Marina Kogan

Assistant Professor, School of Computing, University of Utah

Marina Kogan works at the intersection of data science and human-centered computing. She develops human-centered data science (HCDS) methods that in addition to their scalability account for the highly-contextual nature of social activity in online environments. As Kogan also works in the area of Crisis Informatics, context-sensitive methods are especially important to her safety-critical application domain. In 2022, she co-authored Human-Centered Data Science, an introductory textbook to for the emerging HCDS field. Kogan often employed the lens of complex adaptive systems to model and understand group behavior on online platforms. The complex systems perspective allows her to trace and model how individual behaviors “add up” to the collective social dynamics.

Elliot H Smith

Assistant Professor, Neurosurgery Department, University of Utah

My research focuses on representation and computation in ensembles of human brain cells. The basic motivating question is “what are the neural computations that underlie archetypically human cognitive processes and how are they altered in neurological or psychiatric disorders?” The cognitive processes I am most interested in are value-based choices, rapid flexible cognitive control, and social cognition. In order to understand these processes underlying human cognition, we record from the brains of neurosurgical patients who are undergoing monitoring in order to diagnose and treat neurological disorders such as Epilepsy and Parkinson’s Disease. In the process, we generate some of the largest datasets in neuroscience.

Adjunct Professor, Biomedical Informatics, University of Utah

I am a biodemographer interested in familial aspects of health, aging and longevity. Currently I am investigating the socio-environmental and genetic origins of rates of aging in humans and exceptional longevity in families. The purpose of this work is to determine how overall aging may be a key factor in determining the risks of multiple major causes of disease associated with age and to identify genes and gene-environment interactions affecting exceptional human longevity. This area of research also focuses on the associations between life history traits, primarily fertility and longevity. My current work examines the role of early life events and how they affect life chances and health outcomes of middle-aged and older adults. My other key research interests focus on psychosocial and behavioral factors in cancer prevention and control and the effects of family, community, and socioeconomic factors affecting health outcomes, obesity, mortality, and longevity of individuals.
