Dr. Theodosopoulos specializes in treating skull base lesions, particularly acoustic neuromas and meningiomas, with a focus on minimally invasive endoscopic techniques. His research explores molecular classification of brain tumors, surgical outcomes, and epigenetic evolution in glioblastomas. He has pioneered new surgical approaches and led major clinical trials on acoustic neuromas.

Recent publications highlight his work on DNA methylation groups in meningiomas, postoperative complications, and molecular divergence in brain metastases. Awards include the Dean’s Award for Distinguished Research at Stanford and multiple visiting lectureships at institutions like Baylor and UCSF. He actively contributes to neurosurgical education through courses and committees.
