Academic background

Sebastian received a Bachelor’s degree in Electrical and Electronics Engineering from Universidad de los Andes, Colombia, in 2008. He later interned for CERN in Geneva, Switzerland, 2008, and for Asylum Research, in 2009. He completed an MPhil degree in Micro and Nanotechnology at the University of Cambridge, UK, in 2010. He was a lecturer in Electronics at Universidad de los Andes in 2010-2011. He later completed a Doctorate in Materials in the Semiconductors Group funded by a Clarendon Scholarship, in 2015, researching novel methods to maximise surface passivation for silicon solar cells. After, he was awarded an EPSRC Postdoctoral Research Fellowship to deepen the understanding and advance industrial deployment of new methods of silicon surface passivation, which he held from 2015 to 2018. At the same time, he became a Junior Research Fellow at Wolfson College, Oxford, holding his JRF until 2021. Since 2019, he has been a Royal Academy of Engineering Research Fellow in the Oxford Materials Department. From 2021, he is an Associate Professor of Materials in the Materials Department and a Stipendiary Lecturer in Materials Science at St Anne’s College, Oxford. From 2022 to 2023 he held a Hugh Price Research Fellowship at Jesus College Oxford. From 2023, he is an Associate Professor of Materials and Tutorial Fellow of St Anne’s College Oxford.
