Philosophy of Scholarship

Cellular and Molecular Neurobiology Research with Undergraduates at Agnes Scott

One of the exciting aspects of science is that scientific research can be made accessible to learners at various stages of their academic career. The engagement of students in scientific research not only enhances the project itself, but, it also enhances the educational experience of the students involved in the project, imparting critical thinking skills and a deeper understanding of neurobiology through a hands-on approach. For careers in science, students need the following skills which are can acquired in an inquiry based lab setting: 1. Ability to design an effective experiment, analyze the data with statistics, draw important conclusions, write a scientific report on the research and present the research. 2. Critically read scientific literature.3. Apply knowledge learned in order to solve a problem. 4. Work in pairs or teams utilizing leadership skills. 5. Communicate science effectively both written and orally. 

Through inquiry based research in my lab, students can acquire those necessary skills while we answer interesting questions about how vesicle trafficking impacts brain development and how alterations in that trafficking are implicated in neurodevelopmental disorders such as Autism Spectrum Disorders and Schizophrenia .My research supports several projects for students. Some examples are: How does a DNA modification affect molecules involved in neurodevelopment? What regulates vesicle trafficking within neurons? How do molecules affect animal/human behavior? And How do changes in neuronal cell populations impact neuronal development?

The scientific details of my research project can be found here. In short, we exploring the effects of loss of BLOC-1 subunits (a vesicle coat-associated protein complex) and interacting proteins on the excitatory/inhibitory (E/I) balance in the hippocampus. Loss of the BLOC-1 proteins results in alterations of endosomal trafficking and dendritic spine morphology as well as a change in the population of parvalbumin interneurons in the hippocampus. Our work continues to explore changes in cellular function when BLOC-1 is removed. This research is necessary as subunits of BLOC-1 and interacting proteins have been implicated in several neurodevelopmental disorders, such as Schizophrenia, Rett Syndrome, and Autism Spectrum Disorders. This research project incorporates transcriptional biology, behavioral analysis, primary cell cultures, confocal microscopy, biochemical techniques, and mouse genetics. With an observable phenotype, such as a disease model, my research project can increase student’s ability to transfer the science knowledge from lectures and data gained in each experiment to a greater understanding of what happens when neurons are not functioning properly.

Personal Lab Research

Research with students is such a high priority to me that even in my first semester, I worked with three students. From that semester forward, I have been working with students in my lab. During the week, I spend 4-6 hours with my research students in lab. Some of these students have been volunteers and some have been part of a Mentored Research class (BIO 440, BIO 380, BIO 410). Over my 5 years at Agnes Scott, I have worked with 24 students in my personal lab. The students who have participated in research in my lab and their final products can be viewed here.

Of those 24 students I have worked with:

  • 9 students are authors on a manuscripts, and 3 of those students are an author on 2 manuscripts
  • 2 students gave poster presentations in the main meeting at the annual Society for Neuroscience meeting
  • 1 student gave an oral presentation (nanosymposium) at the annual Society for Neuroscience meeting
  • 15 students gave an oral presentation at Agnes Scott's student research day, SpARC
  • 3 students gave a poster presentation at Agnes Scott's student research day, SpARC

During my 5 years at Agnes, I have published 9 peer-reviewed articles based on my research (article reference hyper links are found here) and research with my col. My research projects have generated four peer-reviewed primary articles and 1 peer-reviewed review article with students as co-authors on the paper. There are an additional 4 peer-reviewed primary articles published on collaborative projects with the Faundez lab at Emory and the Pozzo-Miller lab at UAB. 

