Kerry Gilbert

Dr. Gilbert was born and raised in Austin, Texas. He attended The University of Texas and graduated in 1993 with a Bachelor of Science Degree in Kinesiology. In 1994 he moved to Lubbock, Texas to attend Texas Tech University Health Sciences Center (TTUHSC) to pursue his Master in Physical Therapy (MPT) Degree. After receiving his MPT degree (1997) and being licensed as a physical therapist, he worked in an outpatient orthopaedic setting at University Medical Center in Lubbock, Texas. He took an Assistant Professor faculty position in the TTUHSC, School of Health Professions (SHP), MPT Program in 1999. Since that time, he has completed his Certification in Orthopaedic Manual Therapy (COMT) through the International Academy of Orthopaedic Medicine-United States (IAOM-US; 2000), and completed his Doctor of Science (ScD) degree through TTUHSC in 2004. Dr. Gilbert has served as the TTUHSC MPT/DPT Program Director since 2004 and also has faculty appointments within the Transitional DPT, ScD, and PhD Programs within the Department of Rehabilitation Sciences. Dr. Gilbert was promoted to Associate Professor and was granted Tenure in 2009. In 2016 Dr. Gilbert was promoted to Professor. Dr. Gilbert coordinated the Musculoskeletal PT Practice track of the TTUHSC DPT curriculum for 10 years and now coordinates the Human (Gross) Anatomy course for the Department of Rehabilitation Sciences and contributes to the Physician’s Assistant Gross Anatomy course. He also serves as the Assistant Dean of Anatomy Research and Education for the School of Health Professions and the Director of the Clinical Anatomy Research Lab within the Center for Rehabilitation Research at TTUHSC. Dr. Gilbert was awarded the “Young Investigator Award” (2007) by SPINE and was co-author of the SPINE “Young Investigator Award” manuscript (2015) for his work in nerve root displacement and strain in unembalmed cadavers. He is also known for his work in intraneural fluid dynamics in response to neurodynamic mobilization. Dr. Gilbert serves as the TTUHSC representative to the State Anatomical Board of Texas. As Co-Director of the Institute of Anatomical Sciences, Dr. Gilbert is committed to excellence in anatomical teaching, research, and service, and is excited to help foster an interdisciplinary approach to anatomical education and investigation.

Roger James

Roger James is a professor of Rehabilitation Sciences at TTUHSC. He is Director of the Center for Rehabilitation Research, Director of the Clinical Biomechanics (Gait) Laboratory within the Center, and Program Director of the Ph.D. in Rehabilitation Science program. James holds a Ph.D. in Exercise and Movement Science from the University of Oregon with a specialization in biomechanics and emphases in sports medicine and motor control. He is a Research Fellow of the American College of Sports Medicine, TTUHSC University Distinguished Professor, School of Health Professions Excellence in Research Award recipient, and a member of the TTU Teaching Academy.

James's research focuses on reducing impairment and improving function in people who have or could develop potentially disabling movement disorders. His research objectives are to understand better the causes and consequences of gait dysfunction to reduce musculoskeletal injury and fall risk and improve mobility. Gait accommodation, or how people change their gait in response to physical and environmental challenges, is a central theme. Populations of interest include men and women of all ages who are healthy and who have mobility-altering health conditions.

James's research ranges from pre-clinical discovery of dysfunction mechanisms to early-stage clinical trials. It investigates potential intervention targets to improve function. His expertise includes biomechanical and neuromuscular factors that form the bases of movement. He incorporates research designs that control for individual differences, and he creates custom algorithms for data analysis. James collaborates with colleagues on research that aims to reduce impairment and improve function in people who have low back pain, nerve-related pain, and postural control (balance) disorders.

Candace Hicks

Candace Bourland Hicks has directed the Center for Speech, Language, and Hearing Research in the School of Health Professions at Texas Tech University Health Sciences Center since 2013. In this role, she has had the opportunity to support research in the areas of audiology, hearing science, speech-language pathology, and speech science. Her research interests have focused on pediatric audiology and on listening effort. These areas of research are guided by her clinical experiences with pediatric audiology, along with her training in research. Her long-term research goals are to determine the effort and fatigue caused by listening in less than optimal listening conditions, particularly in school-age children, and to evaluate the use of amplification/assistive devices for children in school environments. Dr. Hicks has multiple peer-reviewed publications and consistently provides peer-reviewed presentations at state and national venues. She is able to use her research experience to guide both audiology clinical research projects, in addition to guiding Ph.D. students in the department. She also strives to provide support for faculty in the Department of Speech, Language, and Hearing Sciences to succeed in their individual and collaborative projects.

Carleigh Smith

Carleigh Smith is Unit Manager of Research for the TTUHSC School of Health Professions (SHP). Her role is to implement and manage systems and processes that promote best practices for faculty with the aim to support, educate, and encourage the pursuance of research grants, innovations and discoveries, and collaborations with the goal of advancing the research enterprise.

Carleigh first began working for TTU in the History Department during her undergrad in 2011. Following graduation in 2014, she took a position in the Graduate School’s Enrollment Services team. She managed the Graduate School’s; enrollment records, work flows, registrar duties, graduation, retention programs, as well as, assisted in graduate school’s policy developments. She continued her career at TTU and pivoted from higher education administration to commercialization at the new Innovation Hub at Research Park in 2017. She managed the Innovation Hub’s; operations, office affairs, business, external events, and accelerator programs. She specialized in implementing various systems and processes to achieve the high volume of diverse requests. She gained tremendous experience in working in a fast-paced, startup atmosphere and eager to continue that culture in her new career.

Carleigh decided to move the TTUHSC School of Health Profession’s for the unique opportunity to take her experiences and implement them to further develop and grow the research enterprise at the HSC. She aims on building a sustainable research office model for SHP that is a direct support-line for faculty wishing to pursue research scholarship.

Carleigh LOVES working for Texas Tech, and is a proud Red Raider! In her spare time, she enjoys spending time with her dogs, traveling the world, and Red Raider sports! She will be continuing her education by pursing a Master’s in Business Administration at TTU.
