Mercy Sammy
Graduate Student Researcher, GRO
Building Envelope Materials Research Group

Mercy Sammy joined ORNL’s Building Envelope Materials Research Group as a Graduate Student Researcher on January 16, 2024.

Mercy is currently pursuing her Ph.D. in Computational Science with a concentration on System Engineering at Tennessee State University (TSU). Her master’s research specialized in Rechargeable Cement-Based Batteries, specifically focusing on Electrochemical Impedance Spectroscopy (EIS) testing for the anode and cathode, electroplating, and the charging and discharging cycle of the cement-based battery. Furthermore, Mercy has actively contributed to an augmented reality project aimed at analyzing and comprehending complex building heating, ventilation, and air conditioning (HVAC) equipment types. Her previous research topics also include geothermal heat pumps and the design of HVAC systems. This includes the meticulous selection of appropriate equipment based on calculations and the establishment of a thermal comfort envelope for both residential and commercial buildings.

Mercy is an active member of the American Society of Mechanical Engineers (ASME), Society of Women Engineers (SWE), and the Deloitte Mentorship Program. Moreover, she is the American Society of Heating, Refrigerating and Air-Conditioning Engineers (ASHRAE) student president at TSU.

In her new role at ORNL, Mercy will be mentored by Philip Boudreaux while she contributes to the refraction-based air leak detector (ALD) and the microwave moisture detector (MMD) projects. The ALD locates air leaks through the building envelope and measures their flow rates using off-the-shelf cameras and advanced algorithms. Mercy’s role includes developing software for image analysis and validating their performance through laboratory experiments. The MMD measures the moisture content of materials within the building envelope without removing any of the envelope components. Mercy’s role will be to validate the performance of MMD prototypes.

Outside of her academic pursuits, she engages in diverse outdoor activities, such as hiking and running. Mercy's recreational preferences also encompass badminton and volleyball. During her leisure time, she finds enjoyment in watching movies, reading books, and exploring various activities that bring relaxation.
