Hello, my name is Kamya Lapsley. I am from Fishers, Indiana, and I will be a senior at Kent State University in the fall. I am a Chemistry major with a concentration in Pre Med. After obtaining my undergraduate degree in the spring, I plan on completing a post baccalaureate research program for a year or two before applying to MD/PhD programs. I am working in Dr. Ashley Ross’s lab during my summer here at UC. The Ross lab is interested in developing electrochemical methods to study neurotransmitter signaling in the brain and immune system, developing microfluidic platforms for probing brain and brain-immune interactions, and developing new sensors for protein analysis ex vivo. With my graduate mentor Blaise Ostertag, we are using waste coffee grounds to make porous carbon. We are then taking this porous carbon and modifying carbon-fiber microelectrodes that are used in the lab for Fast-scan cyclic voltammetry (FSCV) with it. FSCV is used for the real-time detection of neurotransmitters, such as dopamine, on the subsecond time scale. Our hope with using the porous carbon to modify the carbon fiber microelectrodes is that ultimately there is an increase in sensitivity of the microelectrodes.

From Cincinnati, Ohio, Shania Smith, a recent graduate from Cincinnati State Technical and Community College and anticipating neuroscience: neuropsychology junior at the University of Cincinnati. She aspires of attending medical school upon completion of undergraduate school and becoming a Dermatologist.
This summer, Shania is working under Audrey Pumford in Dr. White’s research group. She is investigating collision dynamics during electrooxidation of single nanoparticles. Specifically, she is observing collisional behavior of both freely diffusing and tethered silver and platinum nanoparticles using amperometric methods. The ultimate goal behind her work is gaining knowledge about interactions of particles on a surface so she can create sensing platforms capable of detecting single molecules.

Erin Gannon is a Rising senior at Ohio University in Athens Ohio, where she is studying Forensic Chemistry. This summer she is working under the guidance of Chethani Ruhunage in the Alvarez lab studying methods and tools of organic materials chemistry, and electrochemistry to understand nanometer-scale phenomena and invent solutions and technologies for neuroscience, monitoring water quality, and energy storage. Her assigned project this summer is based around an engineering concept that will hopefully be able to be used as an electrode array to further understand the dopamine influence in neuroscience. Specifically, she is focusing on utilizing nanofibers, polymer, and the creation of a mold to fabricate multiple electrode arrays at once. The outcome of this engineering project is to manually create multiple electrode arrays to make the detection of dopamine within human bodily fluid samples more efficient and easier to analysis. Dopamine detection in a human blood sample using this manually built electrode array will utilize cyclic voltammetry technique and less sample fluid then the commonly used open ended CNT fiber electrode. The cyclic voltammetry method will detect the dopamine amount in a blood sample allow the study of neurons to be conducted.
