The Weissleder lab is interested in the development of novel in vivo imaging methods for studying complex human diseases such as cancer and infectious diseases. The lab is also involved in translating these discoveries into the development of new diagnostic devices and drugs.

Current research in the Weissleder lab is focused on developing better detection methods for specific cells (e.g. circulating cancer cells, immune cells), cell-derived microvesicles or, bacteria implicated in human disease. The lab utilizes a variety of techniques including whole body and intravital microscopic imaging, novel chemical approaches that perturb specific systems or biological pathways, and innovative sensing strategies that include nanotechnology and microfluidic methods. The lab uses these techniques to: a) obtain quantitative and systems-wide global measurements, b) perform dynamic serial measurements, and c) integrate multiple and various data sets into models. Increasingly, the lab has been focused on reconciling the gap that exists between imaging and traditional cell biology research by developing techniques that are powerful enough to image cellular processes in an in vivo setting. Thus far, the lab’s work on nanomaterials and on novel miniaturized nuclear magnetic resonance (μNMR) chips have led to advanced clinical trials. Single cell analysis systems have also been developed for rapid and accurate diagnosis and monitoring of drug therapy. Whilst the research is primarily basic in nature, much of it has a strong translational focus, with in vivo imaging playing a major role.
