Principal Investigator

Virendra R. Mishra, Ph.D.
Virendra R. Mishra is an Associate Professor in the Department of Radiology at the University of Alabama at Birmingham. He got his Ph.D. in 2014 from the joint degree program between the University of Texas at Southwestern Medical Center in Dallas, TX, and the University of Texas at Arlington, TX. He was a staff scientist at Cleveland Clinic, Nevada for 7 years (between 2015 – 2022) before his move to UAB. Dr. Mishra develops novel computational tools for the analysis of various MRI modalities for understanding early-stage Parkinson’s disease (PD) and non-motor symptoms of PD with disease progression. His current interest is developing machine learning/deep learning algorithms by fusing various MRI modalities to predict cognitive decline in PD and also due to repeated head impacts. His research is funded by the National Institute of Health and philanthropic organizations in the past.

He also conducts neuropsychological data analysis to identify early markers of cognitive decline in Parkinson’s disease.
Dr. Chaurasiya has presented at national and international conferences and has authored more than 45 peer-reviewed publications, along with two book chapters and two patents.

Research Coordinator

Leticia Mason
Leticia is responsible for organizing participant recruitment and enrollment, coordinating patient care, and follow-up appointments required by study protocols. Her responsibilities extend to the coordination and organization of MRI observational scans.
She worked as a patient care technician on the postpartum and newborn nursery unit for 17 years and was a clinical research coordinator in Maternal Fetal Medicine and the O’Neal Comprehensive Cancer Center. Leticia has a range of both clinical and lab experiences that help her serve as a liaison between primary investigators, clinical staff, and research support for the Department of Radiology.
Graduate Students
Gaurav N. Rathi
Gaurav is a Ph.D. student in Biomedical Engineering at the University of Alabama at Birmingham, where he also completed his M.S. in Computer Science in 2023. Before beginning his doctoral training, he worked as a Senior Researcher in the Department of Radiology at UAB, where he developed machine learning and deep learning models for multimodal MRI analysis in neurodegenerative diseases, with a particular focus on Parkinson’s disease. His work has included predictive modeling of Freezing of Gait (FOG), Mild Cognitive Impairment (MCI), and BrainAGE, as well as harmonization of diffusion MRI across multi-site datasets.
Gaurav brings a strong background in computer science, full-stack development, and software engineering, having designed tools and platforms for clinical and research use, including radiation therapy planning and digital health applications. His current research focuses on integrating structural MRI, diffusion MRI, and functional MRI with clinical measures to discover biomarkers for disease subtyping and staging, with an emphasis on precision diagnostics and personalized healthcare.


Ivan Campbell
Ivan Campbell is a PhD student in Clinical and Counseling Psychology at the University of South Alabama, studying clinical neuropsychology. During his undergraduate studies at the University of Georgia, he developed an interest in behavioral neuroscience, clinical neuroimaging, and informatics, which now guides his research. He is interested in the application of novel analytic methodologies to neuroimaging data to uncover new information about the relationship between the brain and behavior, particularly within clinical populations. He is especially interested in the early detection and prevention of neurological conditions such as dementia and Parkinson’s Disease. His clinical interests also include neuropsychological assessment and rehabilitation.
Research Assistant
Neha Singhal
Neha is a junior at the University of Alabama at Birmingham, majoring in Neuroscience on the pre-medical track. She is passionate about applying computational approaches and advanced statistical analysis to neuroimaging data to uncover insights into brain-behavior relationships.
Her research focuses on early detection and prevention of neurodegenerative conditions, particularly Parkinson’s disease, using brain connectivity patterns as potential biomarkers for disease onset. She aims to bridge basic neuroscience research with clinical applications, developing innovative diagnostic tools that shift healthcare from reactive treatment to proactive prevention and personalized intervention strategies for improved patient outcomes.

Alumni
Taylor Davis
Taylor Davis is a doctoral candidate in the Behavioral Neuroscience Program from Birmingham, AL. She currently works on a project looking at the fractional amplitude of low-frequency fluctuations (fALFF) regarding the freezing of gait aspect of Parkinson’s disease. Taylor intends to go into an industry-related position after completing her doctorate. Taylor enjoys the collaborative flexibility at the EN4D2 Lab!


Alan Gardner
Alan Gardner is a junior at the University of Alabama at Birmingham, where he is majoring in Neuroscience. Additionally, Alan is an honors student on the pre-med track. His interest in medicine is rooted in his desire to close the gap that exists within healthcare. As a minority, Alan is directly impacted by the racial disparities that exist within medicine. He understands that these disparities disproportionately affect many people of color and result in poor patient outcomes. Therefore, he plans to pursue a career in medicine to play an active role in bridging the gap that exists within healthcare. When he is not busy studying, he enjoys spending time in the research lab, training for marathons, weightlifting, and playing piano.
Rotating Students
Saul Gurgua Lopez
Saul Lopez is a doctoral student in the Neuroengineering program, a joint program between the University of Alabama at Birmingham (UAB) School of Engineering and Heersink School of Medicine, and a researcher for the EN4D2 Lab.
