Class of 2022 PI Millionaires

This year’s PI millionaires join their UofM colleagues in achieving this prestigious designation. More details can be found in the Research Celebration program.

Duane McKenna, Department of Biological Sciences Duanne Mckenna

Duane McKenna is the William D. Hill Professor of Biology in the Department of Biological Sciences at the University of Memphis. He studies insect systematics (diversification and relationships among species and higher taxa through time), genomics, and the ecology, evolution and genomic basis of insect-plant interactions. Other interests include chemical communication in insects and geographic patterns of insect diversity and endemism. Most of his research is focused on the order Coleoptera (beetles). Dr. McKenna's research program involves a combination of field, collections, and laboratory work, and has been supported by grants from the U.S. National Science Foundation, the U.S. Department of Agriculture, the U.S. Environmental Protection Agency, and other organizations. He is the founding Director of the University of Memphis Center for Biodiversity Research (CBio; www.umbiodiversity.org) and Director of the University of Memphis Agriculture and Food Technologies Research Cluster.

Helen Sable, Department of Psychology Helen Sable

Helen Sable, PhD is a professor and associate chair in the Department of Psychology at the University of Memphis (UofM). Dr. Sable’s research program spans the fields of behavioral neuroscience and neurotoxicology, with a central focus on examining neurobiological and environmental factors that contribute to externalizing behavior. There is inherent complexity in this approach because these factors often interact (e.g, gene-environment interactions). The results of her research inform government regulatory practices, aid in pharmacotherapy development, and contribute to the scientific literature on the etiology of externalizing disorders, particularly Attention-Deficit Hyperactivity Disorder (ADHD) and Substance Use Disorder (SUD). Additionally, Dr. Sable serves as an associate editor for the journal Neurotoxicology and Teratology, is a past president of the Developmental Neurotoxicology Society, and a previous recipient of the Patricia Rodier Mid-Career Award in Research and Mentoring.

REU Site: Memphis Neuroscience Techniques and Research Training Program (NeuroSTART)

H Sable and D Lester (co-PIs)

5/15/2021 – 5/14/2023; Total costs: $285,908

The goal of this project is to provide research experience and professional development skills to first-gen and underrepresented minority undergraduates to ensure they are more successful at securing admission to graduate neuroscience programs.

Role: Principal Investigator

Identifying the neurophysiological basis of risky decision-making

N Simon (PI)

7/1/2019-6/30/2023; Total costs: $395,791

The goal of this project is to determine the neurophysiological mechanisms that underlie pathological risky decision-making by using behavioral paradigms designed to evaluate the different stages decision-making, including evaluating pre-decision deliberation, the encoding process of consequences associated with a risky choice, and abnormal processing of rewarding and aversive events.

Role: Co-Investigator

Role: Co-Investigator


Assessment of Psychostimulant Addiction Risk Following Developmental PCB Exposure

H Sable (PI)

03/01/2009 – 11/30/2012; Total costs: $722,099
