Biomedical and Geometric Computing Laboratory (BigC)
PI: Ovidiu Daescu, Professor of Computer Science at UT Dallas
BigC focus is on developing fast algorithms with guaranteed performance for biomedical applications with inherent geometric structure. Using machine learning and deep learning approaches on multimodal images, such as MRI and digital pathology (WSI) cancer images, and exploiting geometric structures that arise in nuclei and cell distribution, we are developing algorithms that can be used to predict treatment outcome and allow to personalize treatment. Similarly, by modeling 3-dimensional images of organs and tissue in the human body as “importance weighted” geometric objects, we are able to develop software that can be used to guide medical procedures, like biopsy and surgery, for hard to reach places in the human body. All our algorithms rely on proven theoretical properties associated with the problem and exploit those properties to guarantee performance.

Molecular Imaging and Optical Nanotherapeutics (mION) Laboratory
PI: Girgis Obaid
Assistant Professor of Bioengineering at UT Dallas
The mION lab focuses on developing optically-activated nanotherapeutics using molecular imaging as an informant for their intelligent engineering, a diagnostic, and a means for image guided surgery and photo-deposition of tumor therapy. Theranostic nanoparticles for cancer imaging and therapy require synchronization between nanotechnology and nanoengineering with tumor biology. Non-invasive techniques in optical, magnetic and radiographic imaging deliver critical insights into the molecular interactions of such theranostics nanoparticles with tumor compartments and biomolecules, thereby aiding in the function-driven optimization of nanoparticles. Furthermore, innovative approaches in tumor activatable nanoparticles are pursued with the goal of enhancing the specificity of tumor detection, tumor margin delineation and efficiency of post-tumor resection phototherapy of residual disease.

The research will combine multimodality imaging and multidimensional data to exploit our current knowledge of the genetic and molecular bases of various diseases and therefore to have substantial positive implications for disease prevention, detection, diagnosis, and therapy.

Targeted Neuroplasticity Lab (TNPL)
PI: Seth Hays, Associate Professor of Bioengineering at UT Dallas
The targeted neuroplasticity lab employs elements of neuroscience and biomedical engineering to develop treatments for human disease. The primary research focus of the lab is to develop new strategies to enhance neuroplasticity, or the ability of the brain to change, in order to treat neurological disease. The majority of current studies evaluate the ability of vagus nerve stimulation (VNS), a putative targeted plasticity therapy, to improve recovery of motor dysfunction. We are rigorously testing VNS to enhance recovery in clinically-relevant animal models of stroke, peripheral neuropathy, and spinal cord injury. In addition to further development and optimization of targeted plasticity therapy, we are investigating the cellular and molecular mechanisms that underlie this recovery. Finally, building on our success in animal models, we are in the process of translating VNS-based targeted plasticity therapy to clinical investigation in patients with chronic stroke and spinal cord injury.
Tissue Mechanics & Remodeling (TMR) Laboratory
PI: Jacopo Ferruzzi, PhD
Assistant Professor of Bioengineering at UT Dallas
The TMR Lab was established at UT Dallas in August 2020. Research in the TMR Lab is aimed at improving fundamental understanding of diseases associated with – and driven by – abnormal tissue mechanics, such cardiovascular disease and cancer. Dr. Ferruzzi worked extensively in the area of cardiovascular biomechanics between the University of Pisa, Texas A&M University, and Yale University. He studied the progression of arterial stiffening and developed methods for “biomechanical phenotyping” arterial sections in vivo and ex vivo. By using experimental and computational methods, he investigated vascular conditions such as arterial aging, chronic hypertension, abdominal aortic aneurysms, and thoracic aortic dissections. While at Boston University, Dr. Ferruzzi explored the role of biomechanics in breast cancer by employing 3D cell culture techniques and label-free imaging methods. He investigated the mechanisms underlying collagen remodeling upon tumor growth and the mechanics of collective cancer invasion. His research program at UT Dallas employs a multidisciplinary and multiscale approach to dissect the relationship between altered mechanical properties, extracellular matrix organization, and cellular function.

Vascular Mechanobiology Laboratory (VMBL)
PI: Heather Hayenga, Assistant Professor of Bioengineering at UT Dallas
The Vascular Mechanobiology Laboratory aims to understand and prevent the progression of cardiovascular diseases through the use of experimental and computational models. Improved computational tools to aid in diagnosis and prognosis of atherosclerosis are needed. The VMBL uses an integrative computational approach to predict the growth, remodeling and instability of atherosclerosis in a coronary artery. Specifically, we combine agent based modeling (ABM) with finite element analysis (FEA) and computational fluid dynamics (CFD) to create a modeling tool capable of handling mechano-geometric and chemo-biological complexities to a degree existing approaches cannot. Together this modeling tool will be insightful for individualized decision making, understanding key underlying factors of plaque progression, and foundational for design changes in interventional procedures.
