Graduate Students:

Jason Rexroat

jason_rexroat.jpgJason is a graduate student pursuing a Master’s degree in Electrical Engineering. He joined the Space Systems Lab as a freshman in the Spring of 2009, and obtained his Bachelor’s degrees in Computer Engineering and Electrical Engineering in the Spring of 2013. He has worked on a variety of projects including: hardware design on the NanoRacks/CubeLab ISS payloads, operations lead for CubeLab ISS operations, payload design and chase teams for several balloon missions, software design on the SOCEM/ADAMASat suborbital CubeSat, hardware build on the KySat-1 orbital CubeSat, hardware/software lead on CubeLab Bus/AmesLab payload, and C&DH lead on KySat-2. His research focuses are hardware and software design for embedded systems and fault tolerant avionics.

Timothy Lim

Timothy joined the Space Systems Lab in June 2012. He received his BSEE from the University of Kentucky in May 2013 and is projected to receive a MSEE in December 2014. The projects he has previously been involved in are the AmesLab power board and KySat-2’s Command and Data Handling system. His current project is the development of a modular and scalable electrical power system for CubeSats, which includes solar panel design, battery management, and power distribution and control. His main research area is electronics design.

Undergraduate Students:

Alex Clements

Jacob Travis

Jacob joined the lab in the summer of 2013. He is majoring in Electrical Engineering and will get his B.S. in 2014, with the goal of working towards a Master’s degree after. He also has a Computer Science minor. His main interest is in automation. An ideal career for him would be in the fields of automated farming or autonomous vehicle development. Within the lab, he has worked with embedded linux systems as well as PCB Layout design.

Mary Walker

Mary is a Mechanical Engineering Senior who started at the Space Systems Lab in the spring of 2011. She has worked on multiple balloon missions, the CubeLab Standard Bus project, KySat-2 and 3-D printing with the lab. She recently completed an internship with NASA Johnson Space Center during January-July of 2013 where she worked with avionics systems as well as mechanical design, testing and analysis.

Mary Fralick

Mary is an undergraduate Mechanical Engineering major who started working in the lab in October 2012. She has contributed to the mechanical development and environmental testing of KySat-2. Mary has plans to graduate with a B.S. degree in December 2014.

Zach Porter

Zach joined the lab in March 2013. He is pursuing a BS in Electrical Engineering and has worked on the KBUS EPS system in the lab as well as general board layout and design.

Rachel Nevill

Rachel did an internship with the lab in the fall of 2011, and became a member in June 2013. She is a Senior in Mechanical Engineering. Rachel works a lot with the 3-D printers.

Steve Alvarado

Steve is a Senior majoring in Electrical & Computer Engineering and began working for the University of Kentucky Space Systems Lab in the Summer of 2010. As a former Business, Journalism, and Astronomy major his interests remain diversified but has recently focused his attention on Digital System Design, Signal Processing, and Embedded Programming. He has been active in a variety of Lab projects including the Cubelab Bus Standardization and co-leading the construction of UK’s second operational ground station.

Micheal Rexroat

Michael joined the lab in the summer of 2013. He is majoring in Computer Engineering with the goal of getting his B.S. in 2016. He has been involved with development of the KySat-2 Ground Station Software, as well as APRS board design and layout for balloon missions.
