About Us

Chandra A. Reynolds (chandra.reynolds@colorado.edu)
[Ph.D., University of Southern California, 1994]
Chandra Reynolds is currently a Professor at the Institute for Behavioral Genetics and the Department of Psychology & Neuroscience at the University of Colorado Boulder and is a Professor Emerita of Psychology at University of California Riverside. Her research interests center around the interrelationships between health and cognition across development. She directs projects that consider the genetic and environmental etiologies of cognitive aging, including gene pathways and their possible interaction with environmental factors. Additional projects include examinations of early life factors and contexts that influence cognitive, physical health and well-being profiles into early adulthood and across the lifespan.

Anqing Zheng (anqing.zheng@colorado.edu)
Anqing Zheng is a postdoctoral researcher in the BBR lab. Her primary interest concerns the ways genetically influenced characteristics combine and interact with the environment to guide each person’s psychological characteristics (i.e., personality, socio-emotional skills, cognitive ability). She is also interested in representing dynamic relations among psychological variables, as well as the antecedents and causes of those variables. She prefers to approach these issues using large representative datasets and meta-analyses and embraces the opportunities brought by big data and machine learning paradigms. In Anqing’s spare time, she is a big fan of skiing, leisure snowboarding, occasional indoor climbing, and pouring love to her (slightly) psychopathy cat.

Tara Henechowicz
Research Interests:
My primary research interests focus on understanding the etiology of Alzheimer’s disease and related dementias across the lifespan, particularly how modifiable risk factors interact with genetic risk. Currently, I am investigating the causal associations between modifiable risk factors and dementia using multidisciplinary methodologies. I have extensive training in statistical genomics, supported by doctoral fellowships from the Canadian Statistical Sciences Institute and the University of Toronto Data Science Institute.
In parallel, I am involved in the international Musicality Genomics Consortium, which investigates the genetic underpinnings of musicality, that is, musical behaviors such as playing a musical instrument, singing engagement, and skills like rhythm and music perception. I am also interested in exploring the associations between musicality and health, as well as the complex interplay between genetic and environmental factors that shape these relationships.

Sarah Carroll
I am interested in the application of the twin design and other behavioral genetic methods to understand the factors that give rise to youth mental health trajectories.

Shandell Pahlen (shandell.pahlen@colorado.edu)
Shandell Pahlen is a postdoctoral researcher at CU Boulder, after having completed her dissertation on the influence of smoking behavior on cognitive functioning approaching midlife at UCR. She has contributed to projects for the consortium on the Interplay of Genes and Environment across Multiple Studies (IGEMS) and the Colorado Adoption/Twin Study of Lifespan (CATSLife). Shandell’s research focuses on examining how smoking control policies and smoking behaviors impact the developmental trajectories of cognition functioning across the lifespan. Further, she is interested in exploring how smoking behavior and socioeconomic status influence the etiology of cognitive functioning via behavior genetic designs.

Alex Sheppard (Alex.Sheppard@colorado.edu)
Nicole Menis
Nicole is a first-year graduate student in the Clinical Psychology program at the University of Colorado Boulder. Her research interests include the neuropsychological aspects of cognitive aging and how experiences across the lifespan contribute to resilience and healthy aging. In her free time, she enjoys crocheting, hiking, attending trivia nights, and spending time with her cat.

Claudia Paniagua-Ugarte
My research focuses on understanding how cognitive abilities change and develop across the lifespan, and how genetics and life experiences work together to shape these trajectories. I am especially interested in identifying early markers of both risk and resilience, with the goal of supporting earlier and more meaningful approaches to promoting healthy cognitive aging and overall well-being. Outside of research, I enjoy spending time outdoors hiking, trail running, and exploring new places. I also enjoy discovering different cuisines.

Ashley Barrows
Ashley is a first-year graduate student in the Behavioral, Psychiatric, and Statistical Genetics program at the University of Colorado Boulder. Her research explores early- and mid-life influences on cognitive aging and how genetic and environmental factors mediate or moderate their effects. In her free time, she enjoys reading, cooking, and hiking.
