Current Weill Cornell Neurosurgery Residents

Dr. Guadix received his MD in 2023 from Weill Cornell Medical College, where he was a member of Alpha Omega Alpha, the medical student honor society. During his time here at Weill Cornell, Dr. Guadix has gotten to know the neurosurgeons well. He has conducted research in endovascular neurosurgery alongside Dr. Jared Knopman, worked on imaging studies in craniosynostosis with Dr. Caitlin Hoffman, and co-authored a series of academic papers on neurosurgery during Covid and another paper on stereotactic radiosurgery with Dr. Susan Pannullo.

Dr. Guadix took a year off from his medical studies to work under the mentorship of Dr. Mark Souweidane as the Rudin Medical Student Fellow in Pediatric Neuro-oncology, researching enhanced drug delivery systems for pediatric brain tumors. He was awarded the 2022 ChadTough Defeat DIPG Foundation Gamechanger Grant to continue those studies. Dr. Guadix received his bachelor’s degree in cognitive science from the University of Pennsylvania, then completed a yearlong post-baccalaureate pre-medical program at Johns Hopkins University before attending Weill Cornell Medical College.

Dr. Gary Kocharian completed his M.D. at Weill Cornell Medical College after receiving a Bachelor of Arts from Rutgers University Honors College. Dr. Kocharian completed an extra year of research during his time at medical school in the Laboratory of Molecular Neurosurgery, where he helped develop a novel method for profiling changes in gene expression in specific populations of brain cells following vector-mediated viral gene therapy. 

Throughout his time at medical school, Dr. Kocharian worked with Dr. Mark Souweidane on a variety of projects to advance the field of pediatric neurosurgery. He has also served as president of the Weill Cornell Medical College student chapter of the American Association of Neurological Surgeons. An avid musician and athlete, Dr. Kocharian is also fluent in multiple languages.

Lily McLaughlin received her MD in 2024 from Georgetown University School of Medicine, where she was a member of the Gold Humanism Honor Society. We met Lily last summer, when she completed a sub-internship month that showed her to be extremely talented, responsible, and committed to patient care. Prior to medical school, Lily earned a master’s degree in biomedical studies at Drexel University after completing her bachelor’s degree in biology at Villanova. She has co-authored numerous academic research papers, many of them with colleagues from Memorial Sloan Kettering, where she spent three years as a clinical research associate. She has researched and presented on healthcare disparities and participated in mentoring programs and community health initiatives.

Kate Rosen was raised by two teachers and grew up in Salem, Oregon, on a healthy diet of art museums, hiking trips, and Tom Petty. As an undergraduate she attended Santa Clara University, where she studied chemistry, biology, and public health while also working as a volunteer EMT. After graduating, she worked in quality improvement at Stanford Children's Health using clinical informatics and systems-based thinking to improve healthcare. She then received her MD from the Oregon Health & Science University School of Medicine, where she was a member of Alpha Omega Alpha, the national medical student honor society, and of the Gold Humanism Honor Society, which recognizes senior medical students for excellence in compassionate clinical care. Dr. Rosen has been a mentor to students under-represented in medicine and is one of the founders of The Differentialists, a student group formed to build diagnostic reasoning skills. Her research has included studying delayed cerebral ischemia after pituitary macroadenoma resection, and her study of fluid overload in pediatric ICU patients was named Best Abstract by a Trainee at the annual meeting of the American Academy of Pediatrics (AAP). She strives to specialize in neuro-oncology, with a focus on clinical trials and immunotherapy. In her free time Dr. Rosen likes to run marathons and climb mountains.
