Bimonte-Nelson Lab - Our Team
Dr. Heather Bimonte-Nelson, Principal Investigator and Laboratory Director

My undergraduate degree in Psychology was earned at Richard Stockton College, located near the beach in Pomona, NJ. To follow my interests in brain and behavior, I began my doctoral research under the mentorship of Dr. Victor Denenberg at the University of Connecticut. My doctoral research focused upon sex differences in brain morphology and function in the rodent, and how ovarian hormones affected the expression of sex differences in an activational and organizational fashion. The idea that gonadal hormones could have such a profound influence on the brain and behavior was intriguing to me, and this area of work became my passion. After earning my Ph.D. in 2000, I started my postdoctoral fellowship with Dr. Ann-Charlotte Granholm at the University of Colorado Health Sciences Center in Denver, and several months later I helped move the laboratory to the Medical University of South Carolina. In a series of studies we found that aged male and female rats exhibited poorer working and reference memory relative to young rats, an effect that correlated with cortical neurotrophin levels. Soon after beginning my postdoctoral fellowship I also started investigating gonadal hormone effects on cognition and neurotrophins during aging in the rodent.
Collectively, our initial as well as our current findings demonstrate that estrogen and progesterone have divergent effects on memory and neurobiology in aging females. We also have newer data suggesting that the memory effects of ovarian hormone loss and replacement depend on age. Using the rodent model, we are currently testing the cognitive and neurobiological effects of hormones used by women in the clinic, such as Premarin and MPA. These complex interactive relationships between hormones, aging, and memory are a large thrust of our current work here at ASU, which began when the Bimonte-Nelson Memory and Aging Laboratory was initiated in June of 2005. We are also interested in non-pharmacological approaches to protecting the brain and cognition against age-related change. I am thrilled that recently I received tenure with promotion to Associate Professor, here at ASU. When I am not in the laboratory or teaching, I enjoy the beautiful Arizona atmosphere by spending time outdoors with my husband, Matt, and our two young daughters, Hailey and Brooke. I also enjoy painting, music, concerts and writing short stories.
Candy Tsang (BS), Laboratory Manager
I graduated from Washington High School for the year 2007 in the top 10% in Phoenix, Arizona. I was selected to join the SOLUR (School of Life Sciences Undergraduate Research) program as an apprentice in the College of Liberal Arts and Sciences. I was matched up by the SOLUR program to work with Dr. Heather Bimonte-Nelson, in order to study the effects of ovarian hormones and aging on cognition. I have just graduated Arizona State University (2011), majoring in microbiology and minoring in psychology. I have been in the Bimonte-Nelson laboratory for five years. Next year, I hope to enter medical school.
Jazmin Acosta (PhD), Postdoctoral Fellow
As an undergraduate, I attended the City University of New York where I majored in Psychology. After taking an undergraduate class in Physiological Psychology, I was invited to join a team of researchers at the New York University Hospital where I worked with Alzheimer's patients administering a battery of neuropsychological tests. I also worked with Dr. Richard Bodnar examining central opioid receptor systems and pain-inhibition as an undergraduate. As a doctoral student at Arizona State University, I first worked with Dr. Neisewander investigating the role of specific serotonin receptor subtypes in incentive motivation for cocaine. I joined the Bimonte-Nelson laboratory two years ago to pursue my passion of studying the effects of ovarian hormones on cognition, age-related cognitive decline and neurodegenerative diseases such as Alzheimer's disease. On August 21st, 2009, I defended my dissertation, and completed the doctoral program in the Behavioral Neuroscience program in the ASU Psychology department. My dissertation work was done in the Bimonte-Nelson laboratory, studying how etiology of menopause and hormone therapy impacts cognition in the animal model. I am now a postdoctoral fellow in the lab studying novel models of menopause, and associated interactions with clinically-used hormone therapies.
Joshua Talboom (MA), Graduate Student
I attended Fruita Monument High School in Grand Junction Colorado, where I also attended college at Mesa State. I received my BA in psychology with a minor in biology. My undergraduate experience was diverse as I participated in a few performing arts, was the president of the local Psi Chi chapter, and conducted semi-independent research. In my undergraduate research, I examined why humans gossip as well as the prenatal effects of cocaine on the cerebral ventricles in mice. I am currently a 5th year PhD student within the Behavioral Neuroscience program at ASU. My current interests include discovering the molecular mechanisms that underlie memory and aging, as well as how hormones interact with age to affect memory.
Liz Engler (MA), Graduate Student
I am originally from southern California and graduated from Thousand Oaks High School. I attended Arizona State University as an undergrad and earned a BS in Psychology with honors from Barrett, the Honors College, minoring in Spanish. As a member of the Solur Researcher program, I began working with Dr. Bimonte-Nelson in March of 2006 to start work on my senior honors thesis project. This study investigated the effects of ovariectomy at different timepoints during aging in the female rat on water radial arm and Morris maze performance. I spent a semester studying language in Granada, Spain and volunteered for a medical outreach excursion to Costa Rica and Nicaragua, where I served as a student clinician and interpreter. Currently, I am beginning my fourth year in the lab. My research interests include changes in cognition associated with aging, the effects of ovarian hormone loss and changes in other gonadotropins on spatial behavior, and Alzheimer's Disease.
Blair Braden (MA), Graduate Student
I am originally from Frankfort Kentucky and recently graduated from the University of Kentucky in Lexington. I received my BS in psychology with honors and a minor in mathematics. In my undergraduate research I completed an honors thesis on the individual and combined effects of alcohol and the HIV protein tat on hippocampal cell tissue cultures. I was a member of Psi Chi and also participated in a wide variety of community service and intramural athletics. I am currently beginning my fourth year of graduate school. My current interest focuses on the molecular mechanism that underlie hormonal effects on memory and cognition, as well as neurodegenerative diseases such as Alzheimer's disease.
