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.

Alexandra Giantini Larsen is a graduate of Harvard Medical School, where she was vice president of the AANS medical student chapter and co-president of the Harvard Medical School chapter of the Association of Women Surgeons. She earned her bachelor’s degree with honors in Molecular and Cellular Biology at Johns Hopkins University.

Dr. Larsen spent a year as a Howard Hughes Medical Institute Medical Research Fellow in the laboratory of Dr. E. Antonio Chiocca, Chair of Neurosurgery at Brigham and Women's Hospital in Boston, where her research was focused on viral therapies for glioblastoma. She also has spent time as a researcher in the Vascular Biology Program at Boston Children's Hospital with Dr. Edward Smith and in the Brain Tumor Stem Cell Laboratory at Johns Hopkins Hospital with Dr. Alfredo Quinones-Hinojosa. She was an observer in our own department during her college years, when we recognized her emerging talents, and we are delighted to have her join us for her residency.

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.

Dr. Nalini Tata received her medical degree from Northwestern University’s Feinberg School of Medicine, where she was elected to the Alpha Omega Alpha medical student honor society, with a concurrent Master of Public Policy (MPP) degree from the Harvard Kennedy School of Government. Dr. Tata received her undergraduate degree in neurobiology from Brown University, then earned a Master of Philosophy degree from the University of Cambridge in England before enrolling in medical school. As a student researcher with Dr. Rees Cosgrove at Brigham and Women’s Hospital, she helped study asleep DBS practices and outcomes. She has also written about ethics and philosophy of neurosurgical practice during and beyond the time of the Covid-19 pandemic with Dr. Nader Dahdaleh at Northwestern Memorial Hospital.
