Eva Müller-Oehring, PhD
Senior Research Scientist

Dr. Eva M. Müller-Oehring is a Senior Research Scholar with a joint appointment in the Departments of Neurology and Psychiatry at Stanford University School of Medicine, and at SRI International. Dr. Müller-Oehring received her undergraduate and graduate education in Germany, where she studied Psychology at the University of Trier and obtained her Ph.D. in Neuropsychology and Cognitive Neuroscience at the School of Medicine, Otto von Guericke University Magdeburg (OVGU). She did her Clinical Psychology postgraduate studies at the Institute of Behavioral Therapy Lübben (Germany) in accordance with the German Approbation Law for Clinical Psychology, and her internship in at the Department of Psychiatry at OVGU. She completed her postdoctoral fellowship in neuroimaging, alcohol use disorder, and psychiatric diseases affecting the brain with Dr. Edith V. Sullivan at Stanford Psychiatry (USA).

Dr. Müller-Oehring's research interests aim to advance our understanding on ‘how the human brain works’ by studying the relationship between brain structure and function using multimodal imaging approaches in healthy and degraded brain systems. Her current studies focus on neurodegenerative processes, cognitive impairment, motor dysfunction, and modulators of disease severity in people aging with HIV infection, in Parkinson’s disease, and alcohol use disorder. In addition, she studies the dynamic neurodevelopmental plasticity in adolescents transitioning to adult cognitive maturity and emotional control as part of the National Consortium on Alcohol and Neurodevelopment in Adolescence (NCANDA). At Dr. Poston’s laboratory, Dr. Müller-Oehring is expanding her neuroimaging research to PET/MR aiming to identify biomarkers underwriting the functional status in Parkinson’s disease.

Outside of work, Dr. Müller-Oehring enjoys nature, being around horses, running, hiking, and skiing in California and the Alps, and summitting Mount Whitney with her family.

Kristen Wheeler, PT, DPT
Research Assistant

Kristen graduated with a Bachelor of Science degree from Appalachian State University where she studied Exercise Science. Following her undergraduate training, she received a Doctor of Physical Therapy degree from Duke University in 2014. She worked as a physical therapist primarily with the geriatric population in home health and skilled nursing facilities. After working in healthcare for several years, Kristen realized that there is a need for major improvements in diagnosing and treating various conditions. This led to her desire to become involved in research. Kristen hopes to bring her clinical background into the research world to help discover ways of making a greater impact in the lives of the patients she has treated. She recently moved from Colorado to California and joined the Poston Lab in August 2020. Outside of work, she enjoys running, hiking and going on adventures with her husband and golden retriever.

Alena Smith
Research Assistant

Alena graduated from the University of Southern California with a Bachelor of Science in Neuroscience and minor in Business Administration. During her time as an undergraduate research assistant at the USC Brain and Creativity Institute, Alena learned to blend her experiences as an artist and scientist to investigate the neurological correlates of creativity. She is excited to apply these understandings and learn more about the cognitive changes associated with Parkinson’s disease.

Alena is passionate about empirically connecting PD pathology to patient anecdotes of sudden bursts of artistic creativity. Above all, she is driven to better understand the symptomatic and neurophysiological bases of PD to help develop more effective treatments. She hopes to pursue graduate education where she can obtain greater clarity in her role as a researcher and artist. Outside of research, Alena spends her time painting and drawing. She runs her own small art business and hosts annual art shows to raise money for the Epilepsy Foundation.

Carla Abdelnour, MD, PhD
Postdoctoral Scholar

Originally from Caracas, Venezuela, Dr. Carla Abdelnour received her medical degree at the Central University of Venezuela, and then completed her neurology residency training at the University Hospital Príncipe de Asturias in Madrid, Spain. She conducted her doctorate in Medicine at the Autonomous University of Barcelona working with Drs. Dag Aarsland, Javier Pagonabarraga and Jaime Kulisevsky.
