About Us


Chandra A. Reynolds

Chandra A. Reynolds

[Ph.D., University of Southern California, 1994]

Dr. Reynolds is currently a Professor of Psychology at UCR. 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

Anqing Zheng is a postdoctoral fellow recipient 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.


Shandell Pahlen

Shandell Pahlen

Shandell Pahlen is completing her dissertation on the influence of smoking behavior on cognitive functioning approaching midlife. She is an affiliate graduate researcher 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.

Tina Vo

Tina Vo

Tina is a fourth-year graduate student in the Biobehavioral Research Lab under the direction of Dr. Chandra Reynolds. She is interested in examining the gene and environmental interplay between sleep (duration and quality) and cognition and additional differential effects due to age, health, and SES. She is continuing her work with the consortium on the Interplay of Genes and Environment across Multiple Studies (IGEMS) to examine sleep as a moderator of cognitive aging. In Tina’s free time, she enjoys baking, going to Disneyland, and spoiling her pet bunny.

Subsequently, she served as a Postdoctoral Scholar in the Department of Psychiatry at the University of Pittsburgh. Since 2019 she has been Assistant Professor, Social and Health Psychology, at North Dakota State University.

Faredun Dungore
Faredun (Fred) was the previous Lab Manager for Dr. Reynold’s Lab. He graduated with his Bachelor’s Degree in Neuroscience from the University of California Riverside. He is currently attending the Western University of Health Sciences with the goal of becoming a Neurosurgeon.
