  • Sandra Zaky

    Sandra Zaky

    Clinical Associate Professor, Radiation Oncology - Radiation Therapy

    BioDr. Zaky is a board certified Radiation Oncologist. She received a Bachelor’s of Science in Biomedical/Electrical Engineering at Marquette University. She worked in research and development as an Engineer, and eventually received a Masters of Science in Immunology from Albany Medical College. Her research thesis focused on a novel therapy to treat hormone-receptor positive breast cancer. She continued to study breast cancer with her research during her Radiation Oncology residency; she integrated her research in the laboratory with her clinical research in triple-negative breast cancer. Since completing residency, she has worked as a general radiation oncologist, and her special interests include breast cancer, skin cancer, CNS tumors and stereotactic radiotherapy.

    Current Research and Scholarly InterestsFree-breathing gated CBCT acquisition on C-arm linear accelerator (LINAC) is time-consuming, typically requiring 2-8 min due to the repeated start-stop gantry motion synchronized with the respiratory gating signal. We propose a next-generation imaging paradigm, nonstop gated CBCT (ngCBCT), to substantially reduce acquisition time, lower imaging dose, and preserve image quality, thereby improving patient comfort and treatment accuracy.

    Current Research and Scholarly InterestsMy research develops AI systems for biomedicine, with a focus on multimodal learning, foundation models, and self-improving AI. I study how models can integrate medical images, clinical text, EHRs, and biomedical knowledge to support diagnosis, clinical workflows, and scientific discovery, while improving through feedback, evaluation, and human-AI interaction.

    BioMy research primarily focuses on the molecular mechanisms, signaling pathways, and therapeutic targets underlying cancer metabolism, particularly the m6A demethylase FTO. I am also actively exploring the interplay between tumor metabolism and tumor immunity, with the goal of identifying novel metabolic vulnerabilities for cancer treatment.

  • Xiaoxu Zhong

    Xiaoxu Zhong

    Postdoctoral Scholar, Radiation Physics

    BioI am a Postdoctoral Fellow in the Guillem Pratx Lab, with an expertise in predictive modeling, algorithm development, and data science. I earned my Bachelor of Science and Master of Science degrees in Ocean Engineering from Shanghai Jiao Tong University. I then received a Ph.D. in Mechanical Engineering from Purdue University, where I focused on developing mathematical models and applying machine learning. My work uncovered the mechanisms behind autoinjectors, drug delivery, and cavitation bubbles, with applications in tumor treatment and the design of medical devices. Currently, I am combining computational modeling and experimental approaches to positron emission tomography imaging, aiming to improve tumor diagnosis and treatment. I am also investigating how ionizing radiation nucleates nano-sized bubbles.