From Research Students:

"I worked with Dr. Larimore identifying a common molecular pathway between Rett syndrome and schizophrenia for 3 semesters. I am in medical school, and I am currently applying for psychiatry residencies. Working with Dr. Larimore fostered my interest in neuroscience, mental health, and neurodevelopment disorders.  Through my research with Dr. Larimore and the classes I took with her, I was able to develop critical thinking skills and public speaking skills. " Alex Ambrose (Class of 2013)

"As a current doctoral candidate in the interdisciplinary program in neuroscience at Georgetown University, my work in Dr. Jennifer Larimore's lab during my senior year at ASC propelled my neuroscience graduate career. Together we have published 3 research manuscripts and 1 review, presented research at local and national conferences, and maintained a successful mentor and mentee relationship years after my graduation in 2014. The combination of Dr. Larimore's training both inside and outside the lab shaped my career in unprecedented ways. With her training, guidance, and recommendation letters I have won 3 research fellowships funded by NIH and Society for Neuroscience, 5 presentation awards from national conferences, and continued to build my neuroscience skill set at Georgetown. Without her mentorship, teaching abilities and infectious love of neuroscience - there is no way I would be the successful and productive member of the scientific community that I currently am. Her love of research has shaped my current career goals and future plans to enter academia teaching at a small college that focuses on training undergraduate students for graduate school. To date, Dr. Larimore remains my professional and personal role model, and her contributions to ASC's biology department and Neuroscience major have forever impacted the way I conduct research, mentor students, and succeed in science. Without a single doubt in my mind, I owe her all of my success and passion for neuroscience research to her and our time time together at ASC." Kaela Singleton (Class of 2014)

"My time in the Larimore lab has given me the tools to confidently pursue a career in neuroscience research. As well as gaining tangible skills such as western blotting, imaging, and cell culture, I also gained invaluable intangible skills such as critical thinking, problem-solving, and troubleshooting. It is due in no small part to Dr. Larimore, and my experience working in her lab for over 5 semesters, that I am more motivated and equipped than ever to be successful in my future research endeavors as I prepare to graduate in December of 2017." Hannah Rudolph (Class of 2018)

Fall 2012 - Spring 2013


During my first year at Agnes, with the support of an external grant from the International Rett Syndrome Foundation, I published a manuscript with a student (Laurel (Alex) Amrbose) examining the roles of the MeCP2, a gene that is implicated in Rett Syndrome, in synaptic expression of BLOC-1 subunits using animal models and human pluripotent stem cells. I was a co-author on a manuscript that was a result of my continued collaboration with Dr. Pozzo-Miller examining the TRPC signaling and BDNF release in the hippocampus of a Rett Syndrome mouse model. In my third publication that year, also in collaboration with Dr. Pozzo-Miller, we published a review on the recent progress of Rett Syndrome research, analyzing potential new therapeutic targets.

Fall 2014 - Spring 2015

During my third year, I collaborated with the Faundez lab at Emory on some of their cell biology papers. I am co-author on two papers that were published in my third year. One reported on copper sensitivity in dysbindin null animals, suggesting copper toxicity may play a role in schizophrenia. The other paper reported on NSF and dysbindin interactions as they pertain to synaptic plasticity.

During my fifth year at Agnes, with the support of internal grant money from generous donors to Agnes Scott, I published a manuscript with students (Miranda Arnold, Rebecca Cross, Kaela Singleton, Hannah Rudolph, Martha Vorder Bruegge, Andrea Sweatmen, Cecilia Garza, and Eli Whisnant) that examined the role impact of BLOC-1 expression on GABAergic interneuron expression in the hippocampus. I also worked with Hannah Rudolph to publish a review of similar genetic mutations in the endosomal pathway observed between Autism Spectrum Disorder and Schizophrenia. Finally, I published my third manuscript of the year with students (Miranda Arnold, Kaela Singleton, and Rebecca Cross) describing the role of BLOC-1 assoiated neuronal AGAP1 in endosomal trafficking and dendritic morphology and outgrowth.

Future Plans for Personal Research

As I move forward in my career, I am committed to continuing independent research in my lab, as well as using that research to generate peer-reviewed publications and scientific meeting presentations. Experiences like this not only allow me to continue research in neurodevelopmental biology, but these experiences allow students to identify what they want out of their future careers and prepare them for additional experiences that are necessary for further education. I will continue to offer Mentored Research (BIO 440) sections with at least one section offered each academic year, allowing students the opportunity for inquiry based research. I will also continue to publish my results in respected peer-reviewed journals furthering the scientific profile of the college.
