Who We are

We are a basic and translational research laboratory at the Emory University School of Medicine. Emory University is a private, not-for-profit institution located in the Historic Druid Hills neighborhood of Atlanta, Georgia. Emory University is a research intensive university according to the Carnegie Classification of Institutions of Higher Education (read more HERE). Basic research is focused on gaining a molecular-level understanding of how the world works. For our lab, that includes understanding the physics and engineering behind magnetic resonance imaging (MRI) scanners and determining how our brain is affected by disease. Translational research takes our findings from basic research and attempts to 'translate' them into clinics and hospitals.

Cancerous Brain Tumors

The Centers for Disease Control and Prevention estimate over 22,000 new brain cancer diagnoses are made in the U.S. each year. Gliomas are a type of brain cancer that account for nearly 75% of all cancerous brain tumors. The most aggressive form, called glioblastoma, has a five-year survival rate of less than 6% (Central Brain Tumor Registry of the US). One of the hallmarks of all cancers is an increase in inflammatory markers – small molecules released by the body in response to illness or injury. We observed that systemic inflammation can lead to changes in brain chemistry, particularly increases in glutamate (Read more HERE). Our goal is to identify new inflammation-related biomarkers, or indicators, that can be used to monitor brain tumors and their treatment.  We are developing new non-invasive tools for MRI scanners to monitor tumor growth and response to treatment, with the end goal of increasing survival rates for brain tumor patients.

Brain Thermometers

Brain temperature is important for healthy brain activity and recovery after brain injury. Currently, the only clinical method that exists to measure brain temperature is an invasive, surgically-implanted probe inserted into the brain through the skull and is impractical for routine use in healthy humans. We are developing new, non-invasive methods for measuring brain temperature using MRI scanners. These tools are being tested in both healthy human volunteers and in patients after head injury or disease such as stroke or concussion.

New Technology for MRI scanners

MRI scanners are commonly used in hospitals and outpatient clinics. The benefits of MRI and a similar technique, MRS, are that these methods are non-invasive (when used without contrast agents), provide high-resolution images of the brain and body, and can be repeated to look at changes over time. However, there is still room for improvement. Many MRI techniques are slow and patients have to lie in the scanner for long periods of time. Motion often distorts MRI images and can be difficult to correct. We are working to develop new methods for acquiring and analyzing data from MRI scanners.

Where we Publish

Most of our work is published in peer-reviewed scientific journals.  While many scientific journals require a paid subscription, some provide open-access content meaning that the papers are free and available for anyone to view online. Publications resulting from research funded by the US government are publicly available. One of the largest repositories of publicly available manuscripts is the National Library of Medicine's PubMed Central database, where all publications resulting from National Institutes of Health (NIH) funding are archived.

You can read our publications HERE. If you don't have a subscription to the journal, you can use the PubMed link to view them for free or access PubMed Central directly HERE.

how we fund our research

Funding for scientific research comes from many sources. Universities and institutions provide some funding for research, particularly for new studies. Most of the funding for our research comes from US government agencies including the National Institutes of Health, National Science Foundation, Department of Defense, etc. We also apply for funding from private foundations such as the American Cancer Society. Databases for all government-funded research, including a description of the research and amount of funding, are publicly available. You can learn more about government-funded research HERE, under Public Resources.

Curious about volunteering?

This video details the process of being in a 7T MRI in the Health Science Research Building II. Featuring Eva as a volunteer, our MRI tech, and Dr. Candace Fleischer’s voice-over, the specifics of what a volunteer will experience in a 7T MRI study is mentioned along with the corresponding visuals.
