Siobhan Rockcastle

Short CV

Siobhan is an Assistant Professor of Architecture at the University of Oregon, Director of the Baker Lighting Lab and co-founder of OCULIGHT dynamics, a company offering daylight design support to promote healthy indoor occupation. She explores topics at the intersection of architectural design, environmental dynamics, human perception, and lighting performance with a focus on well-being.  Her research uses both experimental design and building simulation to measure and evaluate the impact of environmental conditions on human subjects. Siobhan was awarded the 2021 ARCC New Researcher Award and was on the organizing committee of two SimAUD symposia as Scientific Chair in 2018 and General Chair in 2019.  She received her PhD in 2017 from the LIPID lab in the Doctoral Program in Architecture and Sciences of the City (EDAR) at the Swiss Federal Polytechnic in Lausanne, Switzerland (EPFL) where her dissertation was awarded with ‘special distinction‘.

Siobhan earned her professional BArch from Cornell University in 2008 and her SMArchS degree in Building Technology from MIT in 2011. Her previous academic experience includes assistant and full-time teaching positions at Cornell, Northeastern, MIT, and EPFL. Her professional work experience includes KVA matX in Boston, Snøhetta NY, MSR design in Minneapolis, Epiphyte lab in Ithaca, and Gensler NY.
