More About the Team

Lance A. Johnson, Ph.D.
Associate Professor
Principal Investigator
@LJohnsonLab
Lance grew up in Asheville, NC and attended the University of North Carolina for both his undergraduate and graduate studies. He completed his PhD in the prestigious joint laboratory of Excellence Professor Nobuyo Maeda and Nobel Laureate Oliver Smithies. Under their exceptional guidance, Lance studied how the various isoforms of apolipoprotein E (APOE) affected atherosclerotic plaque development. Fascinated by advances in neuroscience and intrigued by the role of ApoE in the brain, Lance secured a position as a NIH-funded Postdoctoral Fellow at Oregon Health & Science University, in beautiful Portland, OR. Under the mentorship of Professor Jacob Raber, he investigated the role of ApoE in metabolism and cognitive function, and explored the mechanisms underlying insulin resistance-associated cerebrovascular dysfunction and recovery. Lance joined the Department of Physiology and Sanders Brown Center on Aging at the University of Kentucky in December 2016. In addition to tinkering around in the lab, Lance loves spending time with his wife and kids, being outdoors, cooking, and playing basketball (poorly).

Nick Devanney
Ph.D. Candidate
Nick graduated with a Bachelor's degree in Biochemistry from the University of New Hampshire, where he pursued undergraduate research with Dr. Win Watson (studying circadian rhythms) and an honors thesis in the laboratory of Dr. Charles Walker (studying p53 and mortalin in acute myeloid leukemia). After graduating, Nick spent 3 years as a research assistant with Dr. Basile Tarchini at The Jackson Laboratory in Bar Harbor, ME, studying developmental genetics of the sensory hair cells in the inner ear. Nick's project investigates the interplay of APOE’s influence on microglial metabolism with neuroinflammation in AD, a concept known as ‘immunometabolism’. The underlying hypothesis is that altered metabolic preference associated with APOE genotype is driving the detrimental inflammatory response in E4 individuals. Outside of the lab Nick is a musician and a nature enthusiast, spending his free time immersed in Lexington’s local music scene or hiking in nearby Red River Gorge.

Lesley Golden
Ph.D. Candidate
Lesley grew up in St. Louis, MO and attended Murray State University where she graduated with a B.S. in Molecular Biology. During her undergraduate degree, Lesley studied transcription factors involved in the specification and maturation of pancreatic endocrine cells. She decided to pursue her PhD at the University of Kentucky and joined the lab in March of 2020. Lesley is interested in characterizing a novel mouse model and studying the effects of targeting APOE as a potential therapeutic for Alzheimer’s disease. Outside of the lab Lesley enjoys spending time with her horses, hiking, and snuggling her cats.

Steve MacLean
Ph.D. Student
Steve is from Beverly Hills, Michigan. He studied Neuroscience at Central Michigan University and graduated with his B.S. in 2019. After deciding that Michigan was too cold, Steve moved to Kentucky to work in Dr. John Gensel's lab studying spinal cord injury. After 2 years in Dr. Gensel's lab, he started the IBS program and joined Lance Johnson's lab. Steve is interested in Alzheimer's disease and neurodegeneration. Outside of the lab, Steve likes to play video games and be outside when it is sunny.

Akhil Pallerla
MD/Ph.D. Student
Akhil is from Cincinnati, OH and graduated from the University of Pittsburgh in December 2020 with a dual degree in Neuroscience and Economics. He is a rising second year medical student in the MD/PhD program at UK. He got his start in research working in Dr. Ed Dixon’s lab at Pitt studying animal modeling and therapeutic targets in traumatic brain injury. He is interested in some of the parallels between ApoE expression patterns in TBI and Alzheimer’s and will be studying markers of neuroinflammation in microglia during his rotation this summer. Outside of the lab, Akhil enjoys swimming, spending time outdoors, cooking, and traveling.

Dahlia Siano
Sophomore
Dahlia is from Glasgow, KY, and is now an undergraduate at the University of Kentucky pursuing a dual degree in neuroscience and psychology. Alzheimer's is what sparked her interest in neuroscience, and ever since then, she has been fascinated by the enigma that is the human brain. She found Dr. Johnson's lab and was immediately intrigued by the research being done, as she had never considered that a metabolic protein could have such a strong effect on the development of neurodegenerative disorders, such as Alzheimer's. She is excited to have the opportunity to learn more about Alzheimer's in a new light and to participate in research amongst so many amazing people. Alongside neurodegenerative disorders, she is also extremely interested in addiction and mental health disorders, so she hopes that being part of the lab will give her important exposure to the processes and techniques she needs to work in the lab, as well as help her find the path within neuroscience that she wishes to pursue. After her undergraduate, Dahlia plans to attend graduate school and pursue a career in research. In her free time, she enjoys hammocking, baking, and drawing.
