CAER Mentors

Engineers and scientists at the Center for Applied Energy Research at the University of Kentucky investigate technologies that reduce the impacts of energy utilization. Watch this short video for an overview of the UK CAER.

 

Courtney McKelphin is a junior Chemical Engineering student whose research experience at CAER, leadership position in the UK student chapter of the National Society of Black Engineers (NSBE), and experience as peer tutor make her an ideal peer mentor.

Courtney McKelphin

Courtney McKelphin, who is originally from Saint Louis, joined UK's Chemical Engineering program in 2013, being awarded both the William C. Parker and the UK Provost Scholarships. Since the spring of 2015 Courtney has been doing research within the Biofuels group of CAER, where her work focuses on the extraction of lipids from algae and the conversion of lipids to fuel-like hydrocarbons. While at CAER, Courtney has procured support for her research – in the form of grants from the UK Office of Undergraduate Research and the Research Scholar Programs of the KY NSF EPSCoR (which has featured Courtney's work commissioning a fixed bed reactor purchased with EPSCoR support) – and presented her results in a number of venues. In addition, Courtney has a strong service record, as she has been a peer tutor since 2014, participates in a number of professional societies – including the National Society of Black Engineers (where she currently serves as vice-president of the UK student chapter) – and has volunteered for a number of the community outreach activities led by CAER. Outside of school and work, Courtney enjoys riding motorcycles, cooking, baking, shopping, and traveling.
