Lab Members

  • Assistant Professor of Therapeutic Radiology

    Dr. Thomas Hayman is an Assistant Professor of Therapeutic Radiology. He received his medical degree from the University of South Florida Morsani College of Medicine, and his PhD in Molecular Medicine as part of the University of South Florida Morsani College of Medicine/ National Institutes of Health Graduate Partnership Program mentored by Dr. Philip Tofilon. He completed his residency in Radiation Oncology at Yale New Haven Hospital. Dr. Hayman cares for patients with lung, lung, head and neck, and skin cancers, among others. He is trained in stereotactic radiosurgery using Gamma Knife Icon, as well as IMRT for head and neck, central nervous system, prostate, thoracic, gastrointestinal, hematologic, and gynecologic malignancies, and SBRT lung, liver, pancreas, and spinal tumors. During his PhD training and time as a Holman Research Pathway Fellow, Dr. Hayman focused his research on basic and translational radiation oncology with an emphasis on the discovery of determinants of cellular radiosensitivity. As such, the overarching theme of Dr. Hayman's laboratory is to understand mechanisms of resistance to DNA-damage with the goal of developing novel approaches to neutralize the adaptive responses with the ultimate goal of clinical translation.
  • Postdoctoral Associate

    Irma Dominguez-Vigil earned her undergraduate degree in Pharmaceutical Biology and Chemistry at the School of Chemistry, from the Universidad Autonoma de Nuevo Leon (UANL) in Mexico (2013). She then obtained her Master’s degree in Pharmacy under the supervision of Dr. Benito Mata-Cardenas and Dr. Maria Camacho-Corona at the School of Chemistry, UANL (2015). Later, she earned a PhD degree in Molecular Biology and Genetic Engineering at the School of Medicine, UANL (2020), under the mentorship of Dr. Hugo A. Barrera-Saldana, where she explored genetic biomarkers using noninvasive techniques, such as liquid biopsies, as diagnostic tools for the early detection of gynecological cancers. During her doctoral studies, she obtained an International Academic Exchange Award (CONACyT) to Collaborate at Nuvance Health in Danbury, CT (2018-2020), where she worked with Patient Derived Cell Lines isolated from endometrial, ovarian, and sarcoma tumors as preclinical models for drug sensitivity. Presently, Dr. Dominguez-Vigil has been working on the effects of the small molecule CFI-400945 as an enhancer of radiation therapy in Non-small cell lung cancer (NSCLC) and exploring the interaction of STING with the response to DNA damaging therapy in Head and neck squamous cell carcinoma (HNSCC.
