**About the Editors**

#### **Ashok Kumar**

Dr. Ashok Kumar (Distinguished University Professor Emeritus). Ashok's research work has focused on finding innovative solutions to fundamental and applied problems in air quality modelling, risk assessment and environmental data analysis. His recent projects include mobile source modelling, pollution prevention, and indoor radon detection in Ohio. He has received 44 grants from industry and regulatory agencies. He is the author or co-author of more than 450 peer-reviewed papers, book chapters, conference papers and reports. He has edited three conference proceedings and three books, and has additionally co-authored five books. He was the guest editor of 11 journal issues by different publishers. The work of his group on model evaluation, indoor radon, indoor air quality in public buses, biodiesel, and modelling techniques has received extensive citations in the literature. He has served as a reviewer for several journals, publications, and corporations. He received Layman A. Ripperton Award for distinguished achievement as an educator in the field of air pollution control in June 2003 from the Air and Waste Management Association (A&WMA), and is now an honorary member of A&WMA.

#### **Alejandro Moreno-Rangel**

Dr. Alejandro Moreno-Rangel (Lecturer in Building Performance Evaluation and Net Zero Design). Alejandro has extensive experience in sustainable architecture, particularly in Passivhaus buildings and their connections to health and human behaviors. Through this work, Alejandro explores the architectural design, energy efficiency methods, passive techniques and their impact on the indoor environment—indoor air quality (IAQ) and thermal comfort. He particularly focuses on these aspects of homes and their relation to the urban environment with the aim of creating healthy homes. Architecture has responded well to climate change, mitigating the effects of the built environment and achieving net zero carbon emissions. However, its impact on human health is often left aside. Alejandro's approach to architectural design seeks to improve the quality of life and health for all citizens, delivering net zero interventions that take a "whole house" approach, improving IAQ and comfort. Alejandro's research uses design research methods to explore the interactions of building occupants' behavior and net zero buildings to deliver healthier indoor environments, considering the impact of bio-psychological-social aspects of health, climate change, and energy efficiency method interactions. Alejandro's research interests also extend to the use of low-cost sensors as research tools, in retrofitting and in maintaining a net zero policy.

#### **M. Amirul I. Khan**

Dr. M. Amirul I. Khan (Lecturer in Environmental Fluid Mechanics) has extensive experience in innovative computational approaches for applications of wall-bounded turbulent flow modelling to indoor built environments and outdoor environments. He has expertise in mathematical modelling, numerical optimization methods and high-performance computing. His expertise in turbulent flow modelling allowed him to lead and co-lead several inter-disciplinary research projects, including a CONFAP-Newton Fund award, EU-GeoTech, EPSRC HECOIRA, UKRI GCRF COVID-19 grant. He is currently co-leading the computational group of Leeds Institute for Fluid Dynamics (LIFD), which is a university-wide hub to facilitate world-leading research and education in fluid dynamics. He has developed computational fluid dynamics (CFD)-based optimization approaches to design healthcare environments and developed the novel massively parallel lattice Boltzmann (LBM)-based method for real-time building environment simulation, which was recognized with the Best Paper Award. He has also developed a novel sensor data assimilation-based indoor air quality (IAQ) forecasting technique. He has over 50+ peer-reviewed journal and conference papers across top journals in fluid mechanics and computational methods, including leading journals for the built environment.

#### **Michał Piasecki**

PhD, D.Sc. eng. Michał Piasecki is a senior researcher at the Building Research Institute (ITB). In 2009, he obtained a doctoral degree in civil engineering (sustainable assessement). From 2010 to 2021 he joined the Department of Thermal Physics, Acoustics and Environment at ITB as an assistant professor. From 2016 to 2019, he served as head of deparment. In 2021, he obtained a doctor of science degree (habilitation) in Civil Engineering from the Lodz University of Technology (indoor comfort). Currently, he is employed as the Institute's professor. Piasecki specializes in issues of sustainable construction concerning buildings and products related to VOC emissions, the assessment of indoor environment comfort and quality (IEQ), indoor air quality (IAQ), carbon footprint (CF) and economic assessment (LCC), as well as determinations of the thermal and moisture properties of buildings and thermal comfort (PMV/PPD). He is the Chairman of the KT 307 Committee at Polis Standards PKN for Sustainable Construction, a member and expert of numerous scientific organizations in Poland and Europe and a thematic editor and a reviewer in several scientific journals. His achievements include over 130 peer-reviewed publications, including 22 in the Web of Science database with citation h-index = 13. Recent achievements include the creation of a model for assessing the indoor environment of buildings. In 2019, he completed a research internship at the Lviv University of Technology. In the last dozen or so years, he help to lead and participate in several scientific and research projects, including European Commission research projects in the prestigious FP7, Erasmus+, Norway Grants and Horizion programs (energy performance, IAQ, IEQ, sustainable building).
