Research Awards and Luncheon

David Zhi-Zhou He, MD, PhD, professor of biomedical sciences in the School of Medicine, and Maya Khanna, PhD, professor of psychological science in the College of Arts and Sciences have been named the 2023 Creighton University Research Award recipients.

The two will be recognized during the University Research Awards and Luncheon on Wednesday, March 29, in the Mike and Josie Harper Center, Room 2057/2058. This luncheon, from 11:30 a.m. to 1 p.m. CT, is open to all faculty, students, and staff. No registration is requried.

Recipients of the he Dr. and Mrs. Randolph Ferlic Undergraduate Mentor Award and the Dr. Robert Heaney Graduate Mentor Award will also be recognized.

David Zhi-Zhou He, MD, PhD

In his presentation, "Cochlear Hair Cells: Why Losing Them Leads to Hearing Loss," Dr. He shows how mutations of two genes, Slc7a14 (differentially expressed in IHCs) and Dnm3 (differentially expressed in OHCs), lead to hearing loss in mouse models and humans. 

Inner and outer hair cells (IHCs and OHCs) are the two types of mechanoreceptor cells in the mammalian cochlea of the inner ear that transduce mechanical stimuli into electrical activity. IHCs are the true sensory receptor cells that transmit auditory input to the brain. OHCs are a mammalian innovation with a unique capability to change length in response to changes in receptor potential. Using RNA-seq analysis of adult mouse cochleae, He identifies genes that are differentially expressed in these two cell types.

He and his team's goal was to characterize genes underlying the unique structure and function of IHCs and OHCs and to determine if mutations of the gene will lead to hearing loss in animals and humans. They employed a variety of in vitro and in vivo experimental techniques including electrophysiology (system and cellular), immunocytochemistry, advanced imaging, mouse genetics and molecular biology.

Maya Khanna, PhD

In her presentation, "It’s the word, nerd: Using words to explore memory, attention, spelling, concept representation, and development," Dr. Khanna shares her research in cognition that focuses on her favorite topic, words, and highlight her research on word-processing.

Khanna shares how word features, such as their meanings, sounds and spelling patterns, influence the way that words are remembered and how people pay attention to words in specific contexts. Her examinations of how these semantic (i.e., meaning-based) and sub-lexical (e.g., spelling and sound) features influence word processing in both children and adults in a wide range of behaviors. Behaviors include reading aloud, spelling, meaning selection of ambiguous words (e.g., bark), word learning, attention allocation during word processing, and the formation of true and false memories of words.
