Kristy Townsend, PhD
Associate Professor
Department of Neurosurgery
The Ohio State University | Wexner Medical Center

Kristy Townsend holds a Ph.D. in Neuroscience and has been investigating the brain and nervous system in the regulation of energy balance and metabolism for the past 20 years. Townsend is now Associate Professor in the Department of Neurological Surgery at The Ohio State’s Wexner Medical Center. Research in the Townsend Lab for Neurobiology & Energy Balance (ktownsendlab.com) at The Ohio State University focuses on neural plasticity (or, remodeling and regeneration) and how the brain and nervous system impact appetite, metabolism, and energy expenditure (or, calorie burning). Townsend is involved in neuropathy research in three ways: 1) the laboratory investigates how nerve endings can die back into the adipose tissue (or, fat tissue) under the skin in conditions of small fiber neuropathy and how this impacts metabolic health; 2) the laboratory researches mechanisms of neuropathy and potential treatments in cases of diabetes or aging; and 3) Townsend and colleagues are working on a medical device for the functional diagnosis of small fiber neuropathy through an academic spin-out company called Neuright, Inc.

Ahmet Hoke MD

Ahmet Höke, MD, PhD, FRCPC
Professor of Neurology and Neuroscience
Director, Neuromuscular Division
Johns Hopkins School of Medicine
Baltimore, MD

Following appointment to neurology faculty at Johns Hopkins School of Medicine in 1999, he rose through the ranks and became Professor of Neurology and Neuroscience in 2009. Currently he is the W.W. Smith Charitable Trust Professor of Neuroimmunology, Director of the Daniel B. Drachman Division of Neuromuscular Diseases and Director of the Merkin Peripheral Neuropathy and Nerve Regeneration Center at Johns Hopkins School of Medicine.

Sandra Rieger, PhD
Associate Professor
Department of Biology, Sylvester Comprehensive Cancer Center
University of Miami
Coral Gables, FL

Dr. Rieger is an associate professor in the Department of Biology at the University of Miami and affiliated with the Sylvester Comprehensive Cancer Center at the Miller School of Medicine. Dr. Rieger’s research focuses on understanding the underlying mechanisms responsible for chemotherapy-induced peripheral neuropathy (CIPN). Specifically, her investigations center around the identification of key pathways involved in this condition.

One significant finding from her team’s work is the activation of a crucial pathway in the skin following treatment with paclitaxel, a chemotherapeutic agent known to induce CIPN. Dr. Rieger’s research has revealed that the mechanisms involved in CIPN share similarities with diabetic peripheral neuropathy. Therefore, the drug treatments currently developed by Dr. Rieger’s team for CIPN could potentially have broader applications for individuals with diabetic peripheral neuropathy.
