Justin Grodin, M.D.

Justin Grodin, M.D.
Assistant Professor
Internal Medicine

Dr. Grodin is a cardiologist with expertise and clinical focus in advanced heart failure, cardiac amyloidosis, hypertrophic cardiomyopathy, cardiac transplantation, left-ventricular assist devices, and cardiac critical care. In addition, he splits his time as a clinical epidemiologist focusing on heart failure outcomes research. His THR Clinical Scholars project focuses on identifying novel “phenotype groups” of patients hospitalized with decompensated heart failure and characterizing their unique risk-profiles in order to tailor heart failure readmission prevention strategies. This project will leverage truly “big data” from the enormous THR electronic health record database with advanced computational analytics at UT Southwestern.

Arthur Hong, M.D.

Arthur Hong, M.D.
Assistant Professor
Internal Medicine and Clinical Sciences

Dr. Hong is a practicing general internist and health services researcher. He is interested in the design, implementation, and evaluation of patient-centered, value-based innovations to clinical care. This interest is rooted in understanding the problems patients and clinicians face when making clinical decisions while facing uncertainty. Dr. Hong approaches research questions with an eye toward the implications for patients, clinicians, health systems, and health policy. He has completed prior work that evaluated the impact of the Choosing Wisely campaign, as well as examined financial incentives and variation among clinicians when ordering non-recommended medical care. He is currently working on evidence-based approaches to improve the design and delivery of cancer care.

Amy Hughes, M.D.

Amy Hughes, Ph.D.
Assistant Professor
Population and Data Sciences

Dr. Amy Hughes’ research background includes training in geospatial information sciences, econometrics, spatial statistics, and cancer prevention and control. Her research interests include applications of spatial statistics and econometrics to understand geographic differences in health behaviors, outcomes, and policies. Her past research has focused on using large surveillance, administrative, and electronic medical record databases to investigate how patient, physician, health system, environmental, and neighborhood factors influence health behaviors and outcomes. Dr. Hughes’ THR Clinical Scholars work will focus on using geospatial methods to identify patient contexts that carry high risk for diabetes, asthma exacerbations, and poor management of multimorbid conditions.

Nneka Ifejika, M.D., M.P.H.

Nneka Ifejika, M.D., M.P.H.
Associate Professor
Physical Medicine & Rehabilitation, Clinical Sciences, and Neurology & Neurotherapeutics

Over 300,000 of the 795,000 people who experience a stroke in the United States annually have moderate to severe impairments. These impairments make early and effective stroke rehabilitation a critical component of the recovery process. Dr. Ifejika’s research focuses on the synthesis of existing acute stroke and rehabilitation data sets to create “optimal rehabilitation” prediction models. “If we can identify patient characteristics that increase the probability of receiving intensive stroke rehabilitation early in the acute stroke hospitalization, opportunities to streamline referrals, decrease hospital length of stay, and improve functional outcomes will follow.” As Section Chief of Stroke Rehabilitation at UT Southwestern Medical Center, Dr. Ifejika’s clinical interests center on the provision of stroke rehabilitation protocols throughout the Peter O’Donnell Brain Institute. From the Neuro ICU to outpatient clinics, the process of care is evidence based, patient-centered, and collaborative. In her role as North Central Texas Trauma Regional Advisory Council (NCTTRAC) Co-Director of Stroke Research, she collaborates with EMS organizations and Stroke Centers throughout the Dallas-Fort Worth region, identifying opportunities to decrease the disability burden of cerebrovascular disease.

Bradley Lega, M.D.

Bradley Lega, M.D.
Assistant Professor
Neurological Surgery, Psychiatry, and Neurology & Neurotherapeutics

Dr. Lega studies human memory using direct brain recordings. This unites his research interests with his clinical practice treating patients with intractable epilepsy. The long term goal of this research is to develop a brain machine interface device to treat memory disorders. Funding through the THR mechanism has helped him test new hypotheses about the modulation of human memory and create first of its kind data exploring the utility of parietal lobe modulation to treat memory loss.

Ambarish Pandey, M.D.

Ambarish Pandey, M.D.
Assistant Professor
Internal Medicine

Dr. Pandey is a preventive cardiologist with clinical interest in prevention and management of heart failure, particularly heart failure with preserved ejection fraction. His research interest is focused on predicting and preventing heart failure at a population level. His work has particularly focused on lifestyle risk factors such as obesity and physical inactivity as potentially modifiable targets for prevention of heart failure. As a THR research scholar, he is developing novel, EMR-based screening strategies that can be implemented within our health system to identify the highest risk individuals for heart failure development and target them with effective preventive interventions.
