About me
Hello, Iām Jialeiš. Iām working as a Postdoctoral Research Associate in the Building Energy and Environment Division at the National Institute of Standards and Technology (NIST). My research focuses on developing innovative technologies and strategies for sustainable and healthy buildings. Currently, my work at NIST is dedicated to evaluating and improving indoor air quality (IAQ), ventilation, and human health in buildings, and Iām collaborating with colleagues including Stuart Dols, Brian Polidoro, Andy Persily, and Lisa Ng.
Prior to my current role at NIST, I pursued my PhD in Mechanical and Aerospace Engineering at Syracuse University under the guidance of Prof. Jianshun āJensenā Zhang in the Building Energy and Environmental Systems Lab (BEESL). During my doctoral studies, I engaged in various research initiatives focusing on building energy and environmental systems, backed by government agencies and industry leaders such as the Department of Energy (DOE) and Carrier. My work involved close collaboration with experts in the field, including Prof. Bing Dong, Prof. Bess Krietemeyer, Michael Birnkrant, and Peter McKinney, contributing to projects that intersected architectural design, energy efficiency, and environmental quality.
Throughout my research journey, Iāve delved into a range of topics spanning
- Indoor Air Quality (IAQ) and Public Health, where I explored building IAQ and how it affects human health through modeling and exrimental efforts;
- Air Cleaning Technology, focusing on the innovation and efficacy of technologies that purify indoor air and benefit human health;
- Urban Environments, assessing the influence of building and urban designs and systems on urban environments; and
- Building Energy Efficiency, with a dedicated effort toward optimizing energy consumption in building infrastructures.
My academic contributions to these areas are documented in one book chapter, 17 journal articles, and a collection of conference papers, which have collectively received over 680 citations. You can review my research impact on my Google Scholar profile.
I am actively seeking academic positions that align with my expertise in building energy and environmental systems, hoping to further contribute to the field through both research and teaching.
