A Fellowship for Future Discoveries

Alzheimer’s disease is one of the fastest growing threats to Americans’ health, but University of Iowa researchers like Guanghao “Max” Liu—a neuroscience graduate student within the Medical Scientist Training Program (MD/PhD)—are determined to discover the mechanism that causes this debilitating neurodegenerative disease.

In collaboration with Gloria Lee, MD, a professor of internal medicine at the Roy J. and Lucille A. Carver College of Medicine, Liu is studying the function of tau, a protein, in the healthy brain and how it interacts with other proteins. “In patients with Alzheimer’s disease, tau forms neurofibrillary tangles, which cause neuronal death and memory loss,” says Liu. “My goal is to find a therapeutic intervention involving tau, and ultimately, slow down and prevent Alzheimer’s disease progression.”

Tau and beta-amyloid peptides—which form plaques and tangles that are considered informative predictors of Alzheimer’s disease—change how the brain works many years before the first sign of memory loss. For the more than five million Americans living with Alzheimer’s disease, recent research on tau provides hope that breakthroughs may be on the horizon. Assisting Liu in his discoveries is the recently established Kwak-Ferguson Fellowship. Liu is the first recipient of the award, which is helping him advance his research, travel to conferences, and meet with other scientists in the field.

“We are facing an enormous increase in the number of people afflicted by conditions like Alzheimer’s disease,” says Dan Tranel, the head of the UI neuroscience graduate program. “Investments in research, like the Kwak-Ferguson Fellowship, continue to transform the understanding, prevention, detection, and treatment of Alzheimer’s disease and other neurological disorders.”

The Kwak-Ferguson Fellowship was established by Donald Timm (73JD), a Muscatine, Iowa, native who spent more than 30 years working for the U.S. Department of Defense as an expert on international law. He created the fellowship in honor of two individuals—his friend and mentor, Mr. Myung-Duk Kwak, a Korean attorney and statesman, and his aunt, Louis A.M. (Amelia Marie) Brown Ferguson, an educator and missionary—both of whom died due to complications from Parkinson’s disease.

Timm also says he was motivated, in large part, by the Roy J. Carver Charitable Trust’s gift to establish the Iowa Neuroscience Institute at the University of Iowa, which is developing new treatments for neurodegenerative disorders, including Alzheimer’s disease and Parkinson’s disease.

“Parkinson’s disease is truly a horrible disease, since the individuals suffering retain their intellectual capability but find it increasingly difficult to communicate their insights and feelings,” says Timm. “This seemed to be a perfect opportunity to help fight Parkinson’s and other diseases such as Alzheimer’s.”

For Liu, the fellowship is helping him become an even better physician-scientist and writer. “Because of the Iowa Neuroscience Institute and the Kwak-Ferguson Fellowship, I am ready to tackle any challenge in the future,” says Liu.
