I am a systems thinker working at the intersection of building physics, sustainability, and human experience, combining practice and research to inform better decisions in the built environment.

Based in Melbourne, Australia, my work blends consultancy, applied research, and academic inquiry. I practise as both a professional engineering director and a doctoral researcher in architecture, with engineering work focused on building physics and sustainable design, and research exploring human–nature connection, biophilia, and biophilic design.

This page contains information and links to both my professional and academic work. Feel free to contact me for collaboration, talks, presentations, or advisory roles.

My surname has recently changed - I'm currently in the process of updating my various online identities. Much of my work was published under my previous name, Jason Gaekwad.

Professional Activities

I am a professional consultant specialising in Building Physics and Sustainability. I thrive on challenging conventions and pushing project performance beyond standard practice.

I’m interested in work where engineering decisions have consequences beyond compliance, influencing how people experience buildings and how projects contribute to environmental and social outcomes. I see engineering as a tool for shaping the future, including how assets perform over their lifecycle, manage risk, and create durable value for owners, investors, and users.

Much of my work involves helping clients navigate complex decisions where there is no single “right” answer. Rather than focusing on individual metrics in isolation, I take a systems view to understand how design choices interact across a range of technical and non-technical domains. I currently practice as a Technical Director at Inhabit, based in Melbourne, Australia.

Academic Activities

In addition to my consulting work, I am also a PhD candidate within the School of Architecture and Built Environment at Deakin University in Geelong, Australia. My research investigates how different people experience natural and built environments, with implications for human well-being, built environment design practice, and policy frameworks. Further information on my research is available here.

Please have a look at my GitHub for work-in-progress Python projects related to my academic work, including packages for conducting meta-analyses and analysing data from the Tobii Pro Glasses 3 eye tracking headset.

Personal Interests

Outside of my professional and academic commitments, I spend as much time as I can outdoors, hiking, rock climbing, and SCUBA diving — both exploring new places and increasing my understanding of the familiar. I also play guitar and love going to live music events, especially when they bring diverse individuals together in vibrant, creative spaces.
