Funded Grants

Altmann, Lori; Ph.D.

Dr. Lori Altmann is Principal Investigator on an R21 grant from the National Institute of Aging examining “Language and executive function in Parkinson’s disease: Effects of dual tasks and exercise.” Dr. Altmann and her collaborator, Dr. Chris J. Hass, PhD (Applied Physiology and Kinesiology) are comparing the effects of two different types of exercise, aerobic training or strength and balance training, on language production and cognitive performances in individuals with Parkinson’s disease. To mimic real world situations in which multi-tasking is the rule rather than the exception, language and cognition are assessed under dual task conditions. The goals of this research are to determine 1) whether exercise can improve cognition in individuals with Parkinson’s disease as it does in healthy older adults, 2) whether ANY exercise will lead to improvements in cognition and language production, 3) whether exercise can improve language production deficits in Parkinson’s disease, and 4) whether any improvements in language production following the exercise intervention are due to concomitant improvements in cognition. Other collaborators on this grant include Dr. Michael Okun. M.D. (Neurology), Dr. Joe Nocera, Ph.D. (VA; Institute on Aging), Dr. Dawn Bowers Ph.D. (Clinical and Health Psychology), Dr. Christine Sapienza Ph.D. (SLHS). Dr. Altmann joined the faculty in Fall 2003.

Crary, Michael A.; Ph.D.

Dr. Crary is the Co-PI on two grants with Dr. Giselle Carnaby-Mann from the Department of Behavioral Science and Community Health. The first grant is from the American Cancer Society and the project is a randomized clinical trial evaluating a program of swallowing intervention completed during the course or radiotherapy intervention for patients with head/neck cancer. The second grant is from the NIH (R21) and the project is a randomized clinical trial evaluating a dysphagia intervention with adjunctive NMES during rehabilitation for stroke survivors. Dr. Crary is the PI on a project funded by the CTSI at the University of Florida entitled ‘Development and Initial Validation of a Swallow Frequency Meter’.

Edmonds, Lisa; Ph.D.

Dr. Lisa Edmonds is the Principal Investigator for a Multicultural Grant from the American Speech Language and Hearing Association. The grant is entitled “Bilingual performance on An Object and Action Naming Battery: Preliminary normative data in Spanish and English.” The aim of this study is to collect normative data on An Object and Action Naming Battery, a naming test for persons with aphasia, on Spanish/English bilingual adults aged 18-40. The participants’ naming performance in both languages will then be correlated to demographic, language background and language use background to determine variables related to naming proficiency across languages.  

LePrell, Colleen; Ph.D.

One of the major research goals in Dr. Colleen Le Prell’s laboratory is the development of novel therapeutics to protect the inner ear against environmental insult. Dr. Le Prell is the Principal Investigator on an Opportunity Award Program grant from the University of Florida Office of Research (project period: 7/1/08-6/30/10). This grant, “A New Therapeutic for Prevention of Noise-Induced Hearing Loss,” explores mechanisms of noise-induced cell death and extends our understanding of antioxidant-mediated protection. These basic science studies investigating mechanisms of protection are actively being translated to man. Dr. Le Prell is a Co-Investigator on National Institute on Deafness and Other Communication Disorders (NIH/NIDCD) U01 DC 008423, Micronutrient Intervention to Reduce Noise-Induced Hearing Loss (PI: Josef Miller, University of Michigan; Project period 12/01/07-11/30/2011). She is directing laboratory-based human clinical trials at the University of Florida, and coordinating clinical trials conducted at three additional international study sites in Sweden and Spain. As part of this overall program, Dr. Le Prell has partnered with OtoMedicine, Inc. on two NIH/NIDCD Phase I Small Business Innovation Research (SBIR) projects (SBIR 1 R43 DC008710; SBIR 1 R43 DC009106), and funding for a new Phase II SBIR is pending.

In a second major research program, Dr. Le Prell is actively investigating the role of the lateral olivocochlear efferent system in perception of acoustic signals. She recently completed her role as Principal Investigator on NIH-NIDCD R03 DC 007342, “Functional Role of CGRP as an Efferent Neurotransmitter” (project period 7/1/05-6/30/08: $50,000 annual direct costs). Dr. Le Prell is extending these studies as Co-Investigator on NIH/NIDCD R01 DC 008131, “Physiological and Behavioral Assessment of Lateral Efferent Function” (PI: Richard Altschuler, University of Michigan; project period 7/1/07-6/30/12). She is directing psychophysical studies in her lab at the University of Florida that will identify the effects of lateral efferent disruption on the discrimination of acoustic signals.

Colleen joined the faculty of the University of Florida in August, 2007.

Logan, Kenneth J.; Ph.D.

Dr. Kenneth J. Logan is Principal Investigator on a newly funded grant from the Janus Development Corporation. The project will run for 2 years. Dr. Logan will be studying the effects of concurrent behavioral fluency therapy upon stuttering treatment outcomes in people who use the SpeechEasy® device. Adolescents and adults who stutter will be randomly assigned to treatments that feature either the SpeechEasy device in isolation or the SpeechEasy device in combination with a fluency shaping treatment that involves articulation rate management. Effects of clinician- and self-directed training will be assessed as well. Following a 10-week active treatment phase, participants will be tracked for up to 6 months to determine the extent to which treatment effects are maintained. Outcomes will be assessed using measures of stuttering severity, speech naturalness, communication attitudes, and quality of life. The predictive value of various pre-treatment variables for eventual treatment outcomes will be assessed as well.

Reilly, Jamie; Ph.D.

Dr. Jamie Reilly is the Principal Investigator on a K23 mentored patient-oriented career development award from the National Institute on Deafness and Other Communication Disorders (NIH/NIDCD), titled Structure of Semantic Memory in Dementia and Aphasia (Project period 2009-2014; total costs $861,000). In addition, Dr. Reilly is currently completing two additional NIH-NIDCD subcontracts respectively investigating lexical retrieval in semantic dementia (PI is Nadine Martin, Ph.D., Temple University) and developing a scale of fluency in aphasia (PI is Bruce Crosson, Ph.D.). In addition to these federal grants, Dr. Reilly is recipient of the 2008 NIH Clinical Loan Repayment Program, and he has two pending foundation grants to support his work on semantic memory and learning in dementia. Jamie joined the faculty of the University of Florida in August, 2007.

Sapienza, Christine; Ph.D.

Dr. Sapienza was recently funded (2010-2014) by the NIH/NIDCD R21/R33 to examine strategies to enhance the screening of airway protective behaviors in patients with neurodegenerative disease. She is collaborating with Dr. Giselle Mann from the Department of Behavioral and Community Health.

Dr. Christine Sapienza is a Principal Investigator on a newly funded VA Merit Review Grant which will be studying the effects of expiratory muscle strength training in persons with neurodegenerative disease including those with multiple sclerosis and Parkinson’s disease. The grant will have two phases, one in which the participants will be randomly enrolled in 5 weeks of expiratory muscle strength training or in a placebo training group. Following this phase a caregiver program will be tracked up to a 2 year period to determine if the effects can be maintained via caregiver support modules. Three different caregiver modules will be randomly tested.  The project will run for 4 years.
