PGY-5 Chief Resident
Sana Siddiqui, MD
I grew up in India and immigrated with my family to the US when I was 12 years old. I attended Cornell University for my undergraduate degree before joining St. George’s University School of Medicine. After medical school, I did my transitional year at the Family Medicine and Preventive Medicine department at Wayne State University in Michigan. My research interests include the role of radiation in palliative care, outcome disparities and gender equity in medicine. In my free time I enjoy puzzles, watching movies, visiting family/friends and spending time with my cat, Nebula.
PGY-2
Daniel Kallini, DO
I grew up on Staten Island, and training here has never felt like a detour — it’s felt like coming back to where I started. After earning my D.O. from Rowan-Virtua School of Osteopathic Medicine in New Jersey, I returned home for my intern year at Richmond University Medical Center, just minutes from where I was raised, and I’m grateful to now be continuing my training in radiation oncology at NewYork-Presbyterian Brooklyn Methodist Hospital.
What drew me to this field is the blend of precision and continuity — the way physics, biology, and patient care come together in a treatment plan, and the trust that builds over the weeks you spend guiding someone through their course of therapy. I’ve had the privilege of contributing to research published in the International Journal of Radiation Oncology, Biology, Physics, including work on PET SUV analysis in head and neck cancer patients receiving photon and proton radiation, and a propensity score-matched study on organ-at-risk outcomes with radiotherapy dose de-escalation in HPV-mediated oropharyngeal cancer. I’ve also contributed to research on nasopharyngeal carcinoma radiation techniques published in Oral Oncology. I’m humbled by the chance to keep building on that work, and especially grateful to be doing it within the very city that shaped me.
Outside the hospital, I’m recently married and spend my downtime around cars, catching NBA games, and hunting down hidden gem food spots around the city.
Christopher Zaki, MD
I grew up in Southern California and earned my bachelor’s degree in Health Promotion and Disease Prevention from the University of Southern California before receiving my medical degree from the University of Arizona College of Medicine – Tucson. After completing a preliminary year in Internal Medicine at Huntington Hospital in Pasadena, California, I joined the Radiation Oncology Residency Program at NewYork-Presbyterian Brooklyn Methodist Hospital.
I was drawn to radiation oncology because it sits at the intersection of advanced imaging, precision medicine, and cancer care. I enjoy the specialty’s blend of technology, multidisciplinary collaboration, and thoughtful treatment planning while having the opportunity to build meaningful relationships with patients throughout their cancer journey.
My academic interests include thoracic, genitourinary, and central nervous system malignancies, as well as advanced oncologic imaging, treatment response assessment, and the application of emerging technologies to optimize radiation treatment planning and improve patient outcomes. I hope to pursue a career that integrates exceptional clinical care with research and innovation to advance the field of radiation oncology.
Outside of medicine, I enjoy strength training, hiking, traveling, sim racing, playing the drum set, building LEGO sets, and spending time with my Samoyed, Bear.
The New York-Presbyterian Brooklyn Methodist Hospital Radiation Oncology Residency Program accepts residency applications through ERAS, we participate on the NRMP.
