Hannah has worked in my lab since summer 2015 (the summer after her freshman year). Her work began with the bare-bones setup of a video camera and a social cage with five mice. After countless hours of scoring CCTV videos of mouse interactions, she has developed her own study to explore the influence of social rank on anxiotypic behavior and BDNF expression in the BNST. Her study incorporates both male and female mice and probes potential sex differences in the effects of social stress on physiology and behavior. She observed passive avoidance behavior (using a light-dark box) and open field behavior in male and female mice to determine if social rank (measured by home cage aggression and the tube test) has an effect on anxiety-like behavior in mice . To understand the physiological changes that may underlie these changes in behavior, she developed and performed a qPCR assay to measure BDNF expression in the BNST.
Hannah's work was presented at multiple local and international conferences, and she received multiple awards and recognition for her presentations.
Hannah is currently working under a fellowship award at the Medical Research Institute for Chemical Defense in Aberdeen, MD.
Emily took on the daunting task of completing a conceptual project as part of her senior thesis with my laboratory. Her project entailed building (from scratch) a touchscreen operant system for rats, built on an Arduino platform. To do this, she engaged her peers and incorporated two computer science majors to help her complete her project. With these two students, she developed the hardware and software needed for this system, and implemented it in a pilot project using four female Long-Evans rats.
These rats were successfully trained on a simple FR1 (fixed ratio one - one touch of the screen earned a sugar pellet reward) task. This system is currently being refined to be as an 'in-home-cage' device to be used with our RFID gated system.
Emily's work was completed, in part, thanks to the Piscopo Research Fellowship. Upon graduation, Emily earned the prestigious Castle Award by the UMW Department of Biological Sciences for her dedication and excellent performance as a well rounded student in biology. She is currently traveling the world, and intends to seek a career in neuropharmacology upon completing her well-deserved, soul-searching adventures.
Meagan Darling was the first undergraduate student to join my laboratory. She had the distinct honor of piloting out many of the crazy ideas I had to record and investigate social behavior in mice, as well as some more sane ideas of her own.
Meagan completed an investigation of mouse social behavior, and the neural systems that guide this behavior. She performed this work across multiple laboratories, working under the advisement of Dr. Ken Renner at the University of South Dakota, and Dr. David Coppola at Randolph Macon College. Being the first student to work in my laboratory, she endured a bare-bones environment, but was still able to generate valuable data, which led to multiple published abstracts and impactful results. Her work also jumpstarted ideas that have led to many other project which are being performed by students currently working in my lab.
Meagan is currently enjoying a successful career as a Clinical Research Coordinator in the Cancer Center at the University of Viriginia.
Alex Piercy completed a project that examined senescent cognitive decline using a mouse model of environmental enrichment. We attached a Lashley-Type maze to the home cage of our mice (22 week old female CD-1 mice) that they had to navigate to access their food hopper. Using RFID tracking, we recorded their movement through this maze and changed the position of the food hopper once they had mastered navigating the maze. This presented a cognitively stimulating home living environment, which has been hypothesized to protect against age related cognitive decline in humans. We plan to measure levels of BDNF in the hippocampus of these mice using qPCR techniques.
Alex received a grant award from the Virginia Academy of Science, and presented her behavioral results at the annual meeting of this organization. She is currently pursuing a doctoral degree in pharmacy at the University of Delaware.
