Patty Carlson-Kuhta

Sr. Research Associate: Patty Carlson-Kuhta

I received my PhD in Physiological Science at the University of California, Los Angeles and also completed a postdoctoral fellowship at UCLA in the Neuropsychiatric Institute. I have studied the sensorimotor control of stereotyped limb movements and brain plasticity during development following cortical lesions. My current research focuses on posture and gait deficits in people with Parkinson’s disease; specifically looking at how Deep Brain Stimulation for Parkinson’s disease affects balance, and the use of wearable motion sensors to quantify movement deficits.

Geetanjali Gera Dutta

Postdoctoral Researcher: Geetanjali Gera Dutta

Geetanjali Gera Dutta received her Physical Therapy degree from the Post Graduate Institute of Medical Education and Research, Chandigarh, India. She received her Master¹s degree in the Human Motor Control Laboratory at the University of Delaware. She went on to earn her Doctorate Degree in the same laboratory from the Interdisciplinary Program in Biomechanics and Movement Science at the University of Delaware. Her dissertation work focused on understanding the coordination deficits in reaching movements post-stroke. Geetanjali is interested in developing better rehabilitation strategies for neurologically impaired individuals. In order to do so, she is interested in quantifying the underlying motor deficits and understanding the mechanisms behind the atypical movement patterns observed in such individuals.

Brett Fling

Postdoctoral Researcher: Brett Fling

Dr. Fling received his PhD in neuromotor control from the University of Michigan in 2011. Brett is currently investigating MS-related declines in proprioceptive control of upright stance. These projects use behavioral and neuroimaging techniques to characterize functional neural activation and connectivity in central proprioceptive pathways in patients with MS. These studies aim to determine whether alterations in proprioceptive neural networks underlie balance deficits in MS. Brett is also investigating the neural bases underlying freezing of gait in PD. These projects use structural and functional neuroimaging with an emphasis on determining the extent to which frontal lobe problems are important rehabilitation considerations for mobility disability.

The long-term objectives of Brett’s research are to: 1) understand how the healthy brain integrates sensorimotor information to control goal-directed, voluntary movement of the upper extremities and how this control changes with advancing age, 2) better understand the role proprioceptive feedback plays in balance control, and 3) develop strategies that promote neural plasticity and functional recovery subsequent to aging and/or disease, with an emphasis on Multiple Sclerosis (MS) and Parkinson’s Disease (PD).

Laurie King, PhD, PT

Assistant Professor: Laurie King, PhD, PT


Dr. Laurie King is currently an assistant professor in the department of Neurology. She received her Doctor of Philosophy degree from Medical College of Virginia in Richmond, Virginia, in Anatomy and Neurobiology. Prior to that, she graduated from Mayo School of Heath Sciences in Rochester MN with a Masters in Physical Therapy. She has over 15 years clinical experience treating neurologically impaired patients. Her work as a post-doctoral fellow at OHSU led to the development of an agility-based sensory motor exercise program for Parkinson's disease and she is currently coordinating a clinical trial comparing two, evidence-based rehabilitation programs for Parkinson's disease. Additionally, she has expertise in using sensitive technology, such as gait analysis, motion analysis, dynamic posturography and inertial sensors, for assessment and quantification of mobility. Dr. King has 2 active and funded lines of research; one in the area of exercise and Parkinson's disease and the other in the area of traumatic brain injury and balance assessment.

Julia Marshall Leach

Ph.D. Student: Julia Marshall Leach

Julia received her BS in Engineering and BA in Psychology from Gonzaga University in 2010. She is currently working towards a Ph.D. in Biomedical Engineering at OHSU’s School of Medicine. Julia is a Ph.D. candidate for the class of 2015. She is working with her mentors, Fay Horak (Neurology, Balance Disorders Laboratory) and Tamara Hayes (Biomedical Engineering, Point of Care Laboratory), to study the relationships between postural control, cognition, and falls in elders with Mild Cognitive Impairment. She is particularly interested in the associations between motor and cognitive decline in our aging population.

Martina Mancini

Postdoctoral Researcher: Martina Mancini

Dr Mancini received her Ph.D. in Biomedical Engineering from Alma Mater Studiorum, University of Bologna, Italy in 2009. She joined Balance Disorders Lab in July 2010 as a post-doctoral fellow, and she is currently working on development and validation of algorithms to analyze posture and postural transitions by means of wearable inertial sensors, with a particular focus on Parkinson’s disease. 

Actually, her goals are in understanding how balance deteriorates with disease progression, and how balance is influenced by medications and deep brain stimulation. Also, she is interested in understanding if posture and postural transition are possible predictors of falls in normal aging as well as in Parkinson’s disease.

Amie Peterson, MD

Neurologist: Amie Peterson

Amie Peterson, MD is currently a fellow in movement disorders focused on the care of Parkinson’s patients and related disorders. Her current research project is looking at the relationship between vitamin D levels and balance in persons with Parkinson’s disease. Dr. Peterson is also involved in advocacy work at a local and national level.

Daniel Peterson

Postdoctoral Resarcher: Daniel Peterson

Daniel received his Ph.D. from Washington University in St. Louis, where he investigated the neural control of locomotion in people with Parkinson disease using functional neuroimaging. Other previous research experiences include a Master's degree from the Pennsylvania State University focused on age related changes in walking, and a research fellowship at Steadman Philipon Research Foundation using bi-plane fluoroscopy to quantify knee kinematics during drop landings in individuals prone to anterior cruciate ligament injury.

Daniel's current work focuses on understanding balance and postural control deficits in a number of clinical populations. He is also interested in how postural control can be improved by rehabilitation using principles of motor learning.

Carolin Curtze

Postdoctoral Researcher: Carolin Curtze

Carolin joined the Balance Disorders Lab in 2012 as a postdoctoral fellow. Prior to that, she worked on her PhD in Medical Sciences from the University of Groningen, the Netherlands. In her dissertation she studied the neuromechanics of movement in lower limb amputees. Carolin’s current research focuses on posture and gait deficits in people with Parkinson’s disease. The emphasis of her work is on the development and validation of algorithms to analyze posture and gait by means of wearable inertial sensors. Her long-term goal is to gain more insight into the adaptability and plasticity of the human motor system.
