Martin Angst, MD
Professor of Anesthesia

The Angst Laboratory’s transformative research efforts focus on immune health in the context of surgery and trauma. In a broader sense, their work is pertinent to clinical conditions that are governed by an acute inflammatory response. The aim of studying immunity in patients suffering from acute inflammatory conditions such as surgery is to identify immune phenotypes that will predict clinical outcomes, discover maladaptive mechanisms that result in adverse outcomes, and devise immune-modulatory strategies that will improve outcomes. Mass cytometry (CyTOF), proteomics, and functional ex-vivo immune assays are the major molecular tools used for the systems-based functional exploration of the circulating immune system.

Assistant Professor of Psychiatry

Amit Etkin is a human systems neuroscientist and psychiatrist. His interest is in using advanced functional neuroimaging tools to define causal neural circuit pathways in the brain in health and disease. To do this, he combines external perturbation of brain circuitry using transcranial magnetic stimulation (TMS) while imaging the consequences with concurrent fMRI or EEG. This allows them to define what the causal consequences are in the brain of inducing activation in any particular region in accessible cortical regions. He hopes to apply these methods to stroke patients in the acute phase and recovery in order to define systems-level plasticity and opportunities for novel neural circuit-directed interventions.

Michelle L. James, PhD
Instructor, Radiology and Neurology & Neurological Sciences

My research is focused on developing and evaluating molecular imaging agents for visualizing neurological diseases in living subjects.

In particular, I am interested in imaging neuroinflammation, microglial activation, neurodegeneration, cognitive decline, and neurogenesis using positron emission tomography (PET). Non-invasive PET imaging of these biochemical processes in living, intact, subjects may lead to an enhanced understanding of a range of brain disorders (including Alzheimer’s disease, multiple sclerosis, and brain injury), ultimately generating effective diagnostic techniques and treatment strategies.

My Ph.D. was focused on the design and development of novel PET radioligands for imaging the translocator protein (18kDa) (TSPO). Since TSPO expression reflects microglial activation and neuroinflammation, radioligands for this protein may act as valuable tools for detecting regions of active brain disease before clinical signs manifest. These radioligands may also be used to track disease progression and monitor response to novel therapeutics.
