COLLEGE OF HEALTH SCIENCES UNDERGRADUATE SUMMER RESEARCH PROGRAM STUDENT RESEARCH DAY

JULY 26 9:30am- 3:00pm in Cramer Hall 016

The College of Health Sciences Summer Research Program is a highly competitive program that offers undergraduate students the opportunity to learn first-hand about biomedical research through an intensive 10-wk experience in which they receive a stipend to work in the laboratory of a faculty mentor.

This yearís program consists of 36 students working in the laboratories of 19 faculty mentors from five academic departments/programs in the College of Health Sciences. Since it was established in 2003, more than 200 students have participated in the program. Almost all of these students have entered into careers as researchers or health professionals.

The program is unique in that it almost exclusively provides opportunity to Marquette students, often allowing them to have a continuous year-round involvement in research. By participating in high-level science aimed at addressing some of societyís most pressing medical issues, students are provided with a truly powerful and transformative educational experience.

The program culminates with a poster-session that will be held in on July 26th at which students will present their research findings and is open to the public.

Examples of student research projects that are part of this yearís program include the following:

Abigail Nelezen, Laboratory of Dr. Paul Gasser, Biomedical Sciences.

Abigail is a junior in Department of Biomedical Sciences and a pre-med student.

Project Title: Mechanisms underlying enhanced memory for stressful life events

Post-traumatic stress disorder (PTSD) is a debilitating condition with high prevalence among military veterans, first responders, and victims of abuse. These studies are examining the mechanisms by which stressful life events alter brain function, specifically memory processing in a way that can lead to PTSD. The hope is that understanding these mechanisms may lead to the development of new treatments for the management of PTSD

Andre Jacobson; Laboratories of Dr. John Mantsch and Bob Wheeler, Department of Biomedical Sciences.

Andre is a junior in the Department of Biomedical Sciences and a pre-med student.

Project Title: Effects aversive stimuli on dopamine signaling and cocaine use

The societal burden of drug addiction is tremendous and fundamental gaps in our understanding of the underlying neuropathology have hindered the development of effective treatments. These studies are using a cutting edge electrochemical detection technique to measure changes in the levels of the neurotransmitter dopamine in brain regions implicated in motivation and addiction with the goal of understanding the neurobiological processes that lead to the relapse of drug use in addicts.

Anna Buzzard; Laboratory of Dr. Sandra Hunter, Department of Physical Therapy.

Anna is a junior in the Program in Exercise Physiology and a pre-PT student.

Project Title: Muscle function and fatigue with type 2 diabetes

Diabetes is a chronic metabolic disease that is a global pandemic of rising prevalence: one in three people born in 2000 will develop Type 2 diabetes mellitus. People with type 2 diabetes often suffer from excessive fatigue and often-neglected neuromuscular symptoms that include muscle weakness and pain. This study will expose the cause of exacerbated fatigue in people with type 2 diabetes by examining the origins of physical fatigue within the brain and the muscle during fatiguing contractions of the legs. Understanding the origins of fatigue is the first step to developing targeted strategies to offset fatigue in men and women with type 2 diabetes.

Rachael Hefel; Laboratory of Dr. Jeff Berry, Department of Speech Pathology and Audiology.

Rachael is a student in the SPPA program

Project Title: Acoustic effects on speech sensorimotor learning

Talkers involuntarily alter the movements of their tongue, lip, and jaw movements when subtle acoustic features of their speech are modified digitally to affect how they perceive their own speech. These altered movements can persist even after the acoustic modifications are stopped, suggesting novel, short term sensorimotor relearning of speech articulation. Students in the Speech and Swallowing Lab are studying how different acoustic parameters interact in creating these effects by manipulating the perceived pitch of a talkerís voice, the resonances of their vowel sounds, and examining learning effects for vowel sounds when they occur following different types of consonant sounds. The results of these experiments will inform us about of speech learning is impacted by sensorimotor integration and provide insights that may bolster improved methods for rehabilitating acquired speech disorders.
