McKell Woodland, BS
Rice University Ph.D. Student
McKell is a Ph.D. candidate in the Computer Science Program at Rice University. She received her B.S. in Applied and Computational Mathematics with a minor in Computer Science from Brigham Young University.

McKell’s research focuses on utilizing generative adversarial networks (GANs) to detect these out-of-distribution inputs. Her research has applications in warning clinicians when a deep learning-based segmentation model likely failed, flagging which images should be reviewed when large amounts of data are automatically segmented, determining which images in large cohorts of data would have the most utility to label, and improving datasets and model capabilities over time by diversifying data.

Aashish Gupta, MS
GSBS Ph.D. Student
Prior to joining the lab, he obtained his B.S. and M.S. from Texas Tech University, and the UTHealth Houston MD Anderson Cancer Center Graduate School of Biomedical Sciences, respectively. In his free time, he likes to play tennis, Gaelic football and do weightlifting.
After 3-6 months of radiotherapy, there is an increase and decrease in the volume of liver in the region of low and high radiation dose, respectively. Aashish’s Ph.D. project focuses on developing AI based anatomical models to describe the response of liver to radiation. He plans to accomplish three major milestones in his project. Firstly, he is developing AI based contouring infrastructure to auto-contour liver segments on CT and MRI scans to quantify the volumetric change. Secondly, he plans to develop both machine and deep learning models to predict the longitudinal volumetric response of liver segments after radiotherapy. Thirdly, he plans to investigate how functional imaging modalities such as SPECT and DCE-MRI could help describe physiological and volumetric change in liver when radiation is administered. Once the segmental response of liver is clearly known, clinicians will be able to better spare the sensitive parts of liver which would decrease the risk of hepatic failure and increase the survival rate post-therapy.
Erin Snoddy
GSBS Ph.D. Student
Erin is a Medical Physics Ph.D. student in the GSBS (Graduate School of Biomedical Sciences) program. She received her B.A. in Astrophysics with a minor in English Literature from Swarthmore College.

Erin’s research interests are centered on correlative medical and diagnostic imaging (especially non-ionizing imaging modalities). Her current research focuses on the correlation of MR imaging with histology to determine anatomical characteristics of the breast. The goal is to use this information to improve breast reconstructive techniques for breast cancer patients who have had mastectomy procedures.
Brandon Reber, B.S.
GSBS Ph.D. Student
Brandon is a Medical Physics Ph.D. student in the Morfeus Lab. He obtained his Bachelor of Science degree in Physics at the University of British Columbia in Vancouver, Canada. His undergraduate research project focused on validating a machine learning technique for the identification of Parkinson's disease in individuals using PET images. He feels like project was a great introduction to medical imaging and machine learning, and how they can be used to solve problems in the clinic. In his spare time, he currently enjoys exploring Houston and trying out the many restaurants the city has to offer.
Brandon's Ph.D. project uses machine learning methods to predict osteoradionecrosis (ORN) resulting from head and neck cancer radiation therapy. These machine learning methods include traditional techniques such as support-vector machines as well as more recent methods such as convolutional neural networks (CNNs). First, his project will look at using data acquired prior to the start of radiation treatment for ORN prediction. This data can include radiation treatment plans and treatment planning computed tomography (CT) images. Next, he will examine functional imaging for this task. These imaging modalities can capture physiological changes in patients associated with ORN. Finally, the last portion of his project will examine using changes in imaging features from different treatment timepoints for ORN prediction. At the conclusion of this project, he hopes to improve the early identification of ORN resulting from head and neck cancer radiation therapy, allowing for earlier interventions, alternative treatment strategies, and improved patient quality of life post-treatment.
