Dr. Tianying Cai is an Assistant Professor of Human Development and Family Science at Auburn University. Her research examines how social environments shape adolescent neurophysiology and well-being, with a focus on family and neighborhood contexts. She uses fNIRS and physiological methods to understand brain-behavior relationships during the critical window of adolescence.
Outside the lab, Tianying can usually be found working, reading, or chatting with friends at her favorite local coffee shop, Side Track, where she also runs a mini coffee social group. She enjoys running, baking, and traveling to experience different cultures.

My name is Janishi Hightower, and I am entering the HDFS graduate program in the Fall of 2026. I am a former educator with additional certification in early intervention for children from birth through age five. I also previously ran a business designing and creating developmentally informed learning materials for infants and toddlers. Through these experiences, I became increasingly interested in understanding developmental trajectories and the ways life experiences shape them across the life course. I am particularly interested in how adverse experiences, such as poverty and chronic stress, can impact neural and physiological development and, in turn, shape life outcomes. Using fNIRS, I hope to explore the parent-child relationship and the potential buffering effects positive parent-child interactions may have for children experiencing chronic stress. Outside of my academic interests, I enjoy spending time with my husband and three children, hiking, visiting the panhandle, and exploring restaurants and shows in Atlanta.

I am a first-year graduate student in the Human Development and Family Science program at Auburn University. My research interests include computational neuroimaging, theoretical statistics, and methodology development, with a secondary interest in astrophysics. I previously worked as a student therapist and brought three years of clinical experience to my dynamic research background. In my free time, I like to watch scary movies, paint, play video games, and go hiking. I plan to adopt a bunny in the future.

My name is Cala Walker, and I am a Junior majoring in Biomedical Sciences on the Pre-Dental track from Birmingham, Alabama. I am interested in psychology and neuroscience, particularly how brain activity influences behavior, perception, and decision-making. Through my involvement in the CONNECT Lab, I have been able to explore these interests through hands-on research, strengthening my appreciation for evidence-based science and the connection between cognition and behavior. In the future, I plan to attend dental school and pursue a career in dentistry. Outside of academics and research, I enjoy working out and spending time with friends and family.

I am a Biomedical Sciences major at Auburn University from Trussville, Alabama, currently pursuing the Pre-Anesthesiologist Assistant track. My academic interests focus on neuroscience, human physiology, and the relationship between brain activity and behavior. As part of the research team, I work on projects using fNIRS to study how different activities, emotions, and thought processes influence brain activity. Our team aims to gain a deeper understanding of how specific mental states and behaviors trigger neural responses. Outside of academics and research, I enjoy going to the gym, reading, watching sports, and spending time with friends.

My name is Andrew Battenberg, and I was raised in Enterprise, Alabama. I am majoring in Biomedical Sciences on the Pre-Dental track. My classes have given me a strong background in biology and chemistry, and they have helped grow my interest in how the human body works. I am especially interested in neuroscience and how the brain controls what we think, feel, and see. In our research, we use fNIRS to study brain activity — measuring changes in blood oxygen levels while someone is doing a task to see which parts of the brain are active. In my life, I have learned that we know only what we perceive. On a personal level, I love to travel, swim at the beach, and experience new cultures.

I am a junior at Auburn University studying Biomedical Sciences in the College of Sciences and Mathematics on the pre-dental track. Originally from Raleigh, North Carolina, I plan to attend dental school after completing my undergraduate studies. As an undergraduate researcher in CONNECT Lab, I hope to gain a deeper understanding of how brain development, behavior, and environmental contexts interact to shape human development. Outside of academics and research, I enjoy spending time with my friends, going to the beach, and traveling.

I am a junior at Auburn University from Atlanta, Georgia, studying Psychology with a special interest in Artificial Intelligence and Industrial-Organizational (I/O) Psychology. I plan to complete a master's degree in I/O Psychology at Auburn and am excited to work in CONNECT Lab as an undergraduate research assistant to learn more about brain function and decision-making through fNIRS technology. I intend to apply my research experience to I/O Psychology by exploring education and workplace dynamics while gaining a deeper understanding of human development. I look forward to gaining new experiences that will support my future career in I/O Psychology.
