How can clinicians better predict who will transition from relapsing to progressive Multiple Sclerosis (MS)? And can we use imaging techniques to diagnose MS more accurately and to select the right treatments for individual patients?

“These are questions people with MS and their doctors struggle with frequently, and so we hope to at least begin to answer them through our research,” says Erin S. Beck, MD, PhD, Assistant Professor of Neurology at the Icahn School of Medicine at Mount Sinai and a neurologist at the Corinne Goldsmith Dickinson Center for Multiple Sclerosis.

Dr. Beck, whose research program explores the intersection of neuroimaging, immunology, and clinical  care, is seeking answers using advanced magnetic resonance imaging (MRI).

“At the heart of our work is a commitment to advancing both science and patient care,” says Dr. Beck. “By deepening our understanding of cortical lesions and the inflammatory processes that drive them, we are helping to shape a more precise and informed future for MS diagnosis, treatment, and care.”

For MS patients, the implications of this work are significant. If these imaging methods are validated, cortical lesion detection could become part of routine MRI protocols within the next several years. This could enable earlier and more accurate diagnosis, improve predictions of how a patient’s disease will unfold, and support more personalized treatment decisions.

Dr. Beck’s lab studies how lesions in the brain and spinal cord form, evolve, and repair in MS and other related diseases. A central focus of her lab’s research is understanding MS lesions in the cortex, the outer layer of the brain, which helps to control most of the brain’s functions. While white matter lesions are well-established markers of MS activity, they explain only part of the disease.

Cortical lesions, though harder to detect with standard imaging, are increasingly recognized as widespread in MS and closely tied to physical disability and cognitive impairment, particularly in progressive forms of the disease. It is unclear whether current MS treatments, which work by stopping new lesions from forming in the rest of the brain, are also effective at stopping cortical lesion formation.

Using state-of-the-art imaging technologies—including more powerful, 7 tesla (T) MRI scanners—Dr. Beck combines MRI with cerebrospinal fluid (CSF) and blood analysis to investigate the formation, repair, and clinical significance of cortical lesions. Her research integrates imaging with measures of inflammation, aiming to discover how immune processes contribute to lesion development and disease progression.

One of her lab’s key contributions is the development of MRI methods to improve cortical lesion detection using widely available 3T MRI scanners. These include IR-SWIET, a novel MRI method specifically optimized for visualizing cortical lesions. The lab is currently testing whether IR-SWIET could be useful for MS diagnosis and for monitoring response to treatment.

Her investigations also extend to patients with Radiologically Isolated Syndrome (RIS)—those whose MRI scans show MS-like lesions despite having no symptoms. Through advanced imaging and CSF studies, she hopes to identify biomarkers that distinguish individuals likely to develop clinical MS from those who will remain symptom-free.

Dr. Beck earned her MD/PhD from Columbia University. Following her neurology residency at New York–Presbyterian/Columbia and a neuroimmunology fellowship at the National Institutes of Health, she joined Mount Sinai’s faculty in 2021. Since then, she has been building her research program at the intersection of neuroimaging, immunology, and clinical MS care.

Dr. Beck’s research has been recognized with awards such as a Clinician Scientist Development Award and a Career Transition Fellowship from the National MS Society. Her findings have been published in leading journals, including Brain Communications, Investigative Radiology, and Human Brain Mapping.

“The question is, how many potential scientists are lost because they have never seen a path forward?” says Anna Bright, a Neuroscience PhD student. “What if, instead of stumbling upon a passion by chance, students had direct access to mentors who could illuminate the possibilities before them?”

When Anna Bright, a Neuroscience PhD student at Mount Sinai’s Graduate School of Biomedical Sciences, was growing up in rural Tennessee, it was not easy to imagine a career in science. Who would be her role model?

“My story is not unique,” says Ms. Bright. “Countless rural students face similar struggles, navigating their education with limited exposure to careers beyond their immediate surroundings. The question is, how many potential scientists are lost because they have never seen a path forward? What if, instead of stumbling upon a passion by chance, students had direct access to mentors who could illuminate the possibilities before them?”

Today, Ms. Bright is leading an outreach effort to implement mentorship initiatives in rural school systems that connect students with alumni who have pursued advanced degrees in science and medicine.

Ms. Bright passionately wrote about her outreach effort in an essay, “Sending Science Down Yonder,” that she submitted recently for the international 2025 Essay Contest sponsored by the Lasker Foundation. In July, she was named one of the four co-winners. Participants were asked to write about a specific innovation in education or training that would help ensure a sustainable, inclusive, and successful future biomedical research workforce.

“Beyond the initial excitement of being named a winner, I mostly felt grateful to have my story shared with a wider audience,” Ms. Bright says. “This is tangible evidence that my personal experience struggling to find how someone of my socioeconomic background could fit into the academic world is something worth telling—and ideally, correcting, for the next generation of scientists.

“Today, well over halfway into my PhD, I still have moments where I doubt I belong in this space. This is a reminder that educational resources need to be extended to students who still encounter barriers to higher education—whether that be financial, cultural, or systemic. I would like to thank my lab members and my mentor, Joel Blanchard, for cultivating such a supportive and creative space for conducting science.”

Ms. Bright is a fourth-year student in the lab of Joel Blanchard, PhD, Associate Professor of Neuroscience, and Cell, Developmental and Regenerative Biology, whose research group engineers 3D models of human brain tissue from stem cells and applies them to understanding and therapeutically targeting risk factors for Alzheimer’s disease (AD), Parkinson’s disease, and other forms of cognitive impairment.

 “We are particularly interested in how glial cells and brain vasculature play a role in neurodegeneration,” she says. “We explore how genetic and environmental factors affect astrocytes, microglia, oligodendrocytes, and the blood-brain barrier in ways that trigger pathology.”

Her thesis project centers around how APOE4, a gene variant and the largest genetic risk factor for AD, affects oligodendrocyte development and myelination. “The primary role of oligodendrocytes in the brain is to produce myelin, the fatty blanket wrapped around axons to promote health and signaling. Myelin degeneration is one of the earliest pathologies in AD, so understanding why it breaks down in this disease could open the door for novel preventative methods.”

In July, she was the first author on a review paper in Nature Cell Biology that included Dr. Blanchard and two researchers affiliated with the Massachusetts Institute of Technology and Harvard University.

“We reviewed literature connecting oligodendrocyte and myelin deficits to AD,” she says. “A wide range of evidence implicates this cell type in AD onset and progression, and we discuss seminal studies establishing oligodendrocyte biology as a key player in AD, proposed underlying mechanisms, emerging techniques in myelin research, and next directions for this field of study.”

Says Dr. Blanchard: “Anna brings a rare combination of creativity, persistence, and a deep sense of purpose to her work. Her research on how APOE4 affects oligodendrocyte development is breaking new ground in our understanding of Alzheimer’s disease, while her passion for mentorship and outreach shows her commitment to shaping the future of science. We’re incredibly proud to see her recognized with this award. It reflects both her scientific contributions and the positive impact she is already having on the next generation.”
