After completing the military service, Ming-Hao came to Colorado State University to pursue his M.S. degree in 2015. His master’s project focused on developing a replacement of the lock-in amplifier for the Fluorescence Lifetime Microscopy. Ming-Hao now is a Ph.D. student in the ECE department, and his research focuses on development of microfluidic devices for measuring the metabolic rate of cells, such as oxygen and glucose consumption. In his free time Ming-Hao enjoys photography and watching funny videos on YouTube.


Ryan Way completed a B.S in Electrical Engineering at Colorado State University in May 2021 and is currently pursuing a Master’s degree in Electrical Engineering. His interests lie in mixed-signal circuit design, VLSI design, and system level electronic device development. Ryan started working in the BLISS lab for his undergraduate senior design project where he helped with the design and implementation of various PCB boards for the Smart Well Plate project. His passion for this project led him to pursue a master’s degree where he can continue the progress of the Smart Well Plate project. With the help of his colleagues in the lab he is currently working to add electrochemical impedance spectroscopy capabilities to the Smart Well Plate through an attachable USSING chamber. This addition would allow the device to record the electrical impedance and pH of intestinal tissue.

Outside of working on research, Ryan enjoys golfing, snowboarding, traveling, and watching movies in his free time.

Michael Siegel is a graduate student pursuing his Master’s degree in Electrical Engineering. He received a BS in Electrical Engineering at Colorado State University in May 2019, and an AS in Automotive Technology from Front Range Community College in May 2015. For his senior design project, Michael was part of the Bio-Analysis project which won first place in the CSU 2019 E-days. Both the project and support from his advisor inspired Michael to continue into graduate school and work with biosensors. Michael will be working as part of Dr. Tom Chen’s group to develop and test various biosensors which can simultaneously measure different aspects of cell metabolism. In his spare time, Michael enjoys RC hobby vehicles, PC gaming, and restoring antique cars.

Jacob Alfieri completed a B.S. in Electrical Engineering and Biomedical Engineering at Colorado State University in May 2020.  His senior design project had a team consisting of Electrical, Mechanical, and Biomedical engineering students to develop the Smart Well-plate: a handheld device that could measure metabolic responses of tissues and cell cultures via an electrochemical sensor system.  Jacob is now pursuing an M.S. in Electrical Engineering with his graduation project being a continuation of the Smart Well-plate.  His hope with the project is to development a microfluidic system for the Smart Well-plate to allow extended real time measurement of metabolites being produced by the cell culture, and to integrate the sizing of the device into the framework of current well-plate machines in the field.  In his free time, Jacob loves to bike around Fort Collins, play online games with friends, and play the piano.

Graduate Students Worked in the Lab and Graduated within the Last 5 Years

Daniel Ball

Daniel Ball completed a B.S in Computer Engineering in student studying at Colorado State University in May 2017, and M.S. in Computer Engineering in 2021. As a senior design project he worked with a team of computer engineering and mechanical engineering students to develop BioBox: a low cost environmentally regulated bioanalysis chamber. His graduate project is a continuation of the BioBox, bringing the system to a consumer ready product. The completed device will have improved environmental controls, a digitally controlled microscope and stage with dark field and fluorescence microscopy capabilities. He is also designing software, including computer vision to aid in automated experiments and a user interface for interacting with the system.

Prior to attending CSU, Daniel was an Electronics Technician in the United States Navy, where he performed preventive and corrective maintenance on military communications equipment and later worked as a systems administrator for an enterprise network spanning the east coast. While enlisted, he was was stationed in Iceland, Japan, Illinois, and Virginia.

Outside of school, Daniel has a range of interests including woodworking, camping, photography, and gaming.

Caleb Begly

Caleb Begly was a Master’s Degree EE Student at Colorado State University. He received a Bachelors of Science Computer Engineering degree from Colorado State University in May 2017, and an Associate of Science in Physics in December 2014. The undergraduate degree focused on hardware classes and VLSI to build skills in digital systems design in addition to the core Computer Engineering coursework. For the senior design project, he worked on the interdisciplinary BioBox environmental chamber project which won first place in the CSU 2017 E-Days. This project, coupled with the GAUSSI classes, sparked an interest in biosensing. While working on the Master’s degree, Caleb developed multiplexed impedance sensing using the third generation CMOS biosensor chip. The goal was to produce the methods and equipment needed to perform multiple lab tests simultaneously on the chip.

Caleb enjoys hiking, biking, playing the mandolin, PC gaming, and working on hardware and software projects in his spare time.

Nick Grant is originally from Illinois and has a background in Mechanical Design and Industrial Engineering. Nick came to CSU in 2012 to pursue a undergraduate degree in Electrical Engineering. He focused on VLSI and digital system design during his undergraduate work with an interest in integrated analog / mixed signal design. As a senior project he designed a four layer mixed signal circuit board to interface the third generation CMOS Biosensor to other devices where shielding, noise, and signal integrity were key. Nick has completed several computer science classes to understand systems from the user interface down to the physics of the transistor.

During his MS program in Electrical Engineering, Nick researched ways to apply his integrated systems knowledge to the biomedical field to help improve research and medical care. Working with an interdisciplinary group of chemists and biologists, Nick’s focus was on helping to develop a complete Lab on Chip system.
