Todd Aguilera, M.D., Ph.D.

Todd Aguilera, M.D., Ph.D.

Todd Aguilera, M.D., Ph.D., is a physician-scientist trained as a radiation oncologist with expertise in molecular engineering, molecular imaging, the tumor microenvironment, and tumor immunology. 

Dr. Aguilera completed the Medical Scientist Training Program in 2011 at the University of California San Diego. He obtained his Ph.D. in 2009 in Dr. Roger Y. Tsien's laboratory, which received the 2008 Nobel Prize in Chemistry. His Ph.D. work focused on engineering and validating activatable peptide-based probes to target the tumor microenvironment. Molecules that stemmed from his work are currently being tested in clinical trials for fluorescence-guided surgery of breast cancer.

After an internal medicine internship in San Diego, he joined the Radiation Oncology Residency program at Stanford University. He worked with Dr. Amato Giaccia as a resident and postdoctoral fellow studying factors in the tumor microenvironment that promote ​immunologic tolerance and developing therapeutic approaches to improve immunotherapy responses in solid tumors. More specifically, he is interested in intrinsic factors that prevent/suppress the anti-tumor immune response after radiation and how these factors can be reversed. 

Dr. Aguilera was recruited to the Department of Radiation Oncology at UT Southwestern to establish his research group which will continue to investigate the immune microenvironment and engineer approaches to target cells and molecules that lead to immune privilege. He treats radiation oncology patients with gastrointestinal cancers, is developing laboratory projects in pancreatic cancer, and aims to establish collaborative projects with clinicians and researchers.

Outside of the lab, Dr. Aguilera enjoys spending time snowboarding, surfing (when he can escape back to California for a few days), brewing beer, and spending time with his family. His wife is also on faculty at UTSW in the Division of Neonatology. He has a young son and daughter whom he looks forward to taking to the mountains and ocean.

Current Lab Members

Derek Abbott, Ph.D.

Derek Abbott, Ph.D.

Postdoctoral Fellow

Derek Abbott, Ph.D., received his Ph.D. in molecular and cellular biology from Baylor College of Medicine in October 2023. His research focused on developing novel biosensor assays to detect the effects of endocrine disrupting chemicals on estrogen receptor β, a key driver in several diseases. His doctoral work led to the creation of the first high-throughput screening platform for endocrine disrupting chemicals impacting ERβ. He also contributed to developing a transgenic zebrafish model for simultaneous screening of both estrogen receptor subtypes activity. Prior to his graduate studies, Dr. Abbott received his B.S. from Brigham Young University where his early work focused on screening natural metabolites with anti-cancer potential.  


Dr. Abbott joined UT Southwestern as a postdoctoral fellow in early 2024 as part of an interdepartmental collaboration between the Lyda Hill Department of Bioinformatics and Radiation Oncology. Dr. Abbott’s current project aims to bring together resources and expertise from this six PI collaborative effort to understand the molecular mechanisms of therapy resistance in colorectal cancer. His interests include lightsheet microcopy, multiplex immunofluorescence, expansion microscopy, spatial biology, pipeline development, and 3D image analysis.

Eslam Elghonaimy, Ph.D.

Eslam Elghonaimy, Ph.D.

Instructor

Eslam Elghonaimy, Ph.D., earned his Ph.D. in cell biology and genetics from Cairo University, Egypt, in 2016. He completed postdoctoral training at Universitätsklinikum Münster, Germany, before joining the Aguilera Lab at UT Southwestern in 2018 as a postdoc. His research focuses on the dynamic interplay among tumor, stromal, and immune cells within the tumor microenvironment and how these interactions influence tumor initiation, progression, and therapeutic response.

Dr. Elghonaimy expanded his interests into computational biology through the UT Southwestern Bioinformatics and High-Performance Computing (BioHPC) fellowship, enabling him to integrate bioinformatics with biological research. He has developed pipelines for single-cell RNA sequencing (scRNA-seq), CITE-seq, and immune repertoire analyses, special genomics, applying these tools to clinical trials to explores immunotherapy and radiation therapy.

A recent highlight of his work is the co-development of INSPIRE-seq, a novel platform combining nanobody technology, phage display, and next-generation sequencing to identify immune cell nanobodies within the tumor microenvironment.
