

This section aims to develop new methods and tools applied to the study of biomolecules of interest, with a focus on designing new compounds for targeting cell surface receptors. We are particularly interested in the preparation of conjugates that consist of synthetic molecules and proteins. Towards this end, we develop new methods of protein preparation and conjugation, undertake medicinal chemistry campaigns, and perform pharmacological assays. These approaches focus on the pharmacology of G protein-coupled receptors, a family of proteins which constitute the target of over a quarter of approved therapeutics, with a specific emphasis on receptors relevant for the treatment of osteoporosis, diabetes, and inflammation. Findings from these studies will guide the rational design of therapeutics with improved properties.
