Rahul Mahajan, MD, PhD, is a prominent resident physician and researcher specializing in neurology and neurocritical care. Currently affiliated with the Partners Neurology program at Massachusetts General Hospital and Brigham https://drrahulmahajan.com/ and Women’s Hospital, his work bridges the gap between fundamental biophysics and clinical neurological treatment. His extensive academic background includes an MD and a PhD from the Virginia Commonwealth University School of Medicine, where he focused on the intricate mechanisms of ion channels.

Dr. Mahajan’s research is deeply rooted in electrophysiology and biophysics. He has contributed significantly to the understanding of inwardly rectifying K+ (Kir) channels, which play a vital role in maintaining the resting membrane potential and regulating cellular excitability. His publications, which total over 32 scholarly works, often explore the regulation of these channels by phosphoinositides and G proteins.

Key areas of his published research include:

• GPCR Signaling: Decoding signaling mechanisms to understand the action of antipsychotic drugs.
• Channelopathies: Investigating how plasma membrane phosphoinositides impact ion channel function.
• Cardiac and Brain Health: Studying atrial GIRK channels and their role in cardiac rhythm.
• Ischemic Stroke: Recent work includes advances in IV thrombolysis and using AI to stratify risk for atrial fibrillation after a stroke.

Professionally, Dr. Mahajan is recognized as a board-certified neurologist (as of 2024). His clinical practice focuses on stroke and neurocritical care. He completed a specialized Neurocritical Care Fellowship through the Mass General Brigham program in 2021. His multilingual capabilities in Hindi, Punjabi, and Spanish allow him to provide personalized care to a diverse patient population Mass General Hospital.
