In addition, she is currently working as Associate Dean of Faculty Affairs in the University at Buffalo, College of Arts and Sciences. Kris completed her M.A. at the University of Minnesota and her Ph.D. at the University of Wisconsin-Madison in the area of Communicative Disorders & Sciences. The MSD lab conducts research investigating the acoustic bases of reduced intelligibility and naturalness in dysarthria secondary to neurodegenerative disease such as Parkinson’s disease and Multiple Sclerosis.<\/figcaption><\/figure>\n<\/div>\n

Annie Rohl, MS, CCC-SLP.\u00a0 \u00a0 \u00a0 \u00a0 \u00a0 \u00a0 <\/strong>Annie has an MS in Speech-Language Pathology at the University of Wisconsin\u2013Madison and worked as a speech-language pathologist for several years before returning to research. She completed her PhD in Neuroscience at the University of Iowa in 2026. Her research focuses on the neural control of speech production and the functional effects of Parkinson’s disease and brain stimulation on speech. With her interdisciplinary background, Annie is passionate about bridging the gap between basic and clinical science to improve the understanding and management of speech changes in neurodegenerative disease.<\/span><\/figcaption><\/figure>\n

After a brief clinical experience, however, she realized she was more interested in researching speech therapy than providing it. Thus, she pursued a PhD in Speech and Hearing Science at Ohio State. Her graduate training was primarily in acoustic analysis and indexical perception, and she’s especially fascinated by the lack of invariance problem. As a Wisconsin native, she may be new to Buffalo\u2014but certainly not to snow! In her free time, Lian enjoys coaching cross country, collecting interesting facts, and attempting to take personality quizzes on behalf of her dog.<\/figcaption><\/figure>\n
Jordan Manes, PhD<\/b><\/span>
Volunteer Research Assistant Professor<\/strong><\/h6>\n

Jordan completed her PhD in Systems & Cognitive Neuroscience at Northwestern University, specializing in movement and rehabilitation sciences. Her research utilizes acoustic speech measures and functional neuroimaging to better understand brain-behavior interactions associated with neurogenic motor speech disorders, such as Parkinson\u2019s disease.<\/span><\/p>\n
